Connecting the SEHI to the Network

5.1.6Connecting an AUI Cable to an EPIM-X

The Signal Quality Error (SQE) switch remains in the OFF

!position for most network connections. However, some Data

C AUT IO N Terminal Equipment (DTE) requires SQE. Refer to a DTE manual for SQE requirement information.

Perform the following steps 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 Systems Technical Support.

2.Attach one end of an AUI cable of up to 50 meters in length to the port located on the EPIM-X (Figure 5-6) and connect the other end to the intended node.
