Installing the HostRAID Controller
This section describes how to install your HostRAID controller into your computer cabinet.
1Turn off your computer and disconnect the power cord. Open the cabinet, following the
manufacturer’s instructions.
2Select an available PCI or PCI-X expansion slot and remove
the slot cover, as shown at right. (see page 12.)
For the best performance, use the available 64-bit slot that’s
compatible with your HostRAID controller.
Caution: Touch a grounded metal object before
handling the HostRAID controller.
3As shown at right, insert the HostRAID controller into the
PCI or PCI-X expansion slot and press down gently but
firmly until it clicks into place. When installed properly, the
HostRAID controller should appear level with the
expansion slot.
4Secure the bracket in the PCI slot, using the retention
device (for instance, a screw or lever) supplied with your
computer.
5Connect your computer’s disk activity LED cable to the
LED connector on the controller (see page 12).
Ensure that the positive lead of the LED cable (usually a red
wire or a wire marked with a red stripe) is attached to pin 1.
6Optional—Connect your HostRAID controller’s I2C
connector (not available on all models) to an I2C
connector on an internal backplane or enclosure, using an
I2C cable.
7Install your disk drives, following the instructions on page 24.
