Cabletron Systems NBR-420 사용자 설명서

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.

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