Chapter 12. Power problems
No power to multiple devices
1.
Check that the 30 amp twist lock plugs are locked into the customer supplied
receptacles.
2.
Check the main power breakers at the customer breaker panel and ensure they
are on.
3.
Measure the voltage on the power out side of the Frame Power Block. If no
voltage is present have the customer’s electrician check for power issues. If no
problems are found with the customer’s power then replace the Input Power
Block (FRU 32P1077). If the correct voltage is present, continue with the next
step.
4.
Verify the PDU breakers are in the ON position.
5.
Verify the PDU plugs are securely seated into the Power Out sockets on the
Frame Power Blocks.
6.
Verify voltage at the Power Out ports on the PDU using a Multimeter. If no
power is present replace the PDU (FRU 9N9671). Otherwise, continue with the
next step.
7.
Swap out the power cable on the failing unit. If power LEDs do not appear on
the failing unit, replace the power supply or complete unit if the power supply
cannot be replaced.
No power to an individual device
1.
Verify the PDU plugs are securely seated into the Power Out sockets on the
Frame Power Blocks.
2.
Verify voltage at the Power Out ports on the PDU using a Multimeter. If no
power is present replace the PDU (FRU 9N9671). Otherwise, continue with the
next step.
3.
Swap out the power cable on the failing unit. If power LEDs do not appear on
the failing unit, replace the power supply or complete unit if the power supply
cannot be replaced.
