Description: E4500 24 POE SWCH
Mfr Part #: JE047A#ABA
The HP 4500 Switch Series are managed, stackable 10/100 Ethernet switches that provide secure, flexible LAN connectivity for enterprise and branch office networks. HP E4500 switches offer Layer 2 switching and dynamic Layer 3 routing, as well as robust security, Quality of Service (QoS), and management features to deliver intelligent edge connectivity for essential business applications. Dual-personality ports allow for both copper and fiber Gigabit uplink connections. The switch supports true stacking with the ability to stack up to eight switch units-384 10/100 ports per stack-with single IP management and distributed aggregated links for high uplink resiliency.
- Gigabit Uplinks: The HP 4500-24 model has two dual-personality ports for either 10/100/1000 or mini-GBIC SFP connectivity; other models have dual-personality dual mini-GBIC Gigabit SFP ports and ship with two 1000BASE-T SFP transceivers for copper Ethernet connections
- RMON (remote monitoring): provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events
- Layer 3 IP routing : Static IP routing, RIPv1, and RIPv2 provide routing at media speed
- Access control lists (ACLs): provide IP Layer 3 filtering based on source/destination IP address/subnet and source/destination TCP/UDP port number
- Quality of Service (QoS)
Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues.
Class of Service (CoS): sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ.
Rate limiting: sets per-port ingress enforced maximums and per-port, per-queue guaranteed minimums.
IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automated device discovery protocol provides easy mapping by network management applications.
Uni-Directional Link Detection (UDLD): monitors cable between two switches and shuts down the ports on both ends if the cable is broken, turning the bidirectional link into a unidirectional one; this prevents network problems such as loops.
Secure Web GUI: provides a secure, easy-to-use graphical interface for configuring the module via HTTPS.
Command-line interface (CLI): provides a secure, easy-to-use command-line interface for configuring the module via SSH or a switch console; provides direct real-time session visibility.
SNMPv1, v2c, and v3: facilitate centralized discovery, monitoring, and secure management of networking devices.
Gigabit Uplinks: The HP 4500-24 model has two dual-personality ports for either 10/100/1000 or mini-GBIC SFP connectivity; other models have dual-personality dual mini-GBIC Gigabit SFP ports and ship with two 1000BASE-T SFP transceivers for copper Ethernet connections.
Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100 and 10/100/1000 ports.
IEEE 802.3af Power over Ethernet (PoE): provides up to 15.4 W per port to IEEE 802.3af-compliant PoE-powered devices such as IP phones, wireless access points, and security cameras.
RMON (remote monitoring): provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events.
Dual flash images: provides independent primary and secondary operating system files for backup while upgrading.
Full-featured console: provides complete control of the switch with a familiar command-line interface (CLI).
Web interface: allows configuration of the switch from any Web browser on the network.
Multiple configuration files: allow multiple configuration files to be stored to a flash image.
- Layer 2 switching
VLAN support and tagging: support IEEE 802.1Q with 4,094 simultaneous VLAN IDs.
GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs.
Jumbo packet support: supports up to 9220-byte frame size to improve the performance of large data transfers.
IEEE 802.1ad QinQ: increases the scalability of an Ethernet network by providing a hierarchical structure; connects multiple LANs on a high-speed campus or metro network.
- Layer 3 routing
Layer 3 IP routing : Static IP routing, RIPv1, and RIPv2 provide routing at media speed.
Access control lists (ACLs): provide IP Layer 3 filtering based on source/destination IP address/subnet and source/destination TCP/UDP port number.
RADIUS/TACACS+: eases switch management security administration by using a password authentication server.
Secure Shell: encrypts all transmitted data for secure remote CLI access over IP networks.
Secure Web management with HTTPS and SSL: encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch.
IEEE 802.1X and RADIUS network logins: control port-based access for authentication and accountability.
