Major Service
Affecting
Cell bus hard failure. Each of these alarms indicate a
switch fabric failure. Check
alarm messages, is the failure
on both buses? One card? All
cards? If single card failure,
remove from backplane, check
pins in backplane connector,
and reseat. One card failure
could pull down the entire bus.
Pull each card out one at a time
starting with protect, check the
pins in the backplane connector,
monitor system traffic for
recovery, then reseat the card.
Perform switch over via GUI or
craft interfaces before pulling
EIMs if necessary. Do not pull
the working cards. Repeat
procedure for SC TEIM in slot
18 at the rear of the shelf. This
is a bus termination and the
system will crash without it.
