While NTP is enabled, if all provisioned servers become not reachable or fail to meet
minimum server standards, a NTPOOSYNC condition shall be raised. This alarm shall
clear when the NTP protocol is disabled or NTP server time synchronization is
reestablished.
Once the NE is power cycled, it takes approximately 20-30 minutes to initialize.
Thereafter, time synchronization will be completed, with a maximum delay time of 2-3
minutes.
Note: When configuring NTP servers on an NE network, the provisioned NTP server
IP addresses should be that of external NTP servers, not the IP addresses of GNEs.
Provision appropriate DCNs such that the external NTP servers are reachable from all
NEs within the network. This is especially important in the event of an EC cold reboot
or EC replacement. Do not use an NE as an NTP server by remote NEs.

Applicability SYSTEM
Corrective Action
At the end of each step wait to see if the fault clears. If not, continue with the next step.
...................................................................................................................................................................................................
1
Verify provisioned servers are valid and reachable. If not, consult network engineering for
correct server addresses.
...................................................................................................................................................................................................
2
Perform a warm reset on the Equipment Controller that is raising the NTPOOSYNC
condition.
CLI config card card type shelf slot reset warm
WEBUI Select the card, click the Reboot tab, select Warm Reboot >Submit.
...................................................................................................................................................................................................
3
Perform a cold reset on the Equipment Controller that is raising the NTPOOSYNC
condition.
CLI config card card type shelf slot reset cold
WEBUI Select the card, click the Reboot tab, select Cold Reboot >Submit.
