Silver rack-mount network switch with 48 RJ-45 ports and four SFP slots

HPE Networking Instant On

HPE Networking Instant On 2920-48G J9728A 48-port managed network switch

SKU CH-8HTN-ENPES

A managed 48-port Gigabit switch with four SFP combo ports, 176 Gbps capacity and stackable design for rack mounting

  • 48 Gigabit RJ-45 ports connect wired devices directly
  • 4 combo SFP slots add fibre uplinks without extra hardware
  • 176 Gbps switching capacity handles heavy traffic loads
  • 9 Mpps throughput keeps latency low under load
  • Stackable design with two expansion slots scales as you grow

48-Port Gigabit Managed Switch

The HPE Networking Instant On 2920-48G J9728A is a rack-mountable, stackable managed switch built for business networks that need 48 copper Gigabit ports plus four combo SFP uplinks. It runs an ARM processor at 625 MHz with 512 MB SDRAM and 1 GB flash, supporting Layer 2 and basic Layer 3 static routing for departmental or branch deployments.

176 Gbps Switching Capacity Limit

The switch delivers 176 Gbps switching capacity and 130.9 Mpps throughput across its 44 RJ-45 ports and four combo SFP interfaces. All copper ports negotiate 10, 100 or 1000 Mbps speeds, while the SFP slots accept mini-GBIC modules for fibre uplinks. The internal power supply operates on AC 120/230 V, and the unit complies with IEEE 802.3az Energy Efficient Ethernet for lower idle power draw.

Check Rack Space and Uplink Modules

Before ordering, verify that your rack can accommodate a 17.4-inch deep chassis and that you have the required SFP transceivers for any fibre links, as the four combo ports share bandwidth with the last four RJ-45 ports. Ensure your management station can reach the RS-232 console or mini-USB port for initial configuration, and confirm that stacking modules are available if you plan to join multiple units.

Questions about this item

Should I pick the 44 RJ-45 ports plus 4 combo SFP model or a different port mix?

This unit provides 44 copper 10/100/1000 ports and 4 combo Gigabit SFP slots, so you can run up to 48 copper links or swap any four for fibre modules.

What does the 176 Gbps switching capacity mean for daily traffic?

The 176 Gbps backplane can forward 130.9 Mpps, letting all 48 ports run at line-rate Gigabit simultaneously without internal blocking.

Which stacking interface does the 2920-48G use and how many units can it link?

A dedicated stacking module slot accepts one stacking module, allowing the switch to join an HPE 2920 stack over the proprietary stacking bus.
