These include:
- Ethernet cables connected to the network ports 
- Rollover cable connected to the serial port 
- Power cables connected to the power supplies of the Pilot 
Note: Oracle Customer Support recommends labeling all cables connected to the Pilot so that they can be reconnected accurately to the Pilot after the replacement procedure is complete.
Important! Ensure that the Pilot is offline before removing the power cords.
Caution
When the 
Pilot is offline, power is still directed to the power supply fans in the 
Pilot. To completely power off the 
Pilot, you must disconnect the power cords from the back of the power supplies.
