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 SEH and the device.
If the LED is still not on after reconnecting the segment, contact
Cabletron Systems Technical Support.
4.1.6 Connecting an AUI Cable to an EPIM-X
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.
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.
!
CAUTION
If the SQE light remains on, even though the SQE switch is in
the OFF position, contact Cabletron Technical Support.
