OVERVIEW

The 24-Gigabit (RJ-45) Port managed switches

(P0973LK) provide 20 10/100/1000Base-TX Gigabit

ports and four (4) combo ports 10/100/1000Base-TX

or SFP ports that can be populated with 1000Base-X

Mini-GBIC uplink (ISL) connector modules. If an SFP

port is populated with a Mini- GBIC then the

corresponding 1000Base-TX copper port cannot be used.

The switches allow high-performance, full-featured

layer-2 Ethernet switching in small to medium-sized

network applications.
