Definitions for "Cold Swap"
Replacement of a hard drive, fan, power supply, etc. when the RAID is powered off, or a hard drive kept ready in case of an array hard drive failure. All RaidWeb units support hot swap-no power down necessary.
A cold swap requires that you power down the system before replacing a defective hard drive in a disk subsystem.
Power must be switched off before the removal or insertion of a component.
