Installation Instructions

Note:
The switch chassis can prevent an incorrect installation of a power supply. If you
insert a power supply upside down, it will not fully insert and the thumb screws
will not engage.
4. Once you install a power supply, you can proceed with connecting AC power.
Important:
You can hot swap power supplies while the switch is operational. One power supply is
required for continued switch operation. PoE+ load reductions can occur if you remove one
power supply while the switch is operating with dual power supplies.
