Cisco 1000 Series Integrated Services Routers - Refurbished, Used, New
Cisco 1000 Series Integrated Services Routers (ISR 1000, also sold as ISR 1100) are compact, fanless-class branch routers for small offices, retail sites, clinics and home offices that need a WAN edge with built-in switching, VPN and firewall features. The C1100 models run IOS XE and pair a Gigabit Ethernet or SFP WAN port with a 4 or 8 port LAN switch; some add VDSL2/ADSL2+ or LTE WAN, and the ISR1100-4G and ISR1100-6G are the SD-WAN edge versions of the same hardware. NetworkTigers sells ISR 1000 routers, the ISR-1100-POE4 PoE module and the PWR-66W and PWR-30W power adapters refurbished, used and new. Every unit is tested before it ships so it works when it arrives.

Which ISR 1000 do I need?
Start with the WAN circuit. For Ethernet handoff from a fiber or cable provider, the C1111 gives you two Gigabit WAN ports for dual carriers or failover. For a DSL circuit, choose the C1112, C1113, C1116 or C1117 and match the DSL type and Annex to what the carrier delivers. For cellular backup or a site with no wired circuit, choose an LTE model and confirm the modem band matches your region, which is why the US models carry a US suffix. Then count LAN devices: 4P models have four switch ports, 8P models eight, and the ISR1100-6G adds two SFP ports for fiber. If you run Cisco SD-WAN, use the ISR1100-4G or -6G. Choose an X model where you need more memory for application hosting or heavier security features. Check which power adapter is included, since the 66W adapter is needed when the PoE module is fitted.
Frequently asked questions
What does the P in a model name like C1111-8P mean?
It marks the number of LAN switch ports in the chassis layout, not PoE. PoE on supported models comes from the separate ISR-1100-POE4 module and the 66W power adapter.
Can an ISR 1000 replace a Cisco 800 series router?
In most small branch roles, yes. The ISR 1000 is the successor platform, with faster throughput, Gigabit LAN ports and current IOS XE, so configurations from an 800 series router will need to be rewritten rather than copied.
Which feature set version will my router run?
The router ships with the IOS XE version installed on the unit when we test it; each listing states what is loaded. Tell us what you need and we will confirm before shipping.
