CISCO WS-C2948G-GE-TX 48 port Switch Networking

DESCRIPTION THE CISCO CATALYST 2948G-GE-TX HAS AUTOSENSING 48 10/100/1000BASE-T PORTS AND 4 SMALL FORM-FACTOR PLUGGABLE (SFP) PORTS, PROVIDING A TOTAL OF 52 GIGABIT ETHERNET PORTS. THE 4 SFP PORTS ARE WIRE-SPEED, AND THE 48 10/100/1000BASE-T PORTS CAN BURST TO GIGABIT ETHERNET LINE RATE AND SHARE 12 GBPS OF CAPACITY (OR 6 GBPS FULL-DUPLEX) INTO THE SWITCHING FABRIC. ALL PORTS CAN USE CISCO GIGABIT ETHERCHANNEL OR IEEE 802.3AD FOR HIGH-SPEED INTERCONNECTION APPLICATIONS. ALL PORTS USE THE STANDARD IEEE 802.3X FLOW CONTROL (PAUSE FRAME) MECHANISM TO CONTROL GIGABIT ETHERNET HOST TRAFFIC. THE CISCO CATALYST 2948G-GE-TX USES THE SAME FEATURE-RICH CISCO CATALYST OS SOFTWARE AS THE CISCO CATALYST 2948G, THE CISCO CATALYST 2980G-A, AND CISCO CATALYST 4000 SERIES SWITCHES.
