REMOVAL/REPLACEMENT INFORMATION

5.0 REMOVAL/REPLACEMENT INFORMATION
Figure 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. Refer to Figure 11.
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.
