Symptoms and Solutions
The OVER SPEC LED on the
Light Path Diagnostics panel
is lit, and the power channel C
LED on the system board is lit.
1.
Remove the DIMMs and the ServerRAID SAS controller, and
restart the device. If the OVER SPEC and power channel LEDs
are still lit, do the following:
a.
Check the hot-swap power supplies, replacing them one at a
time. Restart the device each time that you reinstall a power
supply.
b.
Check the power backplane.
c.
Check the system board.
2.
Restart the device. If the OVER SPEC and power channel LEDs
are off, reinstall the DIMMs, one pair at a time. Restart the device
each time that you reinstall a DIMM. If the power channel C LED
is lit, the pair of DIMMs that you just reinstalled is defective.
Replace the defective DIMMs.
3.
Reinstall the ServeRAID SAS controller and restart the device. If
the OVER SPEC and power channel LEDs are off, replace the
ServeRAID SAS controller.

PCI slots 3 and 4, and the adapters on the PCI riser card in PCI
slots 1 and 2). If the OVER SPEC and power channel LEDs are
still lit, do the following:
a.
Check the hot-swap power supplies, replacing them one at a
time. Restart the device each time that you reinstall a power
supply.
b.
Check the power backplane.
c.
Check the system board.
