New TCLUG Classified Ad Category: Computer Type of Ad: For Sale Subject: HP4000M Switches I have 5 HP Procurve 4000M switches that have recently been replaced. The only reason that I have brought them out of production is that I needed switches that provided Power over Ethernet for our new Cisco phone system. Overview - High-speed⁄media- flexible uplinks including Gigabit-SX, LX, and 1000Base-T - Quality of Service through Class of Service (CoS) prioritization features - Optional redundant power supply - High performance Gigabit stacking Features - Stacking capability: single IP address management for a virtual stack of up to 16 switches including the 1600m, 2400m, 2424m, 2512, 2524, 4000m, and 8000m - RMON and extended RMON: provide advanced monitoring capabilities - Port monitoring: allows you to monitor traffic using a switched port so you can view several ports at one time with a network analyzer - Web interface: allows you to configure the switch from any Web browser on the network - Protocol filtering: provides traffic control - VLAN support and tagging: supports up to 30 port-based VLANs and dynamic configuration of 802.1Q VLAN tagging providing security between workgroups - Class of Service (CoS) tagging: sets 802.1p priority field using policy-based management - IP multicast (IGMP): prevents flooding of IP multicast traffic - Port security: prevents unauthorized access using MAC address lockdown - Switch meshing: delivers high availability with high performance - Hot swappable modules: allow you to add or swap modules without interrupting the network - Optional redundant power supply: provides uninterrupted power - Spanning Tree Protocol: provides redundant links while preventing network loops - Port trunking: for higher switch-to-switch and switch-to-server throughput and link-level redundancy - Cisco Fast EtherChannel®: provides higher throughput to other devices that support FEC - Automatic Broadcast Control (ABC): minimizes IP and IPX broadcast traffic throughout the network - TACACS+: eases administration of switch management security by using a password authentication server - Cisco Discovery Protocol (CDP): enables real-time mapping of end nodes to switch ports Ports - 40 or 48 RJ-45 10⁄100Base-TX ports (IEEE 802.3 Type 10Base-T; 802.3u Type 100Base-TX) - 1 Gig Copper module (RJ45 100/1000 Base-TX) - 3 or 4 open module slots - one RS-232C DB-9 console port Performance - Latency: <10 µs (LIFO) - Throughput: 4.67 million pps (64-byte packets) - Backplane speed: 3.8 Gbps - Address table size: 10,000 entries 3 switches have 48 copper ethernet ports 2 switches have 40 copper ethernet ports $500 each.
