    • Updated the network prerequisites with the required IP address counts for MNNVL racks.
    • Clarified the per-node breakdown: three IPs for switch management and NVOS, plus one IP for the power shelf.

Walkthrough

The network prerequisites documentation adds the required per-node IP accounting for MNNVL racks, covering the switch BMC, NVOS instances, and power shelf PMC.

- Line 24: Clarify the table row’s allocation scope by indicating that the three
switch BMC/NVOS addresses are per node, while the single power shelf PMC address
is per rack; state the total as 3N + 1 IPs for a rack with N nodes rather than
implying 4 IPs per node.
