Internal cable routing and connectors
The following illustration shows the internal routing and connectors for the two SAS
signal cables (in server models with eight SAS drive bays).
Notes:
1. To connect the SAS signal cables, make sure that you first connect the signal
cable, and then the power cable and signal cable.
2. To disconnect the SAS signal cables, make sure that you first disconnect the
power cable, and then the signal cable and configuration cable.
The SATA cable is a combination power and signal cable with a shared connector
on both ends. The following illustration shows the internal routing and connector for
the SATA cable.
Attention: To disconnect the optional optical drive cable, you must first press the
connector release tab, and then disconnect the cable from the connector on the
system board. Do not disconnect the cable by using excessive force. Failing to
disconnect the cable properly may damage the connector on the system board. Any
damage to the connector may require replacing the system board.
