LED State Power Supply Condition
Off No AC power applied to the power supply.
Green Power supply on and healthy.
Amber Power supply is on but experiencing a critical event causing a
shutdown. Examples that can cause a shutdown include:
• Fan failure
• Over-voltage protection (OVP)
• Over-current protection (OCP)
In a 1+1 configuration where both power supplies are
plugged in but AC has been removed from one power supply,
the LED signal will still operate with the redundant power
supply in parallel and will, thus, be lit amber.
To bring a power supply back into full service after correcting
an error condition, remove and then re-apply AC power. This
can be as simple as unplugging the power supply and then
plugging it back in.
Blinking amber Power supply is on and continuing to operate but
experiencing a warning condition (for example: high
temperature, high power, high current, slow fan).
The warning condition will transition to a failure and the power
supply will shut down. If you have any concerns, replace the
power supply using the instructions in the section,
Replacing
a Power Supply, on page A-11 .
