Install the PoE power entry module

3) Fasten the screws on the top of the PoE entry module with a Philips

screwdriver.

3.8.3 Connecting PoE Power Cables

Note:

This section only focuses on the cable connection between the external

PoE power supply and the S9500 series switch. For the installation of the

external PoE power supply, see the manual accompanying the power

supply.

I. Grounding the PoE chassis

Follow these steps to ground the PoE chassis:

1) Connect the wiring terminal (with one M6 hole) of the 6 AWG cable to

the grounding screw on the rear panel of the switch, as shown in

Figure 3-19

2) Connect the other end of the cable to the grounding bar or other

grounding terminals.
