Recommended Action
This is not a fatal error. Turn off the power
once and then on again to restart the server. If
the error cannot be corrected, contact your
service representative.
1. Apply PIA appropriate to AC input voltage
and device configuration.
The server is configured to use 100 VAC
non-redundant power supply unit. If you
changed configuration, update PIA (see
"Power Supplies" in Chapter 2).
2. If the same error persists, contact your
service representative.
