Product Overview and Core Functionality The...
The Cisco ASR1000-SIP-BLANK= is a blank slot cover designed for the ASR 1000 Series routers. It serves as a critical component for maintaining chassis integrity, ensuring proper airflow, and preventing physical damage or dust ingress in unused SPA (Shared Port Adapter) slots. While often overlooked, this module plays a vital role in preserving the router’s operational efficiency and longevity.
Absolutely. Leaving slots open disrupts thermal dynamics, leading to overheating of adjacent modules. It also exposes internal components to dust or accidental physical contact.
No. The blank cover is a passive component with no software dependencies. It doesn’t consume licenses or affect routing capacity.
While blank covers seem trivial, they are mandatory for compliance with Cisco’s chassis design guidelines. Open slots can void warranties and increase failure rates of nearby components. For example, a single uncovered slot can raise internal temperatures by 5–8°C, accelerating hardware degradation.

Having managed countless ASR 1000 deployments, I’ve seen firsthand how neglecting “simple” components like blank covers leads to avoidable downtime. The ASR1000-SIP-BLANK= isn’t just a piece of metal—it’s a low-cost insurance policy against thermal failures and environmental hazards. In networking, resilience often hinges on the smallest details, and this module exemplifies that principle.
