Booting From The Sd Cards - Avaya IP500 V2 Installation Manual

7.1 Booting from the SD Cards

Once a valid ip500v2.bin file is found, the IP Office control unit will load that firmware. The source from which the control
unit binary file was loaded is then used to load further files.
Configuration File Loading
Having installed the necessary system firmware files as above, the IP500 V2 control unit requires a configuration file:
· If the IP500 V2 booted using binary files from an SD card location, it looks for a valid configuration file in the same
location.
· If a configuration file is present and valid, it is loaded.
· If a configuration file is present but is not valid, load the configuration copy in its non-volatile memory if
present, else it assumes a default configuration.
· If a configuration file is not present, use the non-volatile memory copy as above unless the reboot is as a result
of a default system command.
· If the IP500 V2 booted using binary files from its non-volatile memory, it will also load the configuration copy from
that location.
· It will indicate a boot alarm (see below).
· It will attempt to restore the firmware file in the System SD card's /primary folder using the copy in its non-
volatile memory.
· The normal boot up process of upgrading expansion module firmware does not occur. If the File | Advanced |
Upgrade command is used, only external expansion modules actually present in the system are listed for
upgrade.
Post Boot Operation
During normal operation, configuration and binary files sent to the System SD card /primary folder using IP Office
Manager are also written to the non-volatile memory.
If the system has booted from its non-volatile memory due to an SD card problem, it is still possible to upgrade the
ip500v2.bin file using the IP Office upgrade wizard.
Installing IP500/IP500 V2
IP Office 9.0
When being powered up, the IP500 V2 control unit looks for a valid ip500v2.bin
binary file to load. It does this using the possible source below in the order shown,
skipping to the next source if the file is not present or is not valid.
1. System SD card /primary folder.
2. The control unit's own internal non-volatile memory. Once a system has
been installed, it uses its non-volatile memory to keep copies of the
configuration and system binary files it is using. These can be used to
restore operation during a system reboot. Note that though a system can
boot from non-volatile memory, a System SD card must still be present for
correct system operation.
3. System SD card /backup folder.
4. Optional SD card /primary folder.
5. Optional SD card /backup folder.
6. If no file is found, the control unit will fallback to making BOOTP requests to
the network. IP Office Manager can respond the BOOTP request. See
Erasing the Operational Firmware .
