B.1 Accessing the Disk Array Administrator Using the RS-232 Serial Port

You can access the Disk Array Administrator software using the RS-232 serial port. You must use a

straight-through serial cable. You cannot use a null modem cable.

Configure the RS-232 port in your terminal emulator software using the following settings:

Set the communications parameters for the terminal program as follows:

Setting Value

Terminal Emulation VT-100 or ANSI (for color support)

Font Terminal

Translations None

Columns 80

Setting Value

Baud Rate 115,200

Data Bits 8

Stop Bits 1
