Table 4. J5 Connector pinout
To install the hard disk, perform the following operations:
1. Install the hardware
Connect the hard disk to the module using a data cable, and then connect the hard disk to the
power supply according to the device’s specifications. Make sure that pin 1 of connector J5 and
pin 1 of the drive or drives are correctly connected. Pin 1 of the interface cable is usually indicated
by a stripe along the edge of the cable. If two hard disks need to be connected, they must be
configured for common operation (i.e. master/slave or cable select connection)
2. Configure the IDE BIOS setup
Hard disk parameters can be configured using the Setup program. If the hard disk is connected to
the module without the correct setup configuration (BIOS or Hardware), a time-out of a few
minutes may occur
3. Perform a software initialization (for specific operating systems)
Refer to the OS documentation
