System Does Not Appear to Be Powered On
System Does Not Appear to Be Powered On
1. If the fans are not turning and if none of the green LEDs on the system
components in an enclosure are lit, the power might not have been properly
applied. Check that the AC power cords and the power-on cables are properly
connected and repeat the power-on procedure.
2. If AC power is being supplied to the system but the system still does not appear to
be powered on, the system might be running internal power-on self-tests (POSTs).
Wait several minutes. It can take as long as 10 minutes for the POSTs to finish.
3. If the system still does not appear to be powered on after this time and you cannot
determine the cause of the problem, contact your service provider.
Power Is Applied to Enclosure But Fans Are Not Turning
1. If a green LED is not lit on one or more system enclosures:
a. Ensure that all AC power cords and power-on cables are properly connected.
b. Repeat the power-on procedure.
2. If the AC power cords and power-on cables are properly connected and the server
still is not powered on:
a. Locate the power-on push button on the PMF CRU.
Caution. If the system is powered on, green LEDs are lit on enclosures, and fans are not
turning in one or more enclosures, power off the system immediately to avoid potential
hardware damage. Then contact your service provider.
