Technical specifications

 

The 3Com Switch 5500G-EI 24-Port is a premium stackable 10/100/1000 switch with

Enhanced Image (EI) software for businesses running the most demanding network

applications requiring the highest "five 9s" network uptime. 24 SFP ports operate at Gigabit

speeds; four of these ports are dual-purposed with four 10/100/1000 ports. Expansion

module slot offers additional Gigabit or 10-Gigabit Ethernet connectivity.

Ports: 24 Gigabit SFP ports, 4 of which are dual-personality operating as SFP or auto-

negotiating 10BASE-T/100BASE-TX/1000BASE-T; RPS power port (-48 VDC); RJ-45

console port; 2 dedicated stacking ports; 1 optional module slot


- Last two combo SFP ports support up to two dual-mode Fast Ethernet SFPs

- Performance: 192.0 Gbps switching capacity, 136.9 Mpps forwarding rate, maximum 

  (with 2-port 10-Gigabit module); 107.1 Mpps forwarding rate, maximum (with no 

  optional modules)

- Stacking: Up to 8 switch units, 448 Gigabit ports, with 16 10-Gigabit ports; 3Com
