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.
