ServSwitch User's Manual

MATRIX SERVSWITCH™

What you do now depends on whether the download succeeds or fails:

If something goes wrong during file transmission, you might receive an error message

advising you that a “checksum error,” “record error,” or “data error” has been

detected. This message will be followed by:

Receive failed

Try again Y/N

Error messages may be caused by any of these problems:

• Corrupted firmware-upgrade file

• Loose, broken, or defective RS-232 cable

• RS-232 protocol not configured correctly

• Bad transmit or receive levels

• Hardware problem on transmit or receive side

Press “Y” and then [Enter] to try again, and you will be returned to the initial

message, at which point you can resend the file:

Waiting for file...

Or press “N” and then [Enter] and the prompt "Hit enter to boot" will appear.

Press the [Enter] key to launch the Switch’s diagnostics with the port board’s

firmware unchanged.

If reprogramming seems to succeed, the procedure is finished if you’re using a single

2 x 4 Matrix ServSwitch, which only has one port board. But if you’re using a

daisychained system with more than one Switch, or even if you’re using a single

2 x 8 or 2 x 16 Switch (which have more than one port board), you must use

option 4 or 5 of this menu to copy the new firmware to the other port boards in

your Matrix ServSwitch system, as described in Section 7.2.4. (If you leave different

versions of these programs running on different port boards in your Switch system,

the system will probably malfunction, and to fix it you’ll have to redownload and

distribute the firmware anyway.)

Once you’ve copied the new firmware throughout the system, restart the

Switch(es) (see Section 7.2.7) and watch the power-up diagnostic screen (see

Section 3.5.1) to make sure that the “Kernel revision” and/or “Program revision”

now match the revision number of the file(s) you just downloaded. Then test how

the system performs. If it seems to behave properly, you’re in business. (And you

can continue configuring the port board if you need to.)
