Upgrading processor cards

You can upgrade or downgrade a processor card (CP or FP) from one version
to another. Upgrading means to replace an existing processor card with
another card of the same type but offering additional services or capacities.
Downgrading means to replace an existing processor card with another card
from a previous release with fewer services. Upgrading a card means:
• replacing a card with one of the same card type and product engineering
code (PEC) but a later vintage (version)
• replacing a card with an equivalent one that has the same card type but a
different PEC
• replacing an in-service (or failed) card with one that has a different card
type and PEC and requires the card slot to be decommissioned and
reconfigured in software
The following upgrade activities benefit the shelf performance, but they are not
considered card upgrades:
• adding an FP to an empty slot
• adding an FP to create or increase a sparing configuration
• re-configuring spared FPs to operate as unspared FPs
