    Note: If you are on a version below Dell OS switch version 10.4.3.6 and / or ECS 3.4 this KB does not apply and the issue is detailed in the following KB ECS: xDoctor: RAP092: EX300: EX500: EX3000 slave-X or pslave-X is not communicating with Rabbit switch after reboot                                                           

 

 

Cause:

 

 

A switch configuration is missing on one or all ECS switches after a switch upgrade was done during the ECS 3.4 cluster upgrade.   
   
   
     
                                                           

 

 

Change:

 

 

This only impacts EX300 on 3.4 ECS as they use a different network card than the EX500 and EX3000 series.
