1A. 2-port model (SW721A-R4): Making sure that the connected CPUs and any
connected submasters are OFF (powered down), take the output cord of the
ServSwitch’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’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, 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 ServSwitch 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. Power up any directly connected CPUs and any connected submasters one by
one, giving each one time to boot completely before turning ON the next
one. When the CPUs are powered up after the ServSwitch, the Switch
emulates all keyboard and mouse functions for automatic bootup. (You might
want to issue a Keep Settings command after initial bootup, so that the Switch
saves the mode settings it has autodetected to nonvolatile memory.)
4. Power up any CPUs connected to submasters one by one, giving each CPU
time to boot completely before turning ON the next one.
