Field Replaceable Units
SSD
In case of a Solid-State Drive (SSD) failure of an EX controller, you must replace the EX Controller unit:
1. Make a note of the slot number and telephony card (PRI, DSP, FXO, or FXS) installed into the slot.
For example, slot 1 has PRI card installed, slot 2 has DSP card installed, and so on.
2. Ensure that you have the latest backup file from Server Manager.
3. Remove the telephony cards from the EX Controller. See Telephony Cards.
4. Procure a new EX Controller. For part numbers, see Models and Part Numbers.
5. Install the EX Controller. See Hardware Installation.
NOTE: Ensure that you install the cards in the slots as noted in step 1.
6. Deploy the system software. See Software Installation.
Ensure to select the Restore via console option in the EX Controller Deployment Tool.
7. Restore the database from the Server Manager (Administration > Restore).
Telephony Cards
If you are replacing a card, it is recommended to replace a card with the same type of card in a slot. For
example, replace an FXO card with a new FXO card. If you replace a card with a different type of card or
move a card to a different slot, then the configuration data is lost. You must deprogram the old card and
reprogram the new card.
If you are installing a new card, refer to the guidelines in the following table for installing a new slot to the
current slot configuration:
