To replace a Summit X850 W AC power supply:
1 Disconnect the AC power cord from the wall outlet and from the power supply.
2 Note the orientation of the installed power supply, and the location of the latching tab at the right of
the unit.

4 Carefully slide the power supply the rest of the way out of the switch.
Caution
Power supplies may become very hot during operation. Wear thermal protective gloves
when you remove a power supply from an operating switch.
Note
If you are not installing a replacement power supply, install a cover over the unoccupied
power supply bay. Unoccupied bays must always be covered to maintain proper system
ventilation and EMI levels.
5 Verify that the replacement power supply is oriented the same way as the unit you removed.
6 Carefully slide the power supply all the way into the power supply bay (see the figure below).
