Follow these guidelines when working on equipment powered by electricity:
- Locate the emergency power-off switch in the room in which you are working. If an electrical accident occurs, you can quickly turn off the power.
- Disconnect all power before doing the following:
– Installing or removing a chassis
- Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.
- Do not work alone if hazardous conditions exist.
- Never assume that power is disconnected from a circuit. Always check.
- Never open the enclosure of the internal power supply.
- If an electrical accident occurs to another person, proceed as follows:
– Use caution; do not become a victim yourself.
– Turn off power to the device.
– 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.
In addition, use the following guidelines when working with any equipment that is disconnected from a power source but has telephone wiring or other network cabling connections:
- Never install telephone wiring during a lightning storm.
- Never install telephone jacks in wet locations unless the jack is specifically designed for it.
- Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at the network interface.
- Use caution when installing or modifying telephone lines.
- Remove power cables from all installed power supplies before opening the chassis.
Prevent Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It can occur if electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. Always follow these ESD prevention procedures when removing and replacing modules:
- Ensure that the router chassis is electrically connected to the ground.
- Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
- If no wrist strap is available, ground yourself by touching a metal part of the chassis.
For the safety of your equipment, periodically check the resistance value of the anti-static strap. It should be between 1 and 10 megohms (Mohm).
General Site Requirements
This section describes the requirements your site must meet for the safe installation and operation of your router. Ensure that the site is properly prepared before beginning installation. If you are experiencing shutdowns or unusually high errors with your existing equipment, the guidelines provided in this section can also help you isolate the cause of failures and prevent future problems.
General Precautions
Observe the following general precautions when using and working with your Cisco 4000 Series ISRs.
- Keep your system components away from radiators and heat sources, and do not block cooling vents.
- Do not spill food or liquids on your system components, and never operate the product in a wet environment.
- Do not push any objects into the openings of your system components. Doing that can cause fire or electric shock by shorting out interior components.
- Position system cables and power supply cables carefully. Route system cables and the power supply cable and plug so that they cannot be stepped on or tripped over. Be sure that nothing else rests on your system component cables or power cable.
- Do not modify power cables or plugs. Consult a licensed electrician or your power company for electrical modifications at your site. Always follow your local and national wiring rules.
- If you turn off your system, wait at least 30 seconds before turning it on again to avoid system component damage.
Site Selection Guidelines
Cisco 4000 Series ISRs require specific environmental operating conditions. Temperature, humidity, altitude, and vibration can affect the performance and reliability of the router. The following sections provide specific information to help you plan for the proper operating environment.
Cisco 4000 Series ISRs are designed to meet the industry EMC, safety, and environmental standards described in the Regulatory Compliance and Safety Information for the Cisco 4000 Series ISR s document.
Site Environmental Requirements
Environmental monitoring in the router protects the system and components from damage caused by excessive voltage and temperature conditions. To ensure normal operation and avoid unnecessary maintenance, plan and prepare your site configuration before installation. After installation, make sure the site maintains the environmental characteristics as shown in Table 2-1 .
Physical Characteristics
Be familiar with the physical characteristics of the Cisco 4000 Series ISRs to assist you in placing the system in the proper location.For more information on the physical characteristics of Cisco 4000 Series Integrated Services Routers (ISRs), refer to the Cisco 4000 Series Integrated Services Routers datasheet .
The following list describes additional Cisco 4000 Series ISRs chassis characteristics:
- Cable-management brackets at each Cisco 4000 Series ISRs locations can hold 16 ports of STP/UTP RJ 45 cables
- Cable-management brackets allow a bend radius of 1.5 inches for cables
- Rack-mount brackets that have optional mounting location. It allow you to mount on a front to rear rail variance distance of 15.50/394mm to 19.00/482.6mm
Rack Requirements
Some Cisco routers include brackets for use with a 19-inch rack or, if specified in your order, optional larger brackets for use with a 23-inch rack.
The following information can help you plan your equipment rack configuration:
- Allow clearance around the rack for maintenance.
- Allow at least one rack unit of vertical space between routers.
- Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat generated by equipment at 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 intake or exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated in the rack.
Router Environmental Requirements
Cisco 4000 Series ISRss can be placed on a desktop or installed in a rack. The location of your router and the layout of your equipment rack or wiring room are extremely important considerations for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. Plan for access to both front and rear panels of the router.
When planning your site layout and equipment locations, refer to the “General Site Requirements” section. If you are currently experiencing shutdowns or an unusually high number of errors with your existing equipment, these precautions and recommendations may help you to isolate the cause of failure and prevent future problems.
- Ensure that the room where your router operates has adequate air circulation. Electrical equipment generates heat. Without adequate air circulation, ambient air temperature may not cool equipment to acceptable operating temperatures.
- Always follow the ESD-prevention procedures described in the “Prevent Electrostatic Discharge Damage” section to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.
- Ensure that the chassis cover and module rear panels are secure. All empty network module slots, interface card slots, and power supply bays must have filler panels installed. The chassis is designed to allow cooling air to flow within it, through specially designed cooling slots. A chassis with uncovered openings permits air leaks, which may interrupt and reduce the flow of air across internal components.
- Baffles can help to isolate exhaust air from intake air. Baffles also help to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack. You can find the best placement by experimenting with different configurations.
- When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the equipment individually. Power off other equipment in the rack (and in adjacent racks) to allow the router under test maximum cooling air and clean power.
Power Guidelines and Requirements
Check the power at your site to ensure that you are receiving “clean” power (free of spikes and noise). Install a power conditioner if necessary.
The AC power supply includes the following features:
- Autoselects either 110 V or 220 V operation.
- All units include a 6-foot (1.8-meter) electrical power cord. (A label near the power inlet indicates the correct voltage, frequency [only AC-powered systems], current draw, and power dissipation for the unit.)
Table 2-2 lists power requirements for the Cisco 4000 Series ISRs.

Network Cabling Specifications
The following sections describe the cables required to install your Cisco 4000 Series ISRs:
Console and Auxiliary Port Considerations
The router includes an asynchronous serial console port and an auxiliary port. You access to the router 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 you must consider before connecting the router to a console terminal or modem.
The major 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 and a receiving device. Flow control ensures that the receiving device can absorb the data sent to it before the sending device sends more data. 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 is processed. Because the auxiliary port supports flow control, it is suited for use with the high-speed transmissions of a modem. Console terminals send data at speeds slower than the speeds modems do; therefore, the console port is ideally suited for use with console terminals.
Note Cisco 4221 ISR does not have an auxiliary port.
Console Port Connections
The router has both EIA/TIA-232 asynchronous (RJ-45) and USB 5-pin mini Type B, 2.0 compliant serial console ports. 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 DTE or DCE device at the end of the cable. At a time, only one port can be used.
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. For detailed information about installing a console terminal, see the “Connect to Console Terminal or Modem” section.
For cable and port pinouts, see the Cisco Modular Access Router Cable Specifications document.
T1/E1 Port Pinouts
Figure 2-1 shows the RJ-48C connector used by the T1/E1 ports on the TDM interface module.
Figure 2-2 shows the RJ-48C connector wiring for the T1/E1 cable.
Figure 2-2 RJ-48-to-RJ-48 T1/E1 Cable Wiring

USB Serial Console
The USB serial console port connects directly to the USB connector of a PC using a USB Type A to 5-pin mini USB Type-B cable. The USB Console supports full speed (12Mb/s) operation. The console port does not support hardware flow control.
Note Cisco 4461 supports Mini-USB Type B serial port and Micro-USB Type B serial port
Note Always use shielded USB cables with a properly terminated shield.
The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 1 stop bit. For detailed information about installing a console terminal, see the “Connect to Console Terminal or Modem” section.
For operation with a Microsoft Windows OS version older than Windows 7, the Cisco Windows USB console driver must be installed on a PC connected to the console port. If the driver is not installed, appropriate prompts guide you through a simple installation process. For detailed information about installing the Cisco Windows USB Console Driver, see “Install Cisco Microsoft Windows USB Device Driver” section.
The Cisco Windows USB Console Driver allows plugging and unplugging the USB cable from the console port without affecting Windows HyperTerminal operations. No special drivers are needed for Mac OS X or Linux.
At a time, only one console port can be active. 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.
Note 4-pin mini USB Type-B connectors might be easily confused with 5-pin mini USB Type-B connectors. Only the 5-pin mini USB Type-B is supported.
Auxiliary Port Connections
The router has an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow control. Depending on the cable and the adapter used, this port appears as a DTE or DCE device at the end of the cable.
For connection to a modem, you must use an RJ-45-to-DB-25 adapter cable. This cable is orderable separately along with a DB-9-to-DB-25 adapter.
For detailed information about connecting devices to the auxiliary port, see the “Connect to Console Terminal or Modem” section.
For cable and port pinouts, see the Cisco Modular Access Router Cable Specifications document.
Prepare for Network Connections
When setting up your router, consider distance limitations and potential electromagnetic interference (EMI) as defined by the applicable local and international regulations.
