What does the black strap on the power supply handle specify?

  1. PSU
  2. NAF
  3. RAF
  4. Spare PSU

Answer(s): B

Explanation:

Understanding the Black Strap on the Power Supply Handle
Server Components (26%)
Identify power options and redundancy features, thermal features, and liquid cooling

Explanation of Power Supply Straps
Dell PowerEdge servers often use black straps on power supply units (PSUs) to indicate certain attributes of the PSU. The color of the strap can help identify specific features or categories of the power supply.

What Does "NAF" Mean?
NAF stands for Non-Redundant, Auto Failover.
This indicates that the PSU is part of a non-redundant configuration, but it is capable of automatic failover in the case of power loss.
This is typical in systems with multiple PSUs, where each PSU can take over if the other fails.
Why Not Other Options?
Option A: PSU
The strap does not indicate that the device is just a PSU; rather, it indicates a specific feature of the PSU.
Option C: RAF
RAF stands for Redundant Auto Failover, which is not the correct feature indicated by the black strap.
Option D: Spare PSU
The strap does not indicate that the PSU is a spare unit.

Conclusion
The black strap on the power supply handle indicates that the PSU is NAF (Non-Redundant, Auto
Failover). This means it is part of a non-redundant system but capable of automatic failover.
