SuperStack II Switch 3900 and SuperStack II Switch 9300 10/100 Mbps to 1000 Mbps Gigabit Ethernet Switching

The SuperStack II Switch 3900 and the SuperStack II Switch 9300 (Gigabit Ethernet switch) constitute an industry- leading solution for high-density 10/100 Ethernet to Gigabit Ethernet switching.

SuperStack II Switch 3900

The SuperStack II Switch 3900 delivers full line-rate performance (over 9.8 million pps of switching performance) for up to 36 10/100 Mbps ports and from one to three 1000 Mbps ports. Multiple Gigabit Ethernet uplinks can be trunked together

to deliver an uplink with 3 Gbps of bandwidth.

The SuperStack II Switch 3900 is available in two versions: a

24- and 36-port 10/100 Ethernet/ Fast Ethernet switch. Both have one integral 1000BASE-SX port and two Gigabit Ethernet expansion slots. The rear-mounted expansion slots accept optional Gigabit Ethernet modules available for either 1000BASE-SX or 1000BASE-LX both via SC connectors. The 1000BASE-SX option supports multimode fiber links, while the 1000BASE-LX option supports single- mode fiber. The 1000BASE-LX option supports multimode fiber when used
