• Power down all laser sources to the optical fiber or disconnect the remote
optical fiber end from the laser sources. The laser sources can be in a
central office, on subscriber premises, or in a remote location.
Working with power
When you install power feeds to the product input terminals or if you perform
routine power maintenance, make sure that you do the following:
• Read and understand the power procedures you are performing.
• Take the necessary precautions and use the appropriate insulated tools to
perform any tasks.
A continuously lit green LED at the faceplate on the PSU indicates that the
circuit pack is functioning correctly and is powered up. If the green LED on the
PSU circuit pack is lit, the power at the associated feeder is present and the
conditions can be assumed to be normal.
If the green LED on the Fan+OAM or Fan+OAMV2 is not lit, the possible
causes can include, but are not limited to:
• damaged or non-functional power supply unit
• damaged or non functional Fan+OAM or Fan+OAMV2 circuit pack
• feeder low voltage or power failure
• an over-current fail
The circuit breaker on the power supply unit is an electronic circuit breaker. A
circuit breaker cuts off the power to the circuit pack on high current condition.
WARNING
Risk of electrical shock
The battery feeds can be at a high enough potential to
constitute a shock hazard. Read and understand the power
procedures you are performing. Take necessary precautions
and use the appropriate insulated tools when working with
power.
WARNING
Risk of personal injury, energy hazard
The battery feeds are capable of supplying very high current
which, during an unintentional short, can cause burns. Read
and understand the power procedures you are performing.
Take necessary precautions and use the appropriate insulated
tools when working with power.
