About Mounting Location Requirements
CHAP T ER
2
You can mount a Cisco VG202, Cisco VG202XM, Cisco VG204, or Cisco VG204XM voice gateway
chassis onto either a wall or on a desk or shelf.
The mounting location must provide the following:
• Adequate access to the chassis. See Access to the Chassis, page 2-1.
• Access to a suitable power source. See Power Source, page 2-2.
• Allowance for adequate heat dissipation and airflow around the chassis. Inadequate ventilation can
result in overheating and damage. See Temperature Control and Ventilation, page 2-2.
• Access to an appropriate earth ground. See Installing the Ground Connection, page 3-7.
Access to the 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.
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1001
Read the installation instructions before you connect the system to its power source.
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)
1005
The device is designed for connection to TN and IT power systems.
Temperature Control and Ventilation
• Temperature Control, page 2-2
• Ventilation for Wall Mounting, page 2-2
• Ventilation for Desktop Mounting, page 2-2
Statement 1004
Statement
Statement 1007
Temperature Control
The installation area (room, closet, or cabinet) for the voice gateway chassis must be well ventilated and
provide adequate air circulation to ensure proper cooling. The room temperature should be maintained
between 32 to 122 degrees F (0 to 50 degrees C).
Ventilation for Wall Mounting
If you install the chassis onto a wall, ensure that there is plenty of space on all sides of the chassis to
allow adequate airflow through the chassis.
Ventilation for Desktop Mounting
If you place the chassis on a desk or shelf, do not stack other equipment or paper on top of it. Provide
plenty of space for air circulation on all four sides of the chassis.
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).
• FXS Analog Voice Port Maximum Distance, page 2-3
• Interference Considerations, page 2-3
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 Ohm.
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:
Distance Limitations for Interface Cables
• Unshielded plant cabling can emit radio interference.
• Strong electromagnetic interference (EMI), especially caused by lightning or radio transmitters, can
destroy the EIA/TIA-232 drivers and receivers in the Cisco VG202, Cisco VG202XM,
Cisco VG204, or Cisco VG204XM voice gateways.
If you use twisted-pair cables with a good distribution of grounding conductors in your plant cabling,
emitted radio interference is unlikely.
If your cables exceed the recommended distances, or if your cables pass between buildings, you must
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 of EMI without
using 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. To prevent electromagnetic interference, all module openings must be either occupied or
covered.
For advice on the prevention of electromagnetic interference, consult experts in radio-frequency
interference (RFI).
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.
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.
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.
Statement 1043
• 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; 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.
3-2
• 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.
CautionFor safety, periodically check the resistance value of the antistatic strap, which should be between 1 and
10 megohm (Mohm).

Mounting the Chassis onto a Wall
Warning
This unit is intended to be mounted on a wall. Please read the wall-mounting instructions carefully
before beginning installation. Failure to use the correct hardware or to follow the correct procedures
could result in a hazardous situation to people and damage to the system.
Statement 248
You can mount the chassis onto a wall or other vertical surface by using the molded mounting-screw slots
on the bottom of the chassis and two number-six, 3/4 inch (M3.5 x 20 mm) screws. You must provide
the screws. Figure 3-2 shows the mounting-screw slots.
Figure 3-2Mounting-Screw Slots for Mounting a Cisco VG202, Cisco VG202XM, Cisco VG204, or
Cisco VG204XM Voice Gateway Chassis onto a Wall
1Rubber feet 2Mounting-screw slots
Before You Begin
Ensure that you meet the following conditions when you mount the chassis onto a wall:
• The LEDs on the front panel face upward and are easily visible, because you will use the LEDs as
status and problem indicators.
• The back panel faces downward, to reduce strain on the cable connections.
• The power supply rests on a horizontal surface such as the floor or a table. If the power supply is
not supported, it can place strain on the power supply cable and cause it to disconnect from the
connector on the back panel of the chassis.
Step 1Secure two screws 5 7/16 in (13.81 cm) apart into a wall and 5/32 in (0.40 cm) out from the wall.
Step 2Hang the chassis on the screws as shown in Figure 3-3.

Step 3Place the power supply on a horizontal surface.
CautionIf you are mounting the voice gateway on drywall, use hollow-wall anchors (1/8 inch with 5/16-inch drill
bit, or M3 with 8-mm drill bit) to secure the screws. If the screws are not properly anchored, the strain
of the network cable connections could pull the voice gateway from the wall. Use two wall anchors with
washers. Wall anchors and washers must be size number 10.

power supply
Setting the Chassis on a Desktop
You can place the voice gateway chassis on a desktop or shelf.
CautionDo not place anything on top of the chassis that weighs more than 10 lb (4.5 kg). Excessive weight on
top can damage the chassis.
Procedure
Step 1Place the four rubber feet (from the accessory kit) in the four indentations on the underside of the chassis.
This helps provide proper airflow through and around the chassis.
Step 2Place the chassis onto a smooth, flat surface.
Installing the Ground Connection
You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance
with local electrical safety standards.
• 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
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection
Warning
authority or an electrician if you are uncertain that suitable grounding is available.
Use copper conductors only.
Statement 1025
Statement 1024
Before You Begin
Locate a suitable ground.
TipUsing a multimeter, measure the resistance between various possible ground locations, such as 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 chassis and the ground of a power tap, and between the chassis
and the ground of a junction box. A good ground connection should read between 0.0 and 0.5 Ohm.
Procedure
Step 1Strip one end of the ground wire to the length required for the ring terminal.
Step 2Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size. (See
Figure 3-4.)
Figure 3-4Crimping a Ground Lug onto the Ground Wire
Step 3
Attach the ring terminal to the chassis as shown in Figure 3-5. For a ring terminal, use one of the screws
provided. Use a number 2 Phillips screwdriver to tighten the screws to a torque of 8 to 10 in-lb (0.9 to
1.1 N-m).
Step 4Connect the other end of the ground wire to a grounding point at your site.

Statement 1001
Take care when connecting units to the supply circuit so that wiring is not overloaded.
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 (240 VAC, 10A international)
Statement 1005
Statement 1018
OL-15959-01
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.
