CHAPTER 5: Operation
At this point, make
very sure
that the Wizard MP is receiving adequate power. The
upgrade program monitors the Wizard MP’s voltage and won’t allow an upgrade to
proceed if the voltage is insufficient. If you’re using the Wizard MP’s optional
power supply, it’s definitely going to get the power it needs. If it’s being powered
by the attached computers, it’s normally possible to perform an upgrade when the
Wizard MP is powered by a single computer, but it’s a good idea to power up all of
the computers attached to the switch anyway. This minimizes the possibility that
power will fail during an upgrade due to a sudden brownout, cable disconnection,
etc.
3. While holding down the Wizard MP’s front-panel pushbutton, use the
recessed switch on the bottom of the chassis to do a warm reset of the Wizard
MP as described in
Section 5.11
. Keep holding down the pushbutton while
the Wizard MP finishes its bootup process, until its 7-segment display shows a
lowercase “u” to indicate that the Wizard MP is ready to be upgraded:
4. Run the SSWMP.EXE firmware-upgrade program that you downloaded in
step 1, using the DAT file you downloaded as the argument. The command
line should be “SSWMP MP
xyz
SP.DAT”. Or just type in “MP
xyz
SP” and hit
return to run the batch file you also downloaded in that step; it contains the
proper command line. Follow the directions that appear on the host PC’s
screen to transfer the new firmware to the Wizard MP. The Wizard MP’s
7-segment display will change to show an uppercase “U” and its dot will flash
to show that the Wizard MP’s receiving data from the PC (the upgrade
program rewrites the Wizard MP’s existing firmware code with the code in the
MPxyz.HEX file):
