CHAPTER 7: Using the Serial Ports

7.2.4OPTIONS 4 AND 5. SEND MAIN PROGRAM/SEND KERNEL (DISTRIBUTE UPGRADED

FIRMWARE)

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.
