Caution
Make sure the AC power supply circuit is not overloaded. Use proper overcurrent protection,
such as a circuit breaker, to prevent overcurrent conditions.
An AC power cord is not included with the AC power supply. You can purchase AC power cords for use
in the US and Canada from Extreme Networks or from your local supplier. The cord must meet the
requirements listed in
Power Cord Requirements for AC-Powered Switches and AC Power Supplies
page 110.
Caution
A 150 W AC power supply cannot be installed and used in a switch that supports PoE, and the
600 W, 920 W, 1200 W, and 2000 W AC power supplies that support PoE cannot be installed
and used in a switch that does not support PoE.
Note
The switch operating system prevents PoE power contribution from a power supply that is
not listed for use with that particular switch model.
To install a 150 W, 600 W, 920 W, 1200 W, or 2000 W AC power supply in a switch, follow these steps:
1. If necessary, remove a blank panel from the back of the switch.
2. Verify that the power supply is right side up.
3. Verify that the power supply's airflow direction (front-to-back) is compatible with the switch.
4. Carefully slide the power supply all the way into the power supply bay, as shown in
.
Figure 51: Installing an AC Power Supply
5. Push the power supply in until the latch snaps into place.
Caution
Do not slam the power supply into the switch.
Note
If power supplies are not installed in both power supply bays, be sure to install a cover
over the unoccupied bay. Unoccupied bays must always be covered to maintain proper
system ventilation and EMI levels.
6. Connect the power cord to the power supply.
If the power supply is equipped with a power cord retainer, use the retainer to secure the power cord
to the power supply.
