1.4.4Power Distribution Box
There is a dedicated AC distribution box or DC distribution box in the lower section of ES4710BD backplane, distributing power supply for the corresponding AC or DC power module. A grounding post is provided on the chassis on both sides of the distribution box for switch grounding. There is also an extraction handle, which is intended for the installation and removal of the distribution box
only. Never lift or move the switch with this handle!
Enterprise network users usually require equipment to have 220 VAC input, the AC power modules and AC distribution box can satisfy this application. Three 220V/110 VAC power input sockets are provided on the panel of the ES4710BD AC distribution box. Input AC power will first pass through protective circuits, such as the AC filter, lightning protection tube, and then provide power for the three AC power modules. The other modules and fan trays are powered only after the DC output from the power modules are equalized and coupled. A wiring clip is provided above each 220V/110
