stops blinking and stays OFF.
Removal Procedure
The following describes how to remove an AMC module from the ATCA-F120. The procedure
assumes that the ATCA-F120 is powered. If it is not powered, the steps regarding the blue LED
can be ignored and skipped.
1. Make sure you are in an ESD safe environment.
2. Remove any cables that are connected to the AMC module face plate connectors.
3. Gently pull the module latch outwards, approximately 3mm from its locked
position.
4. Wait for the blue LED to first perform short blinks, and then glow persistently.
Data Loss
Removing the blade with the blue LED still blinking causes data loss.
Wait until the blue LED is permanently illuminated, before removing the blade.
