During the software platform installation procedure, you have the option
of configuring the COM1 serial port (in Linux, this is referred to as ttyS0)
for console login during system runtime. The configured serial port has
the following characteristics:

•

7-bit characters with even, odd, none, or space parity, and 8-bit
characters with no parity are supported

•

Only COM1 (ttyS0) is supported

•

Terminal emulation is VT100

•

The user has the option of configuring either a 9 600 or 19 200 baud
rate

Connect a physical monitor or a KVM switch to the video port. This
provides the physical KVM console. Nortel does not provide a KVM for
use with this product.

Connect a USB keyboard, or a KVM switch, to one of the USB ports to
provide a physical KVM console. A USB keyboard connected through
a KVM switch can sometimes become unresponsive while switching
consoles at the KVM keyboard. If this occurs, typing

CTRL+Q

toggles the

flow control signals to restore keyboard communications with the server.
