3.7 Mounting
3.7.1 Checks before mounting the drive
Before mounting the optical disk drive in the system cabinet, check whether the jumper settings are
set correctly.
3.7.2 Mounting procedure
How the drive is mounted depends on the system cabinet structure. Determine the mounting
procedure in consideration of the requirements of each system. This section contains the general
mounting procedure and check items.
See Section 3.2 for details on mounting drive.
1) Tighten four mounting screws to secure the drive in the system cabinet.
# The drive has ten mounting holes (both sides: 3%2, bottom: 4). Secure the drive using the
four mounting holes on both sides or the bottom.
# Use mounting screws whose lengths are 3 mm or less from the external wall of the mounting
frame of the drive when they are tightened. (See Figure 3.6)
# When mounting with screws, the screw tightening torque should be 0.4 to 0.45Nm (4 to
4.6kgfcm).
# Be careful not to damage the parts on the PCA when mounting the drive.
2) After securing the drive, make sure that the drive does not touch the chassis of the system
cabinet. There must be at least 1.5 mm clearance between the drive and chassis. (See Figure
3.6)
3.8 Cable Connections
Use the following cables to connect the drive to the system. See Subsection 3.4.2 for details on the
connector positions and cable requirements.
# Power supply cable
# AT interface cable
# DC ground cable (if required)
The general procedure for cable connection and notes on connecting cables are given below. Pay
attention to the insertion direction of each cable connector.
1) Make sure that the system power is off.
2) Do not connect or disconnect any cable when the power is on.
1) Connect the DC ground cable (only if required to decrease ground noise).
2) Connect the power cables.
