Troubleshooting Shelves
SH1HU-F/2DC, SH1HU-HP/2DC, and SH1HU-HP/E-
TEMP/2DCSlot Status LEDs
These shelves have four slot LEDs each, one LED per slot. The slot LEDs indicate the operating status of the
inserted modules and the communication status to the management.
Each slot has its corresponding LED as follows:
• “A” and “B” indicate the operating status of the half-sized modules SCU or SCU-S and NCU.
• “1” and “2” indicate the communication status of the respective module to the SCU or SCU-S and NCU.
If the LED of the operating module is lit green, the module is working properly and there is no failure. If the LED is
lit yellow, red, or off, the module has a failure or does not work.
Table 2 on p.64 describes the cause of the status that each color of the LED indicator represents and if it
indicates a failure. This table also lists troubleshooting guidelines.
Note
Before you start with troubleshooting, ensure that the NEis operating with the required NCU
software and module firmware. For details on updating NCU software and module firmware,
refer to “Updating the NE Software Release” on p.617 and “Performing Other Software Update
Actions” on p.628.
Note
Before you start with troubleshooting be sure that the admin status on the affected module is set
to “Maintenance”.
Note
If your module has an LED status that is not represented in Table 2 on p.64, please contact your
ADVA Optical Networking Technical Services Representative.
