When a critical or major alarm occurs, an alarm sound is generated and the corresponding alarm indicator on the front panel flashes. You can turn the ALMCUT switch from ALMON to ALMCUT to mute the alarm sound.
CAUTION
l When the ALMCUT switch is in position ALMCUT, the audible alarm is completely muted,
and the equipment does not generate an audible alert even when a new alarm occurs.
l When the equipment is operating normally or after an alarm is cleared, set the switch to
position ALMON so that the audible and visual alarm can be reported in the case of a new fault.
1.2.2 Indicators
The front panel of the OptiX 155/622H has five indicators on the right side. The indicators are used to indicate the running status and alarms of the equipment.
For the meanings of the indicators, see Figure 1-3. For the detailed description of the indicators, see 12 Indicators.

1.3.1 Power Filter Board
The OptiX 155/622H can be configured with two types of power filter boards: -48 V power filter board and +24 V power filter board.
1.3.2 Fan Board and Air Filter
The fan board of the OptiX 155/622H is used to dissipate heat and the air filter is used to prevent dust from entering the equipment.
1.3.3 Board Area
The board area of the OptiX 155/622H houses service boards.
1.3.1 Power Filter Board
The OptiX 155/622H can be configured with two types of power filter boards: -48 V power filter board and +24 V power filter board.

Power interface Power switch
Power interface
Grounding terminal
As shown in Figure 1-4, there are two power input interfaces on the front panel of the POI/POU. Hence, the POI/POU can access two -48 V or +24 V power supplies at the same time. The two power supplies function as a mutual backup for each other. A grounding terminal is used to connect the PGND end of a power cable below the power input interface.
1.3.2 Fan Board and Air Filter
The fan board of the OptiX 155/622H is used to dissipate heat and the air filter is used to prevent dust from entering the equipment.
The fan board and air filter are shown in Figure 1-5. If the fan alarm indicators are on or a fan alarm (FAN_FAIL) is reported to the network management system (NMS), it indicates that at least one fan does not operate properly. In this case, check the fan board. Ensure that you clean the air filter once every two weeks.

DANGER
Do not look directly at an optical interface or a fiber interface. The laser beams inside the fiber can damage your eyes.
CAUTION
Wear an antistatic wrist strap when holding a board. To prevent the static discharge from damaging the board, ensure that the antistatic wrist strap is properly grounded.
CAUTION
l A level optical module cannot be directly connected to an optical attenuator. If an optical
attenuator is required, use the attenuator on the optical distribution frame (ODF) side.
l Add an attenuator when performing a hardware loopback to prevent very high optical power
from damaging the receive optical module. Insert the attenuator in the IN interface instead of the OUT interface.

Data and clock restoration module SDH overhead processing module Logic control module STM-16 STM-16 Cross-connect unit O/E conversion E/O SCC unit 5 V Fuse 5 V conversion Cross-connect unit Backplane
Receive Direction
The O/E converting module converts a received STM-16 optical signal into an STM-16 electrical signal and sends the STM-16 electrical signal to the data and clock restoration module. The R_LOS alarm signal can be detected in the O/E converting module. The data and clock restoration module restores the clock signal and sends the clock signal and the STM-16 electrical signal to the SDH overhead processing module. Then, the SDH overhead processing module extracts the overhead bytes from the received STM-16 signal and sends the payload signal to the cross-connect unit through the backplane. The R_LOF alarm signal, R_OOF alarm signal, and other alarm signals are detected in the SDH overhead processing module.
Transmit Direction
The SDH overhead processing module inserts the overhead bytes into the electrical signal sent from the cross-connect unit and sends the electrical signal to the E/O converting module. Then, the E/O converting module converts the STM-16 electrical signal into an STM-16 optical signal and sends the STM-16 optical signal to fibers for transmission.
