Power over Ethernet (IEEE 802.3af) compliant (Switch 2650-PWR/Switch 2626-PWR): provides up to 15.4W per port to power IP phones, wireless access points, Web cameras, and more (2650-PWR may require an external power supply to provide full 15.4W for all 48 PoE-ready ports)
13.6 Gbps (2650 and 2650-PWR)/9.6 Gbps (2626 and 2626-PWR) backplane: wire-speed non-blocking architecture for low latency throughput
Optional external redundant power supply (Switch 2650-PWR/Switch 2626-PWR): provides uninterrupted power; sold as an accessory
Dual-personality functionality: two 10/100/1000 ports or mini-GBIC slots for optional fiber connectivity such as Gigabit-SX, -LX, or -LH
Basic IP routing: enables automatic routing with up to 16 external routes-including one default route-in IP networks
Rapid Convergence Spanning Tree Protocol (802.1w): increases network uptime through faster recovery from failed links
802.3ad Link Aggregation Control Protocol (LACP) and HP trunking: support up to 6 trunks, each with up to 4 links (ports) per trunk; trunking across modules is supported
Cisco Fast EtherChannel® (FEC): supports Cisco's proprietary FEC trunking protocol
802.1X and RADIUS network login: control port-based access for authentication and accountability
Port security: prevents unauthorized access using MAC address lockdown
TACACS+: eases switch management security administration by using a password authentication server
Secure Shell (SSH): encrypts all transmitted data for secure remote access over IP networks
Secure Sockets Layer (SSL): encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch
VLAN: supports up to 30 port-based VLANs, GVRP, and 802.1Q VLAN tagging
Traffic prioritization (802.1p): allows real-time traffic classification into 8 priority levels mapped to 4 queues
RMON and SMON: provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events
Stacking capability: single IP address management for a virtual stack of up to 16 switches, including the 2500 series, 2600 series, 2800 series, 4000m, 6108, 8000m, and 4100gl series
HP Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100 and 10/100/1000 ports
Group VLAN Registration Protocol (GVRP): allows automatic learning and dynamic assignment of VLANs
Cisco Discovery Protocol (CDP): enables real-time mapping of nodes to switch ports
Friendly port names: allow assignment of descriptive names to ports
Secure access to manage the switches: all access methods-CLI, GUI, or MIB-are securely encrypted through SSHv2, SSL, and/or SNMPv3
