Power Supplies
DANGER
Do not attempt to open the covers of the power supply. Power supplies are
not serviceable and are to be replaced as a unit.
D02
This system drawer has power supplies that have hot-swap capabilities. To use this
feature, you
must have two power supplies in place.
Non-Hot-Swap Power Supply Removal
If you are servicing a system that has only one power supply installed, you must follow
the non-hot-swap power supply removal procedure. Systems that were configured with
one power supply at the factory have a power supply filler panel. The filler panel
protects the vacant power supply connector from dust or damage.
Before performing any of the following procedure, read and understand all of the safety
notices beginning with “Safety Notices” on page xi.
To remove a non-hot-swap power supply, do the following:
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. Shut down the system as described in “Stopping the System” on page 350.
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 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 the following
