To check the installation of a TRSA: 
1. Make sure that the power-on LED (green light) is on.
Figure 3-9
 on page 3-24 shows the location of the power-on LED and fault LED.
2. If the power-on LED (green light) does not come on, do one or both of the following 
steps:
a. Reseat the TRSA.
b. Check the TRSA and backplane connector for damaged pins.
Note the Following Error Conditions
•
If the power-on LED does not come on after you reseat the TRSA, you must replace 
the TRSA
•
If the TRSA or backplane connector have damaged pins, both the TRSA and 
backplane (or enclosure) must be replaced. For backplane replacement instructions, 
refer to the Himalaya S-Series Service Provider Supplement.
Note. When the adapter is inserted, the fault LED (yellow) remains on until the service 
processor has completed its start-up configuration; the fault LED also turns on when a 
POST failure is detected.
