Chassis Installation
• Mount the bottom of the first base station chassis assembly
approximately 5.25 inches (13.3 cm) above the bottom of the
rack or cabinet.
• Install additional base station chassis, one above the other, sep-
arated by a single RU (1.75 inch/4.4 cm) blank panel between
them.
• Secure the base station chassis and blank panels with the
machine screws provided by the rack or cabinet manufacturer.
Power and Grounding System
The base station chassis is normally shipped with the A bus
ground stud internally connected to chassis ground and the B bus
ground stud internally connected to digital ground. A removable
metal jumper bridges chassis and digital ground is on the
backplane.
