systems. The label at the base of the card cage identifies where the card(s) is located.
There is a soft start circuit on the card which allows for the Storage/Control I/O Module to be removed
and replaced while the system is running. This should only be done when the system contains redundant
Storage/Control I/O Modules, and when the module to be removed is in standby mode.
