Description

The Aruba 2920 is a modular, stackable Layer 3 managed access switch built for enterprise campus, SMB and branch networks that need PoE+ for phones, access points and cameras, with room to grow into 10GbE uplinks and stacking.

This 48-port model provides 44 fixed 10/100/1000 PoE+ RJ-45 ports plus 4 dual-personality 10/100/1000 PoE+ ports that share their slots with SFP optics. The PoE+ budget is 370W, switching capacity is 176 Gbps and forwarding rate is up to 130.9 Mpps. Two module slots take optional 10GbE SFP+ or 10GBASE-T uplink modules, and a separate stacking module slot supports up to 4 chassis. Routing covers RIP and Access OSPF, and the unit is 1U rack-mountable.

It accepts the 2920 series 2-port 10GbE SFP+ module, the 2-port 10GBASE-T module and the 2920 stacking module. The dual-personality ports support Gigabit-SX, LX, LH and 100-FX SFP optics. Redundant or upgraded power supplies are supported for a higher PoE budget.
