Installation
See "PCI Board" for the installation of a disk array controller.
IMPORTANT:
A riser card is designed for installing only low-profile PCI boards or
full-height PCI boards. Before installing a PCI board, make sure of the
card specification.
If a disk array controller is installed in two PCI slots "1C" (for a low-
profile PCI board) and "1B" (for a full-height PCI board), the system is
unable to start through the disk array connected to the disk array
controller installed in PCI slot "1B."
In the following instance, the provided LED relay cable cannot be
connected and the access lamp that indicates the status of access to the
internal hard disk drives does not function:
The internal hard disk drives are used in a disk array configuration by
installing the disk array controller on the riser card dedicated to low-
profile PCI boards.
In the following instance, the provided LED relay cable cannot be
connected and the access lamp that indicates the status of access to the
internal hard disk drives does not function:
The disk array controller is installed, and the internal hard disk drives
are connected to channel 1 of the disk array controller. To solve the
above problem, connect the internal hard disk drives to channel 0.
Removal
Remove a disk array controller board in reverse order of the installation steps.
