Floor Loading Considerations
Ensure that the floor under the rack supporting the Cisco 1000 Series Routers is capable of supporting
the combined weight of the rack and all other installed equipment.
To assess the weight of the fully configured Cisco 1000 Series Router respectively, refer to
Table 5-4
.
For additional information about floor loading requirements, consult the document

Site Power Guidelines
The Cisco 1000 Series Router has specific power and electrical wiring requirements. Adhering to these
requirements ensures reliable operation of the system. Follow these precautions and recommendations
when planning your site the Cisco ASR 1000 Series Router:
•
The redundant power option provides a second, identical power supply to ensure that power to the
chassis continues uninterrupted if one power supply fails or input power on one line fails.
•
In systems configured with the redundant power option, connect each of the two power supplies to
a separate input power source. If you fail to do this, your system might be susceptible to total power
failure due to a fault in the external wiring or a tripped circuit breaker.
•
To prevent a loss of input power, be sure the total maximum load on each circuit supplying the power
supplies is within the current ratings of the wiring and breakers.
•
Check the power at your site before installation and periodically after installation to ensure that you
are receiving clean power. Install a power conditioner if necessary.
•
Provide proper grounding to avoid personal injury and damage to the equipment due to lightning
striking power lines or due to power surges. The chassis ground must be attached to a central office
or other interior ground system.
Caution
This product requires short-circuit (overcurrent) protection, to be provided as part of the building
installation. Install only in accordance with national and local wiring regulations.
Note
The Cisco 1000 Series Router installation must comply with all applicable codes and is approved for use
with copper conductors only. The ground bond fastening hardware should be of compatible material and
preclude loosening, deterioration, and electrochemical corrosion of hardware and joined material.
Attachment of the chassis ground to a central office or other interior ground system must be made with
an AWG #6 gauge wire, copper ground conductor at a minimum.
Electrical Circuit Requirements
Each Cisco 1000 Series Router requires a dedicated electrical circuit. If you equip it with dual power
feeds, provide a separate circuit for each power supply to avoid compromising the power redundancy
feature.
The Cisco ASR 1000 Series Routers can be powered by a DC or AC source. Ensure that the equipment
grounding is present and observe power strip ratings. Make sure that the total ampere rating of all
products plugged into the power strip does not exceed 80% of the rating.
Table 5-5
contains specifications for DC-powered systems for all Cisco ASR 1000 Series Routers.
