Reintroducing a Deskset Into the System
If there are fewer than 51 Desksets in the system and a Deskset screen displays Synch Failed or Synchronizing... for a long
time, you may need to remove the Deskset from the system and reintroduce it. This problem may have been caused by a network
disruption, the Deskset having been part of a different network, or by an AC power failure.
 To reintroduce a Deskset into the system:
1. Ensure that the Deskset is connected to the same LAN subnet as other system Gateways and Desksets. Ensure that the
PC you will use to access the WebUI is either on the same subnet as Synapse, or that the PC subnet can communicate
with the Synapse subnet. Devices on the same subnet generally share the first three octets of their IP addresses. If the
subnets are different, contact your installer.
2. If you want to retain the programming for a problem Deskset, back up the Deskset.
See “Back Up and Restore Settings” in the Synapse Administrator’s Guide at

a. Log in as administrator. Click Device Management, then Back up/Restore, and then Extension Settings in the
navigation menu at left.
b. Select the extension from the New Extension Number drop-down list, and click to save the file
to a specified location on your computer. You will need to locate and retrieve this file later, so make sure you
remember where you saved it. The default file name will be in the format:
backup_ds_[extension number]_[year]–[month]–[day]_[time].cfg.
If you back up the same extension less than one minute after creating the back up, you may overwrite the earlier
backup file.
If the desired extension number is not in the drop-down list, choose Select Extension from the drop-down menu. The
WebUI defaults to backing up the extension whose IP address was used for logging into the WebUI.
