CPU Card
8. Once the inactive bin has completed loading, the system will automatically check that it
has loaded properly. If a checksum mismatch message appears, then the bank must be
loaded again. Once the bank is loaded and passes checksum validation, it will be marked
as "full".
9. Press carriage return on top of the full status. Three options appear. If this is a simplex
(single-processor) system, then select actv. NOTE: Choosing to actv a load on the same
card that is currently carrying the system traffic will cause a restart of the system. For a
duplex (dual-processor) system, the actsw will appear and should be used.The actsw
command results in minimum traffic impact on the supported card list.For either the actv
or actsw command, confirm the request to switch.
10. For a simplex system, load the inactive processor and the upgrade is complete. For a
duplex system, repeat steps 5, 6 and 7 to load the new software into the 'full' bank.
11. Once the bank has loaded and the checksum has passed, once again press carriage return
and choose the actsw command. Confirm the switch.
12. On the newly active card, load the inactive processor bank. This will complete the upgrade
on this card.
13. Arrow to the "full" bank from step 12 above, and once again choose actsw to make this
bank active and switch to the other card.
14. On the newly active card, load the inactive processor bank. This completes the software
upgrade on this node.
15. Be sure to save a database backup in order to preserve the system settings.
