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 connected.
• The selected power module matches that required by the switch.
• The power cords are properly connected.
• All the interface cables are cabled indoors. If there is any cable wired outdoors, verify that socket
strip with lightning protection and lightning arresters for network ports have been properly
connected.
