Installation preparation

CAUTION:

• Hold power module by the bottom when moving it. Never attempt to lift a power module with its handle because the handle is not designed to support weight. Doing so might result in bodily injury or damage to the module.

• When inserting or removing a power module, verify that the switch is sturdy. To prevent bodily injury, avoid tipping the switch chassis.

• When hot-plugging power modules, make sure the insertion interval is no less than 30 seconds.
