Installation preparation

CAUTION:
Hold a power entry module (PEM) or power supply by the bottom when moving it. Never attempt to lift
•
a PEM or power supply 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 supply, verify that the switch is sturdy. To prevent bodily injury,
avoid tipping the switch chassis.
When hot-plugging power supplies, make sure the insertion interval is no less than 30 seconds.
