Alcatel-Lucent OS6850-48 Network Switch with PS-126W-AC Power Supply

The Alcatel‑Lucent OS6850‑48 is a feature‑rich, stackable Gigabit Ethernet switch designed for enterprise campus and data center access networks. Equipped with 48 ports of 10/100/1000Base‑T connectivity, this switch offers wire‑speed performance, advanced security, and comprehensive Quality of Service (QoS) capabilities. The unit comes complete with the PS‑126W‑AC power supply, providing reliable AC power conversion for the entire system.

Overview

The OS6850‑48 is part of Alcatel‑Lucent’s OmniSwitch 6850 series, known for its modular operating system (AOS) that supports both Layer 2 switching and full Layer 3 routing. The switch supports static and dynamic routing protocols, including OSPF, RIP, and BGP, making it suitable for routing at the edge. Its stacking capability allows up to eight units to be interconnected via dedicated stacking ports, forming a single logical switch with simplified management.

Key Features

• 48 Gigabit Ethernet ports with auto‑MDI/MDIX

• 4 combination SFP slots for fiber uplinks (copper/SFP)

• Stackable via 2x 10 Gbps stacking ports (virtual chassis)

• Integrated Power over Ethernet (PoE) support on all copper ports (802.3af/at)

• Advanced Layer 3 features: static routes, OSPF, RIP, VRRP, PIM‑SM

• Comprehensive security: 802.1X, MAC authentication, ACLs, DHCP snooping

• QoS with 8 priority queues per port, WRED, and traffic shaping

• Power supply: PS‑126W‑AC, 100‑240 VAC, 50/60 Hz

Technical Specifications

• Ports: 48x 10/100/1000Base‑T (RJ‑45) + 4x combo SFP

• Switching Capacity: 176 Gbps (non‑blocking)

• Forwarding Rate: 132 Mpps

• MAC Table: 32,000 entries

• VLANs: 4,096 (802.1Q)

• Stacking Bandwidth: 2x 10 Gbps (dedicated ports)

• PoE Budget: 370 W (with external power supply option)

• Power Consumption: 120 W (without PoE) / up to 400 W with PoE

• Dimensions: 44.5 mm (H) × 440 mm (W) × 380 mm (D) – 1U

• Operating Temperature: 0°C to 45°C

Applications

This switch is ideal for wiring closet access, server farm connectivity, and small‑to‑medium business core networks. With PoE, it can power IP phones, wireless access points, and surveillance cameras directly, reducing cabling complexity. The stacking feature simplifies management by treating multiple switches as a single entity.

Management and Software

The OS6850‑48 runs the Alcatel‑Lucent Operating System (AOS), which provides a robust CLI, web‑based GUI, and full SNMP support. It can be managed via the Alcatel‑Lucent OmniVista network management suite, enabling centralized configuration, monitoring, and troubleshooting. The switch supports industry‑standard MIBs and provides comprehensive logging and alarm capabilities.

Installation and Power

The PS‑126W‑AC power supply is pre‑installed, requiring only a standard AC cord. The switch can be rack‑mounted using the included brackets. For redundancy, a second power supply can be added (sold separately). The hot‑swappable fan tray ensures continuous cooling with minimal noise.

Conclusion

The Alcatel‑Lucent OS6850‑48 with PS‑126W‑AC offers a balanced combination of port density, routing intelligence, and power efficiency. Its stackable architecture and PoE capability make it a versatile choice for modern enterprise networks seeking high availability and simplified operations.
