Switch Box Startup Behavior
It is important to turn on the switch box before turning on the computers
because when the servers boot up, their drivers send device settings to the
switch. During startup, the switch box unit does the following:
■
Identifies the mouse and keyboard and puts them into default states.
■
Switches to port 1 by default, and displays the number “1” in the status
flag displayed on the monitor. If the status flag default setting has been
changed to Names mode, the status flag displays the port name instead
of the port number. If a status flag is not shown on the monitor, make
sure the computer is connected and powered up.
Power up the system as follows:
1. Press the power switch located on the rear panel of the switch box to the
on (1) position.
2. Power up the computers.
Computer Startup Behavior
During startup, the computers send device settings to the switch box. The unit
then generates standard responses to these commands and allows the
computers to boot successfully without being physically connected to the
keyboard, monitor, or mouse. Once the switch is installed, you can save these
settings to non-volatile RAM (NVRAM). See Chapter 4 for additional
information.
Configuring the Switch Box
When you first turn on the switch box, no configuration is needed for basic
switching operation. To configure the unit to meet your specific needs, such as
assigning unique names for the computers or displaying the computers by their
assigned names or port numbers, see Chapter 4.
Unattended Reboot
After a power outage, each server connected to the switch box reboots (if
configured to do so) without operator intervention, when power returns. The
switch generates responses to ensure that the reboot is successful and that it is
ready to switch between computers.
