48-port Gigabit PoE+ switch for managed networks

This Universal GS1920-48HPv2 provides 48 Gigabit Ethernet ports with PoE+ support plus 2 SFP ports for fibre uplinks. It delivers a total PoE budget of 375 W to power access points, VoIP phones and IP cameras. The switch operates in either cloud-managed or standalone mode via NebulaFlex. A rack-mount chassis simplifies installation in cabinets.

PoE budget and port-speed limits

The 375 W PoE budget is shared across all 48 ports, so the number of powered devices depends on each unit's draw. Each copper port runs at 1 Gbps full-duplex with non-blocking throughput of 2,000 Mbps per port. The 2 SFP ports accept compatible transceivers for uplink or stacking links. Total switching capacity is constrained by the 48-port Gigabit design.

Rack space and management choice

Verify that your rack has 1U of free space and adequate airflow for a metal chassis. Decide whether you will manage the switch through the Nebula cloud platform or locally in standalone mode, as feature sets differ. Confirm that your SFP modules match the switch's supported transceiver types. Ensure your powered devices comply with 802.3af or 802.3at standards.

Questions about this item

Should I choose the 48-port PoE+ model or a version with fewer ports?

The GS1920-48HPv2 provides 48 Gigabit PoE+ ports plus 4 SFP uplinks; select it when you need to power many APs, phones or cameras from one switch.

What does the 375 W per-port PoE+ figure mean once the switch is installed?

Each port can deliver up to 375 W under the 802.3at standard, but the 70 W total budget limits how many ports can run at high power simultaneously.

Which management interface does the NebulaFlex switch use and what does it cap?

NebulaFlex lets you manage the switch either through the cloud or locally; the 70 W PoE budget caps the combined power draw across all 48 ports.
