Extreme Networks 1200 W DC PSU

Minimum Software Required

You must be running ExtremeWare XOS version 11.3 or later for the system to recognize the DC PSU.

Pre-Installation Requirements

You need the following tools and equipment to install or remove a 1200 W DC PSU:

●ESD-preventive wrist strap

●Input DC power cable (provided with the DC PSU)

●-48 V DC power source capable of providing 50 A dedicated power to each of the 1200 W DC PSUs installed in the switch

●Thermal protective gloves (required for removal)

Installing the DC Wiring

The input DC cable for the DC PSU is supplied with the 1200 W DC PSU (see Figure 40); you must use this cable with the DC PSU.

Each 1200 W DC PSU must be powered by a 50 A dedicated power source that delivers -40 to -72 VDC of constant power. The source should be a Common Bond Network (CBN) according to GR-1089. Power distribution to the 1200 W DC PSU shall be provided using the -48 VDC harness provided. Power to the 1200 W DC PSU can be from either a 50 A UL-approved overcurrent protection breaker or an SELV- approved power source in accordance with IEC 60950-1 utilizing 50 A overcurrent protection.

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

If necessary, use appropriate termination lugs for 8 AWG (10 mm2) copper-stranded wire on cable ends of the cable to connect to the DC power source.

The blue termination (-48 V) connects to a 50 A overcurrent protection circuit device, and the black (return) termination connects directly to the RTN bus of the DC power source. The green/yellow termination (ground) must connect to the same earth ground point as the switch.
