HP J9548A 20-Port Gigabit Ethernet SFP+ Expansion Module

The HP J9548A 20-Port Gigabit Ethernet SFP+ Expansion Module is designed for enterprises and organizations looking to increase port density within their existing HP network infrastructure. By adding 20 1000Base-T LAN ports through standard twisted pair cabling, this module allows network administrators to connect additional devices, workstations, or access points without deploying entirely new switches. The two SFP+ expansion slots provide further flexibility, enabling fiber or high-speed copper uplinks depending on the transceivers installed.

This module is particularly useful in environments where rack space is at a premium and consolidating port capacity into fewer chassis units is a priority. The 1 Gbps maximum data transfer rate across its ports handles typical enterprise traffic including file sharing, VoIP, and standard internet access. However, organizations with 10GbE requirements at the access layer will want to evaluate whether this module meets their throughput needs. As with all expansion modules, verifying compatibility with your specific HP switch or chassis model is essential before purchase.
