The nine-slot Catalyst 6509-NEB switch has vertically-oriented slots but the backplane architecture and functionality is identical to the Catalyst 6509 switch.

The Catalyst 6000 series consists of the six-slot Catalyst 6006 switch and the nine-slot Catalyst 6009 switch. The Catalyst 6500 series consists of the six-slot Catalyst 6506 switch, nine-slot Catalyst 6509 switch and the nine-slot Catalyst 6509-NEB switch.

These high-performance, modular, frame-based switches support high-density Fast Ethernet and Gigabit Ethernet in both campus-backbone and server-aggregation environments. The Catalyst 6006 and the Catalyst 6009 switches have a 32-Gbps switching capacity, while the Catalyst 6506, Catalyst 6509, and Catalyst 6509-NEB switches can support a backplane architecture that scales from 32 Gbps to 256 Gbps.

All platforms share the same supervisor engines, switching modules, and software, and support redundant configurations of supervisor engines, power supplies, and port interfaces.

• Supports supervisor engine with two gigabit interface uplinks
• Supports the MSFC and PFC
• Supports optional redundant supervisor engine with two Gigabit Ethernet uplink ports (uplink ports are fully functional on redundant supervisor engine in standby mode)
• Supports up to eight additional switching modules (Ethernet, Fast Ethernet, Gigabit Ethernet, and ATM)
• Supports the Multilayer Switch Module
• All modules are hot-swappable
• Supports redundant, hot-swappable AC-input or DC-input power supplies
• Fan assembly is hot-swappable
• Backplane-mounted clock modules are redundant
• Supports vertically aligned modules with slot numbering from right to left
  
  

Pre-owned CISCO 7206VXR/300 (A+ Certified)   
Part # Cisco7206VXR/300 Router

  The Cisco 7206 supports multiprotocol, multimedia routing and bridging over a wide variety of LAN and WAN interface types. The Cisco 7206 is part of the Cisco 7200 series routers, which consists of the 2-slot Cisco 7202, 4-slot Cisco 7204 and Cisco 7204VXR, and 6-slot Cisco 7206 and Cisco 7206VXR.

Network interfaces reside on port adapters that provide the connection between the router's three Peripheral Component Interconnect (PCI) buses and external networks. The Cisco 7206 has six slots (slot 1 through slot 6) for the port adapters, one slot for an Input/Output (I/O) controller, and one slot for a network processing engine. You can place the port adapters in any of the six available slots.

There are bays for up to two AC-input or DC-input power supplies. The Cisco 7206 will operate with one power supply. While a second power supply is not required, it allows load sharing and increased system availability.

Pre-owned CISCO MCS-7830  (A+ Certified) 

The Cisco Media Convergence Server 7830 (MCS-7830) is a high-availability server platform for Cisco AVVID (Architecture for Voice, Video and Integrated Data). The MCS-7830 is a member of the MCS-7800 series server family, which also includes the cost-effective MCS-7820 and the Cisco AVVID IP telephony starter kits. With Cisco CallManager software preinstalled in this fault-tolerant server, the wide-scale deployment of industry-leading Cisco IP telephony solutions has never been easier. The Cisco MCS-7830 is an integral part of a complete, scalable architecture for a new generation of high-quality IP voice solutions that run on the enterprise data network. The MCS-7830 delivers the high performance and availability demanded by today"s enterprise networks and represents a turnkey solution that is easy to deploy and highly cost-effective.

The Cisco Unified Open Network Exchange (Cisco uOne), an integral part of Cisco AVVID, is a voice and unified-messaging application. The first commercially available version of Cisco uOne 4.1E-Entry Edition-runs on the Cisco Media Convergence Server 7830 (MCS-7830) and is available for the North American market.

Pre-owned CISCO Cache Engine 500  (A+ Certified) 

Cisco's next-generation Cache Engine 500 series solutions enable ISPs and enterprises to reduce WAN bandwidth usage, accelerate network performance, and increase network scalability. Utilizing the intelligence of the network, the Cisco Cache Engine 500 series solutions localize traffic patterns by transparently caching frequently accessed content and then locally fulfilling successive requests for the same content. Because they are integrated into the network infrastructure, they have a low cost of ownership, enabling ISPs and enterprises to cost-effectively deploy the Cisco network caching solution on a wide-scale basis and gain the benefits of caching throughout their network.

Pre-owned CISCO Aironet Wireless Networks (A+ Certified) 

Ethernet Bridges - Building-to-Building
Wireless Solutions. The Cisco Aironet wireless  bridge series products provide high-speed, long-range wireless connections between Ethernet networks. 

Designed to connect two or more networks (typically located in different buildings), Cisco Aironet wireless bridges1 deliver high data rates and superior throughput for data-intensive, line-of-sight applications. The high-speed links between Cisco Aironet wireless bridges deliver throughput faster than E1/T1 lines for a fraction of the cost---eliminating the need for expensive and difficult-to-install leased lines or fiber-optic cable. 

• Offers up to 25-mile range
• Offers up to 11 Mbps data rate
• Links buildings into a single LAN
• Requires no license

The initial hardware investment can be quickly paid for with the money saved on leased-line service. Wireless bridges connect discrete sites into a single LAN, even when they're separated by obstacles such as freeways, railroads, and bodies of water that are practically insurmountable for copper and fiber-optic cable.
