10/100 BASE-T Downlink Ports

You can set the 10/100BASE-T downlink ports to operate at 10 or 100 Mb/s in full-duplex or half-duplex mode. You can
also set these ports for speed and duplex autonegotiation in compliance with IEEE 802.3AB. (The default setting is
autonegotiate.) When set for autonegotiation, the port senses the speed and duplex settings of the attached device and
advertises its own capabilities. If the connected device also supports autonegotiation, the switch port negotiates the best
connection (that is, the fastest line speed that both devices support, and full-duplex transmission if the attached device
supports it) and configures itself accordingly. In all cases, the attached device must be within 328 feet (100 meters).
100BASE-TX traffic requires Category 5 cable. 10BASE-T traffic can use Category 3 or Category 4 cables.
When connecting the switch to workstations, servers, routers, and Cisco IP phones, make sure that the cable is a
straight-through cable.
100/1000 Mb/s SFP Module Uplink Slots
The IEEE 802.3u 100 Mb/s SFP module uplink slots provide full-duplex 100 or 1000 Mb/s connectivity over multi-mode
(MM) fiber cables or single-mode (SM) fiber cables. These ports use a SFP fiber-optic transceiver module that accepts
a dual LC connector. Check the SFP specifications for the cable type and length.
