6. Troubleshooting
The following section provides some basic troubleshooting information to assist users in case
they suspect there is an issue with the system.
6.1 Front Panel Indications
You can use the front panel indicators to assess the status and operation of the unit. Under
normal operating conditions the user should see:
Green Status Indicator on both power supplies
The front panel clock should display the last two digits of the year, the correct Julian
Date (see appendix D.) and the correct time (UTC). The time should also increment
each second.
The Alarm Light is Off
The OSC Lock, Input A or Input B (for redundant systems), and Outputs Enabled
lights are green. Redundant fiber input flashing green (auto) or red (manual).
6.2 Alarm Light
The alarm light will turn red when the unit has detected a hardware failure or an event has
occurred that may cause the timing signals output by the unit to be outside of their specifications.
Either power supply missing/failed or without AC/DC input power.
Any output module reporting a failure or is not locked to the reference
There is an internal hardware error
Reference clock wander has exceeded 100 ns from the input fiber frequency
Master reference signal is missing.
Over temperature (65 C)
I2C Bus error
System settings do not match the specified configuration in the system mode
If the alarm light is on users can determine the exact cause of the alarm by accessing the
command port and typing the status alarm command and obtain a list of the current alarms.
If the alarm light was on and is currently off, users can connect to the command port and type the
command syslog to obtain the list of errors from the error log file maintained by the system.
6.2.1 Power Supplies
The system has two power supplies and is capable of operating from either supply in the event
one of them fails. If one of the status indicators on the power supply front panel is red there is a
problem with that supply. The front panel alarm light should also be on. Power supply #1 is on
the left and Power Supply #2 is on the right. The possible problems are listed below:
Power Supply has failed
Internal Fuse is open
Power Supply is unplugged, make sure the power supply is plugged in
