Safety Precautions

Always follow these safety precautions to avoid injury and damage to the enclosure.

Electrical Safety Precautions

Always follow electrical safety precautions to avoid injury and damage to the enclosure.
Warning: Disconnect power from the enclosure when removing or installing
components that are not hot-swappable. When disconnecting power, first power
down the controller(s) and enclosure(s) using the Storage Center System Manager
and then unplug the power cords from all the power supply/cooling fan modules in
the enclosure.
• Know the locations of the equipment power switches and the room's emergency power-
off switch, disconnection switch, or electrical outlet.
• Do not work alone when working with high voltage components.
• Do not use mats designed to decrease electrostatic discharge as protection from
electrical shock. Instead, use rubber mats that have been specifically designed as
electrical insulators.
