Step 6: OPTIONAL. If you want the LED in your computer to light whenever there is activity on the SCSI bus, disconnect the LED cable from the LED connector on the motherboard and connect it to the LED connector on the host adapter. LED Cable from Motherboard 2-pin LED Cable LED Connector 1 1 on Host Adapter Pin 1 Step 7: Make sure that all your SCSI devices have been set with unique SCSI IDs from 0 to 6. (Refer to your device documentation for SCSI ID settings and instructions on changing the default settings.) Caution: AHA-2910C host adapters support only single-ended SCSI devices. Differential SCSI devices may be damaged if you connect them to the host adapter. Read the device documentation. Installing Internal SCSI Devices The SCSI devices inside a computer are attached to an internal SCSI cable. The last device on the cable must be terminated. Most internal SCSI devices have a jumper or switch that controls termination. Refer to the device's documentation on enabling or disabling termination. If you purchased your AHA-2910C as part of an Adaptec kit, you can use the 50-pin internal SCSI cable to connect up to two internal SCSI devices. Note: Before you begin, make sure your internal SCSI devices are not terminated. Step 1: Find the colored stripe on the 50-pin internal SCSI cable and then align it with Pin-1 on the host adapter's connector. Pin-1 is usually identified by a v, or "1" on the connector.
