A cornerstone for our backbone. The 3AC power redundancy on this 16-slot chassis ensures 100% uptime for our core services. Robust and highly reliable hardware.
Excellent thermal management with the dual blowers. This chassis handles high-density line cards effortlessly, making it a perfect fit for our carrier-grade infrastructure.
The integrated alarm system is a lifesaver for proactive maintenance. It's a heavy-duty, professional-grade router that provides consistent performance under massive throughput.
Rock-solid stability for our regional hub. The 16-slot capacity allows for significant scaling, and the triple AC power modules provide great peace of mind.
Highly impressed with the longevity of this chassis. Even under heavy load, it remains cool and efficient. A true workhorse for any large-scale ISP.
The Cisco 12000/16-AC3 is a high-capacity service router chassis featuring 16 module slots, dual alarm panels, two blower cooling units, and three AC power supplies for scalable, carrier-grade networking.
Key features include 16 hot-swappable slots, redundant alarms, dual blowers, triple AC power modules, modular IOS support, high throughput and superior scalability.
It supports all Cisco 12000-GSR line cards, PICs and multi-service modules, including OC-48/STM-16, POS, ATM, Gigabit Ethernet and DWDM interface cards.
Two hot-swappable blowers maintain optimal airflow across all line cards; if one blower fails, the second automatically increases speed to sustain cooling without service interruption.
