5. Check that the PWR LED on the EPIM-A is on. If the LED is not
on, 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 SEHI and the device.
If the LED is still not on after reconnecting the segment, contact
Cabletron Systems Technical Support.
4.1.7 Connecting an AUI Cable to an EPIM-X
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.
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 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 4-7) and the other end to
the intended node.
