Troubleshooting Shelves
SH1HU-R(/PF) Power Status LEDs
Power redundancy is achieved by two separate power inputs labeled “PSU1“and “PSU2” left to the shelf display
on the front panel. In this case, power should be received from two independent power sources. If one of the two
power feeds fails, the power supply will continue to provide the required power to the shelf until the fault is
cleared.
This shelf uses the PSU/1HU-R-AC(-200) as power source. This PSU has a single tri-color LED indicator
marked “P” on its faceplate providing more detailed information on the operational status of the unit. Refer to
“PSU/1HU-R-AC and PSU/1HU-R-DC-200” on p.89 for more information.
Please follow the troubleshooting steps in Table 7 on p.72 based upon the states of the LEDs.
Note
If your module has a power LED status that is not represented in Table 7 on p.72, please contact
your ADVA Optical Networking Technical Services Representative.

Potential Cause Solution for Troubleshooting
PSU1 Red An overload of circa 110% is reached. A hardware error has occurred. Return the
SH1HU shelf to ADVA Optical
Networking.
This unit is not receiving DC power,
but the redundant power feed provides
power to the shelf.
Yellow The maximum output power is reached
or exceeded.
Check the power connection according to
the SH1HU power supply specification.
Off DC power source connected to power
feed 1 has failed.
1 Check the power connection. If power
connection is OK, a hardware error
has occurred.
2 Return the shelf to ADVA Optical
Networking.
If the polarity for connecting the power
cord has not been considered, connect the
power supply to a system safety ground
lead.
Green The unit is receiving DC power through
power feed 1.
No action is required.
The input voltage is in the admissible
range.
