Powering On the Chassis
Follow these steps to turn on chassis power:
Procedure
Step 1
Power on the circuit breaker to your power sources one at a time.
Step 2
Verify that the correct Power Input LED on each power module in the tray is lit (one input on the LED flashes
and both inputs on the LED are solid). Continue with steps 1 and 2 until all inputs have been verified.
On the DC power tray, the Power Input LED is lit solid green if both DC feeds are valid and blinks
green if only a single DC feed is valid.
Note
Step 3
Set the power tray switch for Feed A to the ON (1) position. This powers on slots PWR MOD 0 through PWR
MOD 3.
Step 4
Verify that the Power Output LED on each power module in the tray is lit.
Step 5
Repeat Step 3 and Step 4 for Feed B.
