Data bus widths

These drives have a wide (16-bit) SCSI data bus. You can use these drives on a non-wide (8-bit) data bus if you provide proper termination to the upper eight data lines. This is often referred to as providing “high-9 termination” (the other bit is for parity).

The following table lists the maximum cable lengths and number of devices using single-ended and LVD I/O circuits.

Providing adequate cooling

The enclosure design must ensure adequate cooling for the drive. The maximum ambient temperature allowed is 50°C.

The drive’s product manual (83329471) describes how to evalu- ate the air-flow design. The evaluation consists of ensuring that the case temperature of certain critical components remains within acceptable limits during drive operation.

Figure 2 shows two design approaches with one or more fans used to generate air flow. The air-flow patterns can be created
