6. SD Card Management
The IP500 V2 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 and is used as the IP500 V2 control units non-volatile memory.
· Each Avaya System SD card has a unique Feature Key serial number which is used for generating and
validating licenses entered into the IP Office configuration.
· The card stores the prompts for embedded voicemail operation and acts as the message store for embedded
voicemail messages.
· Prior to any planned shutdown or restart of the IP Office system, the current configuration running in the IP
Office system's RAM memory is copied to the /primary folder on the System SD card.
· Following a restart, the software in the primary folder is loaded by the IP500 V2 control unit and, if necessary,
by the external expansion modules and phones.
· Following a restart, if present, the configuration file in the primary folder is loaded by the OP500 V2 control
unit. If no file is present the system will generate a default configuration file.
· Once each day (approximately between 00:00 and 00:30) the IP Office will copy the current configuration
running in 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 IP Office system's RAM memory.
· The write lock setting on cards in the System SD card slot is ignored.
· Optional SD Card
A card does not have to be present in this slot for normal IP Office operation. The slot can be used for various
maintenance actions.
· A card with an updated IP Office software or configuration can be inserted and those files then transferred to
the System SD card in order to upgrade the IP Office system.
· The full contents of the System SD card can be copied to the Optional SD card while the IP Office system is
running.
· The write lock setting on cards in the Optional SD card slot is honored.
SD Card Removal
SD cards should never be removed while being used. Though the SD card slot LEDs indicate when data is being
written to an SD card, lack of flashing LED is not a sufficient safeguard. The IP Office Manager provides methods to
shutdown and restart an individual card
System SD card is removed, licensed features will continue operating for up to 2 hours.
