HPE A5120-48G SI network switch

SKU CH-1JJM-GCAYD MPN A5120-48G

A 48-port manageable Layer 3 switch with Gigabit SFP uplinks and single IP management

  • Switch TypeLayer 3 Switch
  • Layer 3 routing simplifies network traffic management
  • 48 Gigabit ports deliver high-density wired connectivity
  • Gigabit SFP uplinks enable flexible fibre expansion
  • Single IP management reduces administrative overhead
  • Intelligent design supports high-performance switching demands

48-port Layer 3 switch

The HPE A5120-48G SI is a manageable Layer 3 switch built for high-density Gigabit access. It provides 48 ports for wired connectivity and supports static routing at Layer 3. The switch is designed for straightforward installation and single IP address management across the stack. It suits networks that need intelligent, manageable aggregation.

Managed networks needing static L3 routing

This switch fits environments that require a manageable Layer 3 device with high port density and static routing. It is not intended for deployments that need dynamic routing protocols or advanced Layer 3 feature sets. Buyers who require PoE power delivery on the access ports should look elsewhere. Networks demanding modular uplink options beyond fixed Gigabit SFP will need a different platform.

JE072A part number

The manufacturer part number JE072A identifies this exact A5120-48G SI model. Verifying this number ensures compatibility with existing HPE A5120G SI series infrastructure and licensing. Using a different part number risks mismatched firmware or feature support. Always confirm JE072A against procurement records before deployment.

Questions about this item

How do I install the HPE A5120-48G SI switch and what step is often missed?

Rack-mount the unit, connect the 48 Gigabit ports and Gigabit SFP uplinks, then configure a management IP so the single IP address management feature can control the stack; skipping the IP assignment leaves the switch unmanaged.

What maintenance or replacement will the HPE A5120-48G SI switch need later?

Plan to clean the internal fans and air vents periodically; the SFP transceivers in the uplink slots are hot-swappable and should be replaced if link errors appear.

What limit appears first on the HPE A5120-48G SI switch under sustained heavy traffic?

The 48 Gigabit access ports and Gigabit SFP uplinks saturate at line rate, so aggregate throughput hits the port-speed ceiling before the Layer 3 static routing table fills.
