2 Planning Your Installation

This section will deal with physical requirements of a MAX 4 installation such as:

?? Location and Mounting Requirements

?? Distance Limitations for Interface Cables

?? Interference Considerations

?? Safety Precautions

2.1 Basic Requirements

Before you begin the installation process, you will need:

?? A Net2Phone MAX 4 unit

?? A corded or cordless analog telephone and from one to seven ancillary phones

?? A Local Area Network (LAN) with a broadband connection which may not have proxy server caching

?? A PC or Mac workstation with any recent Web browser, connected to the LAN (for initial setup and administration)

?? A Net2Phone account number and PIN

2.2 Location and Mounting Requirements

The physical installation location must provide:

?? Adequate heat dissipation

?? Access to the chassis

?? A suitable power source

Make certain that your intended physical location will meet these requirements before you begin the installation.

2.3 Heat Dissipation

??The room where the MAX 4 is operated must maintain a temperature between 32 and 122° F (0 to 50° C) and must have adequate air circulation to ensure proper cooling.

(7)

Page 3

??Enclosed racks must have adequate ventilation. An enclosed rack should not be overcrowded and should have louvers and a fan.

??Make sure that the unit’s ventilation ports are not blocked. If the chassis is installed using slide rails, check for blocked ventilation ports when it is fully in position.

??If the unit is installed in an enclosed rack with a ventilation fan at the top, make sure that heated air drawn upward is not too hot for adequate cooling.

??Baffles can help to 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 are found by experimenting with different arrangements.

Caution: If the unit is placed on a desktop, the rubber feet must remain in place to provide space for cooling air circulation. Inadequate ventilation can result in overheating and damage.

2.4 Access to the Chassis

Space must be provided at the front and rear of the chassis for cable connections. Consider also the possible need to access the chassis for future upgrades, maintenance, and troubleshooting.

2.5 Power Source

The MAX 4’s AC power supply automatically selects either 100-127 volt or 200-240 volt operation.

The Net2Phone MAX 4 requires a ”clean” power source for proper functionality. If you suspect that your AC power is not clean (i.e. if lights occasionally flicker or there are machines with large electric motors in the vicinity), have a qualified technician test the power. Under some circumstances it may be necessary to install a power conditioner.

Warning: Make sure you have read these installation instructions and understand them completely before you connect the system to its power source.

Warning: Before working on a chassis or working near power supplies, unplug the power cord.

Warning: This product relies on the building's installation for short -circuit (over-current) 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).

Caution: To avoid damage from lightning and power surges, install proper grounding.

2.6 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). Following are the distance limitation specifications for Ethernet, serial, and analog telephone interfaces.

(8)

Page 4 2.6.1 Ethernet Maximum Distance

The maximum segment distance for Ethernet 10BaseT is 330 feet (100 meters) (specified in IEEE 802.3).

2.6.2 Serial Port Maximum Distances

Table 4 shows the standard relationship between baud rate and maximum distance for EIA/TIA-232 signals.

EIA/TIA-232 Speed and Distance Limitati ons

Data Rate (Baud) Distance (Feet) Distance (Meters)

2400 200 60

4800 100 30

9600 50 15

19200 25 8

38400 12 4

Caution: EIA/TIA-232 is often used at greater distances than specified above. If you understand the electrical problems that can arise and can compensate for them, you might still be able to get satisfactory results. However, Net2Phone recommends that you keep your cable runs within the standard distance as defined above.

2.7 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.

2.8 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 transmi tters, can destroy the EIA/TIA-232 drivers and receivers in the MAX 4.

If you use twisted -pair cables with a good distribution of grounding conductors in your plant cabling, the likeliness of emitted radio interference is minimized.

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

(9)

Page 5

electromagnetic pulses 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.

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 (EMI).

For advice on the prevention of electromagnetic interference, consult experts in radio-frequency interference (RFI).

3 Installing the MAX 4

The MAX 4 can be installed as a desktop unit.

3.1 Safety Recommendations

Follow these guidelines when working on the system:

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.

Warning: Before working on a chassis or working near power supplies, unplug the power cord on AC units.

Warning: Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or can weld the metal object to the terminals.

Warning: This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.

?? 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.

?? Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

Disassembly:

Do not attempt to disassemble the Net2Phone MAX 4. There are no user-serviceable parts inside the unit.

3.2 Considerations for System Installation

??When installing equipment, connect the ground line first; and when moving the equipment, disconnect the ground line last.

??When installing equipment, always wear an anti-electricity wrist strip.

(11)

Page 7

??The power cable to be used should be provided by the equipment supplier or must be a certified product.

??The environment in which the equipment is operated should be well ventilated and maintained within a temperature range of 0°C ~ 50°C.

??Verify that the power quality is appropriate. (Note whether an electrical light is flickering or a large PC monitor is located nearby.)

??Always connect/disconnect cables after the power switch is turned off.

??The ventilation holes located on both sides of the system should not be blocked by walls or other obstacles.

3.3 Stand -alone (desktop) Installation

1. Locate the equipment on a flat surface.

2. Do not place objects in excess of 20 pounds on top of the equipment .

3. Verify that all four of the rubber feet, needed for proper cooling, are present.

4. Connect a ground line with the ground screw of the equipment. (Ground line specifications:

AWG 18, GREEN/YELLOW.)

5. Connect the system power cable to a grounded (three-conductor) power outlet.

6. Connect the communications cabling as per the illustrations in your User Guide.
