System component description
Table 19 lists the SP serial RS-232/EIA 232 (micro DB-9) pin signals used on the
connector.
SP null modem (micro DB-9 to DB-9 serial) cable
The cable connecting the SP 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 27 shows an example of an SP
to PC (service laptop) cable.

Serial RS-232/EIA 232 (micro DB-9) connector (socket) for SPS
management
The back of the Block and File (Unified) VNX5500 platform SP includes a second standard
serial RS-232/EIA 232 interface (micro DB-9) socket connector (labeled with a symbol
depicting a battery on the left) to connect to the SPS management port (RJ-12). Notice the
orientation of the pins shown in Figure 28.
Note: The included cable has a micro DB-9 connector (pins 1, 3, and 4 are used) on one
end and an RJ-12 modular jack adapter (pins 1, 7, and 8 are used) on the other end. The
RJ-12 modular jack adaptor end connects to the RJ-12 modular jack connector on the SPS
(Figure 14 on page 25).
