Using Internal Disks in Disk Array Configuration
For the installation of the RAID controller board, see "PCI Board" and the
manual that comes with the RAID controller board. The DISK access lamp on
the front panel of the server indicates the access status of the hard disk drive
connected to the RAID controller board. Before the access status can be
indicated, the LED connector on the RAID controller board and the DAC LED
connector on the system board must be connected through the LED cable
supplied with the server. The DAC LED connector is at the position shown in
the Figure 4-45 below. It can be connected in either direction.
