connected to the unit IO makes the controller operation unsuitable for the prevailing traffic

•
Is the local power supply currently stable and unlikely to be interrupted? An interruption to the
power during a GSPI peripheral update may result in one or more of the GSPI peripherals
requiring repair.
When a suitable time for the upgrade has been determined and reached then the upgrade can
be initiated by pressing the “Start” button on the Peripherals – F/W Update web page. Progress
information will be displayed during the upgrade with the page returning to its initial state a little while
after the upgrade completes.
On successful upgrade, the Peripherals – F/W Update web page will be refreshed.
9.3. Updating Plus Peripheral Firmware
It is possible to update the firmware running in the Nodes and CIC. Time taken to update a peripheral
varies depending on peripheral type, but it is typically a junction with two CIC and 25 nodes may take
half an hour. The operation of the Nodes and CIC are not stopped during this process so the junction is
able to operate during the download stage.
9.3.1. Delivery of Updates
The firmware for the Nodes and CIC peripherals is held within the EFC file system and so any update
of unit firmware could contain an update to the firmware for one or more types of GSPI peripheral as
well (see above). Consult the release information for the firmware update for details of the changes it
contains and the actions which should be taken.
9.3.2. Indication of Update Being Required
After upgrading the EFC, if the new firmware contains updated firmware for the Nodes or CIC then this
will be indicated by a fault in the Fault Table.
9.3.3. Performing and Update
If it is determined that an update is required, then the following should be considered before performing
the update:
•
Is the unit connecting such that loss of the CIC for a few minutes could cause a problem?
•
Is the local power supply currently stable and unlikely to be interrupted? An interruption to the
power during a CIC or Node update may result in one or more of the devices requiring repair.
When a suitable time for the upgrade has been determined and reached then the upgrade can be
initiated by pressing the appropriate “Start Download” button on the Plus+ F/W Download web page.
Progress information will be displayed during the upgrade with the page returning to its initial state a
little while after the upgrade completes.
