Removal and Replacement Information
Figure 4-11 shows the location of the Storage/Control I/O Module cards in the rear of the VCO system. The card is located in slots 3 to 4 in nonredundant systems, and in slots 3 to 4 and 5 to 6 in redundant 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.
