4.2.3 Attention for HDD Installation
(1) In case of steel plate installation on HDD cover side, the spacing between
HDD cover and steel plate should be kept more than 2 mm. If this spacing is not
kept for the steel plate, it may affect Load/Unload mechanism.
(2) The PCBA side of the drive should be covered with insulation sheet if the active
metal of host system may contact to the PCBA of the drive. If the insulation
sheet
is not provided for the possible contact of the live metal, failures may occur.
(3) Do not push the bottom PCBA. It may cause catastrophic failures.
4.3 Device Address Setting (DRIVE 0/DRIVE 1)
When the device is connected to the host bus, Device address setting is necessary to configure
a device as DRIVE 0 or DRIVE 1. The device address setting is established between drives on
the interface connector by using jumper 0-2 (pin # A, B, D)
The DRIVE 0 is assigned to device address 0, and the DRIVE 1 is assigned to device address 1.
