2 Installation
This chapter describes only the mechanical installation of the drive unit. For the
mechanical installation of the power supply unit, see "810 Series Power Supply Unit
User Guide".
2.1 Cabinet Design
2.1.1 Clearance Requirements
The MD810 units comprise of:
■
"Booksize format" with common height for power supply and drive units (different
width: 50 mm, 100 mm, 200 mm, 300 mm)
■
Larger rating power supply unit in "vertical tower format" whose dimensions (180
mm and 230 mm width) are larger than the booksize format
Single and dual rack installation is supported for the MD810 series drive unit. When
installing two racks of booksize units, one above the other, as shown in Figure 2-1,
observe the recommended air clearance distances between the top and bottom racks
(see the following table for details) and install an air guide plate to allow for proper heat
dissipation to avoid overheating the top rack.
