Network interfaces
This section describes the port types in the switches.
10/100/1000 Mbps RJ45 ports: The 10/100/1000 RJ45 ports on the devices use
auto-sensing and auto-negotiating to determine the speed (10 Mbps, 100 Mbps, or
1000 Mbps) and duplex mode (full-duplex or half-duplex) of the port at the other
end of the link and adjust port speed accordingly.
100/1000 Mbps SFP ports: The 100/1000 MbE SFP ports on the devices use
auto-sensing and auto-negotiating to determine the speed (100 Mbps or 1000
Mbps) and duplex mode (full-duplex or half-duplex) of the port at the other end of
the link and adjusts port speed accordingly. These ports are sometimes referred to
as Hybrid Fiber ports.
The 100/1000 Mbps Ethernet ports use Small Form Factor Pluggable (SFP)
MSA-compliant transceivers.
Combination ports: On devices with combo ports, one port out of each pair of
copper and fiber ports can be active at a time. Combo ports are numbered 1-4. For
example, you can use either copper port 2 or fiber port 2, but not both at the same
time. You can use a combination of fiber and copper ports or all copper or all fiber
ports, as needed.
If you attach both the copper and fiber connectors for a port to the network, the
fiber connectors take precedence over the copper connectors. These ports support
true media automatic detection, meaning the device selects the fiber or copper
connector based on link availability. If a fiber link cannot be established, the device
selects the copper media.
