The distance between the center lines of the mounting holes on the two mounting posts must be 18.31 in. ±
0.06 in. (46.50 cm ± 0.15 cm). The rack-mounting hardware included with the chassis is suitable for most
19-in. (48.3-cm) equipment racks.
Consider installing the Cisco ASR 1001-HX Router or Cisco ASR 1002-HX Router in a rack with the following
features:
•
NEBS-compliant, 19-in. (48.3-cm) wide rack.
•
EIA or ETSI hole patterns in the mounting rails. Required mounting hardware is shipped with the Cisco
ASR 1001-HX Router and Cisco ASR 1002-HX Router. If the rack that you plan to install the system
in has metric-threaded rails, you must provide your own metric-mounting hardware.
•
Perforated top and open bottom for ventilation to prevent overheating.
•
Leveling feet for stability.
The Cisco ASR 1001-HX Router and Cisco ASR 1002-HX Router should
not
be installed in an enclosed
rack because the chassis requires an unobstructed flow of cooling air to maintain acceptable operating
temperatures for its internal components. Installing the router in any type of enclosed rack
—
even with the
front and back doors removed
—
could disrupt the air flow, trap heat next to the chassis, and cause an
overtemperature condition inside the router. If you use an enclosed rack, make certain that there are air
vents on all sides of the rack and there is proper ventilation.
Note
Guidelines for 23-in. (Telco) Racks
If needed, you can also install the Cisco ASR 1001-HX Router and Cisco ASR 1002-HX Router in 23-in.
(Telco) racks. For information on the adapters needed for 23 in. racks, contact the Newton Instrument Company:

Equipment Rack Guidelines
The placement of racks can affect personnel safety, system maintenance, and the system
’
s ability to operate
within the environmental characteristics described in
Table 7: Cisco ASR 1001-HX Router and Cisco ASR
1002-HX Router Environmental Tolerance , on page 35
. Choose a proper location for the Cisco ASR 1001-HX
Router and Cisco ASR 1002-HX Router by following the guidelines below.
Locating for Safety
If the Cisco ASR 1001-HX Router and Cisco ASR 1002-HX Router is the heaviest or the only piece of
equipment in the rack, consider installing it at or near the bottom to ensure that the rack
’
s center of gravity is
as low as possible.
For additional information about the proper placement of electronic equipment, see the document
