Installing a Switch
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
AC-Powered Switches and AC Power Supplies
To install a 350 W, 715 W, 1100 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
Figure 23: Installing an AC Power Supply
5. Push the power supply in until the latch snaps into place.
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.
7. Connect the power cord to a grounded AC power outlet.
8. To install a second power supply, repeat the procedure.
23.
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.
Warning
Always make sure that the source outlet is properly grounded before
plugging the AC power cord into the AC power supply.
