A.6 Connecting to the Diagnostic Serial Port
The DSN-4X00 primary array includes a 115.2 Kbps RS-232-C stereo mini-jack connector on
the left side of the rear panel (see Figure A-6). Using this port, you can:
Reset the array to factory default settings (this deletes all custom settings, including
iSCSI initiators, network portals, LAG’s, advanced system settings, advanced volume
settings, and all user accounts you may have set up, except for the default
admin
account)
Reboot or shutdown the storage array
Set the out-of-band port configuration
This port also lets you monitor the array’s power-on self test.
The DSN-4X00 comes with a special serial cable for connecting a computer or server (PC) to
the array’s diagnostic port. The cable has a 3-mm 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.
