PowerEdge MX Installation Instructions

ertificate expires, if there is a network event such as a reload or a flap, the VLT peers and SFS cluster members will cease
to communicate. As a result, network traffic will be affected. See Section 3, Preparing for an upgrade in the Dell EMC

NOTE: OS downgrade or rollback is not recommended for MX-series switches.
