Removing the PoE module
To remove the PoE module:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2. Use a Philips screwdriver to completely loosen the captive screws on the PoE module.
3. Pull the ejector levers outward (see callout 1 in Figure 55). Then pull out the PoE module slowly
along the guide rails (see callout 2 in Figure 55).
4. If you do not install a new PoE module in the slot, install the filler panel to prevent dust from
entering the switch and ensure the normal ventilation in the switch.

NOTE:
Do not use excessive force while installing or removing the PoE module.
Verifying the installation
After you complete the installation, verify that:
There is enough space for heat dissipation around the switch, and the rack or workbench is stable.
The grounding cable is securely connected.
The correct power source is used.
The power cords are properly connected.
All the interface cables are cabled indoors. If any cable is routed outdoors, verify that the socket
strip with lightning protection and lightning arresters for network ports have been properly
connected.
