!

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.

Connect an EPIM-X to a device not requiring SQE as follows:

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, no longer than 50 meters in length, to the port located on the EPIM-X (Figure 3-14) and the other end to the intended node.
