48-Port Managed Switch for Access Layer

The HPE Networking Instant On 2920-48G-PoE+ is a Layer 3 managed switch built for rack mounting. It provides 48 Gigabit RJ-45 ports, of which 44 deliver PoE+ power for devices such as access points and IP cameras. Four combo Gigabit SFP ports allow fibre or copper uplinks. An internal power supply handles all system and PoE loads.

Suited for PoE-Heavy Wired Networks

This switch suits environments that need many powered ports in a single rack unit, such as offices, schools or retail sites deploying VoIP phones and wireless APs. It is not intended for deployments that require only a few PoE ports or for builders who need high-density 10 GbE uplinks beyond the four combo SFP interfaces.

44 PoE+ Ports Decide Fit

The defining specification is the count of 44 PoE+ copper ports combined with four combo Gigabit SFP ports. If your design calls for exactly that number of powered connections and uplink flexibility, the switch matches the requirement; if you need more or fewer powered ports, a different model is appropriate.

Questions about this item

Should I use all 44 PoE+ ports or save the 4 SFP uplinks for fibre?

The switch provides 44 RJ-45 ports with PoE+ and 4 combo Gigabit SFP slots; use the SFP ports for longer fibre uplinks and the RJ-45 ports for powered devices.

What does the 44-port PoE+ count mean for powering phones and cameras?

Each of the 44 RJ-45 ports can deliver PoE+ power to IP phones, cameras or access points while simultaneously passing 10/100/1000 data.

Are the 4 SFP slots limited to Gigabit speeds only?

Yes, the 4 combo SFP ports operate at Gigabit speed and share bandwidth with the corresponding RJ-45 ports when used.
