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.
