HP Fabric Clustering System Switch System Status
On the front of the HP Fabric Clustering System Switch are LEDs that indicate system, fan, and power
status.
System status LED is on the front left side of the switch, and is duplicated on the back of the switch on the
right side (facing the rear).
The system status LED indicates overall system health. It indicates the overall system status for power, fans,
temperature, and electronics. Check this LED first in the event of a suspected system fault.
The following command can be used on the switch to obtain System Status information from the CLI.

Power Supply Troubleshooting
Both power supply modules connect internally to the same power bus. If one power supply module fails, the
other immediately takes over. A power supply module may be hot-swapped without any disruption in power.
Check the status indicators of both power supply modules. Power Supply 1 is against the side of the switch,
and Power Supply 2 is between Power Supply and the Fan module.
Power supply status LEDs are on the front located in the middle of each power supply, and are visible through
the mesh of the bezel. If a power supply needs to be replaced, see “Replacing a Power Supply Module” on
page 124.
Table 6-2 Interpreting the System Status LEDs
Color Description
solid green System running with no detected errors.
blinking green (1/2sec. interval) System is initializing after application of
power or system reset.
slow blink, alternating
green/yellow (4 sec. interval)
LED test following application of power
(16 seconds).
solid yellow System error detected. Power, fans, or
electronics may be at fault.
off No system power or LED failure.
Table 6-3 Interpreting the Power Supply LEDs
color description
green (DC OK) On (green) indicates DC outputs from power supply within
regulated limits. Off indicates DC output out of location.
