HPE J9836A 2920-48G-PoE+ 740W switch module

SKU CH-G51C-D2G2E MPN J9836A

Layer 3 switch module with 48 Gigabit Ethernet ports, 740W PoE+ and four SFP uplinks

  • 48 Gigabit ports for high-density connectivity
  • 740 W PoE+ budget powers many devices
  • Layer 3 switching enables advanced routing
  • Four dual-personality ports give SFP flexibility
  • Modular design with seven expansion slots

48-Port PoE+ Layer 3 Switch

This HPE 2920-48G-PoE+ module delivers 48 Gigabit Ethernet ports with Power over Ethernet Plus support. It operates as a Layer 3 switch with a 740W PoE budget for connected devices. Four dual-personality ports accept copper or SFP transceivers for uplink flexibility. The modular design includes three expansion slots for optional 10 Gigabit or stacking modules.

Network Teams Needing High Port Density

IT departments requiring 48 powered ports for VoIP phones, wireless access points or cameras will fit this chassis. The 740W budget supports many simultaneous PoE+ endpoints without external injectors. Organisations needing only 24 ports or a non-PoE model should evaluate smaller 2920 variants instead. Environments without SFP uplink requirements may find the dual-personality ports unnecessary.

Rack Mount with Optional Uplink Modules

The switch installs in a standard rack and uses its three expansion slots to add 10 Gigabit SFP+ or 10GBASE-T uplinks. A two-port stacking module can join multiple units into a single logical stack. Four dual-personality ports free fixed copper ports by moving uplinks to fibre. The 740W internal supply powers both the switch and all PoE devices without extra hardware.

Questions about this item

What SFP or SFP+ transceivers must I already own to use the four dual-personality ports on the J9836A?

The four dual-personality ports accept standard SFP transceivers for 1000BASE-X or SFP+ transceivers for 10GBASE-R; you supply the modules that match your fibre or copper link.

Can I stack this 2920-48G-PoE+ 740W switch with an older 2920-24G unit that has no PoE?

Yes, the two-port stacking module works across the 2920 series, so a non-PoE 24G switch can join the same stack as this 48-port PoE+ model.

How do I confirm the 740 W PoE+ budget is actually delivering power to all 48 ports after setup?

Check the front-panel PoE LEDs and run "show power-over-ethernet" in the CLI; it reports real-time draw per port and total consumption against the 740 W limit.
