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.
‘3AC’ denotes three hot-swappable AC power modules providing N+1 redundancy; the system operates on any two supplies while the third serves as failover.
The chassis measures 8.7″ H x 22.5″ W x 18.0″ D and weighs approximately 85 lb (38.6 kg) without modules, suitable for standard 19″ rack installations.
Throughput scales with installed line cards, delivering up to 256 Gbps per I/O card and multi-terabit aggregate capacity in a fully populated 16-slot chassis.
Operating temperature: 0 °C to 40 °C; relative humidity: 10%–90% non-condensing; altitude: up to 5,000 ft (1,524 m) standard, higher with derating.
You get a console port, AUX port and in-band Ethernet management via a dedicated 10/100/1000Base-T interface running Cisco IOS CLI or SNMP.
Yes. All line cards, PSUs and blowers are hot-swappable, enabling live replacement without service disruption.
Includes a 90-day limited hardware warranty. Optional Cisco SMARTnet provides 24x7 technical support, rapid RMA, and software updates.
Mount the chassis on standard 19″ rack rails, secure front and rear brackets, install modules, connect power supplies and use the console for initial IOS setup.
Standard lead time is 2–4 weeks, subject to stock availability and configuration complexity.
Returns accepted within 30 days for full credit; RMA handled per Cisco’s warranty terms, including advance replacement options with SMARTnet.
It uses energy-optimized blowers and power modules, meets TIA-942 Tier 2 and ETSI requirements, and supports power management for lower OPEX.
With 16 modular slots and redundant infrastructure, you can incrementally add line cards and service modules to expand capacity as demands increase.
