Notes: If the software or firmware version on the newly inserted card is different
from the software or firmware version on the replaced card, the Upgrade
Wizard must be run again to resolve the version conflicts.
The conflict is reported on the Dashboard in the Model accordion of the
Device Information widget and on the Versions tab of the Support page.
The process to replace an option card is as follows:
1. Disconnect any cables from the option card to be replaced.
2. Loosen the two captive screws that retain the option card in the base chassis.
3. Holding the captive screws, pull the option card from the unit, (observe the
handling precautions and advice for module pairs where applicable).
4. Carefully remove the replacement option card from its anti-static package, and
insert it in to the base chassis, slotting the card edges in to the card guides.
5. Push the card home; so that the rear panel is flush with the rear of the base
chassis (observe the handling precautions and advice for module pairs where
applicable).
6. Tighten the two captive retaining screws.
7. Connect any external cables to the replacement option card.
Note: If the replacement card is of the same type as the failed card, has the same
capabilities (licenses), is at the same software version and is fitted in the
same slot, then it will be automatically configured to the same settings as
the failed card. If the replacement card is of a different type then an alarm
will be generated.
7.10.6 Option Card Plug and Play
The unit is designed around a Plug and Play concept to make it as easy as possible
to add new option cards and functionality. This means that the chassis and Host
controller card provide a base level of functionality, while any specific functionality
associated with an option card is contained on the option card itself.
A good example of this is MPEG SI generation. The Host controller provides the
functionality to generate and play out the SI required by a Transport Stream.
However a VCM is required to provide any descriptors required for any elementary
stream types that it generates.
