Replace Chassis Components
Remove a DC Power Supply Unit
When removing a DC Power Supply Unit (PSU), you will need access to the terminal block of the module to
disconnect the DC-input wires. If the front panel of the chassis has limited access because of other interfering
cables, consider removing the module from the chassis before disconnecting the DC-input wires. If you do
have clear access to the terminal block, you can disconnect the DC-input wires and then remove the module
from the chassis. In either case (whether you have access to the front panel or not), you must begin by
completing all the steps described in
depending on your setup.
The procedures to disconnect DC-input wires and to remove the module from the chassis have been described
in
