D-PEMX-DY-23 · Question #81
In addition to one compute sled, one management module, and one IOM, what is the minimum required HW configuration on the PowerEdge MX7000 to POST?
The correct answer is C. 2 power supply units. Two power supply units are required because the PowerEdge MX7000 chassis enforces a minimum power threshold at boot - a single PSU cannot deliver enough power to satisfy the chassis controller's requirements for POST, even with just one compute sled installed. Options A and B…

Explanation
Two power supply units are required because the PowerEdge MX7000 chassis enforces a minimum power threshold at boot - a single PSU cannot deliver enough power to satisfy the chassis controller's requirements for POST, even with just one compute sled installed. Options A and B are identical distractors (both state 1 PSU), making them both wrong for the same reason: one PSU is insufficient to bring the system to POST regardless of how the choice is labeled. Option D (3 PSUs) exceeds the minimum and while valid for redundancy in production, it is not the minimum required. A helpful memory tip: think "MX = Minimum 2" - the MX7000 needs at least 2 PSUs to even begin booting, before you worry about N+1 redundancy.
