3.1.3 Replacing Power Supply Modules
User-Replaceable Power Supply Modules
While power supply modules are redundant, you should promptly replace failed
power supply modules to maintain network integrity and prevent data loss.
To replace a power supply module:
1. Disconnect the power source from the power supply module.
2. Remove the screws of the retainer plate (on some AC modules).
3. Move the Power Supply Release switch toward the right or unscrew captive
release screw.
4. Before grasping the power supply module by the silver handle, press the
release screw and then slide out of the chassis (Power supply modules are
hot-swappable).
5. Install a new power supply module. If module is equipped with an ON/OFF
switch install the module with the switch in the OFF position.
