NOTE
The Extreme Networks 325 W DC PSU cannot be used in combination with any other Extreme Networks PSU.
The Extreme Networks 325 W DC PSU requires input DC cable Model 65025 (see Figure 18 ). 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.
This cable is shipped separately from the power supply unit. You must use this cable with the Extreme
Networks 325 W DC PSU.
Figure 18: Input DC Cable for the Extreme Networks 325 W DC PSU
Each Extreme Networks 325 W DC PSU must be powered by a 15 A dedicated power source that
delivers -40 to -72 VDC constant power to each 325 W DC PSU. Power distribution to the 325 W DC
PSU shall be provided using the Model # 65025 -48 V DC cable. Power to the 325 W DC PSU can be
from either a 15 A UL-approved overcurrent protection breaker or an SELV-approved power source in
accordance with IEC 60950-1 utilizing 15 A overcurrent protection.
Minimum Software Required
You must be running ExtremeWare XOS version 12.0 or later for the system to recognize the DC PSU.
