Align the fan tray connector and the backplane
connector.

Gently push the fan tray inward until the connectors
engage.
You feel a slight resistance as the connectors engage.
CAUTION:
If the resistance is too great, the fan tray
connector and backplane connector may not be
aligned properly. Do not force the fan tray inward or
you can damage the connectors. If necessary, remove
and reinsert the fan tray, ensuring that the connectors
are properly aligned.
