Description

Cisco ISR4351/K9 — Enterprise Branch Router for Demanding WAN Environments

  • 200 Mbps aggregate throughput for high-bandwidth branch connectivity and WAN aggregation
  • 3 Gigabit Ethernet ports configurable as WAN or LAN interfaces to suit your network design
  • 2 Network Interface Module (NIM) slots and 1 Service Module (SM) slot for modular expansion
  • Runs Cisco IOS XE with full support for BGP, OSPF, EIGRP, MPLS, VPN, and QoS
  • Integrated security features including zone-based firewall and IPsec/SSL VPN support
  • Supports optional Cisco voice, DSP, and services modules for unified communications

The Cisco ISR4351/K9 is a high-performance branch router designed for enterprises requiring reliable, high-throughput WAN connectivity at the network edge. With 200 Mbps of aggregate throughput, three configurable GbE interfaces, and a modular expansion design, it gives network architects the flexibility to tailor the router to specific branch requirements — from dual-WAN setups to integrated voice gateways.

Running Cisco IOS XE, the ISR4351 supports the full Cisco enterprise routing feature set including BGP, OSPF, EIGRP, MPLS, and advanced QoS for traffic shaping and prioritisation. Its two NIM slots accept a wide range of interface modules including T1/E1, ADSL, serial WAN, and additional Ethernet modules, while the SM slot supports higher-density voice and data service modules.

All-in-one Solution for Home Office

I was looking for an in-expensive all-in-one solution for my home office to replace my existing desktop and monitor. I found this EliteOne 800 on reboot IT for under $200. I wasn't sure what to expect. It arrived within two days!!!! I upgraded the RAM, replaced the HDD and installed Windows 11. This is unbeatable value and was the cheapest price online. Coupled with a 3-month warranty, Reboot IT are by far the best online refurbished retailer I have used. Awesome!

Fair tech for price

Fair tech for price, good specs for era, serves the purpose. The black keyboard is an interesting rubber like texture clearly by design to pad the screen and avoid the keyboard touching. Screen is great. Still looking for magic formula to enable computer use in the bright bright sunshine. Keyboard taps are loud for someone who likes silent touch. The perfect PC has to exist, like build a bear.

Works excellently as advertised.

The laptop was sold with a warning about worn keycaps. In fact they had been obviously vandalised (ex school laptops, perhaps?). The keyboard worked fine, and the rest of the laptop too. I'm using it as a file server, so I don't need the keyboard much. So very pleased, and also pleased with reboot-it's service - as always, excellent, and quick responses to any queries.
