Memory Error Messages
The messages in this section indicate problems with the memory subsystems
on the Model 281xSA hub: DRAM, EPROM, flash EEPROM, and NVRAM.
Bad BOOT EPROM checksum!
Actual Checksum: [hexnum], needed checksum [hexnum].
The BOOT EPROM checksum is checked at program startup/power-up time.
This failure means that the BOOT EPROM is defective.
Bad checksum.
Bad block index.
Empty block.
The configuration data in the NVRAM has been corrupted, which can happen if
power fails at the instant the configuration is being saved. The Model 281xSA
hub will try to rewrite the NVRAM to factory default settings. If it succeeds,
continue to use the NMM. If the error repeats, contact the Customer Service
department of the organization from which you purchased your System 2000
equipment.
Invalid flash checksum!
The flash memory checksum (32 bits) is checked at program startup/power-up
time. This failure means that the local image in flash memory is invalid. The
Model 281xSA hub firmware automatically sets the image load mode to
REMOTE if this failure occurs.
Reset Message
This message appears when you reset the Model 281xSA hub.
Waiting for Wdog to reset the NMM…
This informational message indicates that the Model 281xSA hub is not
running and is waiting for the hardware to detect the failure and reset the Model
281xSA hub.
NOTE:
If this error happens, you will need to reprogram the configuration
data. Use the k command [Reset NVRAM to factory defaults] in the Boot Main
Menu.
