RS-232 Service Port
Located on the left side of the RAID Controller face plate you will find an RS-232
serial port labeled Service Port. This serial interface uses a USB-type connector
and requires a custom USB to DB-9 cable. It provides the means to use a terminal
or terminal emulation to access the firmware based utility program. The onboard
software allows monitoring of enclosure components via SES processes,
performing firmware updates, maintenance, and drive slot assignment.
Below are the pin signals for this connector. The data communication cable is
provided with the enclosure. Should the need arise to test the cable or replicate
it, the pin out information for the interface and cable are provided below, and on
the following page.
CAUTION:
This is not a standard USB connection. Do not connect a standard
USB cable to the Service Port.
