J9991A - HP 20-Port 10/100/1000Base-T Poe+/4-Port 1/2.5/5/10gBase-T PoE+ Macsec V3 Zl2 Expansion Module

Description

The HP J9991A is a high-density, high-performance switch module designed to integrate seamlessly into HP's modular switch chassis, specifically the zl2 series. This module offers a robust combination of 20 Gigabit Ethernet ports with Power over Ethernet Plus (PoE+) capabilities and 4 uplink ports that support 10 Gigabit Ethernet, also with PoE+. This configuration provides ample bandwidth and power delivery for a wide range of network devices, including IP phones, wireless access points, and high-definition surveillance cameras. Beyond its port density and power capabilities, the J9991A module incorporates advanced security features, notably MACsec v3. MACsec (Media Access Control Security) provides hardware-based encryption at the Ethernet layer, ensuring data confidentiality and integrity between network nodes. This is crucial for organizations that need to protect sensitive data traversing their network, offering a strong defense against eavesdropping and man-in-the-middle attacks. As a component of HP's modular networking solutions, the J9991A allows for flexible and scalable network designs. Administrators can customize their switch chassis by adding or replacing modules to meet evolving bandwidth and port requirements. The module's PoE+ support simplifies network deployments by eliminating the need for separate power supplies for connected devices, reducing cable clutter and installation costs.
