external Ethernet port to any connected external Ethernet devices. If you plan
to replace the switch with another switch, you can use the existing Ethernet
cable, provided that it remains securely attached to the Ethernet network. For
additional information about cabling the switch, see “Cabling the switch and
the SFP+ module” on page 10, the documentation that comes with the cables,
and the optional network devices to which the cables have been connected. For
