If the power supply voltage does not meet requirements, do not power on
the device.
Check whether fixed optical attenuators have been added in accordance
with corresponding configuration rules.
Check whether the fuse capacity of the external power supply meets re-

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 o, contact software
commissioning engineers to
replace the board.
Before performing a power-on check,
