Extreme Networks 1200 W DC PSU

Figure 14 shows the Extreme Networks 1200 W DC UL-listed accessory power supply unit (Model 60021/PS 2350). This power supply is compatible with the BlackDiamond 12804 switch. The power supply bay in the BlackDiamond 12804 switch can accommodate up to six hot-swappable Extreme Networks 1200 W DC PSUs. You cannot install a 1200 W DC PSU in the BlackDiamond 12802 switch.

In an N+N configuration, each group of power supplies can provide A/B feed redundancy for the system.

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 15). The connector end has a locking mechanism that locks onto the DC PSU to prevent accidental removal of the input DC cable.

Airflow enters from the front vents on the 1200 W DC PSU and exits to the rear vents of the switch. Airflow through the 1200 W DC PSU is independent of the airflow through the rest of the switch.

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