I've been running 8 of these switches (6 x 6248 and 2 x 6224) for over 14 months. We've had zeros issues and 100% uptime. The other reviews on dell.com giving it a low mark are probably written by a newb who didn't know what they were doing. The overall quality and value are unmatched when comparing the 62XX series of switches against similar models from Cisco and HP. You'll pay 2 or 3 times as much.
While not using every feature this switch has to offer, we do use many of them, some of them "advanced". We currently use them as upstream routers, VRRP, OSPF, and spanning tree. It'd be nice if they could support BGP, but if you need BGP then you probably need a different product anyway. They don't support spanning tree per vlan, so again we had to make sure our ISL links between switches only carried the VLAN traffic we actually needed connected. Only other issue we had was getting some of the administrative functionality to run -- e.g. enabling SSH access. A few posts on the Dell forums and we had help in a couple hours.
Overall, super happy with our purchase and glad we didn't spend the extra cash on a different vendor.

Review 3 for PowerConnect 6248
Good Mid Level Switch
PostedOctober 19, 2010
Yes, I would recommend this product
I agree with the earlier poster that one mistake can bring the stack down with a long reboot time which will bring havoc on your network.
That said I've been running 4 of these switches for almost 3 years with limited difficulties. The throughput is very good even at high loads and they function great stacked as my entire office network infrastructure. I have to admit that the management documentation and features are pretty tough to use and haven't provided a ton of value to me.
Over all though its a good buy for the price if you don't need the advanced feature sets.

OK for basic networking, not for the datacenter
PostedApril 6, 2010
No, I do not recommend this product.
These switches perform well as basic switches. They start to fall seriously short when used in a datacenter. They have a number of know issues such as: SSH can cause an entire stack to reboot, the SNMP data is lacking, the MIBs are incomplete/incorrect, and some features such as BPDU guard don't seem to work at all.
The latest firmware is over a year old, with no update/fixes in sight.
The limit of 8 LAGs is too small if you have a bunch of servers you want to LAG together across a stack.
If you can afford it, get a better switch.
Feature and capability wise, they're a good buy, but the firmware is just too buggy and unstable.
Bottom line, if any random user can crash an entire stack of switches simply by attempting an ssh connection (no account required), and there isn't a fix in sight, then you've got a problem.
