Replacing a TRSA CRU

Checking the Installation of a TRSA CRU
1 Make sure that the power-on LED (green light) is on.
Note: The fault LED (amber light) flashes when the Token-Ring
ServerNet adapter (TRSA) CRU is installed and continues to flash while the
condition of the TRSA CRU is tested. The test that is executed is the
power-on self-test (POST). The fault LED goes off when the POST
successfully finishes.
The figure shows the location of the power-on LED and fault LED.
2 If the power-on LED does not come on, one or more of the POST tests might
not have passed or the POST was never started. Do one or both of the
following:
Reseat the TRSA CRU.●
Check the TRSA CRU and backplane connector for damaged pins.●
If the power-on LED does not come on after you reseat the TRSA CRU, you
must replace the TRSA CRU. Click here to return to the beginning of this

If the TRSA CRU or backplane connector have damaged pins, both the
TRSA CRU and backplane (or enclosure) must be replaced. For TRSA CRU

backplane replacement instructions, see the NonStop S-Series Service
Provider Supplement in the Hardware Service and Maintenance library.
