J9990A - HP 5400r Zl2 20-Port 10/100/1000Base-T Poe+/4-Port 1g/10gbe SFP+ Macsec V3 Zl2 Expansion Module

Description

The HPE J9990A is a versatile expansion module designed to enhance the port density and connectivity options of HPE FlexNetwork modular switches. It offers a combination of twenty 1000Base-T (Gigabit Ethernet) RJ45 ports for standard copper network connections and four SFP+ ports, which support 10 Gigabit Ethernet transceivers for high-speed fiber optic or direct-attach copper connections. This module is ideal for scenarios requiring a large number of Gigabit Ethernet ports for end devices such as computers, IP phones, or access points, while also providing high-capacity uplinks or connections to servers and other network infrastructure components via the SFP+ ports. The flexibility of SFP+ allows for the use of various transceiver types, including short-reach, long-reach, and direct-attach cables, catering to diverse deployment needs. By integrating the J9990A module into compatible HPE FlexNetwork switch chassis, organizations can significantly expand their network capacity and capabilities. It supports the creation of high-density Gigabit Ethernet environments and facilitates the implementation of high-speed 10GbE links, contributing to improved network performance and scalability. This module is a key component for building robust and adaptable enterprise networks.
