3CR17772-91 (JE063A) 3Com Switch 4500G PWR 48-Port L3 Switch

HP 4500-48G-PoE Switch (JE063A) 


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

Product Specifications

  • 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
