Handling Procedure
1. Power on the peer chassis.
2. Check the peer board and
ensure that the transmit opti-
cal power of the board is
normal.
3. Check that fiber connections
are correct.
4. If there is no fixed optical
attenuator at the optical port,
check the fiber attenuation,
clean the fiber connector, and
replace damaged fibers until
the indicator turns green.
If the chassis is powered on
but all the indicators on the
board are off, contact software
commissioning engineers to
replace the board.
