2.6 Connecting Devices

You can connect a total of 30 SCSI devices to the ASUS LS99 LAN/SCSI card, with up to 15 devices on each SCSI channel. Before connecting devices, be sure to review 2.5 Setting Up SCSI Devices.

2.6.1 Connecting Internal Ultra160 and Ultra2 Devices

A special 68-pin LVD cable is provided to connect internal Ultra160 or Ultra2 SCSI devices. If your cables are not marked, you can identify most LVD cables as having twisted pairs of the flat ribbon cable between the device connectors.

The ASUS LS99 LAN/SCSI card has two separate Ultra160 SCSI channels, as shown in 2.1 ASUS LS99 LAN/SCSI card Layout. Each channel has an internal LVD/SE connector to which you can connect internal SCSI devices. Follow these steps to connect your internal Ultra160 and Ultra2 devices.

NOTE: We recommend that Ultra160 and Ultra2 SCSI devices are kept on a separate SCSI channel from Ultra SCSI devices. This allows the newer Ultra160 and Ultra2 SCSI devices to transfer data at their maximum speed.
