4.2 Serial Port Access

The Diamond-VT provides remote service operations over the RS-232 serial port using standard terminal emulation software available with most systems.

The Diamond-VT supports service operations over the RS-232 serial port using standard terminal emulation software available with most systems.

1Connect a DB-9 null modem serial cable between the port marked RS-232 on the front of the Diamond-VT and one of the computer’s serial ports. A gender changer or DB-9 to DB- 25 converter may be needed depending on the cables you are using. The cable must be no longer than three meters.

2Boot the computer used to manage the Diamond-VT.

3Start a terminal emulator program such as Windows HyperTerminal. Set the emulator to use the COM port with cable attached, then the following settings

• 115200 baud

•8 bit ASCII

•no parity

•ASCII terminal type

•1 stop bit

•flow control none

•echo typed characters locally

4Turn on the Diamond-VT. Upon successful power on and diagnostics, the unit should display the POST (power on self test) information found in Exhibit 4.0-1 on page 16.

5You should now be in the Command Line Interface mode. To see a list of available commands, type help at the Ready prompt or refer to this manual’s Index.

6Use the Command Line Interface to configure the unit as a RAID Level 10 or RAID Level 5 array with zones and/or Hot Spare sleds as described later in this manual.
