The IP500 V2/V2A control unit has two SD card slots, labeled System SD and Optional SD respectively. These are used as follows:
•System SD Card
An Avaya System SD card must be present in this slot at all times. This card holds copies of the IP Office firmware and configuration.
•The card's unique ID number is used to validate any subscriptions used by the system. Note that this means all system subscriptions 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 IP Office Subscription mode, add an 11 prefix to the 10-digit number.
•If Embedded Voicemail is being used for voicemail, auto-attendants and announcements, the card stores the prompts for those services and acts as the message store for voicemail messages.
•Prior to any planned shutdown or restart of the system, the current configuration running in the system's RAM memory is copied to the /primary folder on the System SD card and to the system's non-volatile memory.
•Following a restart, the software in the /primary folder is loaded by the IP500 V2/V2A control unit. If the required software is not present or valid a sequence of fallback options is used, see Booting from the SD Cards for full details.
•Following a restart, if present, the configuration file in the /primary folder is loaded by the control unit. If no file is present, the system will check for a file in its internal non-volatile memory. If no copy is found, it generates a default configuration file. See Booting from the SD Cards for full details.
•Once each day (approximately between 00:00 and 00:30), the system copies its current configuration from its RAM memory to the /primary folder on the card.
•Configuration changes made using IP Office Manager, are first written to the copy of the configuration file on the card, and then merged with the configuration running in the system's RAM memory.
•The write lock setting on the System SD card is ignored.
•Optional SD Card
A card does not have to be present in this slot for normal operation. The slot can be used for various maintenance actions.
•A card with updated software or a configuration file can be inserted and those files then transferred to the System SD card. See Backing Up to the Optional SD Card.
•The contents of the System SD card can be copied to the Optional SD card while the IP Office system is running. See Loading Software from an Optional SD Card.
•The write lock setting on optional SD cards is honored.
SD cards should always be shutdown before being removed from a running system. Though the card slot LED indicates when data is being written to an card, lack of flashing LED is not a sufficient safeguard. Shutting down the card disables Embedded Voicemail and IP Office Web Manager.
Non-Avaya cards can be used in the Optional SD slot as long as they match or exceed the following specification:
•Only Avaya System SD can be used in the System SD slot:
oCurrent Avaya SD cards are 8GB. The use of older 4GB cards is not recommended.
•Non-Avaya cards can be used in the Optional SD slot as long as they match or exceed the following specification:
oSDHC 4GB minimum Class 2+. Single partition FAT32 format.
oThe card size should match or exceed that of the System SD card being used by the IP500 V2/V2A control unit.
