• Before installing/removing the PSU, turn off the server and all peripheral
devices. Also unplug all power cables from the server ( "1.4.3 Turning Off the
Server" (p.32)). Failure to do so may cause electric shock.
However, when the redundant power function is supported, a defective PSU
can be replaced without shutting down the server.
• Do not insert your hands in the PSU slot when removing the PSU. Doing so
may cause electric shock.
• The PSU is heavy, so handle it carefully.
If you drop it by mistake, injuries may result.
