Troubleshooting Shelves
SH1HU-F/2DC, SH1HU-HP/2DC, and SH1HU-HP/E-
TEMP/2DC Power Status LEDs
Power redundancy is achieved by two separate power inputs labeled “pwr 1” and “pwr 2” 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.
Please follow the troubleshooting steps in Table 3 based upon the states of the LEDs.
Note
If your module has a power LED status that is not represented in Table 3, please contact your
ADVA Optical Networking Technical Services Representative.

Potential Cause Solution for Troubleshooting
pwr1 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.
pwr2 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.
