There is no workaround for this as CMCNE allows only one ESRS gateway to be configured. As long as all switches are discovered in CMCNE and assigned to the EMC call home center, there should be no issues.
    We are setting up a connectrix manager that supports several sites for a customer.  Each site has its own esrs server but when we setup call home in connectrix manager it appears i can only have one EMC esrs call-home destination.  Is there a way around this or will we need to have all the switches across the multiple sites use one sites's esrs ip for call-home to DellEMC.  Will this cause any issues with switch registration/support when they dial-home.
Is is possible to setup multiple EMC (ESRS) call-home destinations in CMCNE?
