Overview

The Cisco IAD2430 series IADs aggregate multiple channels of data and voice or fax user-side traffic

for transport over single or multiple WAN uplinks. Voice or fax traffic is transported by VoIP or by

Voice over Asynchronous Transfer Mode (VoATM). All platforms support Media Gateway Control

Protocol (MGCP), the signaling protocol H.323, and Session Initiation Protocol (SIP).

The Cisco IAD2430, Cisco IAD2431, and Cisco IAD2432 series routers consist of five models with a

common front panel (Figure 1). The Cisco IAD2435 series router consists of one model

(Cisco IAD2435-8FXS) with a different front panel (Figure 2). The Cisco IAD2430, Cisco IAD2431,

and Cisco IAD2432 series routers include a slot for the external flash memory card, as well as console,

auxiliary, and flash (CF) memory ports. The front panel, labeled “Cisco IAD2400 Series,” is identical

for all models. However, the back panels, labeled by specific model number, vary considerably,

depending on interfaces, ports, and options. Analog voice ports use an RJ-21 interface.

C H A P T E R

Planning Your Installation

Before you install your Cisco IAD2430 series integrated access device (IAD), see the information in this

chapter:

•

Location and Mounting Requirements, page 2-1

Distance Limitations for Interface Cables, page 2-4

Interference Considerations, page 2-6

Location and Mounting Requirements

The three mounting possibilities for your Cisco IAD are as follows:

•

Rack mounting

Wall mounting

Desktop mounting

The mounting location must provide the following:

•

Access to the chassis

Access to a suitable power source

Access to an appropriate earth ground

Allowance for adequate heat dissipation and airflow around the chassis

Temperature Control and Ventilation

For proper cooling, the installation location (room, closet, or cabinet) for the Cisco IAD2430 series IAD

should always be well ventilated and provide adequate air circulation. The room temperature should be

maintained at from 32 to 122°F (0 to 50°C).

Note

The Cisco IAD2430, IAD2431, and IAD2432 series IAD chassis is designed for front-to-back airflow.

Rack-Mounted Installation

If the Cisco IAD is installed in an enclosed rack with a ventilation fan at the top, make sure that heated

air drawn upward from other equipment does not prevent adequate cooling.

Cisco IAD2430 Series Integrated Access Devices Hardware Installation Guide

OL-4234-06

2-1

Chapter 2 Planning Your Installation

Location and Mounting Requirements

Caution

Enclosed racks must have adequate ventilation. An enclosed rack should never be overcrowded and

should have louvers and a fan.

If you install the chassis by using slide rails, check for blocked ventilation ports when the chassis is

positioned in the rack or cabinet. Make sure that the ventilation ports of the Cisco IAD are not blocked.

Tip

Baffles can help isolate exhaust air from intake air. Baffles also help draw cooling air through the

cabinet. The best location for the baffles depends on the airflow patterns in the rack. You can test the

airflow by experimenting with various equipment arrangements.

Wall-Mounted Installation

If you install the Cisco IAD on a wall, there should be plenty of space on both sides for adequate airflow

through the chassis.

Desktop Installation

If you place the unit on a desktop, do not stack other equipment or paper on the chassis. Allow plenty of

space for air circulation (front to back). Inadequate ventilation can result in equipment overheating and

damage.

Access to Chassis

Allow space at the back of the chassis for cable connections. Also consider the need to access the chassis

for future upgrades, maintenance, and troubleshooting.

Chassis Grounding

Chassis grounding is provided through the power cable, which uses a standard grounding plug. However,

the chassis also requires a reliable earth ground, using the earth ground lug and hardware provided. For

more information, see the “Installing the Ground Connection” section on page 3-14.

Power Source

A Cisco IAD2430 series IADs with AC power supply autoselects either 100- to 127-V or 200- to 240-V

operation. The Cisco IADs with AC power supply include a 6-foot (1.8-meter) electrical power cord. (A

label near the power cord indicates the correct voltage, frequency, current draw, and power dissipation.)

The Cisco IAD2435 IAD connects to a 60-W, 12-VDC power adapter with the following specifications:

•

Input voltage—85 to 264 VAC

Input frequency—47 to 63 Hz

Power output—60 W maximum

Output voltage—+12 VDC

Chapter 2 Planning Your Installation

Location and Mounting Requirements

Caution

The Cisco IAD2430 series chassis provides inputs for both AC and DC power. Design your installation

to use only one type of power. Do not use AC and DC power at the same time. If you do, the unit stops

operating, and you need to reboot it with only a single power source.

If you suspect that your AC power is not clean—for example, if lights flicker often or if there is

machinery with large motors nearby—have a qualified person test the power. Install a power conditioner

if necessary.

Please read all the warnings and cautions before applying power to your Cisco IAD.

FXS Analog Voice Port Maximum Distance

The maximum distance for a Foreign Exchange System (FXS) is established by a total allowable loop

resistance, including off-hook phone or terminal equipment, of 600 ohm. The maximum distance is

100 meters away from the system as a limitation of Ethernet.

FXO Analog Voice Port Maximum Distance

The maximum distance is determined by the distance between the PBX or other equipment that provides

battery and the connection to the FXO voice port.

Interference Considerations

When you run cables for any significant distance in an electromagnetic field, interference can occur

between the electromagnetic field and the signals on the cables. This has two implications for

installating terminal plant cabling:

•

Unshielded plant cabling can emit radio interference.

Strong electromagnetic interference (EMI), especially that caused by lightning or radio transmitters,

can destroy the EIA/TIA-232 drivers and receivers in the Cisco IAD.

If you use twisted-pair cables with a good distribution of grounding conductors in your plant cabling,

emitted radio interference is unlikely.

If you have cables that exceed the recommended distances, or if you have cables that pass between

buildings, give special consideration to the effect of lightning strikes or ground loops. If your site has

these characteristics, consult experts in lightning suppression and shielding. The electromagnetic pulse

caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded

conductors to destroy electronic devices.

Without pulse meters and other special equipment, most data centers cannot resolve the infrequent but

potentially catastrophic problems just described. Take precautions to avoid these problems by providing

a properly grounded and shielded environment and by installing electrical surge suppression.

If you remove any module, you must either install a module in its place or install a cover plate over the

opening. All module openings must be either occupied or covered to prevent electromagnetic

interference.

For advice on the prevention of electromagnetic interference, consult experts in radio frequency

interference (RFI).

Safety Recommendations

The following information is included to alert you to safety recommendations and best practices when

working with this equipment.

Maintaining Safety with Electricity

Follow these guidelines when working on equipment powered by electricity.

Warning

Do not work on the system or connect or disconnect cables during periods of lightning activity.

Statement 1001

Blank faceplates and cover panels serve three important functions: they prevent exposure to

hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)

that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not

operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement

1029

General Safety Practices

Follow these guidelines to ensure personal safety and protect the equipment:

•

Keep the chassis area clear and dust-free during and after installation.

Put the removed chassis cover in a safe place.

Keep tools away from walk areas where you and others could fall over them.

Do not wear loose clothing that could get caught in the chassis.

Wear safety glasses if you are working under any conditions that might be hazardous to your eyes.

Warning

This equipment must be installed and maintained by service personnel as defined by AS/NZS 3260.

Incorrectly connecting this equipment to a general-purpose outlet could be hazardous. The

telecommunications lines must be disconnected 1) before unplugging the main power connector or 2)

while the housing is open, or both. Statement 1043

Safety Tips

Use these tips as safety guidelines when installing or working around this equipment.

•

Locate the emergency power-off switch for the room in which you are working. Then, if an electrical

accident occurs, you can act quickly to turn off the power.

•

Disconnect all power before installing or removing a chassis.

Do not work alone if potentially hazardous conditions exist.

Never assume that power is disconnected from a circuit. Always check.

Chapter 3 Installing Cisco IAD2430 Series IADs

Site Log

•

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power

extension cables, and missing safety grounds.

If an electrical accident occurs, proceed as follows:

–

Use caution; do not become a victim yourself.

Turn off power to the system.

If possible, send another person to get medical aid. Otherwise, assess the condition of the victim

and then call for help.

–

Determine if the person needs rescue breathing or external cardiac compressions; then take

appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD occurs when

electronic components are improperly handled; it can result in complete or intermittent failures.

Always follow ESD-prevention procedures when removing and replacing components.

•

Ensure that the chassis is electrically connected to earth ground.

Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact.

Connect the clip to the ESD-strap connection jack (to the left of the power switch on the back of the

chassis) or to an unpainted chassis frame surface.

Caution

For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and

10 megohm (Mohm).

Chapter 3 Installing Cisco IAD2430 Series IADs

Installing the Ground Connection

Warning

The importance of proper grounding cannot be overemphasized. It will minimize the potential for

damage to your system and maximize safety at the system site. We recommend you consult a licensed

electrician or your local electric utility company if you have any questions. Statement 269

A ground wire must always be a single piece of wire. Never splice two wires together for a ground.

Corrosion and weathering can lead to a poor connection at the splice, making the ground ineffective

and dangerous. Statement 270

Warning

Use copper conductors only. Statement 1025

Installation of the equipment must comply with local and national electrical codes. Statement 1074

You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance

with local electrical safety standards.

•

For NEBS-compliant grounding, use size AWG 6 (13 mm²) wire and the ground lug provided in the

accessory kit.

For NEC-compliant grounding, use size AWG 14 (2 mm²) or larger wire and an appropriate

user-supplied ring terminal.

For EN/IEC 60950-compliant grounding, use size AWG 18 (1 mm²) or larger wire and an

appropriate user-supplied ring terminal.

To ground the chassis, follow these steps:

Step 1

Tip

Locate a suitable ground location.

Use a multimeter to measure the resistance between various ground locations, such as the following:

•

Between the ground of a junction box (outlet) and the ground of a power tap

Between the ground of a junction box and a metal water pipe

Between the Cisco IAD chassis and the ground of a power tap

Between the Cisco IAD chassis and the ground of a junction box

A good ground connection should read between 0.0 and 0.5 ohm.

Step 2

Step 3

Strip one end of the ground wire to the length required for the ground lug or terminal.

•

For the NEBS ground lug—approximately 0.75 inch (20 millimeters)

For user-provided ring terminal—as required

Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size. (See

Figure 3-13.)

the protective device is rated not greater than: 120 VAC, 15A (240 VAC, 10A international) Statement

1005

Warning

To prevent accidental discharge in the event of a power line cross, route on-premise wiring away

from power cables and off-premise wiring, or use a grounded shield to separate the on-premise

wiring from the power cables and off-premise wiring. A power line cross is an event, such as a

lightning strike, that causes a power surge. Off-premise wiring is designed to withstand power line

crosses. On-premise wiring is protected from power line crosses by a device that provides

overcurrent and overvoltage protection. Nevertheless, if the on-premise wiring is in close proximity
