Table 13: SH9HU and SHX9HU Slot Status LEDs
SH9HU and SHX9HU Network Element Status LEDs
There are three NE LEDs on the CEM/9HU front panel of SH9HU and SHX9HU shelves:
• Critical
• Major
• Minor
Note
The NE Status LEDs (critical, major, minor) are active only on the master shelf, i.e. only once for
a network element. The NE status LEDs of the remaining shelves within the network element
will be off.
The three LEDs indicate a failure of the network element. Only the highest failure level within the NE will be
indicated. Therefore, only one of the three LEDs is lit red, yellow or is off at any given time. The three LEDs are lit
green when no failures exist at the NE. Table 14 addresses LEDtroubleshooting guidelines for the SH9HU and
SHX9HU NEstatus LEDs.
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
If your module has an LED status that is not represented in Table 14, please contact your ADVA
Optical Networking Technical Services Representative.
