A connector (J06) at the back of the drive accepts the I/O cable that connects it to the system. The daisychain cable is a continuous unshielded cable having one connector for each drive it connects to.

Refer to the reference manual (publication 83327640) for guidelines on I/O cabling. These guidelines discuss the use of unshielded cabling inside cabinets and shielded cabling running between cabinets. They also contain information about constructing continuous daisychain cabling (including part numbers for the required cabling components).

Table 5 on the following page shows the pin assignments and signal names for the unshielded single-ended I/O cable. Table 6 shows the pin assignments and signal names for the unshielded differential I/O cable. Detailed information about interface lines is provided in the reference manual.
