ASR-9910-FILTER=: How Does It Protect Cisco ASR 9910 Router Airflow Systems?

​​Defining the ASR-9910-FILTER=​​

The ​​ASR-9910-FILTER=​​ is a ​​replaceable air intake filter​​ engineered for the ​​Cisco ASR 9910 Router​​, a high-capacity platform used in service provider and enterprise core networks. This filter prevents dust, debris, and contaminants from entering the chassis, safeguarding sensitive internal components like ​​Line Cards​​, ​​Fabric Modules​​, and ​​Power Supplies​​.

​​Core Technical Features​​

• ​​Material​​: Constructed with ​​electrostatic polypropylene​​ to trap particles as small as ​​5 microns​​.
• ​​Compatibility​​: Designed exclusively for the ​​ASR 9910 chassis​​ (IOS XR 6.5.3 or later).
• ​​Lifespan​​: Cisco recommends replacement every ​​6–12 months​​, depending on environmental conditions.
• ​​Accessibility​​: Hot-swappable design allows replacement without powering down the router.

​​Why Air Filtration Matters for the ASR 9910​​

1. ​​Dust Mitigation​​: Prolongs hardware life by preventing particulate buildup on ​​heat sinks​​ and ​​fan assemblies​​, which can cause overheating.
2. ​​Compliance​​: Meets ​​NEBS GR-63-CORE​​ standards for airflow cleanliness in telecom environments.
3. ​​Cost Efficiency​​: Avoids unplanned downtime caused by clogged airflow systems, which can disrupt ​​100G/400G interfaces​​.

​​Addressing Common Deployment Questions​​

​​Q1: Can the ASR-9910-FILTER= be cleaned instead of replaced?​​
A1: No. Cisco explicitly advises ​​against reusing filters​​ due to degraded electrostatic charge and potential micro-tears.

​​Q2: How does this filter differ from older ASR 9000 series filters?​​
A2: The ​​ASR-9910-FILTER=​​ has a ​​higher particle retention rating​​ (5 vs. 10 microns) and a reinforced frame to handle higher airflow volumes.

​​Q3: What environmental conditions demand more frequent replacements?​​
A3: Deployments in dusty regions, industrial sites, or areas with ​​high pollen counts​​ may require filter swaps every ​​3–4 months​​.

​​Where to Purchase Genuine ASR-9910-FILTER= Units​​

For guaranteed compatibility and performance, source the ​​ASR-9910-FILTER=​​ exclusively from itmall.sale’s Cisco inventory. Counterfeit filters often lack proper electrostatic layers, risking compliance violations.

​​Final Observations​​

In my experience managing ASR 9910 deployments, teams often underestimate airflow hygiene until ​​thermal alarms​​ trigger. The ​​ASR-9910-FILTER=​​ isn’t a “set and forget” component—it’s a frontline defense. Skipping replacements to cut costs is a gamble, especially when a single clogged filter can throttle throughput by 30% during peak traffic. Prioritize this filter as rigorously as firmware updates.
