Cisco 2911 ISR 3x GbE Integrated Services Router Wired Enterprise | Wty
Cisco 2911/K9 — ISR G2 Compact Branch Router
The Cisco 2911/K9 is a second-generation Integrated Services Router with 3 Gigabit Ethernet ports, 3 EHWIC expansion slots, 256 MB Flash, and 512 MB DRAM. Backed by a 12-month warranty from Reboot IT, it delivers enterprise routing, VPN, and firewall capabilities for small-to-medium branch offices.
Key Benefits
- 3x Gigabit Ethernet Ports: Multi-WAN and LAN routing in a single device for small branch offices without extra switches
- 3 EHWIC Expansion Slots: Modular expansion with voice DSP, DSL WAN, 4G LTE, and additional GbE interface cards
- K9 Security Bundle: Hardware-accelerated IPSec encryption for site-to-site and remote-access VPN without performance overhead
- Cisco IOS 15.x: Full enterprise routing — OSPF, EIGRP, BGP, QoS, zone-based firewall, and DMVPN
- 1U Rack-Mount Form Factor: Compact chassis suited to sites with limited rack space or shallow cabinets
- 12-Month Warranty: Tested, verified, and reset to factory defaults by Reboot IT's Melbourne-based team
Performance in Use
The Cisco 2911/K9 is the entry point of the three-GbE ISR G2 family — positioned below the 2921, it handles the core routing, firewall, and VPN requirements of a small branch office in a single compact device. This eliminates the need for separate router, firewall, and VPN appliances at smaller sites, simplifying both procurement and ongoing support.
With three EHWIC slots, the 2911 can be expanded with a DSL WAN module for NBN FTTN connectivity, a 4G cellular module for automatic WAN failover, or a T1/E1 card for legacy serial WAN links. This modularity makes it a long-term investment for sites whose WAN requirements may evolve across the deployment lifecycle without requiring a router replacement.

Frequently Asked Questions
What is the difference between the 2911 and the 2921?
The 2921 has 4 EHWIC slots (vs 3 on the 2911) and more processing headroom. Both run IOS 15.x and support the same routing, VPN, and firewall features — the 2911 is more compact and cost-effective for smaller sites.
What EHWIC modules can I add?
Compatible modules include VDSL2/ADSL2+ WAN, 4G LTE cellular, additional GbE interfaces, serial T1/E1, and voice DSP cards. Refer to Cisco's compatibility matrix for your specific module.
Does the K9 designation include VPN hardware?
Yes. K9 indicates the security bundle, enabling hardware-accelerated IPSec encryption so VPN performance does not degrade the router's routing throughput.
What IOS version does it ship with?
Units ship with Cisco IOS 15.x installed and are reset to factory defaults. Contact us for the specific release version if required for your deployment.
Is the 2911 rack-mountable?
Yes. It is a 1U rack-mount device. Rack ears may or may not be included with the unit — check the listing or contact us to confirm.
How is shipping handled?
Shipping costs apply based on size and destination — rates are calculated at checkout.
What does the 12-month warranty cover?
All hardware defects and functional failures. Units are tested and reset to factory defaults before dispatch.
