Installation preparation
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.
To prepare for installation:
Wear an ESD wrist strap and make sure it is correctly grounded.
Remove the blank panel (if any) from the slot to be used.
