Issue
Performing a firmware upgrade on a reader expander module via the SP-C's web page will fail with the message:
"Error - The module failed to restart in boot mode"
Product Line
EcoStruxure Security Expert
Environment
SP-C, SP-RDM2, SP-MRDM2.
Cause
Cause 1
- There was an intermittent communications fault hindering the update process.
Cause 2
- There are Smart Card Readers connected to the reader expander module, which are set to RS485 communication.
- This appears to be causing RS485 communication issues between the SP-C and the reader expander which is hindering the firmware upgrade process.
Resolution
For Cause 1
- Run the module upgrade process again.
For Cause 2
- Physically remove all connected RS485 Smart Card Readers from the reader expander module being upgraded.
- Run the module upgrade process again.
- Once the reader expander firmware has been successfully upgraded, reconnect all Readers.
