Symmetricom ND-CLK User Manual page 41

Possible Reasons/solutions:
1. The ND-CLK is in a rapid adjust mode. During this time period the red status LED
will blink/flash once per second. This is normal operation for the clock.
2. Upon acquisition of NTP during initial startup, or a change to the internal time
reference (as compared to the NTP server) caused by power loss, configuration
changes to time zone offset, daylight saving time, or entry into/from daylight savings
time will cause the clock to enter a correction cycle. This correction cycle may take
up to 20 minutes to complete (depending upon the current position of the hands
relative to the local time of clock). During this time period the red status LED will
blink/flash once per second. This is normal operation for the clock.
Problem: Clock display appears to freeze momentarily.
Problem: Clock appears to 'reset' periodically.
Possible Reasons/solutions:
1. If DHCP is enabled [Note: DHCP is enabled by default] and a DHCP server is
not active on the local network the clock will hesitate periodically while
attempting to resolve DHCP configuration. To correct the problem, switch to
manual networking configuration or determine why the local DHCP server is not
operating.
2. If the clock cannot resolve its DHCP address in DHCP mode, the unit will
periodically perform a soft restart to re-initialize its communication port and
DHCP configuration. See the trouble shooting section on fallback IP address
3. If the clock has not been configured with at least one valid DNS server (or that
DNS server is down) hesitations similar to those described in #1 will occur. At
least one valid DNS server is required for operation.
4. If the clock does not have at least one valid NTP server address configured
(primary NTP server) or the server is unreachable for extended periods the clock
will periodically perform a soft reset to re-initialize its communication port and
configuration.
Problem:
You have lost your password.
Possible reasons/solutions:
1. The password cannot be recovered if it is lost. Reset the clock to the factory
default configuration using the procedure described in the Configuration section.
After the clock has been reset to factory defaults, the unit must be reconfigured.
The default password is "public"
Problem:
Multiple error windows titled "Bad Password" continue to pop-up each time a
configuration setting is applied.
