Extreme Networks 1200 W DC Power Supply
The Extreme Networks 1200 W DC UL-listed accessory power supply unit (Model number
60021/PS 2350) is compatible with the BlackDiamond 8800 series switches. The power supply bay in the
BlackDiamond 8800 series switch can accommodate up to six hot-swappable 1200 W DC power
supplies.
Figure 35 shows the 1200 W DC power supply.

Airflow enters from the front vents on the 1200 W DC power supply and exits to the rear vents of the
switch. Airflow through the 1200 W DC power supply is independent of the airflow that exists through
the rest of the switch.
The input DC cable has an input connector on one end and precut wire on the other end that goes to
the DC power source (see Figure 36). The connector end has a locking mechanism that locks onto the
DC power supply to prevent accidental removal of the input DC cable.

To use the 1200 W DC power supply, you need a -48 V DC power source capable of providing 50 A
dedicated power to each 1200 W DC power supply installed in the switch.
