The Cisco 12000 16-Slot chassis features 16 modular card slots, two alarm panels, two high-capacity blowers, and four AC hot-swap power supplies in an 8-foot rack form factor.
The chassis measures 226.4 cm (89.1 in) in height, 63.5 cm (25 in) in width, 95.3 cm (37.5 in) in depth, and weighs approximately 317 kg (700 lb) fully populated.
Under full load, the chassis draws up to 12 kW, shared across its four AC power modules, providing N+1 power redundancy.
The chassis supports Cisco 12000 Series Line Cards, OC-48/STM-16 and OC-192/STM-64 interface processors, Multiservice Processing Modules (MSPM), and advanced services modules certified for the 12000 platform.
Two front-panel alarms provide audible and visual alerts for critical events; dual blowers deliver front-to-back airflow, ensuring optimal cooling for all installed modules.
The chassis includes four hot-swappable 3 kW AC power modules with built-in overcurrent protection and LED status indicators for easy power management.
Mount the chassis in a standard 8-foot (42U) EIA-compliant rack capable of supporting at least 700 kg of weight, with proper airflow clearance and dedicated power circuits.
Use the included front and rear mounting brackets, secure with appropriate rack screws, connect grounding straps, and verify rack leveling before powering on.
Dual high-speed blowers deliver up to 1,200 CFM of airflow, maintaining optimal operating temperatures for all line cards and midplane components.
The chassis offers N+1 AC power redundancy, dual blower modules for cooling failover, and dual EIA-compliant alarm panels for fault notification.
Schedule quarterly inspections of power modules, clean air filters monthly, verify blower operation, and update firmware on line cards as per Cisco maintenance guidelines.
Cisco provides a one-year limited hardware warranty, optional SMARTnet® service for 24×7 support, next-business-day hardware replacement, and software updates.
It operates between 0°C to 40°C (32°F to 104°F), 10% to 85% relative humidity (non-condensing), with a maximum altitude of 3,000 m (10,000 ft).
Use Cisco part numbers: RACK-BRKT-12000 for mounting brackets, BLWR1200 for blowers, PS4-3KW-AC for power modules, and contact your Cisco reseller.
The chassis includes an integrated Cisco IOS® Management Processor with CLI access via console or Ethernet, plus SNMP and CiscoWorks® support for centralized monitoring.
It meets UL 60950-1, CSA C22.2 No. 60950-1, EN 60950-1 safety standards, FCC Part 15 Class A, and CE Mark requirements for international deployments.
