CONNECTING TO THE NETWORK

5.Check that the PWR LED on the EPIM-A is on. If the LED is not on, contact Cabletron Systems Technical Support.

6.If the PWR LED is on with the AUI cable disconnected, continue with the following checks:

a.Check the AUI connections for proper pinouts. The pinouts for the transceiver connection are listed in Chapter 2.

b.Check the cable for continuity.

c.Reconnect the AUI cable to the SEHI and the device.

If the LED is still not on after reconnecting the segment, contact Cabletron Systems Technical Support.

4.1.7Connecting an AUI Cable to an EPIM-X

Caution: The signal quality error (SQE) switch remains in the OFF position for most network connections. However, some Data Terminal Equipment (DTE) requires SQE. Refer to your DTE manual for SQE requirement information.

To connect an EPIM-X to a device not requiring SQE:

1.Check that the SQE LED on the EPIM-X is off. If the SQE LED is on, check the position of the SQE switch.

Note: If the SQE light remains on, even though the SQE switch is in the OFF position, contact Cabletron Technical Support.

2.Attach one end of an AUI cable, no longer than 50 meters in length, to the port located on the EPIM-X (Figure 4-7) and the other end to the intended node.
