The Cisco 12000 16-slot chassis (SKU: 12000/16-DC) is a high-performance service provider router chassis featuring 16 full-size line‐card slots, two alarm modules, two hot‐swappable blowers, and four -48V DC power supplies for carrier-grade redundancy.
The chassis offers 16 full-size line-card slots that support a wide range of Gigabit Ethernet, Packet over SONET, OC-192, POS, and ATM modules for maximum port density and flexibility.
The system ships with four hot‐swappable -48V DC power modules in an N+1 redundancy configuration, ensuring continuous operation even if one supply fails.
Two hot‐swappable blowers provide front-to-back airflow with N+1 redundancy to maintain optimal operating temperatures under full load.
Two alarm modules deliver both chassis- and module-level fault notifications, supporting SNMP traps and local LED indicators for proactive alerting.
The Cisco 12000 16-slot chassis supports a backplane capacity of up to 1.92 Tbps, enabling high-throughput core and edge routing services.
It supports all Cisco 12000-series line cards, including Gigabit Ethernet, Packet over SONET, OC-192 POS, ATM, and MPLS-enabled modules.
The chassis runs Cisco IOS and Cisco IOS XR, delivering carrier-class feature sets, non-stop forwarding, and modular software upgrades.
This chassis is ideal for service provider core routing, high-performance Internet peering, MPLS backbones, and large data center aggregation.
The chassis is a 10U rack-mountable unit measuring 19" W x 27" D x 17.5" H and weighs approximately 88 lbs when fully loaded.
Operating temperature ranges from 0°C to 45°C, with relative humidity between 10% and 85% non-condensing in standard data center environments.
Mount the chassis in a standard 19-inch rack, secure grounding, insert line cards and power supplies, then power on and configure via console or management interface.
Perform periodic firmware upgrades, monitor LED alarms for fan or power failures, and replace any failed modules or power supplies to maintain uptime.
The chassis includes a 90-day limited warranty; Cisco SMARTnet service contracts are available for 24×7 hardware replacement and software support.
Use Cisco service part numbers (SPNs) to order power supplies, blowers, alarm modules, and line cards through authorized Cisco resellers or the Cisco portal.
No, the 12000/16-DC chassis is designed exclusively for -48V DC power modules and does not support AC power modules.
It delivers high availability through N+1 redundancy in power supplies, blowers, and alarm modules, combined with non-stop forwarding and in-service software upgrades.
