Holding the SFP module by its sides, insert the SFP module into the port on the switch. This section describes how to install an optical module. The method used to install a copper transceiver module is the same, except that the copper transceiver module connects to a network cable instead of optical fibers. The switch can operate without a network module, but a blank module (with no ports or SFP slots) is available and should be installed when uplink ports are not required. It covers critical preparation checks, proper insertion techniques, hot-swap and safety considerations, common installation mistakes, and practical. You can add or remove SFP modules in your switch without powering off the system. 1G/10G SFP+: Standard for Gigabit and 10 Gigabit Ethernet.
