LED Marking and Identification
The power supply uses a bi-color LED: Amber and Green. Below are table showing the LED
states for each power supply operating state and the LED’s wavelength characteristics.
Refer to the

Power Supply Condition
LED State
Output ON and OK.
GREEN
No AC power to all power supplies.
OFF
AC present/Only 12VSB on (PS off) or PS in Cold
redundant state.
1Hz Blink GREEN
AC cord unplugged or AC power lost; with a second
power supply in parallel still with AC input power.
AMBER
Power supply warning events where the power supply
continues to operate; high temp, high power, high
current, slow fan.
1Hz Blink Amber
Power supply critical event causing a shutdown; failure,
OCP, OVP, Fan Fail.
AMBER
Power supply FW updating.
2Hz Blink GREEN

Temperature Requirements
The power supply operates within all specified limits over the T
op
temperature range. All
airflow passes through the power supply and not over the exterior surfaces of the power
supply.
