If you remove a chassis during installation and maintenance, place the chassis cover in a safe place.

•

Keep tools away from walk areas to prevent hazards such as slips, trips, and falls.

•

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

•

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

•

Warning

Safety Tips

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

Use these tips as safety guidelines when installing and working around this equipment:

Locate the emergency power off switch for the room in which you are working in order to be able to

•

quickly turn off power, if an electrical accident occurs.

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.

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, and then take

◦

appropriate action.

Preventing Electrostatic Discharge Damage

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

Ensure that the chassis is electrically connected to earth ground.

•

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

•

Connect a clip to the ESD-strap connection jack (to the left of the power switch on the rear of the chassis)

•

or to an unpainted chassis frame surface.

Planning Your Installation

Temperature Control and Ventilation

Caution

For safety, periodically check the resistance value of the antistatic strap, which should be between 1 МΩ and 10 МΩ.

Temperature Control and Ventilation

The installation location (room, closet, or cabinet) for Cisco VG310 and Cisco VG320 should always be well ventilated and provide adequate air circulation to ensure proper cooling. The room temperature should be between 32 °F and 104 °F (0 °C to 40 °C).

The Cisco VG310 and Cisco VG320 analog voice gateway chassis is designed for back-to-front airflow.Note

Enclosed Racks

Note

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

If the Cisco VG310 or Cisco VG320 analog 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 unit are not blocked.

Note

Baffles can help isolate exhaust air from intake air. Baffles also help draw cooling air through the cabinet. The best location for baffles depends on the airflow patterns in the rack. You can test the airflow by experimenting with different equipment arrangements.

Wall-Mounted

If Cisco VG310 or Cisco VG320 is installed on a wall, there should be plenty of space on both sides to ensure that there is adequate airflow 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.

OL-31292-01 15

Cisco VG310 and Cisco VG320 Voice Gateways Hardware Installation Guide

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.

Rack Requirements

Use the following information to plan your equipment-rack configuration:

Allow clearance around the rack for maintenance.

•

Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each voice

•

gateway 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 it.

When mounting a chassis in an open rack, ensure that the rack frame does not block the ports. If the

•

chassis is installed on slides, check the position of the chassis when it is seated in the rack.

Planning Your Installation

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 Installing the Ground Connection, on page 33.

Power Source

You can connect Cisco VG310 or Cisco VG320 to either an AC power source or a +12V DC power supply.

Caution

The 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 must reboot it with only a single power source.

For more information, see Connecting Power, on page 36.

Cable Types

The cable types are dependent on the Cisco VG310 or Cisco VG320 analog voice gateway that you are using. For more information, see Interfaces and Service Capabilities of Cisco VG310 and Cisco VG320 , on page

3 and Cable Specifications and Information, on page 69.

Planning Your Installation

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 Voice Gateway ports:

• Gigabit Ethernet ports—The maximum segment distance for Gigabit Ethernet is 330 feet (100 meters)

(specified in IEEE 802.3).

• FXS analog voice ports—The maximum distance is established by a total allowable loop resistance,

including the phone or terminal equipment, of 600 Ohms.

Console Port and Auxiliary Port Considerations

Cisco VG310 and Cisco VG320 include an asynchronous serial console port and an auxiliary port. The console and auxiliary ports provide access to the unit either locally using a console terminal connected to the console port, or remotely, using a modem connected to the auxiliary port. This section discusses important cabling information to consider before connecting the unit to a console terminal or modem.

The main difference between the console and auxiliary ports is that the auxiliary port supports hardware flow control and the console port does not. Flow control paces the transmission of data between a sending device and a receiving device. Flow control ensures that the receiving device can absorb the data sent to it before the sending device sends more. When the buffers on the receiving device are full, a message is sent to the sending device to suspend transmission until the data in the buffers has been processed. Because the auxiliary port supports flow control, it is ideally suited for use with the high-speed transmissions of a modem. Console terminals send data at speeds slower than modems do; therefore, the console port is ideally suited for use with console terminals.

Console Port Connections

Cisco VG310 and Cisco VG320 have EIA/TIA-232 asynchronous (RJ-45) and USB 5-pin mini Type B,

2.0-compliant serial console ports. The console port do not have any hardware flow control. Shielded USB cables with properly terminated shields are recommended.

EIA/TIA-232

Depending on the cable and the adapter used, this port appears as a Date Terminal Equipment (DTE) or Data Circuit-Terminating Equipment (DCE) device at the end of the cable. Only one port can be used at the same time.

The default parameters for the console port are 9600 baud, 8 data bits, 1 stop bit, and no parity. The console port does not support hardware flow control.

USB Serial Console

Use the USB console port on the chassis to access the Cisco IOS CLI and perform configuration tasks. A terminal emulation program, such as Microsoft HyperTerminal for Windows, is required to establish communication between the voice gateway and a PC. The USB serial console port connects directly to the USB connector of a PC using a 5-pin mini USB Type A or USB Type-B cable. The USB console supports full-speed (12 Mbps) operation.

OL-31292-01 17

Cisco VG310 and Cisco VG320 Voice Gateways Hardware Installation Guide

Auxiliary Port Connections

Always use shielded USB cables with a properly terminated shield.Note

The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 1 stop bit. The USB console port does not support hardware flow control.

For operation with Microsoft Windows, the Cisco USB Console Driver must be installed on the PC connected to the console port. If the driver is not installed, a series of prompts guide you through a simple installation process.

Planning Your Installation

Note

You may encounter USB driver-related errors if you are using a PC with Microsoft Windows 7.0, 64-bit operating system to establish connectivity with a voice gateway. As a workaround, you can install the Cisco USB console driver from:

The Cisco USB Console Driver allows plugging and unplugging of the USB cable from the console port without affecting Microsoft HyperTerminal operations. No special drivers are needed for Mac OS X or Linux.

Only one console port can be active at a time. When a cable is plugged into the USB console port, the RJ-45 port becomes inactive. Conversely, when the USB cable is removed from the USB port, the RJ-45 port becomes active.

Baud rates for the USB console port are 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps.

4-pin mini USB Type-B connectors are easily confused with 5-pin mini USB Type-B connectors. Only the 5-pin mini USB Type-B is supported.

Planning Your Installation

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 the following implications on 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 Cisco VG310 or Cisco VG320.

Consider the following guidelines:

To prevent emitted radio interference, use twisted-pair cables with a good distribution of grounding

•

conductors in your plant cabling.

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. Take precautions to avoid these problems by providing a properly grounded and shielded environment and by installing electrical surge suppression.

Interference Considerations

• All module openings must be either occupied or covered to prevent electromagnetic interference—you

must either install a module in its vacant slot or install a cover plate over the opening.

Consult experts in radio-frequency interference (RFI) for advice on the prevention of electromagnetic

•

interference.

Note

To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of: 40 °C (104 °F). Statement 1047

If installed on enclosed racks, the racks must have adequate ventilation. An enclosed rack should never be overcrowded and should have louvers and a fan.

If the Cisco VG310 or Cisco VG320 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 pass through the Cisco VG310 or Cisco VG320 chassis.

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 chassis are not blocked.

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.

Machine screws for securing the chassis in a rack are not included in the package. You must arrange for machine screws of the appropriate size required by your rack.

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 to, or not shielded from, the off-premise wiring or power cables during a lightning strike or power surge, the on-premise wiring can carry a dangerous discharge to the attached interface, equipment, and nearby personnel.

Installing the Cisco VG310 and Cisco VG320 Voice Gateways

Connecting the Chassis to an AC Power Source

Warning

Caution

The Cisco 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 must reboot it with only a single power source.

Depending on the power source you want to connect, see:

Connecting the Chassis to an AC Power Source, on page 37

•

Connecting the Chassis to a +12V DC Power Supply, on page 38

•

Connecting the Chassis to an AC Power Source

Before You Begin

Caution

Note

AC connected units must have a permanent ground connection in addition to the power cable ground wire.Warning

Design your installation to use either AC or DC power source. Do not use AC and DC power at the same time. If you do, the unit stops operating, and you must 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.

The Cisco VG310 or Cisco VG320 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.

Follow these guidelines before you connect the chassis to an AC power source:

While being connected to an AC power source, do not connect the chassis to the DC power supply as

•

an arrangement for backup power in the event of AC power failures.

To ensure uninterrupted power, connect the chassis to an uninterruptible power supply (UPS). For more

•

information on connecting a UPS to the chassis, see Connecting a UPS to an AC-Powered Voice Gateway,

Cisco VG310 and Cisco VG320 Voice Gateways Hardware Installation Guide

38 OL-31292-01

Installing the Cisco VG310 and Cisco VG320 Voice Gateways

When you make the settings for the DC source voltage, you must consider the voltage drops between

•

the DC power supply and the DC input connector on Cisco VG310 or Cisco VG320. To ensure optimal performance, the input voltage at the DC input connector should not be less than 11.5 V.

Use a battery of higher capacity if you require longer periods of battery operation (for example, up to 8

•

hours).

If you use a battery of high capacity or a high-capacity DC source to power the chassis, install an external

•

fuse for protection against fault and fire.

Power Connector for the DC Power Supply

The Cisco VG310 and Cisco VG320 analog voice gateways support the Molex Mini-Fit Jr. 5557 Series, 8-circuit dual-row, +12V DC power connector (Molex P/N 39-01-2085). The +12V DC power input is designed to be used with an external UPS system, and it has status signals that are reported to Cisco VG310 or Cisco VG320.

The following table shows the connector pin assignment for the +12V DC power connector pin assignment.

Identifying a Rollover Cable

You can identify a rollover cable by holding the plugs side by side, with the tab at the back, and comparing the modular plugs at the two ends of the cable. The wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. (Figure 20.)

If your cable is from Cisco Systems, pin 1 is white on one plug, and pin 8 is white on the opposite plug.

Figure 20: Identifying a Rollover Cable

Cable Specifications and Information

Pin 1 and pin 8 are of the same color.Note

Note

A rollover cable reverses the wire connections at the opposite ends: 1 to 8, 2 to 7, 3 to 6, 4 to 5, 5 to 4, 6 to 3, 7 to 2, and 8 to 1.

Cable Specifications and Information

Serial Connection Signals and Pinouts

This section provides information about the 1-port serial WAN interface card (WIC). With the appropriate serial transition cable, this WIC can provide an EIA/TIA-232, EIA/TIA-449, V.35, X.21, DTE/DCE, EIA-530 DTE, or NRZ/NRZI serial interface.

Types of Serial Cables

Five types of serial cables (also called serial adapter cables or serial transition cables) are available from Cisco Systems:

EIA/TIA-232 Connections, on page 79

•

EIA/TIA-449 Connections, on page 80

•

V.35 Connections, on page 80

•

X.21 Connections, on page 81

•

EIA/TIA-530 Connections, on page 81

•

Serial Connection Signals and Pinouts

All serial cables provide a universal plug at the WIC end. The network end of each cable provides the physical connectors most commonly used for the interface. For example, the network end of the EIA/TIA-232 serial cable is a DB-25 connector, the most widely used EIA/TIA-232 connector.

All serial interface types except EIA-530 are available in DTE or DCE format: DTE with a plug connector (male) at the network end and DCE with a receptacle (female) at the network end. V.35 is available in either mode with either gender at the network end. EIA-530 is available in DTE only.

Connecting the WIC to the Network

The serial WIC uses a universal high-density, 60-pin receptacle. Each universal port requires a serial port adapter cable that determines the port’s electrical interface type and mode: DTE or DCE. Although all port adapter cables use a universal plug at the serial module end, the network end of each cable type uses the physical connectors commonly used for the interface. For example, the network end of the EIA/TIA-232 port adapter cable is a DB-25 connector, the most widely used EIA/TIA-232 connector.

After you install the serial WIC, use the appropriate serial cable to connect the WIC DB-60 serial port to one of the following types of equipment:

An asynchronous modem if connecting to an analog telephone line.

•

A synchronous modem data service unit/channel service unit (DSU/CSU), or other data circuit-terminating

•

equipment (DCE), if connecting to a digital WAN line.

EIA/TIA-232 Connections

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

For connection to a Cisco VG310 or Cisco VG320 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 on the other (Figure 24). The DB-25

connector can be male for DTE or female for DCE. To order a cable, see Obtaining Technical Assistance,

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 VG310 or a Cisco VG320 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 on the other (Figure

25). The DB-37 connector can be male for DTE or female for DCE. To order a cable, see Obtaining Technical

Assistance, on page xi.

V.35 Connections

The V.35 standard is recommended for speeds up to 48 kbps, although in practice, it is used successfully at 4 Mbps. Cisco VG310 and Cisco VG320 support speeds up to 2.048 Mbps.

Use the V.35 serial transition cable (not included with... ) the Cisco 12-in-1 connector on one end and a standard 34-pin Winchester-type connector (as shown in Figure 26) on the other. The 34-pin Winchester-type

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 on the other (Figure 27). The DB-15 connector can be male for DTE or female for DCE. To order a cable, see Obtaining Technical Assistance, on page xi.

EIA/TIA-530 Connections

The EIA/TIA-530 standard, which supports balanced transmission, provides 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. The Cisco VG310 and Cisco VG320 Analog Voice Gateways support speeds up to 2.048 Mbps.

USB Type A-to-USB 5-Pin Mini Type B Cable

The USB console port uses a USB Type A to 5-pin mini Type B cable. The USB Type A-to-USB mini Type B cable is not supplied. You can order an accessory kit that contains this cable. To order a cable, see Obtaining

Technical Assistance, on page xi.

The RJ-45 console port uses an eight-pin RJ-45 connector (Table 25 and Table 26). The supplied RJ-45-to-DB-9 adapter cable is used to connect the console port of Cisco VG310 or Cisco VG320 to a console PC. Provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console port to a terminal.
