Cisco Cisco Isr 1100 4 Ports Dsl Annex Am And Ge Wan Router — [SHORT_DESCRIPTION] (Cisco)

How Much Does Cisco ISR 1100 4 Ports DSL Annex A/M And GE Wan Router Cost in 2026?

As of June 2026, the Cisco ISR 1100 4-Port DSL Annex A/M and GE WAN Router is priced in the range of $43 for a used unit in B-grade condition. This price reflects a typical 40–60% savings compared to the cost of a new unit, which can exceed $100 depending on configuration and vendor. Refurbished units from vendors like Axus Technology and Covalent Materials typically fall within this range, though prices may vary slightly based on the unit’s service history and included accessories.

Used units in this price range are generally sourced from decommissioned branch office deployments and are typically 5–10 years old. While they can still perform reliably for basic routing and DSL connectivity, it's important to note that older hardware may not support the latest firmware updates or security patches. A failed unit in a branch office can lead to up to $1,200 in lost productivity per day, depending on the business size and reliance on remote connectivity. Always verify the unit's production year and test for functionality before purchase.

Cisco ISR 1100 4 Ports DSL Annex A/M And GE Wan Router Specifications and Compatible Tools

The Cisco ISR 1100 is a modular, fixed-form-factor router designed for small to midsize branch offices. It features four ports, including DSL Annex A/M and one Gigabit Ethernet (GE) WAN port. The device typically supports up to 100 Mbps throughput and operates on a Cisco IOS XE software stack. It is commonly used in environments requiring secure, reliable, and cost-effective connectivity.

The typical lifecycle of this unit is around 7–10 years, depending on usage and environmental conditions. It is often paired with Cisco 880 series routers and 2900 series switches for extended network capabilities. However, it is not compatible with newer Cisco ASR 1000 series platforms due to differences in form factor and software architecture. A mismatch in compatibility can lead to configuration errors or failed deployments, costing up to $800 in troubleshooting and downtime.

What to Check Before Buying a Used Cisco ISR 1100 4 Ports DSL Annex A/M And GE Wan Router in 2026

1. Production Year: Ensure the unit was manufactured between 2016 and 2020. Units older than 2015 may lack critical firmware updates and support.

2. DSL Port Functionality: Use a DSL line tester to verify Annex A/M compatibility and signal strength. A failed DSL port can render the unit unusable in its primary function.

3. GE WAN Port Test: Conduct a throughput test using a 1 Gbps link. A port that fails to sustain 900 Mbps or higher should be rejected.

4. Firmware and Software: Confirm the unit can run Cisco IOS XE 16.9 or later. Units unable to support this version may be incompatible with modern security protocols.

5. Physical Inspection: Look for signs of overheating, such as warped plastic or discolored components. Reject the unit if the heatsink is damaged or if the fan is non-functional.

A poorly vetted unit can lead to extended downtime and configuration costs, potentially exceeding $1,500 in lost revenue and support fees.

FAQ

Q: Can I use the Cisco ISR 1100 with a modern Cisco 2960 switch?
A: Yes, the ISR 1100 is compatible with the Cisco 2960 switch series, which has been in production since 2008. However, ensure the switch firmware is updated to at least 15.2(4)E5 to avoid compatibility issues.

Q: Should I buy a used Cisco ISR 1100 if I need high availability?
A: No, this unit is not designed for high-availability configurations. For HA setups, consider the Cisco 880 or 2900 series. A failed ISR 1100 in a critical deployment can cause up to 8 hours of downtime.

Q: How long can I expect the Cisco ISR 1100 to last in a branch office?
A: With proper maintenance, the unit can last 5–7 years in a branch office setting. Beyond that, component degradation and lack of firmware support can lead to frequent failures.

Q: What is the difference between the Cisco ISR 1100 and the 880 series?
A: The 880 series supports more advanced features like dual-WAN and higher throughput. The ISR 1100 is more cost-effective but lacks the scalability of the 880 series.

Q: What is the minimum warranty I should expect from a used Cisco ISR 1100?
A: A reputable refurbisher should offer at least a 90-day warranty. Units with less than 30 days of warranty coverage are typically sourced from unverified channels and carry a higher risk of early failure.
