Updating Remote Node Peripheral Firmware (Rag, Wait Indicator, Pdu, Nearside Indicator, Smartloop) And Cic Firmware - Siemens ST950 Plus+ User Manual

Appendix
B.3 Updating Remote Node Peripheral Firmware (RAG, Wait
Indicator, PDU, Nearside Indicator, Smartloop) and CIC
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 less than one minute per
peripheral. The operation of the Nodes and CIC are not stopped during this process so the
junction is able to operate during the download stage.
B.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.
Indication of Upgrade being Required
B.3.2
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.
B.3.3 Performing an 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.
