Introduction
Using Category 5, 5e, or 6 twisted-pair cable you can connect to another device up
to 100 m (328 ft) away. The 1000BASE-T module operates at 10, 100, and
1000 Mbps. At 1000 Mbps it operates at full duplex and supports auto-negotiation of
speed and flow control. At 10/100 Mbps it supports auto-negotiation of speed,
duplex mode (i.e., half or full duplex), and flow control. Note that you should first test
the cable installation for IEEE 802.3ab compliance. See "1000BASE-T Cable
Requirements" on page 4-5.
1000BASE-T/SFP Combination Module

Figure 1-8. 1000BASE-T/SFP Combination Module

This is a combination module, providing use of a Gigabit RJ-45 port or a Small Form
Factor Pluggable (SFP) transceiver port. If an SFP transceiver (purchased
separately) is installed in the port and has a valid link on the port, the shared RJ-45
port is disabled.
The 1000BASE-T RJ-45 port supports automatic MDI/MDI-X operation, so
straight-through cables can be used for all network connections to PCs or servers,
or to other switches or hubs. Using Category 5, 5e, or 6 twisted-pair cable you can
connect to another device up to 100 m (328 ft) away. The RJ-45 port operates at
1000 Mbps, with support for full-duplex mode and flow control.
SFP is a specification for compact, modular transceivers that are hot swappable.
The SFP port supports 1000BASE-SX, 1000BASE-LX, or 1000BASE-LH
transceivers for fiber optic connections to remote devices. An SFP transceiver port
operates at 1000 Mbps, with support for full-duplex mode and flow control.
