CAUTION:
Follow the forward inertia of the power supply when inserting it into the chassis, and make sure the

To prevent damage to the connectors inside the switch chassis, insert the power supply gently. If you

encounter a hard resistance while inserting the power supply, pull out the power supply and insert it
again.
• If only one power supply is installed, install a power filler module in the empty power supply slot for
good ventilation of the switch.

power supply slowly along the guide rails into the slot.

rather than use excessive force to push it in.
