A newly deployed stack with servers, network switches, a KVM $($Key$,$ Video, Mouse$),$ storage unit, and uninterruptible power supplies has just been fully cabled.

After powering on the stack, there seems to be a network connectivity issue between the switch and servers.

What is the best approach when trying to resolve this type of network issue?
