Task 1: Compare the Power Ratings Task 1: Compare the Power Ratings Compare the module’s power ratings (1) with the values shown in the Hub Manager Status display (2) (see Figure 2-3). If the power values on the module’s manufacturing label do not exceed the values shown in the Hub Manager status display, go to Task 2.
Task 2: Seat the Module into the DEChub 900 Task 2: Seat the Module into the DEChub 900 To seat the module, perform the following steps (refer to Figure 2-4). Step Action Place the module’s mounting tab into a mounting slot (1) on the DEChub 900.
After the module completes self-test, the Module OK LED lights and remains lit. Then the Hub Manager status display shows: Slot <slot-number> DECswitch 900EF up. NOTE Refer to Appendix A, Problem Solving if the LEDs do not operate as described.
Task 4: Connect the Cables Task 4: Connect the Cables Depending on your network configuration requirements, connect the appropriate FDDI cables, AUI cables, and UTP/STP cables. See your network manager if you are not sure which cables to connect. NOTE All cables should be installed, tested, and tagged at the site, prior to this installation.
Task 4: Connect the Cables Task 4 (Cont.): Connect the FDDI Cable To connect the FDDI cable, complete the following steps (see Figure 2-5). Step Action Remove the protective caps from the module’s FDDI connector and from the FDDI cable plug. Align the keyway on the FDDI cable plug with the key on the module’s FDDI connector.
Task 4: Connect the Cables Task 4 (Cont.): Connect the AUI Cable To connect the AUI cable, complete the following steps (see Figure 2-6). Step Action Remove the loopback plug (if present) from the module’s AUI connector and from the AUI cable plug. Push the module’s AUI connector slide latch up (1) to the unlocked position.
Task 4: Connect the Cables Task 4 (Cont.): Connecting the UTP/STP Cable The DECswitch 900EF Router module uses straight-through 10BaseT (8-pin MJ) port connectors. Select the appropriate UTP/STP cable type (crossover or straight-through) to ensure that the module’s transmit/receive signals connect correctly to the transmitter/receiver of the connected device.
Task 4: Connect the Cables To connect the UTP/STP cables, complete the following steps (see Figure 2-7). Step Action Align the release tab on the cable plug (1) with the keyway on the module’s 10BaseT port connector. Insert the plug into the connector (2), ensuring that the release tab snaps into the locked position.
