Verifying Proper Operation
To verify the proper operation of the power supply after power on, you can observe the LEDs on the power supply.
Table 7.1 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.
If a problem persists after taking action described in this table, contact Foundry’s technical support.
Table 7.1: Desired and Abnormal Power Supply LED States After System Power On
LED
Desired State
Desired State
Meaning
Abnormal
State
Abnormal State Meaning/Action
AC OK
(AC
supply
only)
ON – Green
(steady)
The power supply is
receiving AC power
from an AC power
source
OFF
The power supply is not receiving
power from an AC power source. You
can do the following:
•
Make sure that the power supply
cord is connected securely to the
wall outlet and the power supply.
•
Make sure that the wall outlet is
rated for 115/120V and 20A. If it is
not, obtain a cable that is
compatibly rated for the outlet.
•
Make sure that the wall outlet has
power.
DC IN
(DC
supply
only)
Green (steady)
The power supply is
receiving DC power
from a DC power
source
OFF
The power supply is not receiving
power from a DC power source. You
can do the following:
•
Make sure that the power supply
cables are connected securely to
the power source and the power
supply.
•
Make sure that the DC power
source is 48VDC @ 37.0 A.
•
Make sure that the power source
has power.
DC
OUT
ON – Green
(steady)
The power supply is
supplying DC output
power to the chassis
OFF
The power supply is not supplying DC
output power to the chassis.
If this occurs and the AC OK (AC power
supply) or DC IN (DC power supply)
LED is Green, then there is a problem
with the power supply and it must be
replaced.
ALM
OFF
No alarms present and
the power supply is in
normal operating
condition.
Amber
There is an alarm present and the
power supply is malfunctioning.
Verify the AC or DC input and DC
output voltages.
