HP JE185A 48-Port Gigabit Ethernet Access IPv6 Module – 48 x 10/100/1000Base-T LAN
The 48-Port Access IPv6 Module delivers forty-eight ports of high-performance Gigabit Ethernet switching over Category 5 twisted-pair cable.
This module supports on-board or local Layers 2/3/4 switching, allowing packets to remain local to the module, which reduces backplane and switch fabric loading.
This reduces congestion in the network minimizing packet loss, to enable applications to run faster across the network.
The reduction in latencies will improve the quality of video and voice traffic across the network.
