CORRECTIVE ACTION
If you connect a Microlight DSU cabinet to
the 3300 ICP via Triple FIM circuits 2 and
3, you must ensure that the Microlight
Peripheral Cabinet is connected to Triple
FIM circuit 1. Triple FIM circuit 1 provides
the clock source for all Triple FIM circuits.
Without circuit 1, there is no clock source
for other FIM circuits (2 and 3), resulting in
the internal DSU not working.
Also ensure that the Control Resource
Card (CRC) has not been removed from
the MicroLight cabinet.
Fix connections or replace cabling.
Fix connections.
Replace cable or straighten pins on

Administration Tool online help.
Replace Interface Assembly.
Replace card.
Check the Dial-Up Networking connection
settings.
