The IP Office system requires an Avaya System SD card in order to operate. The card is inserted into the System SD slot on the rear of the control unit before the system is started.
•This card carries the firmware and various other files that the system loads when it powers up.
•The card's serial number is used to validate any licenses used by the system. Note that this means all system licenses are tied to the particular SD card and not to the control unit.
•The card's ID number is printed on the card's label after PLDS ID, FK SN or FK depending on the age of the card. On newer cards is a 12-digit number. Older cards may have a 10-digit number. For PLDS licensing, use the 12-digit number. On older cards, for licensing, prefix the 10-digit number with 11.
•Once the system is operational, the card holds copies of various files such as the system configuration.
•If Embedded Voicemail is used to provide voicemail services rather than a separate Voicemail Pro server, then the System SD card stores all the voicemail prompts, messages, etc.
For a new IP Office control unit, the version of IP Office software that it loads from the system SD card when it is first powered up becomes its original software level. That value is written into the control unit's permanent memory and cannot be changed.
Therefore, it is important to ensure that the System SD card has been loaded with the correct version of software before the system is first powered up. This is done by using IP Office Manager to load the required level of software onto the SD card.
