A.5 Connecting to the Diagnostic Serial Port
The DSN-5210 series and DSN-5410 SAN arrays have a 115.2 Kbps RS-232-C stereo mini-jack
connector on the right side of the rear panel (see Figure A-5). Using this port, you can:

Reset the array to factory default settings (this deletes all custom settings, including all
accounts you may have set up, except the default admin account)

Reboot or shutdown the array

Set the out-of-band port configuration
This port also lets you monitor the array’s power-on self test.
The arrays come with a cable for connecting a computer or server (PC) to the array’s
diagnostic port. The cable has a stereo mini-jack connector on one end that attaches to the
array’s diagnostic port and a DB-9 connector on the other end that attaches to a PC.
The PC must have a terminal-emulation program (such as HyperTerminal) installed. The
program should be configured as follows:

Baud rate: 115,200 bps

Data bits: 8

Parity: None

Stop bits: 1
