Figure 1-3 shows an exploded view of the SA70R-AK enclosure. The major subassemblies of the SA70R-AK enclosures are as follows: · Chassis · Operator control panel (OCP) · Transition board assemblies (TB1-M and TB2) · Power supply · Fan assemblies (two) · Cable harness · Canister lock/release mechanisms (four) · Canister ready indicators (four) · RA7x-RK removable disk drives (up to four) · SDI cables Each RA7x-RK removable disk drive fits into one of four recessed positions in the front of the enclosure. The canister is secured in the enclosure by the canister lock/release mechanism. The OCP is mounted on the front of the enclosure above the canisters and plugs into the internal transition board assembly #1 (TB1-M). TB1-M connects the OCP to transition board assembly #2 (TB2). TB2 sits internally above the canisters and transfers drive signals to the OCP through TB1-M. The power supply and fan assemblies are mounted in the rear of the enclosure behind the canisters. A cable harness containing interconnecting cables and internal SDI cables runs through the enclosure chassis. NOTE The TB1-M used in the SA70R-AK enclosure is not interchangeable with the TB1 used in the SA7x enclosure. The boards are of different designs and operate correctly only when installed in the appropriate enclosure. Digital Internal Use Only 1-6 Introducing the SAx05 Storage Arrays Figure 1-3 Exploded View of the SA70R-AK Enclosure The enclosure power supply provides operating power to the major subassemblies of the enclosure. The power switch for the enclosure is located on the rear panel of the enclosure. Each RA7x-RK removable disk drive is powered and controlled independently. You can operate a disk drive with other disk drive positions unoccupied or while maintenance is being performed on another drive. The power switch for each disk drive is activated automatically (by a microswitch in the canister lock/release mechanism on the enclosure) when you insert the canister into the enclosure. The power switch is deactivated when you move the lock/release handle to the right to remove the canister. Next to each canister lock/release handle on the front of the enclosure is a canister ready indicator that lights when the RA7x-RK removable disk drive is powered up and ready for operation. Indicator symbols show which set of switches and indicators on the OCP correspond to that particular drive position. Digital Internal Use Only Introducing the SAx05 Storage Arrays 1-7 The RA7x-RK removable disk drives are operated from four sets of switches and indicators on the OCP. Each control set operates one disk drive in the enclosure. Two fan assemblies circulate cooling air throughout the interior of the SA70R-AK enclosure. The air is drawn into the enclosure through the front and is exhausted at the rear. The fans operate at two speeds. When the temperature exceeds 29°C (85°F) the fans operate at high speed; otherwise, they operate at normal speed. Also, if one fan is not operating, the other fan accelerates to high-speed. Additional information about the SA70R-AK enclosure subassemblies can be found in (desc_chap). 1.6 RA7x-RK Removable Disk Drives Overview The RA7x-RK family of removable disk drives includes the RA70-RK, RA71-RK, and RA72-RK. The RA7x-RK disk drives are designed for the SAx05 storage arrays. They can be installed into and removed from the SA70R-AK enclosure on a regular basis. Once removed from the enclosure, these disk drives can be stored or transported. A canister carrying case (part number RA70X-AK) is available for transporting a disk drive off site. The RA7x-RK disk drive consists of an RA70, RA71, or RA72 disk drive mounted in a metal canister. The disk drive canister features modular components that can be replaced with minimum downtime.

Unpack the two filler panels. 3. Remove and save the four 10-32 x 1/2-inch screws (two on each side) and the two wing nuts from each filler panel. 4. Install the filler panels by connecting them to the top and bottom spreaders, as follows: NOTE One filler panel has two rectangular openings; the other panel is solid. If cables will exit at the bottom of the cabinet and be routed under a false floor in the computer room, install the filler panel with the rectangular openings at the bottom of the cabinet, and the solid panel at the top. If cables will exit at the top of the cabinet and be routed through the computer room ceiling, install the filler panel with the rectangular openings at the top of the cabinet and the solid panel at the bottom. a. Place the appropriate filler panel on top of the top spreader. b. Push the two captive studs on the filler panel through the two slots in the spreader. c. Move the filler panel toward you until the captive studs stop at the ends of the slots. d. Install and tighten the two wing nuts on the captive studs. e. Repeat this procedure to connect the bottom filler panel to the spreader. 5. Loosen the three 1/4-20 x 3/4-inch screws located on the top, middle, and bottom of each side panel. 6. Pull the side panels toward you until the U-shaped screw holes at the top and bottom of the side panels line up with the screw holes on the sides of the filler panels. 7. Reinstall the eight 10-32 x 1/2-inch screws (four from each filler panel) to secure the side panels. Insert two at the top and two at the bottom of each side panel and tighten. 8. Determine how far the cabinet rear access panel will need to be extended. This decision depends on the number of enclosures and drives installed in the cabinet: · If the cabinet is fully populated, the rear access panel must be fully extended to accommodate the cables. · If only a few enclosures and drives are installed, the rear access panel can be partially extended. To use a fully extended rear access assembly, leave the assembly fully extended and tighten the three 1/4-20 x 3/4-inch screws on each of the two side panels. To use a partially extended rear access assembly, perform the following procedure: a. Loosen the two wing nuts on each filler panel. b. Gently push the rear access panel back into the cabinet until you encounter resistance. c. Retighten the wing nuts. d. Tighten the three 1/4-20 x 3/4-inch screws on each of the two side panels. 9.

After applying power to the SAx05 enclosure, perform the post-installation checkout procedure as follows: 1. Verify power supply operation by making sure all enclosure fans are operating. Do this by checking for airflow out of the rear of each enclosure. If the fans are not operating: a. Verify that all power and interface connections on the rear of the enclosure are correct and secure. b. Verify that the power supply is firmly seated in its connector. NOTE If one of the fans is not operating, the two disk drives situated in front of that fan will not operate. 2. Check to see if any of the fault indicators on any of the enclosure rear panels are lit. If a fault indicator is lit: a. Turn off power to that enclosure for 10 seconds, then turn the enclosure back on. b. If the fault indicator lights again, refer to Chapter 6 and contact your Digital Customer Services engineer. 3. Verify power application to each occupied disk drive position by checking the canister ready indicator lights. If a canister ready indicator is not lit, verify that the disk drive is correctly inserted in the enclosure. (Refer to Section 4.5.) Digital Internal Use Only Unpacking and Installing the SAx05 Storage Arrays 2-17 Applying power to the disk drive starts the drive's internal power-on diagnostics. These diagnostics are signaled at the OCP by the following sequence of indicator lights: a. All indicators light for about 8 seconds. b. If the drive completes the power-on diagnostics without detecting a fault, all indicators go out. c. If the Fault/Set No. indicator remains lit, the drive has detected a fault. Press the Fault/Set No. switch twice to clear the fault. If the indicator remains lit, refer to Chapter 6 for fault recovery procedures. 4. Perform an OCP lamp test to ensure the LED state indicators are working properly. Do this by pressing and holding the Fault/Set No. switch for each occupied drive position; all lamps should momentarily light. If lamps do not light, ensure the OCP is seated properly and power is applied to that disk drive, then try the test again. 5. Set the drive unit number for each disk drive in the storage array. (Refer to Section 2.11.) 2.11 Setting the Drive Unit Numbers During Installation The drive unit number is the number the system uses to identify the drive. This number is automatically read by the drive at power up and after the number has been reset. You can set the drive unit number for any disk drive at the OCP. Once the number is in the drive, the system controller reads it according to the controller 's protocol. Refer to Section 3.8 for additional information about setting drive unit numbers during routine operation. Use the following procedure to set the drive unit number during an initial installation (see Figure 2-11): CAUTION Be sure that no two disk drives in your system have the same drive unit number. Using the same drive unit number for two disk drives causes a controller fault and results in both drives spinning down. 1. Locate the Unit Select switch in the upper right corner of the OCP. Carefully press the Unit Select switch with a pointed object such as a pen or small screwdriver. The unit select numbers for all powered-on drives in the enclosure flash to indicate that the OCP is in unit select mode. 2.

Digital Internal Use Only 3-8 Operating the SAx05 Storage Arrays The Fault/Set No. switch is a momentary push button. When you press the switch and hold it, it is set; when you release the switch, it is reset. · Run--Pressing the Run switch causes the drive to spin up. The yellow Run indicator lights after the drive spindle reaches operating speed. Pressing the Run switch again releases the switch and causes the drive to spin down. The yellow Run indicator goes out only after the drive spindle comes to a complete stop. · Fault/Set No.--Pressing and holding the Fault/Set No. switch during normal operation causes all OCP indicators to light as a lamp test. When a fault condition is detected in a disk drive, the red Fault/Set No. indicator lights. Pressing the Fault/Set No. switch once after a drive fault takes the drive off line and causes all indicators in the drive's control set, including the Fault/Set No. indicator, to blink an error condition code. Pressing the Fault/Set No. switch a second time clears the error code and commands the drive to attempt to clear the error and return on line. The Fault/Set No. switch is also used to set the drive unit number, as described in Section 3.8. · Ready--The green Ready indicator lights to show that the drive is ready for read/write operations. This indicator is activated only after the Run switch is set and the yellow Run indicator is lit. The Ready indicator remains on during normal operations but may blink or go out during heavy disk usage. During spinup, the drive performs diagnostics and servo calibrations. The Ready indicator must light within 60 seconds after you press the Run switch; failure to do so indicates a problem in the drive. · Unit No.--The unit number for the disk drive is displayed next to the Ready indicator. The unit number can be set to any number between 000 and 255, as described in Section 3.8. Placement of unit numbers in an actual installation is shown in Figure 3-4 (unit numbers 000 through 003 in this example). · Write Protect--Setting the Write Protect switch disables writing to the drive. This function keeps the drive data from being overwritten and lost. The yellow Write Protect indicator lights to show that a drive is write protected. The drive may also be write protected by a system controller command; this also causes the Write Protect indicator to light. · A and B--You enable ports A and B using the port A and port B select switches. Yellow indicators in each switch light to show that the system controller has selected the port. The Ready and Run indicators remain lit during normal operation, although the Ready indicator may flicker during heavy seek activity. The Write Protect indicator is on if the drive is write protected and off if the drive is write enabled. The port A and B indicators light only while their respective ports are selected by the system controller. 3.4.2 Canister Ready Indicators A canister ready indicator is located above each of the disk drive positions on the front of the SA70R-AK enclosure. Four conditions are necessary for the indicator to light: · AC power must be available to the SA70R-AK enclosure. · The SA70R-AK enclosure power switch must be on. · The RA7x-RK removable disk drive must be properly inserted in the enclosure. · Power must be enabled to the disk drive through the microswitch in the canister lock/release mechanism. · The power supply must be supplying the correct voltage to the disk drive. The symbol on each canister ready indicator corresponds to the related set of switches and indicators on the OCP. Digital Internal Use Only Operating the SAx05 Storage Arrays 3-9 Inserting an RA7x-RK removable disk drive automatically connects power to that disk drive and causes the drive to run a power-up self test.

This number is automatically read by the drive at power up and after the number has been reset. You can set the drive unit number for any disk drive at the OCP. Once the number is in the drive, the system controller reads it according to the controller 's protocol. NOTE The drive unit number is stored on transition board #2 (TB2). The disk drive does not maintain the unit number when the drive is moved to a different position in the enclosure. However, the drive unit number is saved during a power failure by the nonvolatile storage on TB2. Use the following procedure to set the drive unit number for a selected drive during routine operations: CAUTION Be sure that no two disk drives in your system have the same drive unit number. Using the same drive unit number for two disk drives causes a controller fault and results in both drives spinning down. 1. Dismount the selected disk drive and take it off line.

Procedures for recovering from a fault condition are also included. Table 6-1 lists problems you may encounter and the section in this chapter that discusses how to troubleshoot that problem. Table 6-1 Problems and Troubleshooting Section References ------------------------------------------------------------ Problem Section Reference ------------------------------------------------------------ The entire enclosure is inoperative. Refer to Section 6.2. The canister ready indicators are flashing. Refer to Section 6.3. The canister ready indicator does not light when a disk drive is inserted. Refer to Section 6.4. The unit numbers on the operator control panel (OCP) are flashing. Refer to Section 6.5. The disk drive is not communicating with the controller or not responding to OCP commands. Refer to Section 6.6. The enclosure fans are noisier than usual. Refer to Section 6.7. The Fault/Set. No. indicator on the OCP is lit. Refer to Section 6.8. ------------------------------------------------------------ Digital Internal Use Only 6-1 6-2 Troubleshooting 6.2 Troubleshooting an Inoperative Enclosure If an enclosure is not operating, check the power supply fault indicator on the rear of the SA70R- AK enclosure. The fault indicator is visible, when lit, through holes in the upper right corner of the enclosure power supply. (See Figure 6-1.) The fault indicator lights red to indicate an overtemperature or overvoltage condition in the power supply. Figure 6-1 Rear View of the SA70R-AK Enclosure If the fault indicator is lit: 1. Immediately turn off (0) the power switch located on the rear of the enclosure and check for airflow obstructions. 2. If you suspect the enclosure has been exposed to an overtemperature condition, allow the enclosure to cool, then turn it back on. If the enclosure returns to normal operation (the fans operate and the fault indicator does not light), an overtemperature condition is the likely cause of the failure. Refer to Table 1-2 for recommended environmental limits and ensure that the operating site complies with these limits. If the enclosure has not been exposed to an overtemperature condition, leave the power switch off for 10 seconds, then turn it back on (1). a. If the fault indicator does not light, resume normal operation. b. If the fault indicator lights, call your Customer Services engineer. Digital Internal Use Only Troubleshooting 6-3 If the red fault indicator is not lit: 1. Verify site power by checking other equipment on the same line and the circuit breakers to the cabinet. 2. Verify that the enclosure power plug is connected to the line outlet in the cabinet. 3. Verify that the storage array's power plug is connected to the site's line voltage outlet. 4. Verify that the line voltage selector switch on the rear panel of the enclosure is set to the correct voltage. (See Figure 6-1 for the location of the line voltage selector switch.) 5. Verify that the 881 power controller and the enclosure power supply are turned on. 6. Check for an overvoltage condition in the power supply by removing power to the disk drives. Do this by releasing the lock/release handle (move the handle to the far right) for each disk drive canister. a. If the enclosure fans start, proceed to step 3 in Section 6.3. b. If the enclosure fans do not start, contact your Customer Services engineer. 6.3 Troubleshooting Flashing Canister Ready Indicators Flashing canister ready indicators indicate an overcurrent condition at the power supply output. If the canister ready indicators on the front panel of the enclosure are flashing: 1. Reset the OCP switches as follows: a. Deselect both ports A and B. b. Press and release the Run switch for that disk drive. (See Figure 6-2.) c. Repeat this step for all drives in the enclosure. 2. Remove power to the disk drives by releasing the lock/release handle (move the handle to the far right) for each disk drive. 3. Restore power to the disk drives by pushing them in one at a time. a. If the canister ready indicator lights steadily when you insert a disk drive, that drive is not causing the overload. b. If the canister ready indicator flashes when you insert the disk drive, that disk drive is probably causing the overload. 4. Insert the disk drive that caused the indicator to flash into a different opening in the enclosure. a. If the indicator for that opening flashes, the disk drive is at fault. Remove the defective disk drive and resume operation. b. If the indicator for that opening does not flash, the opening that had the flashing indicator is at fault. Call your Customer Services engineer. Digital Internal Use Only 6-4 Troubleshooting Figure 6-2 Front View of the SA70R-AK Enclosure Digital Internal Use Only Troubleshooting 6-5 6.4 Troubleshooting a Nonlighting Canister Ready Indicator If a canister ready indicator does not light when you insert a disk drive: 1. Verify that the canister is fully seated in the enclosure and the lock/release handle has moved completely to the left. 2. Verify that the canister ready indicators for other occupied disk drive positions are lit. a. If the other canister ready indicators are not lit, verify power to the enclosure as explained in Section 6.2. b. If the other canister ready indicators are lit, insert another disk drive in the suspect position. · If the canister ready indicator lights, the original disk drive is probably at fault. Do not use the disk drive. · If the canister ready indicator does not light, the enclosure is probably at fault. Contact your Customer Services engineer. 6.5 Troubleshooting Flashing Unit Number Indicators If all the Unit Number indicators on the OCP are flashing, the panel has been placed in the unit select mode. Carefully press the Unit Select switch with a pointed object or small screwdriver to restore normal operation. 6.6 Troubleshooting a Noncommunicating Disk Drive If a single disk drive is not communicating with the system controller or does not respond to OCP commands (all other drives are normal): 1. Verify that the disk drive is properly inserted in the enclosure. 2. Verify that the appropriate port switch is selected. 3. Record any error code displayed on the OCP, as described in Section 6.8. 4. If the drive was previously on line: a. Dismount the drive from the system, take the drive off line, and spin it down by pressing the Run switch. b. When the Run indicator goes out, remove power to the drive by fully releasing the lock/release handle (move the handle to the far right). Removing power to the drive for 10 seconds resets the drive's circuits. c. After 10 seconds, restore power to the drive by pushing the canister in fully. 5. Verify that the SDI cable connectors from the host system are securely tightened at the cabinet I/O bulkhead. 6. Attempt to bring the disk drive back on line and restore normal operation. 7. If you still cannot bring the disk drive back on line, contact your Customer Services engineer. 6.7 Troubleshooting Noisy Fans If the enclosure fans seem noisier than usual, they are probably operating at high speed. When the temperature inside the enclosure exceeds 29 degrees C (91 degrees F), the fans automatically switch to high speed operation. Refer to Table 1-2 for recommended environmental limits and verify that your site complies with these limits. Digital Internal Use Only 6-6 Troubleshooting 6.8 Recovering from a Drive Fault Condition The RA7x-RK disk drive contains sophisticated circuits to detect and report fault conditions. These faults are reported to you through an error code displayed on the OCP. Your Customer Services engineer uses these codes and other error reporting mechanisms in the disk drive to pinpoint the source of a fault and return your disk drive to service in a minimal amount of time. If the Fault/Set No. indicator lights to signal that the disk drive has detected a fault, use the following procedure (see Figure 6-2): 1. Press the Fault/Set No. switch once to display an error code on the OCP. The error code is displayed as flashing indicators. 2. Record which indicators are flashing. Your Customer Services engineer will use this code to isolate the cause of the drive fault. NOTE While in the fault mode, the OCP indicators do not retain their normal function; they act only as error code indicators until you press the Fault/Set No. a second time. 3. Press the Fault/Set No. indicator again. This commands the drive to clear the fault and return to normal operation. a. If the fault clears, you may resume operation. Note the occurrence of the fault in the system log so it can be used in future system fault analysis. b. If the fault recurs, call your Customer Services engineer. 6-6 Digital Internal Use Only A Environmental Stabilization ------------------------------------------------------------ Environmental stabilization includes humidity and temperature stabilization. When the RA7x-RK removable disk drive arrives at your site or is temporarily removed from its normal operating environment, it must be environmentally stabilized prior to operation. The RA7x-RK removable disk drive can be stabilized inside or outside the RA70-CK carrying case. However, do not insert the canister into the SA70R-AK enclosure until it is fully stabilized. CAUTION Failure to environmentally stabilize the RA7x-RK removable disk drive could result in damage to the drive media or associated electronics at power-up. Environmental stabilization begins when the equipment enters the room where it is to be operated. If the equipment is new, remove the outer shipping carton and allow environmental stabilization time with the barrier bag still sealed and the desiccant in place. Refer to Table A-1 for minimum stabilization times. NOTE If condensation is visible on the outside of the canister, stabilize the disk drive in the operating environment for 6 hours or until the condensation is no longer visible, whichever is longer. If no condensation is visible on the outside of the canister, refer to Table A-1 for the correct environmental stabilization time.
