Alcatel PW3N-OV4NMS-HA

For network architects who refuse to compromise on resilience, the Alcatel PW3N-OV4NMS-HA delivers a service provider-grade modular chassis that scales from branch aggregation to core routing without a forklift upgrade. Unlike fixed-form routers that hit a hard ceiling, this 12 RU platform offers twelve I/O module slots and redundant control, fabric, power, and cooling—so you can grow capacity in place while maintaining carrier-class uptime.

Highlights

• 12-slot modular architecture with 2.4 Tbps full-duplex backplane capacity
• Dual control processor and switch fabric slots for hitless failover
• Four power supply bays supporting AC or DC modules (sold separately)
• Hot-swappable fan trays with front-to-back airflow for predictable thermal behavior
• NEBS Level 3 and ETSI compliance for demanding central office and data center environments

In daily use

The PW3N-OV4NMS-HA earns its place in multi-service edge and aggregation roles. With 12 I/O slots, you can mix high-density Ethernet, IP/MPLS, and Carrier Ethernet line cards as traffic patterns shift. Redundant management Ethernet and console ports simplify out-of-band access, while the chassis’s 0°C to 45°C operating range and 5% to 90% non-condensing humidity tolerance keep services running in less-than-ideal wiring closets. Because all active components—fans, power supplies, control modules, and fabrics—are field-replaceable, maintenance windows shrink from hours to minutes.
