Installing the SSU-2000
Rack Mounting the SSU-2000
62 SSU-2000 User’s Guide 12713020-002-2 Revision D – April 2004
Ventilation Considerations
For proper ventilation, there should be at least 2 RU (3 inches, 7.6 cm) of free space
above and below the shelf.
Rack Mounting the SSU-2000
The SSU-2000 shelf, when installed, occupies 10.5 in (26.7 cm) of vertical rack
space, has a depth of 12 in (30.5 cm), and a width of 19 in (48.3 cm). When
installing more than one SSU-2000, each unit must have at least one inch (2.5 cm)
of clearance above and below to ensure proper cooling. There should be at least
three inches (7.6 cm) of free space below the bottom shelf. It is recommended that
at least one I/O adapter panel be inserted between each unit.
SSU-2000 Shelf
The shelves mount flush to the rack or at distances of either 2 inches (5.1 cm) or
5 inches (12.7 cm) from the front of the rack. An SSU-2000 rack mounting diagram
is shown in Figure 2-1.
1. Attach a mounting bracket to each side of the shelf by aligning two columns
(three holes per column) of the bracket with the holes on the side of the shelf.
Use suitable screws for attaching the mounting bracket. Ensure that both
brackets are attached at equal distances from the front of the shelf.
2. Mount the instrument to the front of the rack rails with the appropriate number of
screws and washers for the rack.
Caution: To maintain EMC compliance, use only properly shielded
cabling on all telecom signal wiring, including I/O, clocks, and
Ethernet connections. Ensure that connections are appropriately
grounded.
Caution: To avoid excessive heat build-up resulting in equipment
damage, provide proper ventilation and cooling of the equipment.
Caution: Failure to provide proper ventilation can result in excessive
heat build-up resulting in equipment damage. Symmetricom suggests
that you insert an I/O adapter panel between shelves. See
Figure
2-1
