Before you continue with the power-supply removal and installation procedure,
review the following information.
Notes:
1. During normal operation, both hot-swap power-supply bays must have power
supplies installed for redundancy.
2. Two cable-restraint brackets are on the rear of the tower model servers. After
you install the hot-swap power-supply option and connect the cables to the
selected devices, you can use these cable-restraint brackets to manage the
cable routing. Route the power cords through the power-cord restraint bracket
on the bottom. Route the remaining cables (for example, the cables that are
connected to the I/O ports) through the I/O cable-restraint bracket on the top.
If you install or remove a power supply, observe the following precautions.
