Management
802.1Q Port-based VLANs
CLI via the console port or Telnet, embedded web management interface
3Com management: 3Com Network Supervisor, 3Com Network Director, 3Com Enterprise Management Suite
Dynamic Voice over IP:
Unique Voice VLAN feature detects the presence of IP phones and dynamically assigns switch ports to the Voice VLAN, enabling automated configuration and prioritization of VoIP traffic.
This powerful feature minimizes cost and complexity associated with adding or moving IP phones.
Prioritization and Bandwidth Management:
Eight priority queues per port enable 802.1p Class of Service / Quality of Service (CoS/QoS)
Power Description
Input Voltage 110 V AC
Input Voltage 220 V AC
Power Source Power Supply
Redundant Power Supply Yes
Physical Characteristics
Form Factor Desktop
Form Factor Rack-mountable
Height 1.7″
Width 17.3″
Depth 10.6″
Weight (Approximate) 7.28 lb
Power over Ethernet (PoE):
Provide inline power to attached devices via industry-standard 802.3af Power over Ethernet (PoE).
The internal power supply provides a power budget of 300 Watts, which is dynamically allocated to PoE ports.
Supplemental power can be provided by an optional external DC power system, supplying up to 15.4 Watts of power to all PoE ports in a switch or stack.
Security:
802.1X network access control
MD5 cipher-text authentication and clear-text authentication for RIP v2 packets and SNMP v3 traffic
RADIUS authentication ensures secure access to resources. Additionally, RADIUS Authenticated Device Access (RADA) enables authentication of attached devices via MAC address.
Port-based Access Control Lists (ACLs)
Secure Shell (SSHv2) and SNMPv3 support ensure secure management access to switches via authentication and encryption of management traffic.
