Use the compressed air to blow off dust on the fiber end face.
NO TE
● When using the compressed air, keep the nozzle as close as possible to the fiber
end face without touching it.
● Before using the compressed air, first spray it into the air to expel deposits in the
compressed air.
Step 7 Use a fiber microscope to inspect the fiber to check whether there is
any dirt. For details, see "Inspecting Optical Fiber Connectors". If the fiber end
face is still dirty, repeat
Connect the fiber to the optical port immediately. If it is not used for the time
being, put a protective cap on it.
Turn on the laser after connecting the fiber to the board.
AC power supply mode: Under normal conditions, uninterruptible power
supply (UPS) obtains three-phase 380 V AC power input from a mains power
outlet and transmits 380 V AC power to an AC power distribution frame. A
chassis receives power from the AC power distribution frame through the
power distribution unit (PDU) installed in the cabinet.

High-voltage (240 V) DC power supply mode: Under normal conditions, a
rectifier system obtains three-phase 380 V AC power input from a mains
power outlet and transmits 240 V DC power to a DC power distribution frame.
A chassis receives power from the DC power distribution frame through the
PDU installed in the cabinet/rack.
