Silver 1U rack-mount switch with 48 RJ-45 ports and four SFP cages

HPE Networking Instant On

HPE Networking Instant On 2930F 48G PoE+ 4SFP JL557A 48 port managed network switch

SKU CH-S046-ZA8GA

A 48-port managed Gigabit switch with PoE+ on every RJ-45 port, four SFP uplinks and a 740 W power budget for access points or cameras

  • 48 PoE+ ports power phones and cameras directly
  • 740 W PoE budget supports dense device deployments
  • 4 SFP uplinks enable flexible fibre aggregation
  • 104 Gbps switching capacity handles heavy traffic loads
  • Layer 3 routing with OSPF and RIP simplifies network design

48-Port Gigabit PoE+ Switch

The HPE Networking Instant On 2930F is a 1U rack-mountable Layer 3 managed switch with 48 RJ-45 ports supporting 10/100/1000 PoE+ and four Gigabit SFP uplinks. It delivers a 740 W PoE budget, 104 Gbps switching capacity and 77.4 Mpps throughput. CLI, web browser and Intelligent Management Center interfaces handle configuration.

Suits PoE-Heavy Edge Deployments

This switch fits networks that need to power many access points, cameras or phones from a single rack unit while running static or dynamic IPv4 and IPv6 routing. Buyers who need 10 GbE uplinks, a larger IPv6 routing table than 5000 entries, or a MAC table beyond 32K entries should look at a different model.

740 W PoE Budget Decides Fit

The 740 W PoE+ budget is the single figure that determines whether this unit can run all 48 ports at full 30 W simultaneously. If the connected devices draw less power, the switch covers them; if the total draw exceeds 740 W, a higher-budget switch is required.

Highlights

  • 48 PoE+ ports power phones and cameras directly
  • 740 W PoE budget supports dense device deployments
  • 4 SFP uplinks enable flexible fibre aggregation
  • 104 Gbps switching capacity handles heavy traffic loads
  • Layer 3 routing with OSPF and RIP simplifies network design

Questions about this item

Should I pick the 48-port PoE+ model or a smaller switch for my access layer?

This model gives you 48 RJ-45 ports with PoE+ and four SFP uplinks in a 1U rack unit, so you can power phones, cameras and APs while keeping fibre uplinks free.

What does the 104 Gbps switching capacity mean for daily traffic?

It means the internal fabric can move up to 104 Gbps of aggregated throughput, handling the 77.4 Mpps forwarding rate with 3.8 µs latency at 1 Gbps line speed.

How far can the four SFP uplink ports actually reach?

The four SFP slots accept standard Gigabit SFP transceivers; distance is set by the transceiver you install — short-range, long-range or extended optics all work.
