Description

The JG421A is a half-height HMIM interface module from the HPE FlexNetwork MSR family, built to add copper Gigabit connectivity to compatible MSR3000 and MSR4000 series routers. It suits branch and enterprise sites that need extra LAN or WAN copper ports and Layer 2 access port expansion without adding a separate switch.

The module provides four RJ-45 10/100/1000BASE-T Gigabit Ethernet ports over twisted pair media, with auto-speed detection, auto duplex and MDI/MDI-X on each port. In the half-height HMIM form factor it occupies one half-height or one full-height slot, which gives flexibility in the MSR4000 chassis with its six HMIM slots (four half-height and two full-height). It is a non-PoE module and draws power from the host router chassis, so no separate power supply is needed.

It is designed for the HPE FlexNetwork MSR3000 and MSR4000 router series, including MSR4000 configurations based on the JG412A MPU-100 and JG414A SPU-200. Related modules in the range include the JG420A 2-port Gig-T, JG422A 8-port Gig-T and JG427A 24-port Gig-T PoE switch HMIM.
