I have a general question about networks and switches. My network wiring is newer (installed 4 years ago) and is all cat6. I have DSL, the modem goes into a SonicWall TZ210 (about 1 ½ years old.) That then is connected to an older Dell PowerConnect 2748 managed switch. Our server is a newer Dell PowerEdge T710 running Windows Server 2008 RS2. The switch is set to default and the managed light is green. From there most of the ports are home runs. The acceptation are four small Linksys EZXS55W 10/100 switches that are needed because there are not enough ports in those areas. The problem is at time it seems that the network lags. We are a small commercial printer with about 22 PC’s and about 5 Macs and a number of large copiers. Our data file that we are moving or printing are large.
My question is two fold. I think I understand that an end device with a 10/100 NIC card would not slow the entire network down, but do the Linksys EZXS55W 10/100 switches slow it down? Second, am I doing my network a disservice by using the older Dell PowerConnect 2748 managed switch vs. a newer more costly switch? Not that familiar with the inner workings of managed switches and how to utilize them.
Thanks ahead for any info or easy to read links!
