SKU CH-4PD0-S5KSD

A managed 48-port Layer 3 switch with 44 autosensing 10/100/1000 RJ-45 ports and four combo Gigabit SFP slots for modular uplinks and stacking

  • 44 autosensing RJ-45 ports connect wired devices at up to 1 Gbps
  • 4 combo SFP slots add fibre uplinks without losing copper ports
  • Layer 3 routing with static and RIP protocols directs traffic between subnets
  • Modular stacking module lets you scale the stack to four units
  • ProVision ASIC delivers low latency and adaptive power consumption

HP Aruba 2920-48G Switch

The HP Aruba 2920-48G is a managed Layer 3 switch built for enterprise edge, SMB and branch office networks. It provides 44 RJ-45 autosensing 10/100/1000 ports and four combo Gigabit SFP slots in a rack-mountable chassis. The ProVision ASIC delivers low latency and adaptive power consumption for wired and wireless convergence.

Sustained Load Behaviour

A powerful ProVision ASIC delivers low latency and more packet buffering during continuous traffic flows. Adaptive power consumption adjusts draw based on actual utilisation rather than peak rating. Modular stacking and upgradeable power supplies allow the platform to scale without service interruption when demand grows.

Upgrade Context

This switch replaces older fixed-configuration edge switches that lack modular 10GbE uplinks, stacking or PoE+ flexibility. The jump is worth it when a network needs pay-as-you-grow stacking, static and RIP routing, Access OSPF, ACLs, sFlow and IPv6 support managed through Aruba ClearPass, AirWave or Central.

Highlights

  • 44 autosensing RJ-45 ports connect wired devices at up to 1 Gbps
  • 4 combo SFP slots add fibre uplinks without losing copper ports
  • Layer 3 routing with static and RIP protocols directs traffic between subnets

Questions about this item

How much power does the Aruba 2920-48G draw when all 48 ports are active all day?

The ProVision ASIC provides adaptive power consumption, so draw scales with actual traffic rather than staying at a fixed maximum.

What cabling or modules must I already have to use the four combo SFP uplinks on this switch?

You need compatible SFP transceivers and the matching fibre or copper patch cables for the link distance you require; the switch accepts standard SFP modules in those four ports.

Will the 10/100/1000 RJ-45 ports on this 2920-48G negotiate correctly with older 10 Mbps devices I still use?

Yes, the 44 autosensing RJ-45 ports negotiate down to 10 Mbps half or full duplex, so legacy endpoints connect without manual configuration.
