Extreme Networks Extreme 7520 Series - Install an 800 W Internal AC Power Supply

All installed power supplies must have the same airow direction (front-to-back or
back-to-front) and must match the airow direction of the installed fan modules.
Warning
To prevent an electrical hazard, make sure that the AC power cord is not
connected to the power supply before you install the power supply in the
power supply bay.
Warning
Make sure that the AC power supply circuit is not overloaded. Use proper
over-current protection, such as a circuit-breaker, to prevent over-current
conditions.
1. If necessary, remove a blank panel from the back of the switch.
2. Verify that the new power supply is right side up.
3. Verify that the new power supply's airow direction (front-to-back or back-to-front) is
compatible with the other installed power supply (if any) and with the installed fan
modules.
4. Carefully slide the power supply all the way into the power supply bay (see Figure
28).
