You can use any combination of SFP modules. Refer to the switch module release notes for the list of
SFP modules that the switch module supports. Each port must match the wave-length specifications on
the other end of the cable, and the cable must not exceed the stipulated cable length for reliable

For a dynamically assigned IP address, disconnect the PC from the switch module, and reconnect
the PC to the network. The network DHCP server assigns a new IP address to the PC.
For a statically assigned IP address, change it to the previously configured IP address.
