I removed three PowerConnect switches (Model 2324) and swapped them out with one Gigabit PowerConnect 2724 which is connected to our SnapGear SG560 Gateway Firewall/DHCP server.  I linked a second Gigabit PowerConnect 2748 to the 2724 unit.

The problem is; since making this swap and upgrade to a gigabit network, I have had quite a few network issues and it's actually running slower than before the upgrade!  My SnapGear SG560 quite frequently seems to choke up and requires a hard boot. (Power Cycle)  I did replace the SnapGear with a new one to no avail.  Question is, is there something I need to know about converting to a gigabit network or could this be a hardware issue?

Note:  I did have trouble with the 2748 (48 Port) PowerConnect and had it replaced once.  Today, I could not connect to it at all even though there was no issues with my SnapGear.  I had to Power Cycle the 2748 and then it became available again.  Note also, both PowerConnects are in Managed mode with no customization except that "Jumbo Frames" are turned off on both.

Any suggestions or has anyone else had similar issues with either the Dell PowerConnect 27XX series or SnapGear appliances?
