Blades GbE2 Switches Redundancy

[PProcopi_1]

I have GbE2 Switch in ours Blades enclosure. I have on both switches VLAN1, and enable STP. I want one cable from switchA (cableA-Port19) and one cable from switchB (cableB-port19) to connect to ours network for redundancy. When i disconnect cable from switchB ( cableB-port19 ) i can ping both switches and Blades servers. When i connect again cableB i can ping blades servers and switchA but i get 6-8 time-out from switchB and then works OK. When i disconnect cable from switchA (cableA-port19) i get 14-18 time-out from servers and switches, and then i gets replys. When i connect agian cableA i get 14-18 time-out from servers and switches and then works OK. ANY HELP?????

I think that your problem is not properly configuring STP.
