Troubleshooting For The Repeater - ShoreTel 930D User Manual

Solution: The base is having difficulty synchronizing with other bases. In some cases this can take up
to 10 minutes. If the issue extends longer, it may indicate that the base cannot find a free DECT
channel to use to communicate with other bases. Check for interfering DECT or other RF devices near
the base.
Another cause may be an error in the configuration files for this base. Re-check the configuration files
for the base, following the guidelines provided in the ShoreTel IP Phone 930D Planning and
Installation Guide.
Problem: The LED indicator on the base is winking red (800 mS on/200 mS off).
Solution: The base does not detect an Ethernet connection. Check the connection between the base
and the Ethernet switch.
Problem: The LED indicator on the base is solid red
Solution: This indicates a critical error. Try power cycling the base: Unplug the Ethernet connection to
the base to remove power for a few seconds, then reconnect. If the issue is not resolved, the base has
encountered a non-recoverable error and needs to be replaced.

Troubleshooting for the Repeater

Problem: The LED indicator on the repeater is slow flashing green (400 mS on/250 mS off) and never
becomes steady green after installation.
Solution: The repeater is having trouble connecting to either the base to which it is registered or to the
repeater from which it receives synchronization.
First try power cycling the repeater to resolve the issue.
If the issue is not resolved, follow the procedure below
access site survey mode on the handset. Then check that the signal level from the hosting base or
repeater is between -65 and -75 dBm when measured near the repeater with the flashing green LED.
(A value of -70 dBm or better is recommended.) If the signal level is outside of this range, the repeater
needs to be relocated to synchronize properly.
Problem: The LED indicator on the repeater is alternating red and green flashing.
Solution: The repeater is in the recovery mode and cannot find a base or cannot allocate an RPN.
Load the project file for the installation into the ShoreTel IP930D Configuration Tool and check the
following:
Check for typographical errors in the IPEI values for each repeater.

Check that the synchronization source for every repeater is correct.

Check that every repeater is associated with the correct base.

You can check each of these items by selecting a repeater and viewing properties in the right-hand
pane of the Configuration Tool. Alternatively, you can print the installation summary to check these
items. See the ShoreTel IP Phone 930D Planning and Installation Guide for assistance.
