3.5.2 Connecting an AUI Cable to an EPIM-X
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.
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.

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