Verifying the installation
After you complete the installation, verify the following items:
•
There is enough space for heat dissipation around the switch, and the rack is stable.
•
The grounding cable is securely connected.
•
The power source is as required by the switch.
•
The power cords are correctly connected.
•
If part of the network cable for a port is routed outdoors, verify that a network port lightning
protector is used for the port.
•
All the interface cables are cabled indoors. The switch does not support outdoor cable routing.
