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.
