3.4 Troubleshooting
In case of abnormal operation, technician should diagnose abnormality via remote access or
directly connecting to repeater using Ethernet cable. If technician is required to conduct repairs
due to major alarm, repeater should first be powered off, and then technician should prepare
the proper measurement equipment before trying to fix the problem.
3.4.1 Simple Troubleshooting Method
1) Verify LED Status, both on external LED’s as well as internal module LED’s
- Normal operation: Green light on. Alarming: Red LED on.
2) Technician should check external and internal connectors to ensure all connections are tightly
secure. These connectors should be cleaned regularly.
3) If technician thinks there is a serious problem, call technical support.

* The Downlink Output Power should not exceed the m
aximum composite power spec for this unit.
* If the Downlink Output Power is not exceeding the co
mposite power spec for this unit, try to increase the Do
wnlink Upper Limit on the RF Configuration Page.
* Add equal amounts of Uplink and Downlink attenuati
on until the Downlink Output Power is less than the Do
wnlink Upper Limit.
* Set the ALC Downlink Limit on the RF Configuration P
