Cisco NCS4009-SYS-DC: Technical Architecture,
Platform Overview and Core Functionality Th...
The CBR-SUP-FILTER= is a replaceable air filter designed for Cisco’s modular chassis systems, including the ASR 9000 Series and NCS 5500/5700 platforms. It prevents dust and particulate ingress into critical components like power supplies and supervisor engines, ensuring optimal thermal performance and reducing hardware failure risks in harsh or high-pollution environments.
Q: Does the CBR-SUP-FILTER= impact chassis airflow or cooling efficiency?
A: No. Its low-restriction design maintains CFM airflow rates required for proper cooling while filtering contaminants. Clogged filters, however, can trigger thermal alarms—monitor via Cisco IOS XR or DNA Center alerts.
Q: Can it be cleaned and reused?
A: No. Unlike washable filters, the CBR-SUP-FILTER= is disposable to avoid compromising filtration efficiency.
Q: Is it required for warranty compliance?
A: Yes. Cisco mandates using certified filters in environments exceeding ISA-71.04-2013 G3 severity to maintain hardware warranties.
For guaranteed compatibility, the CBR-SUP-FILTER= is available through itmall.sale’s Cisco maintenance parts inventory. This supplier offers bulk pricing for enterprises managing large-scale deployments, ensuring consistent stock for proactive maintenance.
In a semiconductor fabrication plant deployment, the CBR-SUP-FILTER= extended ASR 9904 service life by 18 months by blocking abrasive silicon dust. However, neglecting scheduled replacements led to two emergency shutdowns—underscoring the need for automated inventory tracking. For multi-chassis setups, synchronize filter replacement cycles with quarterly maintenance windows to minimize operational disruptions.
