B slot. The following procedure shows how to install it in
the PWR B slot. Follow the same installation process to
install a DC power supply in the PWR A slot.
2. Locate the power cord retaining clip.
3. Locate the retaining bracket on each side of the AC power
connector on the back of the power supply.
