5. STATE MACHINE
Identification
• Shared memory.Operation mode = 0x0000 14FC
• The firmware responds on the network to ICMP, SNMP, and TFTP requests.
• The firmware communicates with best-effort traffic only.
• Shared memory.Lifesign value increments every 5 ms
Operation
• SNMP
• ICMP ping
• TFTP
• Continuous internal end system diagnostics
• Continuous switch diagnostics
• Continuous Built-In Tests (CBITs) are performed
User Operations
• Telemetry (SNMP)
• Network management (ICMP ping)
• Commands (SNMP set requests)
• File upload (TFTP)
• File download (TFTP)
Transitions
• At the user’s request the firmware transitions to RECONFIGURE mode.
• In the case of an error, the firmware transitions to ERROR mode.
Remarks
None.
5.2.4 RECONFIGURE Mode
In this mode, the firmware configures the internal end system and the switch engine with the configuration
selected through the GPIO interface (see Section 3.2.2.1 on page 17) or a long-press of the reset button
(see Section 3.2.3.2 on page 19). Once the reconfiguration is complete, the firmware will switch back to
CONTROLLER mode.
Identification
• Shared memory.Operation mode = 0x0000 1502
• There is no firmware communication on the network.
• Shared memory.Lifesign value increments every 5 ms
