Installing the Expansion Shelf

The TSG-3800X can be mounted on a standard 19-inch or 23-inch instrument rack.
Power and signal connections are through rear panel connectors. This section
provides instructions for installing the TSG-3800X.
Considerations
The expansion shelf occupies 10.5 inches (26.7 cm) of vertical rack space and a
depth of 12 inches (30.5 cm). A 1RU (1.75 inch) space is recommended but not
required when installing more than one TSG-3800 shelf.
Note: When you install an expansion shelf, note that the maximum
length of cable available for connecting the main shelf to the
expansion shelf is six feet (1.8 m).
Procedures
1. The expansion shelf mounts flush to the rack or at distances of two inches or five
inches from the front of the rack. Attach a mounting bracket (00476807-xxx-1) to
each side of the shelf. Align two columns (three holes per column) of the bracket
with the holes on the side of the shelf. Use 4-40 x 18LG screws for attaching the
mounting bracket. Ensure to attach both brackets at equal distances from the
front of the unit, as shown in
2. Mount the expansion shelf to the front of the rack rails with eight sets of #10
screws, flat washers, and locking washers. The hardware attaches to the rack
through the slots located on the front of both mounting brackets (four slots per
bracket).
