Caution!
To avoid damaging the module, always handle carefully (see section 7.11.1 ) and
avoid electrostatic discharge (see section 7.11.2 ).
Dual Slot Modules
If the failed card is one of a module pair (i.e., CE-x or CE-xA), both cards must be
unplugged and replaced in the following sequence:
1. Remove the Pre-processor (bottom) card first then the Encoder (top) card.
2. Wait for at least 40 seconds.
3. Replace the Pre-processor (bottom) card.
4. Replace the Encoder (top) card.
If the software or firmware version on the newly inserted card is different from the
software or firmware version on the replaced card, then the Upgrade Wizard has to
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.
To replace an option card:
1. Disconnect all 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 all external cables to the replacement option card.
Note: If the replacement card is of the same type as the failed card, i.e. if it 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.
