Air Flow Guidelines for ETSI Rack Installation

To install a Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router in a 2-post or 4-post
rack, the front and rear doors of the cabinet must be removed. It is recommended that you maintain a minimum
clearance distance as mentioned below, at all times.

•

front clearance

—

12.7 cm

•

rear clearance

—

10 cm

If you are mounting the chassis in a 4-post enclosed cabinet, ensure that you have a minimum of 10 cm of
clearance on each side of the chassis.

Floor Loading Considerations

Ensure that the floor under the rack supporting the Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M,
ASR-920-24TZ-M Routers is capable of supporting the combined weight of the rack and all the other installed
equipment.

To assess the weight of a fully configured Cisco ASR 920 Series Router, see the

Cisco ASR 920-24SZ-IM,

ASR-920-24SZ-M, ASR-920-24TZ-M Router Specifications

table.

For additional information about floor loading requirements, see the

GR-63-CORE, Network Equipment

Building System (NEBS) Requirements: Physical Protection

document.

Site Power Guidelines

The Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router have 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 power for the Cisco ASR 920-24SZ-IM,
ASR-920-24SZ-M, ASR-920-24TZ-M 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.

•

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 that the total maximum load on each circuit supplying the
power supplies is within the current ratings of the wiring and the 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.

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.
