Storage processor null modem (micro DB-9 to DB-9 serial) cable — The cable connecting
the SP management module to the PC or service laptop is a micro DB-9 cable (plug) to
serial DB-9 (socket). It has a micro DB-9 plug (SP side) on one end and a serial DB-9
socket (PC or service laptop side) on the other end. Figure 19 shows an example of an SP
