E-6
Possible Reasons
Power switch may not have been
pressed.
The system may not be connected
to AC power, or no AC power is
available.
A power supply problem may exist.
The power supply may not be
connected or inserted properly,
may have a damaged connector, or
may have failed.
The power supply backplane may
need to be replaced.
A system interconnect problem may
exist. The system power LED is
illuminated amber.
The Next Step
Press the power switch.
If the server does not start, further
information is needed.
Verify the power supply LEDs
•
Off—no AC power
•
Blinking green—AC power present,
system has auxiliary power.
•
Solid green—system power is on
•
Solid amber—power supply fault.
Either system power is not hot-plug
redundant due to the AC
connection or a fault is detected in
the power supply.
Further info is needed. Go to Question 2
in Table E-1.
If your power supply starts, and you can
verify operation of the power supply and
system fans, then you may assume that
the following is true:
•
AC power is connected to the
power supply and providing
adequate power.
•
No system interconnect problem
exists.
