HP Aruba 2920-48G PoE+ 48 Port PoE+ Gigabit Switch J9729A
COMES WITH J9733A Stacking Module and is fitted with 1 x 575W Power Supply

The HP Aruba 2920-48G-PoE+ Switch (J9729A) is a Switch provides security, scalability, and ease of use for enterprise edge, SMB and branch office networks. A powerful ProVision ASIC delivers low latency, more packet buffering, and adaptive power consumption. This layer 3 switch series supports modular stacking, 10GbE, PoE+, static and RIP routing, Access OSPF routing, Tunneled Node, ACLs, sFlow, and IPv6. There are no software access licensing requirements for this switch, so it is ready to deploy and integrate

Key Features

Aruba Layer 3 switch series with stacking, static& RIP routing, IPv6, ACLs, and sFlow
Advanced security and network management tools with Aruba ClearPass Policy Manager and Aruba AirWave
Modular 10GbE uplinks (SFP+ and 10GBASE-T) and upgradeable power supply option
Simple deployment with Zero Touch Provisioning and cloud-based Aruba Central support
Ready for the software defined network with REST APIs and OpenFlow support

The Aruba 2920 Switch Series provides cost-effective pay as you grow modular stacking with a 2-port stacking module, support for up to four 10GBASE-T (or SFP+) uplinks and upgradeable power supplies so your network can quickly scale when needed. The robust Layer 3 feature set requires no licensing and includes a limited lifetime warranty.
