15.1 Connector
IDE interface 1 is available through Connector X4 (39 pins).
This interface is designed in 0.1" grid for optimal connectivity
to a 3.5" hard drive. IDE interface 2 is available through
Connector X6 (44 pins.) It is designed in a 2mm grid for optimal
connectivity to a 2.5" hard drive.
There are several accessories available for IDE interface 2
connectivity.
You can use two cables to directly connect a hard disk in a 2.5"
form factor (KAB-IDE-2MM, Part Number 96021-0000-00-0) or a 3.5"
form factor (KAB-IDE-25, Part Number 96020-0000-00-0).
