What type of power cord connects to the PSU side of a PowerEdge MX7000?

Question

Options

• AC13
• BC15
• CC15
• DC21

Explanation

D is correct because the Dell PowerEdge MX7000 chassis PSUs use C21 receptacles - the high-temperature, high-current IEC connector rated for 16–20A at up to 120°C, which is required to handle the thermal and power demands of a high-density modular chassis.

Why the distractors are wrong:

• C13 (A) is a standard 10A low-current connector used for lightweight devices - far underpowered for a chassis PSU.
• C15 (B/C) is the high-temperature variant of C13, still limited to 10A - better for hot environments but not enough current capacity. (Note: C15 appearing twice in the choices suggests one option was likely meant to be C19, the standard 16A connector - which is still wrong because the MX7000 requires the high-temp variant.)
• C19 would be the close wrong answer - same current rating as C21 but rated only to 70°C, insufficient for the MX7000's operating environment.

Memory tip: IEC high-temperature variants are always the connector number +2 - C13→C15, C19→C21. For a massive chassis like the MX7000, think "big chassis = big power + big heat = C19+2 = C21."
