After you press Y, the top amber LED will begin to flash slowly
(about 1 blink per second) and will continue to flash for the
duration of the make-microcode-tape process. If there is a tape
in the CTS, the tape is ejected to prevent the CTS from writing
over tape that may have some data on it.
6.
Insert a blank data cartridge in the CTS.
When the data cartridge is inserted, the CTS loads it and copies
its control code, servo code, and EEPROM code (if specified) to
the tape. The bottom green LED will begin to flash. (The rate of
flashing varies between slow and fast as the CTS switches
between normal-speed and high-speed tape operations.)
If the tape is made successfully, the CTS unloads and ejects the
data cartridge, and the following message appears in the CTS
Monitor program:
G: Load tape made successfully and tape ejected!
7.
Remove the data cartridge from the CTS, label it as a microcode
update tape, list the microcode level, and store it in a safe
location to prevent it from being used inadvertently.
Note:
If an error occurs while the CTS is making the microcode
update tape, the top amber LED will flash at a faster rate
(about 4 blinks per second) and the tape is not ejected.
One of the following messages is displayed in the CTS
Monitor program:
E: Can’t write on tape –- tape is write
protected!
B: Can’t start operation until self test
and autoload are done!
o: Hardware must be upgraded to support
this operation!
Press the unload button to eject the tape and restore normal
CTS operation. Then, reset the CTS, wait until it is idle, and
restart the process with a new 15m tape.
