BCM56504B2IEB

Overview

The BCM56504B2IEB is a 24-port Gigabit Ethernet multilayer switch featuring four 10 GbE/HiGig ports. It supports IEEE 802.3az Energy Efficient Ethernet and provides hardware-based QoS with eight priority queues per port. The device integrates advanced security features including MACsec encryption and ACLs for traffic filtering. It utilizes a high-performance switching fabric to ensure non-blocking throughput across all ports.

Feature Summary

• Integrates four 10 GbE uplink ports compatible with HiGig interfaces for high-speed aggregation
• Supports IEEE 802.3az Energy Efficient Ethernet to reduce power consumption during low load periods
• Provides hardware-accelerated Layer 3 routing capabilities alongside comprehensive Layer 2 switching functions

Applications

• Enterprise core and distribution layer switching infrastructure
• Data center top-of-rack aggregation switches
• Service provider edge networking equipment

Procurement Notes

Verify the specific suffix B2IEB against official Broadcom documentation to confirm package type, temperature range, and RoHS compliance status. Ensure the source document explicitly identifies this part number as a valid commercial offering rather than an engineering sample or obsolete variant before proceeding with acquisition.

Selection Notes

Select this component when a design requires a fixed configuration of twenty-four Gigabit ports combined with four dedicated 10 Gigabit uplinks. It is suitable for applications needing integrated hardware-based security and energy efficiency without requiring external management processors for basic switching operations.

Part Context

This part belongs to the Broadcom Trident family of switching solutions, designed for high-density access and aggregation layers. It serves as a specialized variant within the BCM5650x series, distinguished by its specific port count and uplink configuration compared to other members like the BCM56502 or BCM56503.

Replacement Considerations

Publicly confirmed substitutes include the BCM56502B2IEBG and BCM56503B2IEBG. These alternatives offer similar architectures but differ in the number of available 10 GbE uplink ports.
