One R450 MC Not Syncing with the Host Database
First Steps
Before leaving for the site, assess the health of the R450 MC using the
host system.
• If the R450 MC is offline, this indicates that the power, power
supply, CPU, or backhaul modem may not be functioning.
• Some sites are configured so that an operator can log into the
R450 MC remotely, look at the logs, and watch the system activity.
If the R450 MC is offline but it is still possible to log into the
system, this indicates that the computer and backhaul modem are
both functional.
Initial Site Activities
• Open the R450 MC and inspect the equipment.
• Make sure that there is no obvious physical damage to the system,
such as evidence of burned components or wires, which may
indicate a lightning strike. If there is any evidence of physical
damage, the R450 MC should be replaced with the spare and
returned to Neptune's repair facility.
Troubleshooting this problem requires going to the R450 MC site.
For instructions on how to assess the health of the R450 MC, refer to “Using
System Health” in the “System Health” chapter of the
