4.6.2 DC Power Supply Module

This section describes the appearance, functions and the technical parameters of the DC power
supply module.
The PEM of the E8000E-X3 is 1 U high, as shown in
Issue 01 (2012-11-07)
a. The width does not include the width of the mounting ear attached.
b. The measurement point of the temperature and humidity is 1.5 m over the floor and 0.4 m in front of
the cabinet without the front and back doors.
c. Short-term operation means that continuous operating time does not exceed 48 hours and accumulated
operating time per year does not exceed 15 days. If an operation exceeds either of these conditions, it is
called a long-term operation.
The power supply system consists of two AC power modules or two DC power modules
working in 1+1 backup mode.
Both AC power modules and DC power modules support alarm functions. DC power
