Upgrading Your System 4-35
LED Relay Cabling
To indicate disk access status in a disk array configuration, connect the
LED relay cable connected on the system board connector to the HDD
LED connector of the disk array controller. See Figure 4-34.
Note:
To switch the internal hard disk drives into a disk array
configuration by installing a disk array controller into the full-height riser
card, connect the SCSI cable to the disk array controller before installing
the riser card into the system board.
The LED relay cable is free from polarities. Either end of the cable can be
connected to either of the HDD LED connectors
.
IMPORTANT:
If a card is installed in a slot below the one containing the
AcceleRAID 160 disk array controller, the LED relay cable is connected to the
disk array controller. This prevents the cable connector from touching the card in
the lower slot.
