What feature allows hot swapping of components in certain Dell products?

Hot swap capability is a specific feature that enables users to replace or add components to a system without needing to power down the entire machine. This feature is particularly valuable in environments where uptime is critical, as it allows for the seamless maintenance of hardware components such as hard drives, power supplies, and other peripherals.

In certain Dell products, the implementation of hot plug capability means that users can ensure continuous operations while performing upgrades or repairs, thus minimizing disruptions. The technology relies on proper design and integration at both the hardware and firmware levels to recognize new components as they are inserted and to manage their interaction with the system without needing a reboot.

The other options lack the specific context of enabling component replacement without powering down. Modular design refers to the overall construction philosophy that allows for components to be easily replaced or upgraded, but it does not inherently imply that they can be swapped while the system is active. Dynamic readjustment typically relates to the automatic adjustments of system resources rather than physical component changes. Self-healing technology is about the system’s ability to recover from failures rather than the capability to physically swap parts without interruption.
