HPE J9550 GigT v2 zl 24-port Switch Expansion Module

Detailed Specifications

The HPE J9550 is a 24-port Gigabit Ethernet v2 zl module designed to expand the connectivity and functionality of HPE's modular chassis switches. It is engineered specifically for the HPE E5400 and E8200 zl Switch Series, providing a scalable solution for increasing port density within an existing network infrastructure. This module addresses the need for seamless, high-density network expansion in enterprise campus and large branch office environments without requiring a complete hardware replacement. This expansion module delivers reliable Layer 2 and Layer 3 switching capabilities directly from the parent chassis. Each of its 24 ports supports autosensing 10/100/1000Base-T speeds, ensuring flexible connectivity for a variety of endpoint devices such as workstations, IP phones, and wireless access points. The module's integration into the zl switch architecture allows it to leverage the chassis's high-performance backplane for efficient data throughput and low-latency communication between ports. Physically, the J9550 installs into any open I/O module slot within a compatible E5400 or E8200 series chassis. Its plug-in form factor simplifies installation and hot-swappable capability allows for upgrades or replacements without significant network downtime. Once installed, the module is managed centrally through the main switch's command-line interface or web-based management platform, ensuring consistent policy enforcement and a unified management experience across the entire chassis.
