Note
When installed in Cisco ME switches, 1000BASE-T SFP modules can operate at 10, 100, or
1000 Mbps in full-duplex mode or at 10 or 100 Mbps in half-duplex mode.
Note
By default, the SFP module ports on the Cisco ME switch are configured as network node
interfaces (NNIs). A port can be reconfigured from user network interface (UNI) to NNI and
the reverse, but only four ports on the switch can be NNIs at the same time. For more
information on configuring interfaces, see the software configuration guide.
•
These switches support the SFP module patch cable. (Order the SFP module patch cable separately,
part number CAB-SFP-50CM=.)
