2.6 Power Supply System

This chapter describes the power supply system used by the E8000E-X16.
2.6.1 Features and Distributed Architecture of the Power Supply
System
This section describes the features, distributed architecture, and the PEM of the power supply
system.
If DC power source is used, connect the DC power cables to the PEM input terminals.
If AC power source is used, use two suitable external AC-DC convertors. The number of rectifier
modules of the AC-DC convertors depends on the system power consumption. The AC-DC
convertors converts AC power to DC power and supply DC power to the PEMs.
As shown in
having two power inputs. These eight power inputs work in backup mode.

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 the back doors.
c . Short-term operation means that the continuous operation time does not exceed 48 hours and the
accumulated operation time per year does not exceed 15 days. Otherwise, it is called long-term operation.
