Removing the PSU Keying Bracket
Use this procedure to remove the PSU Keying bracket.
Before you begin
The chassis must be completely removed from the rack to provide access to the exterior of the chassis where
the PSU Keying bracket will be installed.
When the chassis is removed from the rack, make sure that you place the chassis on an ESD-safe workspace,
for example, a rubberized mat.
Step 1 If you have not already removed the chassis from the rack, do so now.
Go to Removing the Chassis from a Rack, on page 55 .
Make sure to follow all safety requirements while uninstalling the chassis, including using a device, such as a
mechanical lift, to bear the weight of the chassis.
Caution
Step 2 With the chassis in an ESD-safe work area, locate the PSU Keying bracket on the right exterior side of the chassis.
