Appendix C - Light Patterns and Test Switch Settings
MicroRouter 900i Light Patterns
The MicroRouter 900i uses a number of light patterns on its front LED bar to indicate operating conditions.
2 & 9 on steady: Router is powered on.
ϖNote: Lights 1 and 10 are directly connected to the router’s 10BaseT interface and indicate 10BaseT link (1) and 10BaseT polarity (10).
Traffic Indicators
Scan from 2 to 5: Ethernet receive packet
Scan from 5 to 2: Ethernet transmit packet
Scan from 6 to 9: WAN receive packet
Scan from 9 to 6: WAN transmit packet
Other Indicators
5 & 6 on steady: Flash ROM checksum in progress
5 & 6 flashing: Router stacks starting up
2,3,4 & 7,8,9 flashing: Running from ROM
2,3,4 & 7,8,9 on solid: Erasing Flash ROM
2,3 & 8,9 on solid: Writing Flash ROM
4 & 7 on solid: Compressing Flash ROM image
Level 1 Panic Indicators
Any continuous flashing pattern not noted above may be caused by a software “panic.” This is a sign that a condition has been detected that the software does not know how to deal with: either an unusual network condition, or a hardware failure.
ϖNote: Level 1 panics are very unusual. These are not the same as Level 2 panics, which cause the router to save the reason for the panic and restart. The existence of a Level 2 panic signature will be reported by CompatiView or the command line.
