The 3Com 3CR17772-91 Switch 4500G is a stackable 10/100/1000 Ethernet 48 port switch that provides secure, flexible LAN connectivity and advanced voice-optimized features such as auto-voice VLAN and QoS. Optional 10-Gigabit uplinks via local connection modules or XFP transceivers supply highest-speed connections to other similarly equipped devices.
48 auto-negotiating 10BASE-T/100BASE-TX/1000BASE-T ports supporting IEEE 802.3af in-line PoE; 4 of these ports are dual-personality 10/100/1000 or SFP Gigabit ports
Wirespeed non-blocking performance: aggregate switching capacity of up to 176 Gbps
Use clustered stacking for up to 32 devices (Switch 4200G, 4500G 5500 and 5500G switches)
Add switches to the cluster when needed� without increasing management difficulty and expense and manage all as a single entity
Up to four 10-Gigabit ports per switch using two rear slots and dual-port 10-Gigabit modules; economical CX4 for short-distance stack connections, or XFP for longer 10-Gigabit distances
