LED responses at startup
Power supply LEDs
About this section
This section describes the LED responses for the AC or DC power supplies in your F800 series filer. For each of the following, the location of the LEDs is identified and the LED functionality is described:
AC power supply LEDs
Location of LEDs
The following illustration shows the AC power supply LEDs on the back panel.
Description of LEDs
The following table describes the AC power supply LEDs.

Explanation
|
|---|
Amber
|
On
|
Power supply is receiving AC power.
|
Off
|
AC power is not present.
|
Green
|
On
|
Power supply output is good.
|
Off
|
Power supply output is bad.

DC power supply LEDs
Location of LEDs
The following illustration shows the DC power supply LEDs on the back panel.
Description of LEDs
The following table describes the DC power supply LEDs.
LED
|
State
|
Indicates
|
|---|
Amber
|
On
|
Input voltage from the DC power source is good; that is, it meets specifications.
|
Off
|
Input voltage from the DC power source does not meet specifications (-40V DC to -60V DC).
Check the input voltage with a voltmeter. If the voltage does not meet specifications, correct it. If it does, the power supply is the source of the problem. Replace the power supply.
|
Green
|
On
|
Output voltages from the power supply to the filer are good; that is, they meet specifications.
|
Off
|
A problem exists with the power supply or filer.
First try changing the power supply. If the green LED still does not illuminate, the filer could be bad (for example, shorted or overloading the power supply).
