This chapter describes how to change the settings on the switch pack. If you have many options in your system, you may have to change the interrupt request (IRQ) line, the I/O address setting, or the memory address setting on the DEC EtherWORKS LC/TP board to create a compatible operating set. 2-1 2-2 Configuring the DEC EtherWORKS LC/TP Board 2.2 Default Settings The DEC EtherWORKS LC/TP board is shipped with the switch pack preselected (default settings) to work in most installations. These settings are shown in Table 2-1 and illustrated in Figure 2-1. Table 2-1 Default Settings on DEC EtherWORKS LC/TP Board ------------------------------------------------------------ Switch Position Function Meaning ------------------------------------------------------------ SW1 SW2 ON ON Sets the base memory address range. Sets the base memory address range to D0000 - DFFFF (hex). SW3 SW4 ON ON Selects the buffer memory size. Enables 64 Kbyte memory size. SW5 ON Sets the I/O memory address. I/O starting address set to 300 (hex). SW6 ON Enables or disables remote boot feature. 1 Remote boot disabled. SW7 OFF Sets the timeout period for the remote boot attempt. 1 Sets a 30 second timeout period. SW8 SW9 SW10 SW11 SW12 OFF OFF OFF ON OFF Enable IRQ2 Enable IRQ3 Enable IRQ4 Enable IRQ5 Enable IRQ7 IRQ5 enabled. ------------------------------------------------------------ 1 This feature requires that the optional ROM chip be installed; refer to Appendix B for more information. ------------------------------------------------------------ NOTE When the switches are depressed in the open position this means the switch setting is off. Configuring the DEC EtherWORKS LC/TP Board 2-3 Figure 2-1 DEC EtherWORKS LC/TP Board Switch Pack 2-4 Configuring the DEC EtherWORKS LC/TP Board 2.3 Check the Other Options You can set only one adapter board in the computer to use a specific interrupt request line, I/O memory address, or base memory address. If you do not know the settings for the other adapters: · Ask your system administrator for a list of the settings. · Check the adapter documentation for the possible settings. · Inspect the adapter boards to determine the actual settings. If you find that a conflict exists, you can change the appropriate setting on the DEC EtherWORKS LC/TP board. To do this, refer to the sections that follow. The switches being described are highlighted in the illustrations. 2.4 Memory Addressing Range and Size Selection (SW1 - SW4) Switches SW1 and SW2 select the memory addressing range. Switches SW3 and SW4 select the size of the system memory the DEC EtherWORKS LC/TP board uses. Table 2-2 lists the possible memory address ranges and the switch settings that select them. Only one adapter can be set to use a given memory address range. Check the documentation supplied with your personal computer and other adapters to determine memory address requirements. If other adapters in your computer use memory ranges that conflict with one of these ranges, select a range that is unused. Configuring the DEC EtherWORKS LC/TP Board 2-5 Table 2-2 Switch Settings and Memory Address Ranges ------------------------------------------------------------ Buffer Size SW1 SW2 SW3 SW4 Memory Addressing Range ------------------------------------------------------------ 64 Kbytes Off On On On C0000--CFFFF On On On On D0000--DFFFF (default setting) Off Off On On E0000--EFFFF 1 ------------------------------------------------------------ 32 Kbytes Off On Off On C8000--CFFFF On On Off On D8000--DFFFF Off Off Off On E8000--EFFFF 1 2 Kbytes 2 - - - Off - ------------------------------------------------------------ 1 Some PCs do not support the E0000 - EFFFF or E8000 - EFFFF memory address ranges; check your PC manual for this information. 2 At this time, Digital PCSA software does not support 2 Kbyte mode. ------------------------------------------------------------ NOTE Setting SW1 to the ON position and SW2 to the OFF position is an illegal configuration and can prevent the computer from working correctly. 2-6 Configuring the DEC EtherWORKS LC/TP Board The DEC EtherWORKS LC/TP board works best when the entire 64 Kbytes of network buffer memory is enabled for operation. Some option cards and system configurations do not permit the allocation of this amount of memory. Network performance is slower when you select 32 Kbytes or 2 Kbytes, but you can use the DEC EtherWORKS LC/TP board in configurations where address space is at a premium. Example: Figure 2-2 shows the settings for SW1 through SW4 that select the C8000 to CFFFF (hex) system memory addressing range. Configuring the DEC EtherWORKS LC/TP Board 2-7 Figure 2-2 Setting Memory Range C8000 to CFFFF for 32 KB 2-8 Configuring the DEC EtherWORKS LC/TP Board 2.5 I/O Address Selection (SW5) The DEC EtherWORKS LC/TP board uses one of two I/O address ranges (primary or secondary) to communicate with the CPU. Only one adapter in the computer can be set to use a given I/O address range. · Switch SW5 set to ON selects the primary I/O address range (300 - 30F; default setting). · Switch SW5 set to OFF selects the secondary I/O address range (200 - 20F) (Figure 2-3). Configuring the DEC EtherWORKS LC/TP Board 2-9 Figure 2-3 Switch Selecting 200 - 20F (hex) I/O Memory 2-10 Configuring the DEC EtherWORKS LC/TP Board 2.6 Remote Boot Selection (SW6) Switch SW6 determines whether the remote boot feature is enabled or disabled. 1 · Switch SW6 set to ON disables remote boot (default setting). · Switch SW6 set to OFF enables remote boot (Figure 2-4). Figure 2-4 Switch Enabling Remote Boot ------------------------------------------------------------ 1 This feature requires that the optional ROM chip be installed; refer to Appendix B for more information. Configuring the DEC EtherWORKS LC/TP Board 2-11 2.7 Remote Boot Period Selection (SW7) SW7 controls the timeout period for trying to enable a remote boot operation. · Switch SW7 set to OFF sets the remote boot timeout to 30 seconds (default setting). · Switch SW7 set to ON sets the remote boot timeout to 150 seconds (the longer remote boot timeout). Figure 2-5 Switch Selecting 150 Seconds for Remote Boot 2-12 Configuring the DEC EtherWORKS LC/TP Board 2.8 Interrupt Request Line Selection (SW8 - SW12) You can use switches SW8 through SW12 to select an interrupt request line (IRQ). The DEC EtherWORKS LC/TP board uses one IRQ line for the network interface (NI). Table 2-3 lists the switches and the interrupt request line enabled. Table 2-3 Interrupt Request Line Switches ------------------------------------------------------------ Switch Interrupt Request Line ------------------------------------------------------------ SW8 IRQ2 SW9 IRQ3 SW10 IRQ4 SW11 IRQ5 (default setting) SW12 IRQ7 ------------------------------------------------------------ Only one of the switches should be set to ON. By default, SW11 is set to ON, selecting IRQ5. Example: To select IRQ3, set SW9 to the ON position and set switches SW8, SW10, SW11, and SW12 to the OFF position (Figure 2-6). Configuring the DEC EtherWORKS LC/TP Board 2-13 Figure 2-6 Switch Selecting IRQ 3 3 Problem Solving ------------------------------------------------------------ This chapter describes problems you may encounter with the DEC EtherWORKS LC/TP board and suggests possible causes and solutions. 3.1 Fault Isolation By Symptom Table 3-1 describes how to isolate faults by the symptoms that are occurring.

The DETPR can be connected directly to either a workstation using local wiring, or it can be connected through building wiring using a cross-over cable. Figure D-1 shows a topology of these types of connections. ------------------------------------------------------------ 1 Designated to comply with IEEE 802.3 10BaseT standard for building wiring. Building Wiring Considerations D-3 Figure D-1 Connecting a DECrepeater 350 to a Workstation D-4 Building Wiring Considerations D.1.1 Cross-Over Connection A cross-over connection must be implemented in every Twisted- Pair link. The cross-over connection connects the transmitter on one media access unit (MAU) to the receiver of the MAU at the other end of the Twisted-Pair link. The cross-over connection may be implemented either internally in a repeater, or externally in a Twisted-Pair link. D.1.2 Implementation Any medium dependent interconnect (MDI) connector or cable that implements the cross-over function internally shall be marked with an "X." Figure D-2 depicts the connections and cables needed to connect the DETPR to either an H3350 or any 10BaseT workstation. The diagram also indicates where a cross-over must be used to maintain correct wiring. Figure D-2 DETPR--Digital-Only Wiring Building Wiring Considerations D-5 The DETPR has no embedded cross-over connection so it requires an external cross-over cable. To maintain a proper connection between the DETPR and either an H3350 or any 10BaseT workstation, a cross-over cable must be used. NOTE Some repeater products could include embedded cross-over wiring. D.2 DETPR to Workstation without Embedded Cross-over Wiring Connections D.2.1 External Cross-Over Wiring Schematic Figure D-3 is a detailed schematic of the pin-to-pin wiring. The building wiring is in accordance with prescribed standards and must follow appropriate pair and color code assignments. NOTE All connectors are not pin-to-pin. For a more detailed drawing of the DETPR wiring, refer to the Open DECconnect Building Wiring Components and Applications Catalog (PN EB-M4506-78). D-6 Building Wiring Considerations Figure D-3 DETPR--Digital-Only Wiring Cross-Over Wiring Schematic The connectors at the DETPR, patch panel, wall plate and workstation are all 8-pin modular jacks with the same pin assignments. NOTE The DETPR, H3350, and any 10BaseT workstations all have the same pin assignments. Building Wiring Considerations D-7 D.2.2 Connector Pinouts Table D-1 describes the connector pinouts and building wiring for the DETPR, H3350, and any 10BaseT stations.
