Introduction 1­1 1 Introduction This Chapter outlines the general characteristics and functions of the MUXserver 90 Remote Terminal Server. It describes the versions available for different installation options. It provides a summary of the main features of the MUXserver in its various versions, with a listing of its labels, controls, indicators and connectors. Technical details of the MUXserver's requirements and performance are specified, and there is a brief outline of software requirements for MUXserver operations. An overview of a simple MUXserver network gives an example of a typical LAN configuration using the MUXserver 90 to provide remote links for asynchronous terminals via multiplexers and modems. A short description is also given of the kinds of management tools available for testing and trouble­shooting the unit's operations. 1.1 The MUXserver 90: an Overview of Features. The MUXserver 90 is a DEChub 90 module which operates as a Remote Terminal Server with multiplexing facilities. Connected to an Ethernet Local Area Network (LAN), it offers remote users access to LAN services via DECmux 300 multiplexers. It distributes its services via a single synchronous link at speeds of up to 64 kbps. The MUXserver 90 has the following features: · stand­alone or rack mountable in a DEChub 90 Ethernet backplane; · compact and easy to install; · can be installed in, and removed from, the DEChub 90 Ethernet backplane while the backplane is powered on; · suitable for both structured and unstructured wiring environments; · offers a console port for local management and trouble­shooting; and · enables network management through the Simple Network Management Protocol (SNMP) and Maintenance Operations Protocol (MOP) . 1­2 Introduction 1.2 The MUXserver Network The MUXserver Network connects remote terminals (or other asynchronous port devices) to an Ethernet Local Area Network (LAN). It consists of a MUXserver connected to the host computer system via an Ethernet LAN. From the single synchronous link of the MUXserver 90, a DECmux 300 multiplexer may be connected to another DECmux 300. In turn, that multiplexer may be similarly connected · in daisy­chain fashion · to a third multiplexer. A limit of 3 DECmux 300s in total may be serially linked to the MUXserver in this way. No changes are required to existing DECmux multiplexers to allow them to operate with the MUXserver 90. The MUXserver Network connects each remote terminal to the LAN with access to certain LAT services and INTERNET hosts offered by the LAN. The MUXserver Network Reference Manual gives full details of the features of the MUXserver Network. 1.2.1 Example of a MUXserver 90 Network Figure 1­1, on page 1­3 illustrates a basic MUXserver Network using the MUXserver 90. It shows: · one MUXserver 90 connected to a host via an Ethernet LAN, · a console terminal connected to the MUXserver 90's supervisor port, · a single synchronous link serviced by the MUXserver 90, and · three DECmux 300s connected, in daisy­chain fashion, to the synchronous link 1.2.2 Installation Installation options for the MUXserver 90 allow it either to be set up in stand­alone mode (for example, with desktop or wall­mounted positioning) or to be inserted into the DEChub 90 Ethernet backplane. The latter option allows the MUXserver 90 to work as a DEChub module, with power and communications connections directly onto the backplane. Stand­alone versions of the MUXserver 90 are linked to the LAN via ThinWire cabling from a 10BASE2 port. These versions all require a suitable DEChub 90 module power pack. Introduction 1­3 Figure 1­1 Example of MUXserver Network Connections 1­4 Introduction 1.2.3 Loadable Software The operating software for the MUXserver 90 is down­loaded to it from a load host" on the LAN when the MUXserver is first powered up. You can therefore update or re­configure the MUXserver's controlling program with relative ease · without the need for the installation of new firmware each time. (See MUXserver Software Installation Guide). A recessed Reset push­button gives the user the power to reset default values for important software variables at start­up time. The same button operates as a dump command during normal operations, initiating an up­line dumping of current program and data values from the MUXserver to the host for use by Digital in debugging and/or diagnostic checking. 1.2.4 Management and Diagnostic Options A console port on the MUXserver 90 enables direct connection of a terminal for management and diagnostic purposes. Firmware and operational software direct information and error messages via this output port. Light­emitting diodes (LEDs) on the MUXserver 90's front panel provide status information and help in management and trouble­shooting operations. 1.3 Controls, Indicators and Connectors 1.3.1 External Connectors External connectors on the MUXserver 90 include: · a 50­way D­type connector (front panel) which, with suitable adapters, can provide the following interfaces: ­ V.35 ­ V.24 ­ V.36 ­ V.10 ­ X.21 (leased circuit service) · a console port (front panel) providing a DEC­423 data­leads­only connection via a Modified Modular Jack (MMJ) connector for use with the console terminal. · the 10BASE2 ThinWire Ethernet connector (top of unit) for use in stand­alone mode. Introduction 1­5 · a DEChub 90 backplane connector (behind removable rear panel) which includes: ­ Power ­ Backplane Management serial line ­ Ethernet access · a power jack (rear panel) for connecting to a power pack in stand­alone mode. 1­6 Introduction Figure 1­2 Labels, Controls, Indicators and Connectors BlackBlackBlackBlackBlackBlackBlack1BlackBlackBlackBlack2BlackBlack3BlackBlackBlackBlack5BlackBlackBlack6BlackBlack4BlackBlackBlack7BlackBlackBlack8BlackBlackBlackBlackBlack10BlackBlack11BlackBlack12BlackBlackBlack9BlackBlackBlack12BlackBlackBlack13BlackBlackBlackBlackBlackBlackBlackBlackBlackBlack Introduction 1­7 Table 1­1 Description of Labels, Controls, Indicators and Connectors Key Item Description 1 Power Indicator Light turns on when power is supplied to the unit. 2 System OK Indicator Light turns on when the unit has successfully completed its diagnostics. 3 Network OK Indicator Light turns on when the unit is connected to a properly terminated network and software has been successfully down­line loaded. 4 Software OK Indicator Light flashes when software is operating. 5 Ethernet Address Label showing unique physical address of the unit 6 50­pin D­type Connector Connects a synchronous device to the MUXserver. The device connects to the port via an adapter cable and an extension cable. Refer to Appendix A, Connector Pins and Cables for information about these cables. 7 Console Port Connector (MMJ) Connects a terminal to the MUXserver 90 for performing diagnostic procedures and setting parameters. 8 Reset/Dump Push Button (recessed) If pressed while power is first applied, (for example, during initialisation operations or on installation into a DEChub 90 Ethernet backplane) this resets EEPROM­stored parameters to default values (see MUXserver Network Reference Manual). Otherwise, if pressed when the software is running, it initiates an up­line dump of the image of data and loadable software, directing the dump to the load host. 9 Network Connector (BNC) Connects the unit to the Ethernet LAN. Not used when the unit is installed in the DEChub 90 Ethernet backplane. 10 Backplane Connector Provides network and power connections to the MUXserver 90 when it is installed in the DEChub90 Ethernet backplane.

Retain this card for the present. When installation is successfully completed, the card should be forwarded to your system manager, who will also need to add further details (node name, server name, DECnet or INTERNET address etc.). Instructions contained in Appendix C must be observed when the MUXserver 90 product is being installed in the United Kingdom. Site Preparation and Verification 4­1 4 Site Preparation and Verification This Chapter describes the checks required to ensure that the selected installation site meets the MUXserver 90's physical, environmental, electrical and network cabling requirements, and that suitable equipment is available to complete the installation. 4.1 Installation Pre­conditions 4.1.1 Network Planned This manual does not detail the steps you need to take to establish the network associated with the MUXserver. Nor does it detail procedures for installing and testing inter­site synchronous links, synchronous modems and DECmux 300s. Relevant details for these procedures are given in the MUXserver Network Reference Manual and the MUXserver/DECmux 300 Network Installation Manual. 4.1.2 Software Installation for Self­Test Installation of the MUXserver software on any load host to be associated with the MUXserver is not a strict prerequisite for installation of the hardware. You can install the hardware in the absence of the software. Obviously, however, the MUXserver cannot operate properly if its software cannot be loaded. If you wish to observe the full operation of the power­on self test described in Chapter 6, (for example, after you have done an initial installation, and have attached serial devices to the MUXserver 90), you should ensure that the software has been installed on at least one load host.

To position the MUXserver 90 in an appropriate working environment, 2. To establish a LAN connection to it, and 3. To connect the MUXserver 90 to an appropriate power supply. To install the MUXserver 90 as a stand­alone unit, refer to Section 5.1. To install the MUXserver 90 in a DEChub 90 Ethernet backplane, refer to Section 5.2. 5.1 Stand­alone Configuration 5.1.1 Physical Positioning As a stand­alone unit, the MUXserver 90 can be placed on a table or desktop or mounted to a wall, using the back cover as a mounting base. Desktop Installation For desktop installation, lie the MUXserver 90 horizontally, with the Ethernet cable connection point on top. Wall Mounting For wall­mounting, remove the back cover of the unit and mount the unit as described below: To remove the back cover of the MUXserver 90, refer to Figure 5­1 below and take the the following steps: 1. Insert a small screwdriver into the top mounting hole in the cover, 2. Lift up on the internal latch which holds the cover in position, 3. While holding the latch up, pull the top of the cover away from the unit and down. Once you have removed the back cover, use the mounting holes on the cover as a template to locate the mounting screws. After marking for the mounting screws, mount the back cover to the wall, leaving 4 mms (approx. 5/32") clearance between screw head and the wall and then snap the unit into the back cover. 5­2 Positioning and Connecting Figure 5­1 Removing Back Cover Positioning and Connecting 5­3 5.1.2 LAN Connection Once your MUXserver 90 unit is placed or mounted, perform the following steps to connect it to the ThinWire Ethernet local area network: ThinWire Ethernet Connection 1. Attach the Ethernet T­connector to the BNC connector on the MUXserver 90, as shown in Figure 5­2 below. This shows the T­connector terminated using a 50­ohm terminator. Alternatives are: · the 50­ohm terminator is replaced by a cable if the MUXserver is not at the end of a cable segment; · the cable segment must be terminated by 50­ohm terminators at both ends unless a Digital Ethernet Multi­Port Repeater (DEMPR) or a Digital Ethernet Single Port Repeater (DESPR) is used; · where a cable segment is terminated in a DEMPR, a DESPR, or a DEChub 90 , the opposite end needs to have a 50­ohm terminator. 2. Turn the barrel of the connector clockwise to lock.

Figure 5­4 illustrates the same type of configuration, but using an international power supply. Refer to these figures when installing your MUXserver 90. Perform the following steps for power connection: 1. Plug the external power supply connector into the MUXserver 90's power connector. 2. Attach the power cord to the power supply (if you are using an international power supply, rather than the U.S. version). 3. Plug the power supply or power supply cord into a working AC outlet. 4. Switch on the AC outlet to apply power. Note that when power is applied, the MUXserver 90 immediately begins its self­test, which takes approximately one minute to complete. Refer to Chapter 6, The Power­On Self­Test, page 6­1, for information about running the self­test. Figure 5­3 Stand­alone Installation with Power Supply (for U.S., Canada, Japan) BlackBlackBlackBlackBlackBlackPower Supply Positioning and Connecting 5­5 Figure 5­4 Stand­alone Installation with International Power Supply 5.2 Backplane Installation If there is a cover on the back of the MUXserver 90, you must remove it before inserting the unit into the backplane (see Figure 5­1 on page 5­2, and accompanying instructions). Insert the MUXserver 90 into the DEChub 90 Ethernet Backplane this way: 1. Place the lower mounting tab, located on the back of the MUXserver 90 into a mounting slot on the backplane, as shown in Figure 5­5. Note that the MUXserver 90 can be installed in the DEChub 90 Ethernet backplane while the backplane is powered­up and connected to the network. A mounted MUXserver 90 can also be replaced with another (that is, hot­swapped) without having to power down the backplane. In each case, where power is applied to the backplane, the MUXserver 90 immediately begins its self­test, which takes approximately one minute to complete. Refer to Chapter 6, The Power­On Self­Test, page 6­1, for information about running the self­test. 2. Push in the top to rock the unit into place. An audible click is heard when the unit is securely latched into place.BlackBlackBlackBlackBlackBlackBlack 5­6 Positioning and Connecting Figure 5­5 MUXserver 90 Insertion in DEChub 90 Backplane Positioning and Connecting 5­7 To remove the MUXserver 90 from the DEChub 90 backplane: 1. Lift up the tab above the slot holding the MUXserver unit. 2. Pull the top of the unit forward, and when the top comes free from the slot, lift the bottom of the unit up and pull the whole unit outwards. The Power­On Self­Test 6­1 6 The Power­On Self­Test This chapter describes the MUXserver 90's initial self­test routine which is initiated automatically when power is applied to it. 6.1 Test Sequence Switching on power connected to the power cord, or inserting the MUXserver into an active DEChub 90 backplane causes the MUXserver to begin its self­test. The self­test consists of diagnostic routines that test and verify the operation of the unit. Pass/fail test results are indicated by the MUXserver's LEDs. The following sequence of events occurs: 1. As soon as power is applied to the unit, the green Power LED is lit. 2. The MUXserver 90 Hardware is tested to verify correct operation. The self­test takes approximately one minute. 3. Both the Software LED and the Network LED remain turned off if the self­test fails to complete. Results of the self­test are displayed by the unit's LEDs, as outlined in Table 6­1 below. 4. If it has successfully completed its self­test, the MUXserver attempts to down­line load the MUXserver 90 software image over the Ethernet LAN, from a suitably­configured load host. During this process, the Power LED and the System OK LED remain lit. 5. If the operational software is successfully loaded, the Network OK LED is lit, together with the Power and System OK LEDs. If the Software OK LED then flashes, the MUXserver 90 is fully operational, with software running. 6. If the software is not located, the Network OK LED, which has been off, starts to flash. 7. Flashing of the Network OK LED continues for a variable "time­out" period (see below). The LED then goes out and stays out for 30 seconds. 8. The MUXserver will make repeated attempts to locate the software, looping to Step 4. above. The duration of the "time­out" flashing period in Step 7. increases with each unsuccessful attempt, starting at 4 seconds, increasing to 8, 16, 32 seconds and so on  reaching as high as 300 seconds or so. 6­2 The Power­On Self­Test The following table summarises the states of the MUXserver 90 LEDs. Note that if hardware installation precedes installation of MUXserver software onto a the load host, normal operation does not commence. Table 6­1 States of the MUXserver 90 LEDs 6.2 Evaluating Test Results Upon completion of the self­test, examine the state of the MUXserver 90 LEDs to evaluate the test results. Successful Self­Test If the MUXserver 90 successfully completes the self­test to the stage where the Power and System OK LEDs remain lit, proceed to connect a device to the serial port, as described in Chapter 7, Connections to the MUXserver. Self­Test Failure If the MUXserver 90 fails its self­test (System OK LED Off after 60 seconds, or flashing): 1. Verify that the Ethernet is correctly connected and terminated. 2. Turn the MUXserver 90 off and then on again. If the self­test fails again, refer to Chapter 8, Trouble­shooting. Software Load Failure If the MUXserver 90 fails to load its software image, (longer and repeated Network OK LED flashing), verify that the software is correctly installed on the load host and is reachable from the MUXserver 90. (Refer to the relevant Software Installation Guide and the MUXserver Network Reference Manual.) Power System OK Network OK Software OK Meaning Off Off Off Off No power. On Off Off Off Internal Self test in progress. On Flashing Off Off Self test failed to complete. On On Off Off Internal Self test worked, attempting to load software.
