Problem
indicator Component Possible cause Possible solutions
All green LEDs
are off
All CRUs Subsystem power is
off
Check that all expansion
enclosure power cables are
plugged in and the power
switches are on. If applicable,
check that the main circuit
breakers for the rack are
powered on.
AC power failure Check the main circuit breaker
and ac outlet.
Power supply failure Replace the power supply.
Midplane failure Contact an IBM technical support
representative to service the
expansion enclosure.

flashing
Drive CRUs Drive identity is in
process
No corrective action needed.

initialization process
(LIP) is being
generated in the
