Input Voltage: 90-240 VACFeaturesFeaturesPerformance: 176.0 Gbps switching capacity, with 131.0 Mpps forwarding rate (maximum)
Layer 2 switching: full-rate nonblocking on all ports, full-/half-duplex autonegotiation, flow control, multicast filtering, IEEE 802.1Q VLAN support, IEEE 802.1p traffic prioritization, IEEE 802.3ad Link Aggregation Control Protocol, IGMP snooping
Layer 3 switching: hardware-based, dynamic routing
Power over Ethernet: IEEE 802.3af PoE injection into Category 5 or 5e LAN wiring
3Com management: 3Com Network Supervisor, 3Com Network Director, 3Com Enterprise Management Suite
Other management: CLI via console or Telnet, embedded web management interface, SNMP managementAdvanced access and distribution for medium businesses and small enterprises seeking to build a secure converged network
Wirespeed non-blocking performance: aggregate switching capacity of up to 176 Gbps
Layer 2 switching; dynamic Layer 3 routing increases performance and enhances network security
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
IEEE 802.1X network access control offers standards-based security combined with RADIUS authentication; TACACS+ also supported
RADIUS Authenticated Device Access (RADA) provides authentication of attached devices via MAC address for an additional level of endpoint security
Automatic assignment of VoIP traffic to dedicated VLANs helps ensure that critical time-sensitive traffic gets the priority needed for quality communications
Power over Ethernet delivers electrical power and data connectivity over a single Ethernet cable
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
Comes as shown on picture, if something is not on the picture it's not included unless stated otherwise.
