! Safety WARNING ! (Cont.) To avoid personal injury or damage to equipment, do not install the module into a DEChub 900 or DEChub ONE unless the module is completely assembled, with the enclosure, bezel, and all faceplates in place. [Page 7.] VORSICHT Um den Benutzer vor Schaden zu bewahren und eine Beschädigung des Geräts zu vermeiden, muß das Modul erst vollständig mit Gehäuse, Blende und Anschlußdose montiert werden, bevor es in ein System DEChub 900 oder DEChub ONE eingebaut wird.
Introduction The DECserver 900GM is a network access server that supports up to 16 full modem control ports, or 32 eight–wire partial modem control ports. The DECserver 900GMx is identical to the DECserver 900GM, except that it supports up to 8 full modem control ports, or 16 eight–wire partial modem control ports. The ports may be used to connect asynchronous devices including terminals, printers, modems, or PCs to an Ethernet local area network (LAN).
Introduction (Cont.) Features Your DECserver 900GM and 900GMx modules include the following features: • Access to ThinWire 10base2 segment in the DEChub 900 MultiSwitch or in the DEChub ONE docking station. • Backplane access to multiple LANs through one of six flexible channels in the DEChub 900. • Automatic module self-test at powerup. • In-band Simple Network Management Protocol (SNMP) management.

Back Panel 1) Locking tab — Locks the module in the DEChub 900 backplane or in the DEChub ONE. It also contains the hot-swap switch lever. 2) 48-pin connector — Provides network and power connections to the module when the module is installed in a DEChub 900 or DEChub ONE. 3) Grounding bolt — Provides a chassis grounding connection between the module and a DEChub. 4) Manufacturing label — Lists the module’s part number, serial number, revision level, and power requirements.
Installing the Module The module hot-swap feature allows you to install the module into the DEChub 900 without turning off power to the DEChub 900. Seating the module initiates the powerup sequence if enough power is available. ! WARNING 1 To avoid personal injury or damage to equipment, do not install the module into a DEChub 900 or DEChub ONE unless the module is completely assembled, with the enclosure, bezel, and all faceplates in place.
Installing the Module (Cont.) 2 Seat the module into the DEChub 900 MultiSwitch. Release lever clicks when module is seated. Hub Manager status display a. Place the module’s mounting tab into a mounting slot on the DEChub 900. b. Pivot the module on the mounting tab and align the connectors. c. Firmly push the module onto the backplane connectors until the release lever clicks. d. Press down on the release lever to ensure that it is locked.
Installing the Module (Cont.) 4 Connect the port cables as required. Connect up to four 68-pin bulk connector cables. NOTE: All cables should have been installed, tested, and tagged at the site before you perform this installation. a. Insert the bulk connector plug into the port connector on the module. b. Using a flat-blade screwdriver, tighten the two screws at the ends of the plug.
Installing Flash RAM If you use a Flash RAM card for loading the operational software, perform the following: 1 Insert the Flash RAM card into the Flash RAM slot on the front of the module. a. The Digital label should be on the same side as the DECserver 900GM logo on the front panel of the module. b. When properly inserted, the Flash RAM card protrudes from the front panel about 1/4 inch. The Flash RAM card is keyed and cannot be inserted improperly.
Removing the Module 1 Disconnect all the cables from the module. a. To remove the bulk cables, use a flat-blade screwdriver to loosen the two screws at the ends of the plugs, then disconnect the cable. LKG–8761-93I 2 Unseat the module from the DEChub 900 MultiSwitch. Lift release lever a. Lift the release lever located on the top of the DEChub 900 mounting slot. b. Pivot the module back on its bottom mounting tab, and remove the module from the backplane.
LED Descriptions The module’s LEDs provide dynamic indications of its status. Table 1 shows the static states that are possible for each of the module’s LEDs. Table 1 12 Module LED States LED Name Off On Flashing Power No power to the module. Module receiving power. Faulty power connection or insufficient power. Module OK After approximately 2 minutes, module failed self test. Module passed self-test. Non-fatal self-test failure. Unit may still be operational.
Problem Solving Using the LEDs When diagnosing a problem with the module, note that the problem is often indicated by the combined states of the module’s LEDs. Table 2 lists the states of the LEDs for various error conditions that can occur during initial installation of the device, along with probable causes and steps you can take to correct the condition. Normal Powerup When power to the module is initially turned on, the following events occur: 1. The Power LED lights and remains lit.
Problem Solving Using the LEDs (Cont.) Table 2 Problem Solving Using the LEDs Symptom Probable Cause Corrective Action Power LED is off. The module is not receiving power. Ensure that the release lever (if installing into a DEChub 900) or the locking L-bracket screw (if installing into a DEChub ONE) is locked securely. If installing the module into a DEChub 900, check the power status on the Hub Manager status display.
Problem Solving Using the LEDs (Cont.) Table 2 (Cont.) Problem Solving Using the LEDs Symptom Probable Cause Corrective Action Module OK LED is off. Module does not have sufficient power. Ensure Power LED is on. Self-test is in progress. Wait up to 2 minutes for self-test to complete. Self-test failed. If the LED does not light after approximately 2 minutes, lift the release lever momentarily to repeat the self-test. If self-test fails again, replace the module. Non-fatal error.
