3-8 PDR100 Installation
Rack Slide Maintenance
The slide-out sections of the tracks do not require lubrication. The dark gray finish on
the tracks is a permanent lubricating coating. The track sections should be checked
periodically for build-ups of dust or foreign material that might cause them to bind.
Removing the Unit
CAUTION: Be sure all cables are disconnected from the PDR100 or PDX103 prior
to attempting to remove the unit.
WARNING: Both the PDR100 and the PDX103 are considered to be too heavy for
one person to remove. PDR100 exceeds 70 pounds when equipped with eight hard
disks. PDX103 weight is similar.
1. Loosen retaining screws and pull cabinet outward until all three slide sections
latch.
2. Press both track stop latch buttons (visible in the stop latch holes) and carefully
slide the cabinet free of the tracks.
Mounting the RS-422 Connector Panel and XLR100
The RS-422 Connector Panel and XLR100 Audio Bypass are designed to mount at
the back of the rack. They are held in place by four pan head screws. The RS-422
panel is one rack unit high with the mounting holes spaced 1.250 inches (3.175 cm)
apart. The XLR100 panel is two rack units high with holes spaced 3.000 inches (7.62
cm) apart. For rack hole spacing see Figure 3-7. This connector panel has no cooling
requirements; it contains all passive circuitry. The Audio Bypass Unit has no special
cooling requirements, but does require mains power to operate.
