Managed Layer 2 Gigabit Ethernet switch
Auto-voice VLAN automatically assigns Voice over IP (VoIP) traffic to a voice-dedicated VLAN, optimizing this delay-sensitive traffic
No need to configure the switch if default settings are acceptable
If more control desired, the completely redesigned switch interface allows even novice users to quickly and confidently configure the switch
VLANs segment the network by grouping users based on their data or traffic requirements, making the best use of available bandwidth
With LACP link aggregation, automatically group ports together to form an ultra-high-bandwidth trunked connection to the network backbone and help prevent traffic bottlenecks
IEEE 802.1X network access control provides standards-based security combined with local authentication
MAC- and IP-based ACLs enable network traffic filtering and enhance network control
Rapid Spanning Tree Protocol (RSTP) support improves network compatibility, scalability and availability
IGMP snooping and multicast filtering optimizes network performance

N/A 12/31/2008 5:03:32 PM Tech Level: 5/5 Ownership: 4/5	Rating: 2/5 Pros: Nice interface, black color, good number of ports. Cons: I can't get VLANs to work properly. It won't let me modify VLAN 1 to let it connect to the tagged VLAN1 packets coming from my other switch, meaning I either need to make everything VLAN2 (which causes problems) or forget about it. Other Thoughts: 3com SuperStack switches are better, Baseline REALLY means Baseline. 1 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
Mike Connor 7/31/2008 4:09:52 PM Tech Level: 5/5 Ownership: 4/5	Rating: 5/5Great switch, no headaches Pros: Does everything it claims and is very easy to set up. Seeing throughputs at 50 to 80 MB/sec, which is all the faster the hard drives are. Cons: I suppose it's loud, so the home user may not like it. Other Thoughts: You can't hear it over a typical server. 2 out of 2 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
N/A 6/6/2008 1:02:44 PM Tech Level: 5/5 Ownership: 2/5 Verified Owner	Rating: 1/5Don't buy unless it is going in a soundproof room. Pros: Good specs, slightly above average for a L2 managed router. Cons: Unit has two fans that are ridiculously loud. Fans also have a psychosis inducing high frequency harmonic that creates uncontrollable urge in humans to unplug the unit. Seriously. Other Thoughts: RMA's item b/c fan noise and harmonic whine. It is just not possible to live in the same room with this item. 3 out of 5 people found this review helpful. Did you?

N/A 4/24/2008 2:41:15 PM Tech Level: 4/5 Ownership: 4/5 Verified Owner	Rating: 5/5Solid Pros: Excellent, simple setup, fast transfer speeds. Cons: N/A Other Thoughts: It just works and well at that. Web based configuation is simple to understand and easy jump into. 1 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
DelayedACK 4/6/2008 8:14:19 AM Tech Level: 5/5 Ownership: 3/5	Rating: 4/5Good value SMB/home switch for a closet or garage Pros: Great switch for a small or medium biz, or home. 24 ports of wirespeed Gigabit Ethernet with support for: Spanning Tree, SNMP + syslog, statistics + diagnostics, VLAN + QoS support, 802.1x + RADIUS + ACLs, and more. Good web based admin too. Std AC power cable (no power brick). Cons: I agree with the other reviewers. Two small side-mounted fans are louder than they need to be. Put this puppy in a garage or wiring closet. :) Other Thoughts: Hard to find another switch with these qualities/features for the same price. If 3Com would just replace the fans with quiet ones, this would be a killer. Still very happy with it. 3 out of 3 people found this review helpful. Did you?

KMC 11/14/2007 7:55:24 PM Tech Level: 5/5 Ownership: 4/5	Rating: 4/5Great edge switch for small environments Pros: I am a network admin for a small hosptial. I chose this and the 2948-SPF to replace the old 3300 superstack II's. All in all they both are great units, where else can you get all these features at 1Gb to the client for under $1500 per switch??? Cons: One thing to watch out for, this and the 2948-SPF DOES NOT SUPPORT automatic VLAN propogation. But I guess thats what I get for not buying $2k switches... They still work great after manually setting up the vlans, its just lame that I have to do that across 18 edge switches... Other Thoughts: I think 3com did a great job putting these features in the reach of small budgeted companies to improve their network infrastructure. So, if you want a great cheap switch get this one, if you want ALL the bells and whistles of a enterprise switch, spend $2k each on a 4000 series or go Cisco. 2 out of 2 people found this review helpful.

Other Thoughts: I'll try a different brand next time. 1 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
