RAID Controller Card
Installing a RAID Controller Card
Follow these general guidelines when installing a RAID controller card. For specific instructions, see the documentation
supplied with the RAID controller card.
CAUTION: Before you perform this procedure, read the safety instructions in your System Information
document.
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System
Information document.
NOTICE: The integrated RAID controller in your NAS system is activated when you receive it. To avoid loss of data, do
not disable the RAID controller.
1. Unpack the RAID controller card, and prepare it for installation.
For instructions, see the documentation accompanying the card.
2. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
3. Remove the cover (see " Removing the Cover ").
4. Install the RAID controller card (see " Installing an Expansion Card ").
5. Connect the external SCSI devices to the card's external connector on the system's back panel.
If you are attaching multiple external SCSI devices, daisy-chain the devices to each other using the cables shipped with
each device.
6. Replace the cover (see " Removing the Cover ").
7. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
8. Install any required SCSI device drivers (see "Installing and Configuring SCSI Drivers" in the User's Guide).
9. Test the SCSI devices.
Test a SCSI hard drive by running the SCSI Controllers test in the system diagnostics.
Installing the SCSI Cable Strain-Relief Bracket
CAUTION: Before you perform this procedure, read the safety instructions in your System Information
document.
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Ensure that the system is pushed back as far as possible in the rack.
NOTE: To use the strain-relief bracket, only two SCSI cables can be connected to the system at a time. The cables
cannot be stacked, one above the other; they must be either side-by-side or placed diagonally to each other.
3. Connect the SCSI cables to the system before connecting the I/O cables.
4. Install the strain-relief bracket in the back of the system.
a. Insert the ends of the three long portions of the strain-relief bracket into the three matching holes in the rail
bracket (see Figure 4-23 ).
b. Secure the captive thumbscrew to the back of the system (see Figure 4-23 ).
