Replace a 2000 W AC Power Supply
To replace a 2000 W AC power supply, follow these steps:
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 left of
the unit.
3. Push the latching tab toward the power supply handle and pull outward on the handle to disengage
the power supply internal connectors. See
Figure 48: Removing an ExtremeSwitching 2000 W AC Power Supply
4. Carefully slide the power supply the rest of the way out of the switch.
5. Verify that the replacement power supply is oriented the same way as the unit you removed, and has
the same airflow direction.
6. Carefully slide the power supply all the way into the power supply bay, as shown in

Caution
Power supplies can 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.
