Statement 1030
Warning
Watch your hands and fingers whenever you handle the chassis, modules, compute nodes, and components!
Narrow vertical or horizontal spaces in situations like, but not limited to, moving the chassis into or out of
the shipping container or equipment rack can cause pinch hazards for your hands and fingers.
Although they do not eliminate the possibility of pinching, the chassis has defined grasp points to facilitate
handling and moving it. For information about chassis grasp points, see
Handling the Chassis, on page 4
Important
Do not lift or handle the chassis by the top rear sheet metal, as indicated by the DO NOT LIFT label on the
top rear surface.
Note
Rack Requirements
This section provides the requirements for installing in a standard open rack, assuming an external ambient
air temperature range of 41 to 95°F (5 to 35°C):
Do not use racks that have obstructions. These obstructions could impair access to field-replaceable units
(FRUs).
Note
Cisco UCS is compliant with any EIA-310-D/E compliant rack. Your equipment racks must also be compliant
with EIA-310-D/E standard.
The Cisco UCS X9508 chassis can be installed in either a 9.5 mm square-hole rack or a 7.1 mm unthreaded
round-hole rack. These racks require either square-hole cage nuts or round-hole cage nuts (also called spring
nuts), respectively. Cage nuts and spring nuts are not provided by Cisco. They should have accompanied your
equipment rack. Use the proper cage nut or spring nut for your rack.
Some racks might be tapped, with threaded holes drilled directly into the rack's sheetmetal instead of square-
or round-hole punchouts for cage nuts. The rail kit for the server is not currently supported in tapped (threaded
hole) racks. Do not attempt to install the chassis in a tapped (threaded hole) equipment rack.
Caution
Also, be aware of these additional requirements:
• The tool-less rack-mount kits (either Type 1 or Type 2) shipped with the chassis are required. The
adjustable rack rails shipped with each enclosure extend from 29 inches (73.66 cm) to 35 inches (88.9
cm)
• Front and rear doors—If your compute node rack includes closing front and rear doors, the doors must
have 65 percent open perforated area evenly distributed from top to bottom to permit adequate airflow.
