You can set the chassis on a desktop or install it in a rack. Use the procedure in this section that best meets the needs of your network:

Setting the Chassis on a Desktop

Rack-Mounting the Chassis


Warning When installing the unit, the ground connection must always be made first and disconnected last. To see translations of the warnings that appear in the publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.



Warning This unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location. To see translations of the warnings that appear in the publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.


Setting the Chassis on a Desktop

The location of the chassis is extremely important for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. The following information will help you to plan the location of the chassis:

Plan for access to both front and rear panels of the chassis.

Ensure that the room where the chassis operates has adequate ventilation. Remember that electrical equipment generates heat. Ambient air temperature may not cool equipment to acceptable operating temperatures without adequate ventilation.

Attach the rubber feet as shown in Figure 3-1. Rubber feet are included in the accessory kit that shipped with your universal gateway.

Figure 3-1 Attaching the Rubber Feet

Rack-Mounting the Chassis

This section describes how to rack-mount the chassis. The universal gateway arrives with 19-inch rack-mount brackets and larger brackets for use with a 23- or 24-inch rack. (See Figure 3-2.)

The following information will help you plan your equipment rack configuration:

Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.

When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated in the rack.

Baffles can isolate exhaust air from intake air, which also helps to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can be found by experimenting with different configurations.

When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the equipment by itself, if possible. Power OFF other equipment in the rack (and in adjacent racks) to allow the unit under test a maximum of cooling air and clean power.

Install the chassis and external devices to which it will connect in a contiguous stack.


Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. To see translations of the warnings that appear in the publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Step 2 Strip a minimum 1/4 in. (0.625 cm) off the wire insulation to connect the stranded wires to the alarm connector. The maximum insulation strip length is 0.31 in. (0.78 cm).

Step 3 Secure the wires to the alarm connector with screws.


Caution The maximum tightening torque on the screws is 7 in.-lb (0.79 N-m).

Step 4 Connect the wires to strain relief clamps that are inserted into the holes in the ventilation grid.



Note See Appendix C "Cabling Specifications" for alarm port cable assembly and port pinouts.


Supplying Power

The power system is comprised of a fully redundant switching power supply with two AC (or two DC) inputs to the main power modules. Each input and output is 100 percent fully redundant, with dual fans for added reliability.

The output of each power module is rated at 300 watts (nonredundant mode), and is composed of four independent output voltages: 3.3V, 5V, 12V, and -12V. AC input units have power factor correction, and low Total Harmonic Distortion. Units that are in redundant mode run at one-half the power capability. If a power supply failure occurs, these units are capable of powering the complete system either at the input side or the DC load side. Power failures are reported through software SNMP alarm traps.

Check the power at your site to ensure that you are receiving "clean" power (free of spikes and noise). Install a power conditioner if necessary.

The universal gateway AC power supply includes the following features:

Full range operation—100 to 240 VAC.

All units include two 6-foot (1.8-meter) electrical power cords. (A label near the power inlets indicates the correct voltage, frequency, current draw, and power dissipation for the unit.)


Caution In a DC power supply installation, do not connect the 48 VDC Return to chassis ground at the Cisco AS5400. A single-point ground is recommended at the power distribution rack.


Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. To see translations of the warnings that appear in the publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.



Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). To see translations of the warnings that appear in the publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.



Warning The device is designed to work with TN power systems. To see translations of the warnings that appear in the publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
