Troubleshooting the Power Subsystem

Check the following to help isolate a problem in the power subsystem. In the normally configured
SCE 1000 platform with redundant power supply units, it is unlikely that the device will not start at all.
However, at startup it should be verified that both power supply units are operational, and therefore the
following steps should be followed if one of the Power LEDs on the front panel remains unlit when the
SCE 1000 platform is powered up.
Note If the system powers off due to an environmental shutdown, wait at least one minute before manually
rebooting the system, or it will pause indefinitely.
