NDICATIONS
This section describes the normal LED indications that you should see when the
system starts up.
At startup, the normal system monitor LED indications are as follows:
The POWER LED indicator lights green and remains green.
The ALARM, FAN and TEMP LED indicators flash twice,
alternating between red and green. When the platform initialization is

The rear panel of the SCOPIA 400 chassis contains dual power supply units,
each with a power switch, an AC mains power connector and a safety fuse. The
two PSUs use current sharing to provide redundancy—if one PSU fails, the
second PSU can handle the operational load of the chassis until the failed unit is
replaced. The PSUs are located to the left of the chassis rear panel., as shown in
Figure 1-2 .
Each power supply has one LED indicator—green to indicate normal operation,
red to indicate a malfunction.
In normal operation, both PSUs display a lit green LED, and the front panel
system monitoring POWER LED lights green.
Note To enable PSU redundancy, connect both power inlets to a power source.
If you connect only one power cable, the POWER LED on the chassis front panel
and the LED indicator on the PSU not in use will both light red.
