Troubleshooting Software Update - Safran VersaSync User Manual

2. The network clients have to be configured to synchronize to VersaSync's
address. For additional information on syncing Windows PC's, see

computers/. The last section of this document also contains troubleshoot-
ing assistance for Windows synchronization. For UNIX/Linux computer syn-
chronization, please visit http://www.ntp.org/.
3. If at least one PC can sync to VersaSync, the issue is likely not with Ver-
saSync itself. The only VersaSync configurations that can prevent certain
PCs from syncing to the time server are the NTP Access table and MD5
authentication. See
work or PC issue likely exists. A firewall may be blocking Port 123 (NTP
traffic), for example.
4. NTP in VersaSync must be "in sync" and at a higher Stratum level than
Stratum 15 (such as Stratum 1 or 2, for example). This requires VersaSync to
be either synced to its input references or in Holdover mode. Verify the cur-
rent NTP stratum level and the sync status.

Troubleshooting Software Update

When experiencing slow data transmission rates, or other network issues, it may
be possible that a system software update will be aborted due to a web server
timeout during the transfer.
In such an event, the Upload New File window will disappear, and the Upgrade
System Software window will be displayed again instead.
Should this happen repeatedly, you can transfer the update file using a file
transfer protocol such as scp, sftp or ftp, if security is not a concern. The
update can then be initiated from the Web UI or Command Line.
