Network Problem

Last Modified: 2013-11-09
We have 7 3com 4200 switches were using solar winds to monitor our network all switch ports set to auto negotiage and pcs- Im thinking of changing these to full duplex.  Im using solarwinds orion to monitor our network but im not seeing any packet discards or anthying of the sort but in different locations randomly our switches are dropping network connection.  In one location we discovered a bad cable, in another we discovered a bad switch but on this bad switch when i perform continous pings and i get a request time out after about 40 replies but just this mourning another 3com switch went down for 15minutes and came back up by itself all our cables are cat6 what could be wrong one by one they keep going down.
