To remove and replace an AC power supply, use the following procedure.
Caution
You cannot mix power supply types within the chassis. If you plan to replace a
2000 W power supply from an original system with a newer, 2500 W power
supply, you must replace all of the power supplies and the power shelf (see
Table 7-1 on page 7-30
). You must shut down the router to perform the upgrade.
Be sure to notify the appropriate personnel that all routing traffic will stop while
the upgrade takes place.
Step 1
Unplug the power supply cord from its AC outlet.
Step 2
Power off the circuit breaker assigned to that AC outlet.
Warning
To ensure that power remains off while you are performing this procedure, tape
the circuit breaker switch in the off (0) position.
Step 3
Remove the power supply from the power shelf.
