ST43402ND drives

ST43402ND drives have two I/O connectors as shown in Figure 16. Both of these I/O connectors (one for Port A and the other for Port B) are located on the I/O board. Figure 16 shows how typical I/O cables connect to the I/O board. You must use an adapter (part number 70935801) to terminate each I/O cable following the last drive in the daisy chain. Refer to information earlier in this section regarding the terminator power source jumpers and interface require- ments.
