Cisco Cisco OptoStar II Driver Amplifier 安装指南
Starting up the Module
Initialization
When the OptoStar II RF switch module is powered on, the module will perform
a self-test.
Follow these steps to perform the self-test:
1. Turn the front panel switch of the OptoStar II power supply module to ON
a self-test.
Follow these steps to perform the self-test:
1. Turn the front panel switch of the OptoStar II power supply module to ON
position.
2. When the RF switch module starts up, it will perform a booting initialization
for about 5 seconds.
3. During the initialization, the power LED and the alarm LED on the front
panel will be illuminated, and the communication status is shut off.
4. Once the initialization is completed, the status indicator will return to normal.
Communication is enabled and the module is operational.
CAUTION:
•
The module must be initialized; any equipment that cannot be initialized must

be returned to the manufacturer for repair.
•
When everything becomes stable, the module still needs to warm up for at least
one hour, to make sure that its performance is normal.

Signal Inspection
A DB meter or spectrum analyzer can be used to measure the RF output level via
the RF test point on the front panel. The RF input level can be adjusted if
necessary. The actual value of the input level (dB) equals to the measured value
+20. 0 ± 1. 0.
