10. Press the two latches near the edges of the supply outward to lock the supply in place.
11. If necessary, replace the power supply locking screw.
12. After the power supply is properly inserted, connect the power source to the wires to activate the circuit.
Verifying Proper Operation
To verify the proper operation of the power supply after power on, you can observe the LEDs on the power supply.
After the FastIron device powers on, you can observe the LEDs on the front of the device to verify that it initialized
successfully. Table 6.2 outlines the LEDs, the desired state of each LED, possible abnormal states of each LED,
and what to do if an LED indicates an abnormal state.
Table 6.2 lists the LEDs that show power status. The power supplies themselves do not have LEDs.
The software regularly polls the hardware for power status information. You can display the status information
from any management session. In addition, the software automatically generates a Syslog message and SNMP
trap if a status change occurs.
Displaying the Status of the Power Supplies
You can display the status of the power supplies by entering the
show chassis
command at any level of the CLI.
The display shows whether a power supply is installed in the specified power supply slot and the status of the
power supply, which can be one of the following:
•
OK – The power supply is functioning properly and supplying power to the chassis and installed modules.
•
Failed – The power supply is not functioning and is not supplying power to the chassis and installed modules.

Power
ON – Green
(steady)
The device is powered on
and has enough power to
operate.
OFF
The device is not powered on, or
has been powered on but does
not have sufficient power to
operate.
PS1
ON – Green
(steady)
Power supply 1 is installed
and is functioning normally.
Power supply 1 is located in
the right-hand bay (when you
are facing the rear of the
device).
OFF
Power supply 1 is not installed or
is not providing power.
PS2
ON – Green
(steady)
Power supply 2 is installed
and is functioning normally.
Power supply 2 is located in
the left-hand bay (when you
are facing the rear of the
device).
OFF
Power supply 2 is not installed or
is not providing power.
