Hi,  I've taken your advice and remove one cable at a time. 1 - xg1: RBYT:3855a050 RPKT:dd2b08c TBYT:a5c977be TPKT:a135eb0 RFCS:0 RFRG:0 RJBR:0 RUND:0 ROVR:0 TFCS:0 TERR:0 1 - xg2: RBYT:7a281363 RPKT:645786e TBYT:9002bce8 TPKT:c4fe455 RFCS:64 RFRG:3e RJBR:0 RUND:0 ROVR:0 TFCS:0 TERR:0 2 - xg1: RBYT:9e5bf4f5 RPKT:39a7828 TBYT:8a962446 TPKT:a2eef6d RFCS:39 RFRG:1a3 RJBR:0 RUND:0 ROVR:0 TFCS:0 TERR:0 2 - xg2: RBYT:a5c97db4 RPKT:a135eb5 TBYT:3855ce02 TPKT:dd2b095 RFCS:0 RFRG:0 RJBR:0 RUND:0 ROVR:0 TFCS:0 TERR:0  No matter what cable i remove or plugin i get erro on   1 -xg2and 2-xg1  (i've even use a new cable all together for both ports - 1M or 3M)  Still same error pumping out of 1-xg2 and 2-xg1  Hence i decided to bite the bullet and swap out the module card itself. (I have a 2 unconfigured 6224 laying around, since it's the same 6200 series i swap the cards)  Since then...  no error "Show stack-port counter"  =  shows 0 error for everything "Show stack-port diag" = show 0 for everything   A side question,  since swapping out the module for both stacks.  I notice that all my configuration is gone(meaning my switch ask me to whether i want to perform the Wizard). Is that expected ?  
I'm configuring a 2 PowerConnect in stack mode.  I can't seem to resolve this error - Recieved Frame Check Sequence Errors. Both stacks are in the lastest firmware version 3.3.4.1. Physical connections are tight.   [IMAGE] [IMAGE]  Anyone can help ?
