HP V1910 Series devices are smart-managed voice-ready fixed configuration Gigabit Layer 2+ switches designed for small and midsize businesses looking for an easily managed yet advanced networking solution. The Series has five models - V1910-16G, V1910-24G, V1910-48G, V1910-24G-PoE (170W), and V1910-24G-PoE (365W) each with 10/100/1000 ports and an additional four true Gigabit SFP ports. These smart-managed switches deliver advanced features for environments not requiring centralized administration. They allow network operation to be optimized using an intuitive web-based management interface. Advanced features include: Layer 3 static routing; Access Control Lists for enhanced security, auto-voice VLAN; QoS traffic prioritization; LLDP; Spanning Tree Protocols; and Power over Ethernet models. The switches are supported by a 3-Year Warranty.

Actually a relabeled 3Com Baseline Plus Switch 2900G - 28 port . HP acquired 3Com last year and they have relabeled the 3Com Baseline Plus Switch 2900G - 28 port as the HP V1910G-24. It is a very capable switch, with excellent VLAN support, full SNMPv3, and some very handy built-in physical cable test capabilities. At this price (under five hundred dollars), this device is a real bargain. It still runs the 3Com firmware, and has a few unusual features (such as the 3Com "captcha" web management login security, which you can't disable). But there is no other switch as powerful as this one for the money.

nice access switch . We actually replaced all of our Cisco 2940 with Hp V1910 switches. As already told these ones are relabeled 3com 2900 series switches. 1 of the delivered of about 35 switches was actually DOA.
One hint to all of you, always update all of your devices with the latest firmware when arrived. All of our devices had one of the first releases uploaded.

We also tested the HP 2910al series first. As we don't need 10Gbit module slots, comparing the supported protocols and finally the price, we took the 3com ones, although the 3coms have to be managed over web interface, as the cli is somehow limited and warranty is "only" 3 years.

Well, let's see in some weeks, months, years, whether this was a good or bad idea.

Great feature set some issues for me . At first I was very pleased with this switch. It has a great list of features for the price. Hard to touch anything else with routing capabilities in this price range, along with VLAN's, QoS, link aggregation, jumbo frames and more.

So, now for the problem. I saw about a 25% packet loss ratio going to one device, which happened to be my most important system. A high end storage system, where high speed connectivity is critical. I was using NFS and iSCSI connectivity through this switch, but the hosts got terrible timeouts, due to packet loss. Everything was directly connected through this switch, with no routing, flat layer 2.

How do I know this switch was part of the problem? Because I moved a few hosts and my storage device to a little 5 port 1 GbE hub, and no problems. So, this switch is partly to blame. I tried troubleshooting, but couldn't find the problem. BTW, HP support is pretty good, so that is a nice benefit. Since I was at 29 days, I decided to return this switch rather than fight through and diagnose further.

So, others may not experience this problem, in which case this is a great switch. For me, issues, but good support.
