Eight LRE ports, two 10/100/1000BASE-T ports and two SFP ports make up the WS-C2950ST-8-LRE, an 8-port Cisco Catalyst 2950 Long-Reach Ethernet switch with Enhanced Image software. Two of its four uplinks are active at one time, and the LRE ports connect through RJ-21 connectors on one pair of Category 1, 2 or 3 unshielded twisted-pair cable.
Long-Reach Ethernet carries 2 to 15 Mbps in each direction over existing telephone wiring, with a profile chosen per port. Switching matrix capacity is 8.8 Gbps and maximum forwarding bandwidth is 4.2 Gbps on 64-byte packets. Shared memory is 8 MB, with up to 32 MB of SDRAM and 8 MB of Flash, and the MAC table can be configured up to 8,000 addresses.
SFP ports accept 1000BASE-SX and 1000BASE-LX modules, ordered as GLC-SX-MM and GLC-LH-SM. The 10/100/1000 ports use RJ-45 connectors. The switch runs from its internal 100 to 240 V supply or from a Cisco RPS 300, and the RPS 675 is usable as well. Cisco 575 LRE and 585 LRE customer premises equipment and the Cisco LRE POTS Splitter complete the LRE link.
The model with 24 LRE ports is the WS-C2950ST-24-LRE, which has its own page. Browse more Catalyst models in Cisco switches.
