Replacing an ATM3SA CRU

Checking the Installation of an ATM3SA CRU
1 Make sure that the power-on LED (green light) is on.
Note: The fault LED (amber light) flashes when the ATM ServerNet
adapter (ATM3SA) CRU is installed and continues to flash while the
condition of the ATM3SA 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 ATM3SA CRU.●
Check the ATM3SA CRU and backplane connector for damaged
pins.
●
If the power-on LED does not come on after you reseat the ATM3SA CRU,
you must replace the ATM3SA CRU. Click here to return to the beginnning

If the ATM3SA CRU or backplane connector have damaged pins, both the
ATM3SA CRU and backplane (or enclosure) must be replaced. For
