Procedure 58
Performing a feature and ISM parameter upgrade using a keycode diskette.
1) Log in on a system terminal and load LD 143.
>LD 143
CCBR000
.
2) Insert the new keycode diskette into the floppy drive on the active IODU/C card.
3) Print the pending keycode contents.
4) Enter the KDIF command and select keycode comparison options.
Note: Ensure that the new keycode does not lower ISM limits or reduce features compared with the existing keycode. If it has been determined that the keycode lowers ISM limits or reduces features, do not continue
with the KNEW command. Contact the Nortel Networks order
management representative.
. KDIF
Please use: KDIF <param1> <param2> with the following parameters:KSHO F1 (or F0) print the contents of the candidate keycode in the floppy drive on the active Core. Where:
F1 = Core 1
F0 = Core 0----F0 always for PII systems!!
NEW Accepted new keycode
REC Currently used keycode
OLD Previously used keycode
F0 Candidate keycode on diskette in /f0 floppy drive
F1 Candidate keycode on diskette in /f1 floppy drive
HD Candidate keycode which was uploaded to hard disk
Enter the keycode comparison option. The new keycode option is shown in bold.
Note: In the following example, the (REC) currently used keycode will be compared with the new keycode disk in floppy drive F0. The limits shown are for example purposes only.

5) Select the new keycode for activation using the KNEW command.
. KNEW F0
The uploaded keycode is validated against the security device.
If the following system message is displayed:
CCBR020 New Keycode accepted and activated successfully.
Sysload is not needed!
This means that the new keycode is eligible for instant activation and no further user action is required. Go to steps 6 and 7.
If the keycode is not eligible for instant activation, a Sysload is needed to activate the new keycode and the following system message is displayed:
CCBR009 New Keycode accepted. New ISM limits and feature
packages will be activated during the next Sysload (Cold Restart).
Go to step 8.
6) Load LD 22 and confirm that the new ISM parameters have been
updated.
>LD 22

....
If ISM limits are correct, then the keycode installation is complete.
See “Reverting to the previous keycode with the KRVR command” on page 220 if ISM limits are not increased or problems exist.
7) Once it is confirmed that the keycode changes taken effect as expected,perform a data dump in LD 43.
8) Perform the following steps for keycodes that are not eligible for Instant *** see manual for parallel re-load instructions***
