To replace a fan tray:
Step 1 Orient the fan tray so that the inside connector is on top in order to mate with the
connector on the backplane.
Step 2 Align the fan tray with the slot guides. Slide the tray into the slot until the faceplate of
the fan tray is flush with the chassis back.
Step 3 Make sure the connectors engage.
Step 4 Secure the fan tray faceplate into place by tightening the captive screws.
Step 5 Verify the fan status LED on the SF/CPM.
