By default, the switch selects the medium for each dual-purpose port (10/100/1000BASE-T or SFP). When a link is
achieved on one media type, the switch disables the other media type until the active link goes down. If links are active
on both media, the SFP-module port has priority, but you can use the
media-type
interface configuration command to
manually designate the port as an RJ-45 port or an SFP port.
You can configure the speed and duplex settings consistent with the selected media type. For information on configuring
interfaces, see the
Cisco Connected Grid Switches Interfaces Software Configuration Guide
.
SFP Modules
The switch Ethernet SFP modules provide connections to other devices. These field-replaceable transceiver modules
provide the uplink interfaces. The modules have LC connectors for fiber-optic connections or RJ-45 connectors for
copper connections. You can use any combination of the supported SFP modules listed in
Table 2 on page 19
