Description

Cisco 1921/K9 Integrated Services Router — 2x Gigabit Ethernet, 2 EHWIC Slots

This certified refurbished Cisco 1921/K9 is a 1RU modular business router from Cisco's 1900 Series ISR G2 range, with two onboard Gigabit Ethernet ports, two EHWIC expansion slots and the IP Base software licence. It is tested by Reboot IT, supplied with a power cable, and covered by a 3-month warranty.

Key Benefits

  • Two Gigabit Ethernet ports: two onboard RJ-45 10/100/1000 ports for WAN and LAN connections.
  • Two EHWIC slots: add Cisco EHWIC interface cards (one double-wide card is supported) for extra switch ports, serial, DSL or other WAN interfaces.
  • Full Cisco IOS management: serial console and auxiliary ports plus a USB mini-B console port for out-of-band configuration.
  • Compact 1RU chassis: 1 rack unit high, for a comms rack, shelf or desk.
  • Ideal for labs and spares: a common platform for CCNA/CCNP study labs, and a like-for-like spare for existing 1900 Series deployments.
  • 3-month warranty: tested by Reboot IT, a Melbourne refurbisher since 2001.

Performance in Use

The 1921 is a branch-office router. It routes between its two Gigabit Ethernet interfaces, runs Cisco IOS features such as NAT, ACLs, static and dynamic routing and DHCP, and takes EHWIC modules when you need more interfaces. It ships with 512MB of DRAM and 256MB of internal USB flash, which are also the maximums for this model.

The default licence is IP Base. Data and Security (SEC) technology packages are optional Cisco licences and are not included unless stated. Please check the IOS image and licence you need before buying.

Cisco announced end-of-sale for the 1921 in 2018, and its last date of support was 30 September 2023, so Cisco no longer releases software or security updates for it. That makes it a good fit for labs, training, spares and isolated networks, and a poor fit as an internet-facing edge router where current security patches are required.

Frequently Asked Questions

What is in the box?

The Cisco 1921/K9 router and a power cable. Rack-mount ears, console cables and EHWIC modules are not included unless the listing says so.

Which licence does it have?

IP Base, the default for this model. Data and Security technology packages are separate Cisco licences.

Does Cisco still support it?

No. Cisco's last date of support for the 1921 was 30 September 2023, so there are no further software or security updates. It remains a capable router for labs, spares and internal networks.

Can I add more ports?

Yes. The two EHWIC slots take Cisco EHWIC cards, such as Ethernet switch, serial or DSL modules. Modules are sold separately.

Has it been reset?

It has been powered on and tested. Please plan to load your own configuration on first use.

How much is shipping?

Shipping costs apply based on size and destination — rates are calculated at checkout.
