Hot-Swap Power Supply Removal
Before performing this procedure, read the following “Safety Notices” on page xi.
If you are servicing a system that has two power supplies installed, you can replace
each power supply (one at a time) without shutting down the system.
To remove a hot-swap power supply, do the following:
Note: You do not need to turn off the power to the system to install hot-swap power
supplies.
1. On a Model 6C4, open the front and rear rack doors and place the system into the
service position as described in “Placing the Model 6C4 into the Service Position”
on page 355.
On a Model 6E4, open the bezel door.
2. Visually check the power supply LEDs. If the amber LED is lit, suspect that power
supply to be faulty.
3. Remove the service access cover as described in “Service Access Cover Removal
(Model 6C4)” on page 357 or “Service Access Cover Removal (Model 6E4)” on
page 363.
4. Remove the power cable from the rear of the faulty power supply.
5. Wait at least 10 seconds before performing the next step.
6. Grasp the ends of both power supply handles, and slide the retractable
spring-activated portion of each handle toward its hinged base. This action
releases the locking tab located on the bottom side of each release handle. See
