What is the benefit of C22 power inlet connectors on the MX7000 chassis?

The correct answer is C. Allow for higher exhaust temperatures. C22 connectors (IEC 60320) are the high-temperature variant of the standard C20 connector, rated for operating temperatures up to 155°C versus the C20's 70°C limit - making them essential for dense chassis environments like the MX7000 where power inlets sit near hot exhaust…

Explanation

C22 connectors (IEC 60320) are the high-temperature variant of the standard C20 connector, rated for operating temperatures up to 155°C versus the C20's 70°C limit - making them essential for dense chassis environments like the MX7000 where power inlets sit near hot exhaust airflow. Option A is wrong because C22 carries the same amperage rating as C20 (16A/20A), providing no additional power capacity. Option B is a distractor that mistakes a technical specification for a broader product standard claim, and C22 is not universally standard across PowerEdge. Option D describes a different concept entirely - daisy-chaining or redundancy features are unrelated to connector form factor.

Memory tip: Think "C20 = standard temp, C22 = extra 2 degrees of heat tolerance" - the higher connector number signals higher temperature rating, not higher power.
