Table 2-7. RJ-45 Pin Number Allocation for 10/100/ 1000BASE-T Ethernet Port

SFP Ports

The PowerConnect 2724 switch supports two SFP transceivers combo ports

, and the

PowerConnect 2748 switch supports four SFP transceivers combo ports

for various fiber-based

modules (1000BASE-SX or 1000BASE-LX). Only one of the two physical connections of a combo

port can be used at any time. The system can switch from the RJ-45 to the SFP (or vice versa)

without a system reset. The system automatically detects the media used on a combo port, and

utilizes this information in the control interfaces.

PowerConnect 2724 switch supports SFP diagnostics. The optical transceiver provides access to a

set of parameters that can be monitored and displayed to the system administrator.

NOTE: If both RJ-45 and SFP ports are present, the SFP port will be the active port, whereas the RJ-45

port will be disabled and ignored.
