Internal cable routing and connectors
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.
Hot-swap hard disk drive backplane cable connections
The following illustration shows the internal routing for the hot-swap hard disk drive
backplane cables.
Notes:
1. To connect the hot-swap backplane signal cables, make sure that you first
connect the signal cable, and then the power cable.
2. The signal cables are always disconnected first, and then the power cable and
the hot-swap backplane signal cable.
3. Make sure the longer signal cable connects to Port 0 and the shorter signal
cable connects to Port 1 on the ServeRAID-M1015 adapter.

3.5-inch SAS/SATA hot-swap hard disk drive bays.
