MATRIX SERVSWITCH™
Here is what the parts of these messages mean:
Kernel is bad, load new kernel through serial port
The Matrix ServSwitch sends this message at bootup instead of the power-up
diagnostic screen when it detects that its own kernel is corrupt. The Switch will wait
to receive a replacement kernel file through the serial port on its bottom port
board—the one with CPU ports 1 through 4 on it—using the serial parameters
9600, N, 8, 1. Connect the serial cable supplied with the Switch as described in
Section 7.1 and start your terminal emulator. Transfer the file using an ASCII file-
transfer protocol. This procedure, and the accompanying messages that will
appear on your terminal-emulator screen, are described in Section 7.2.3. If the file
loads successfully, cycle power to the Switch; if the problem recurs, call Black Box
Tech Support.
BAD Address = nnnn
The kernel loader writes this message when kernel memory is corrupted,
indicating a hardware failure. The corrupted memory address is represented by the
variable “nnnn.”
Unit must be serviced
The error is unrecoverable. Call Black Box Tech Support and arrange to have the
Switch repaired; see Sections 8.2 and 8.3.
Resetting to factory defaults
The kernel writes this message at power-up when a memory error is detected
during a read from configuration memory. This also indicates a hardware failure,
but the system may continue to initialize successfully. The configuration from
another Switch should be saved to this Switch as soon as possible.
Unit halted
Refer to operation manual or call technical support
The error is major and has forced the kernel to stop processing. The Switch will
have to be serviced. Call Black Box Tech Support as directed in Sections 8.2 and
8.3.
