BCM5344x中文资料Enterprise Edge Switch with High Integration for 24/48 Port Systems数据手册Broadcom规格书

描述 Description

The BCM5344x switch family offers industry-leading integration and low power in a small footprint. The device offers up to 24 GbE ports and four 10GE uplink ports, in addition to 50 Gbps of stacking bandwidth in a 29x29 mm package. Offering the industry's highest level of integration, the BCM53440 has 16 embedded copper GPHYs as well as a powerful ARM A9 processor. The BCM5344x is ideal for cost sensitive edge applications, such as full L2-managed wiring closet switches for enterprise or MTU/ MDU switches for service providers.
