Planning Your Installation

Before you install your Cisco VG224 voice gateway, consider the information in this chapter:

???Location and Mounting Requirements, page 2-1

???Distance Limitations for Interface Cables, page 2-5

???Interference Considerations, page 2-5

Location and Mounting Requirements

The three mounting possibilities for your Cisco VG224 voice gateway are as follows:

???Rack-mount

???Wall-mount

???Bench-top

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

The installation location (room, closet, or cabinet) for the Cisco VG224 should always be well ventilated and provide adequate air circulation to ensure proper cooling. The room temperature should be maintained from 32 to 122??F (0 to 50??C).

Note The Cisco VG224 voice gateway chassis is designed for front-to-back airflow.

Cisco VG224 Voice Gateway Hardware Installation Guide

Chapter 2 Planning Your Installation

Location and Mounting Requirements

Enclosed Racks

Caution Enclosed racks must have adequate ventilation. An enclosed rack should never be overcrowded and should have louvers and a fan.

If the Cisco VG224 voice gateway 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.

If the chassis is installed using slide rails, check for blocked ventilation ports when it is in position in the rack or cabinet. Make sure that the ventilation ports of the Cisco VG224 voice gateway 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 different equipment arrangements.

Wall-Mounted

If the Cisco VG224 voice gateway is installed on a wall, there should be plenty of space on both sides to ensure that there is adequate air flow through the chassis.

Bench-Mounted

If the unit is placed on a bench-top, do not stack other equipment or paper on the chassis. Provide plenty of space for air circulation (front to back). Inadequate ventilation can result in overheating and damage.

Access to Chassis

Allow space at the rear 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, refer to the ???Installing the Ground Connection??? section on page 3-11.

Cisco VG224 Voice Gateway Hardware Installation Guide

Chapter 2 Planning Your Installation

Location and Mounting Requirements

Power Source

A Cisco VG224 voice gateway with AC power supply autoselects either 100???127 volt or 200???240 volt operation. AC versions 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.)

Caution The Cisco VG224 voice gateway 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???if lights flicker often or there is machinery with large motors nearby???have a qualified person test the power. Install a power conditioner if necessary.

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

Statement 1001

Warning Read the installation instructions before you connect the system to its power source. Statement 1004

Warning This product relies on the building???s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than:120 VAC, 15A U.S. (240 VAC, 10A international) Statement 1005

Warning The device is designed for connection to TN and IT power systems. Statement 1007

The +12V DC Input Power Supply

The +12V DC power connector to use with the Cisco VG224 voice gateway is the Molex Mini-Fit Jr. 5557 series, 8 circuit dual row (Molex P/N 39-01-2085). The VG224 +12V DC power input was designed to be used with an external UPS system, and it has status signals that are reported to the VG224.

Table 2-1 shows the connector pin assignment for the +12V DC power connector pin assignment.

Chapter 2 Planning Your Installation

Distance Limitations for Interface Cables

Cable Types

The cable types that are used are dependent on the Cisco VG224 voice gateway that you are using. For more information, see the ???Interfaces and Service Capabilities??? section on page 1-4 and Appendix A, ???Cable Specifications and Information.???

???Fast Ethernet cables (RJ-45-to-RJ-45 straight-through cables)

???Analog voice cables (RJ-21)

Distance Limitations for Interface Cables

When planning your installation, consider distance limitations and potential electromagnetic interference (EMI) as defined by the Electronic Industries Association (EIA). Distance limitation information is included for the following VG ports:

???Fast Ethernet Maximum Distance, page 2-5

???FXS Analog Voice Port Maximum Distance, page 2-5

Fast Ethernet Maximum Distance

The maximum segment distance for Fast Ethernet is 330 feet (100 meters) (specified in IEEE 802.3).

FXS Analog Voice Port Maximum Distance

The maximum distance is established by a total allowable loop resistance, including the phone or terminal equipment, of 600 ohms.

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 the installation of terminal plant cabling:

???Unshielded plant cabling can emit radio interference.

???Strong electromagnetic interference (EMI), especially as caused by lightning or radio transmitters, can destroy the EIA/TIA-232 drivers and receivers in the Cisco VG224 voice gateway.

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 exceeding 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.

Most data centers cannot resolve the infrequent, but potentially catastrophic problems just described without pulse meters and other special equipment. Take precautions to avoid these problems by providing a properly grounded and shielded environment and by installing electrical surge suppression.

EIA/TIA-232 Connections

The EIA/TIA-232 standard supports unbalanced circuits at signal speeds up to 64 kbps.

For connection to a Cisco VG224 voice gateway serial port, use the EIA/TIA-232 serial transition cable with the Cisco 12-in-1 connector on one end and a DB-25 connector (as shown in Figure A-7) on the other. The DB-25 connector can be male for DTE or female for DCE. To order a cable, see the ???Obtaining Technical Assistance??? section on page 16.

Figure A-7 EIA/TIA-232 Serial Transition Cable Connectors

EIA/TIA-449 Connections

The EIA/TIA-449 standard, which supports balanced and unbalanced transmissions, is a faster (up to 2 Mbps) version of the EIA/TIA-232 standard that provides more functions and supports transmission over greater distances.

The EIA/TIA-449 standard was intended to replace the EIA/TIA-232 standard. However, this standard was not widely adopted because of the large installed base of DB-25 hardware. Also, the larger size of the 37-pin EIA/TIA-449 connectors limited the number of connections possible (fewer than are possible with the smaller, 25-pin EIA/TIA-232 connector).

To make a connection to a Cisco VG224 voice gateway serial port, use the EIA/TIA-449 serial transition cable with the Cisco 12-in-1 connector on one end and a DB-37 connector (as shown in Figure A-8) on the other. The DB-37 connector can be male for DTE or female for DCE. To order a cable, see the ???Obtaining Technical Assistance??? section on page 16.

X.21 Connections

The X.21 connector uses a 15-pin connector for balanced circuits and is commonly used in the

United Kingdom to connect to the public data network. X.21 relocates some of the logic functions to the DTE and DCE interfaces and, as a result, requires fewer circuits and a smaller connector than EIA/TIA-232.

Use the X.21 serial transition cable (not included) with the Cisco 12-in-1 connector on one end and a DB-15 connector (as shown in Figure A-10) on the other. The DB-15 connector can be male for DTE or female for DCE. To order a cable, see the ???Obtaining Technical Assistance??? section on page 16.

EIA/TIA-530 Connections

The EIA/TIA-530 standard, which supports balanced transmission, provides the increased functionality, speed, and distance of EIA/TIA-449 on the smaller, DB-25 connector used for EIA/TIA-232. Like EIA/TIA-449, EIA/TIA-530 refers to the electrical specifications of EIA/TIA-422 and EIA/TIA-423. Although the specification recommends a maximum speed of 2 Mbps, EIA/TIA-530 is used successfully at 4 Mbps or faster speeds over short distances. Cisco VG224 voice gateway supports speeds up to 2.048 Mbps.

Use the EIA/TIA-530 serial transition cable (not included) with the Cisco 12-in-1 connector on one end and a DB-25 connector (as shown in Figure A-11) on the other. The DB-25 connector can be male for DTE or female for DCE. To order a cable, see the ???Obtaining Technical Assistance??? section on page 16.
