You only need to use the procedure in Section 7.2.3 to upgrade the main program
or kernel of one port board in one Matrix ServSwitch. Afterward, unless the Switch
is a standalone 2 x 4 model (which only has one board), you’ll need to use the
procedure described in this section to send the upgrade simultaneously to all other
port boards in your Switch system.
At the serial options menu, to send the main program systemwide, press 4; to
send the kernel program, press 5. These messages will appear for either option:
Boards to update - n
You are about to copy the firmware from this board to all
other boards in the system.
Are you sure? Y/N
Before responding “Y,” make sure that all other Switches in your system are
attached and powered on. Also make sure that the number of port boards—the
number that will appear where the variable “n” is shown in the message above—
agrees with the actual number of port boards in the system minus one. (The
number of port boards should equal the total number of Matrix ServSwitch CPU
ports divided by four.) If the number does not agree, reply with “N”; turn on any
inactive Switches, make sure all Expansion Modules and cables are firmly seated,
and press 4 or 5 again. If there is still a mismatch, call Black Box for technical
support. But if the number of port boards is now correct, reply with “Y.” This
message will appear:
Sending flash program code to system......................
When the transmission is complete, the system returns you to the serial options
menu; wait at least 10 seconds, then cycle power to all of your Switches. Check
their power-up diagnostic screens (see Section 3.5.1); if the new “Kernel revision”
and/or “Program revision” number(s) match those of the file(s) you just
distributed, all Switches in the system should now be operational.
