Measure the voltage between NEG (-) and RTN (+) on the DC power distribution box.
Voltage Range
CAUTION
Do not power on the equipment if the power supply voltage does not meet the requirement.
Checking Fiber Attenuation
CAUTION
Wear protective glasses or goggles when you look directly at optical ports to check fiber attenuation.

meter
1 Measure the output power of the
optical source.
NOTE
If the difference between P2 and P1 is less than 1 dB, the fiber connection is normal. If the difference is larger than
1 dB, clean the fiber. If the difference is still larger than 1 dB after cleaning, replace the fiber.
NOTE
Setting the wavelength of the light source to approximately 1550 nm and the wavelength range of the optical power
meter to 1550 nm is recommended. After the equipment is powered on, you can also use a board that can
generate optical signals as a light source.
