Figure 1-5 Single-Port 1000BASE-T/SFP Combo Module

The 1000BASE-T RJ-45 port and SFP slot on this module share the same

internal interface. If an SFP transceiver (purchased separately) is installed

in a slot and has a valid link, the associated RJ-45 port is disabled and

cannot be used. The switch can also be configured to force the use of an

RJ-45 port or SFP slot, as required.

When connecting to the 1000BASE-T RJ-45 port, Category 5, 5e, or 6

twisted-pair cable can be used to connect to another device up to 100 m

(328 ft) away. The 1000BASE-T port operates at 10, 100, and 1000

Mbps.

At 1000

Mbps it operates at full duplex and supports auto-negotiation of

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 4-6.

This module also provides an SFP slot that supports 1000BASE-SX,

1000BASE-LX and 1000BASE-ZX transceivers. For a full listing of the

supported transceivers, see

“Ordering Information” on page E-1.
