SERVSWITCH ELITE™
3.5 Initial Power-Up: Turning On the System
The first time you power up your ServSwitch Elite system, do it this way:
1. If you haven’t already done so, attach its power cord to the Switch and plug
the cord into a utility (mains) outlet.
2. Turn on your shared monitor(s).
3. Turn on the ServSwitch Elite by moving the power switch on its rear panel
from the
O
position to the
|
position. This switch is on the far right end of the
Switch’s rear panel, as shown in Figures 3-6 and 3-7 on page 24.
4. Power up all of the attached CPUs (if you’re not sure how, see the computers’
manuals).
The Switch has to be turned on before the computers because the computers’
keyboard, mouse, and video drivers send device-configuration requests/commands
out of the corresponding ports. If the Switch is already ON, it can generate
standard responses to these transmissions so that the PCs can boot normally even
though they aren’t physically connected to a keyboard, monitor, or mouse. If the
Switch is OFF, however, the PCs will probably either hang, crash, or boot into an
abnormal state.
NOTE
Later, once your ServSwitch Elite system is fully installed and
operational, the Switch will help your computers recover from power
outages. All of the computers attached to a Switch that are designed to
reboot themselves automatically (without user intervention) will do so
when power returns. The Switch generates responses to ensure that the
reboot is successful and that the Switch is ready to switch between
computers when regular operation resumes.
The Switch also does a few other things while it helps the PCs to boot:
1. It detects the device settings requested by the PC drivers. (You will probably
want to save these settings to the Switch’s NVRAM, so that it loads them
automatically each time it powers up—see Section 4.2.3. You can manually
change these NVRAM device settings later.)
2. It identifies the type of keyboard and mouse that are actually attached to each
of its consoles and puts them in their default states.
3. It displays revision information about its hardware and firmware on the
monitor screen.
