Figure 82 Remove a PoE module
NOTE:
•
Do not use excessive force while installing or removing the PoE module.
• If you do not install a new PoE module in the slot, install a filler panel to prevent dust from entering the
switch and ensure the normal ventilation in the switch.
Verifying the installation
Before powering on the switch, check 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 correctly 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 correctly
connected.
