IBM Ethernet Switch B48Y Cooper, 4002BY4

The IBM Ethernet Switch B48Y Copper (4002BY4) is a high-density, 48-port Gigabit solution designed for next-generation network infrastructures. It combines superior Layer 3 intelligence with powerful PoE+ capabilities, delivering up to 30W per port to support high-performance edge devices like PTZ cameras and 802.11n access points.

The B48Y excels in scalability using IronStack technology, allowing administrators to stack up to 8 units via dedicated 16 Gbps CX4 ports. This creates a single logical 384-port switch, simplifying management and reducing administrative costs. With sub-microsecond latency and hardware-based sFlow monitoring, it provides real-time protection and line-rate performance for data-intensive applications, including iSCSI storage and converged VoIP networks.

Key Specifications:

• Ports: 48 x 10/100/1000Base-T PoE+ ports and 4 Combo SFP slots.

• Stacking: Up to 8 units in a virtual chassis (384 ports total).

• Throughput: 176 Gbps non-blocking switching capacity.

• L3 Features: Full support for OSPF, RIP, VRRP-E, and PIM included.

• Availability: Modular design with redundant, hot-swappable power supplies.
