3.2.5.A Initial Steps
1A.
2-port model (KV5002MA-R2):
Making sure that the connected CPUs and any
connected submasters are OFF (powered down), take the output cord of the
ServSwitch Ultra’s power supply and plug its 5-pin DIN male connector into
the power jack on the rear panel of the Switch. Plug the power supply’s input
cord into a working outlet.
1B.
Other models:
Making sure that the connected CPUs and any connected
submasters are OFF (powered down), take the ServSwitch Ultra’s power cord
and plug its IEC 320 female connector into the power inlet on the rear panel
of the Switch. Plug its other end into a working outlet.
2. To power up the ServSwitch Ultra, push the ON/OFF button on its front
panel (if it’s a 2-port unit) or move the ON/OFF switch on its rear panel to the
“|” (ON) position (if it’s another type of unit). The Switch should boot
normally, but if the unit’s firmware has become corrupted—probably as the
result of a firmware upgrade going wrong—it will display this message on the
attached monitor:
Kernel is bad, load new kernel through serial port
If you see this, you will need to download correct firmware to the unit as
described in
Section 4.4.3
, starting at the point at which the unit is ready to
receive the file at 9600 baud (9600 bps). (In this case, you
must
download the
file at 9600 bps.)
3.2.5.B Remaining Steps If All CPUs Are Sun Models
If
all
of your CPUs are Sun models, you need to proceed with the steps in this section
in order to avoid video problems. If
any
of your CPUs are
not
Sun models, use the
alternative steps in
Section 3.5.2.C
on the next page.
3. Before you power up any CPUs, try to change the Switch’s keyboard output
on all of its CPU ports from IBM PS/2 type to Sun type. If your Switch’s
firmware is a recent enough version, a “universal Sun keyboard mode”
command will be active until you set a password for the Switch. Press and
release the [Control] key on your Sun keyboard, then type the letter [M]
followed by the numbers [5] and [0], then press and release [Enter]. This
should cause all of your CPU ports to switch to Sun keyboard-mode output.
Now
use the Switch’s front-panel LEDs and pushbuttons to select one of
your Sun CPUs (see
Section 2.3
) and power up that CPU. It should boot
properly and output video. If it doesn’t, power it back down, unplug the
keyboard strand of the CPU cable from the CPU’s keyboard port, plug a Sun
keyboard into that keyboard port, and power the CPU back up; this will
definitely give you video. Once the CPU boots with video active, remove the
