1200-Watt DC-Input Power Supply Replacement Instructions 13
Checking the Installation
Note
When you turn ON power to the new power supply, the DC OK LED and the fan OK LED
will go on and stay on. No other LEDs should go on
This completes the power supply replacement procedure.
Proceed to the following section “Checking the Installation” to apply power and check the
installation.
Checking the Installation
To complete the installation, turn on the power supply and observe the LEDs on the power supply to
verify that the new supply is operating properly.
Step 1
Review the descriptions of the power supply LEDs on page 4.
Step 2
Check the following components to make sure they are secure:
•
Each power supply is inserted all the way into its bay, and the captive installation screw
is tightened.
•
At the DC power-source end of the power cable, the leads are securely attached to the
DC power, the source power is within the range indicated on the power supply.
•
When two supplies are present, the second cable is connected to a separate DC power
source if possible.
Warning
After wiring the DC power supply, remove the tape from the circuit breaker switch handle
and reinstate power by moving the handle of the circuit breaker to the ON position. (to see trans.ated
versions of this warning, refer to page 23.)
Step 3
Turn the power supply ON (|) by turning the switch clockwise one-quarter turn. The DC
OK LED and the fan OK LED will go on and stay on. No other LEDs should go on.
If the power supply switch resists, it is probably not fully inserted into the bay. Turn the
power switch fully counterclockwise to OFF (O), pull the power supply out of the bay about
two inches, then push the power supply firmly back into the slot. Do not slam the supply
into the slot; doing so can damage the connectors on the supply and the backplane. Tighten
the captive installation screw before proceeding.
