C H A PT E R 2 Preparing to Install the Router This chapter describes important information to consider before you begin to install the router, and includes the following sections: • • • • Safety Recommendations General Site Requirements Preparing to Connect to a Network Where to Go Next Safety Recommendations Follow these guidelines to ensure general safety: • • • • Keep the chassis area clear and dust-free during and after installation.
Safety Recommendations Warning Ultimate disposal of this product should be handled according to all national laws and regulations. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied your router.) Maintaining Safety with Electricity Follow these guidelines when working on equipment powered by electricity.
Safety Recommendations • • Do not work alone if potentially hazardous conditions exist. Never assume that power is disconnected from a circuit. Always check. Warning Read the installation instructions before you connect the system to its power source. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied your router.
General Site Requirements Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 to 10 megohms (Mohms). General Site Requirements This section describes the requirements your site must meet for safe installation and operation of your system. Ensure that your site is properly prepared before beginning installation. Site Environment The router can be placed on a desktop or mounted in a rack or on a wall.
General Site Requirements • Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to flow effectively within it. An open chassis allows air leaks, which may interrupt and redirect the flow of cooling air from internal components. Configuring Equipment Racks The following information will help you plan an acceptable equipment rack configuration. • Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested because each unit generates heat.
Preparing to Connect to a Network The router power supply includes the following features: • • Autoselects either 110V or 220V operation. All units 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 for the unit.) Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S.
Preparing to Connect to a Network ISDN Connections Use a BRI cable (not included) to connect the router directly to an ISDN. (See Table 2-1.) Warning Network hazardous voltages are present in the BRI cable. If you detach the BRI cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are present on the system card in the area of the BRI port (RJ-45 connector), regardless of when power is turned OFF.
Preparing to Connect to a Network Synchronous Serial Connections Before you connect a device to the synchronous serial port (labeled “SERIAL”), you will need to know the following: • The type of device, DTE or DCE, you are connecting to the synchronous serial interface. • • The type of connector, male or female, required to connect to the device. The signaling standard required by the device. DTE or DCE A device that communicates over a synchronous serial interface is either a DTE or DCE device.
Preparing to Connect to a Network Speed and Distance Limitations Serial signals can travel a limited distance at any given bit rate; generally, the slower the data rate, the greater the distance. All serial signals are subject to distance limits, beyond which a signal degrades significantly or is completely lost. Table 2-3 lists the maximum speeds and distances for EIA/TIA-232 signals. This signaling standard supports unbalanced circuits at signal speeds up to 64 kbps.
Preparing to Connect to a Network Table 2-4 EIA/TIA-449, V.35, X.21, and EIA-530 Speed and Distance Limitations (Continued) Data Rate (Baud) Distance (Feet) Distance (Meters) 38400 256 78 56000 102 31 Caution The EIA/TIA-449 and V.35 interfaces support data rates up to 2.048 Mbps. Exceeding this maximum could result in loss of data and is not recommended. Signaling Standards The synchronous serial port supports the following signaling standards: EIA/TIA-232, EIA/TIA-449, V.35, X.
Preparing to Connect to a Network Figure 2-1 Serial Transition Cables H2485 Router connections EIA/TIA-232 EIA/TIA-449 V.35 X.21 EIA-530 Network connections at the modem or CSU/DSU Although attempting to manufacture your own serial cables is not recommended (because of the small size of the pins on the DB-60 serial connector), cable pinouts are provided in the appendix “Cable Specifications.
Preparing to Connect to a Network EIA/TIA-232 Connections The EIA/TIA-232 standard supports unbalanced circuits at signal speeds up to 64 kbps. The serial port (labeled “SERIAL”) supports synchronous connections. The console and auxiliary ports also use an EIA/TIA-232 connection; however, the console and auxiliary ports support asynchronous connections. The network end of the EIA/TIA-232 serial transition cable (not included) provides a DB-25 connector, as shown in Figure 2-2.
Preparing to Connect to a Network The network end of the EIA/TIA-449 serial transition cable (not included) provides a DB-37 connector, as shown in Figure 2-3. The end that connects to the serial port on the rear panel of the router has a DB-60 connector. EIA/TIA-449 serial transition cables are available with a DB-37 plug or receptacle in either DTE or DCE mode. To order a cable, refer to the section “Obtaining Service and Support” in the “Overview of the Router” chapter.
Preparing to Connect to a Network Figure 2-4 V.35 Serial Transition Cable Connectors, Network End DCE H1616a DTE 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. The network end of the X.
Preparing to Connect to a Network EIA-530 Connections The EIA-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, instead of the 37-pin connector used for EIA/TIA-449. Like EIA-TIA-449, EIA-530 refers to the electrical specifications of EIA/TIA-422 and EIA/TIA-423.
Preparing to Connect to a Network Ethernet model routers include an Ethernet AUI interface, which operates at speeds up to 10 Mbps. The cables and transceivers required to connect the router to an Ethernet network are not included. For ordering information, refer to the section “Obtaining Service and Support” in the “Overview of the Router” chapter. Token Ring Connections The IEEE has established Token Ring as standard 802.5. The distance limitations for the IEEE 802.
Where to Go Next Console Port Connections Your router includes an EIA/TIA-232 asynchronous serial console port (RJ-45). Cables and adapters to connect a console terminal (an ASCII terminal or PC running terminal emulation software) to the console port are included. To connect an ASCII terminal to the console port, use the RJ-45-to-RJ-45 roll-over cable (looks like a telephone cable) with the female RJ-45-to-DB-25 adapter (labeled “TERMINAL”).

A P PEN D I X A Troubleshooting the Router This appendix contains information about how to isolate problems with the router and includes the following sections: • • Isolating Problems Reading the LEDs Isolating Problems The key to problem solving in this system is to try to isolate the problem to a specific subsystem. By comparing what the system is doing to what it should be doing, the task of isolating the problem is greatly simplified.
Isolating Problems Troubleshooting the Power and Cooling Systems Check the following items to help isolate the problem: • When the power switch is in the ON position (|) and the System OK LED is on, are the fans operating? If not, check the fans. • Does the router shutdown after being ON a short time? Check the environmental conditions. The router might be overheating, resulting in a thermal-induced shutdown. Ensure that the chassis intake and exhaust vents are clear.
Reading the LEDs Reading the LEDs The LEDs indicate the current operating condition of the router. You can observe the LEDs, note any fault condition that the router is encountering, and then contact your system administrator or customer service, if necessary. For information about how to contact customer service, refer to the section “Obtaining Service and Support” in the “Overview of the Router” chapter. Figure A-1 to Figure A-7 show the location of the LEDs on the rear panel of the routers.

Upgrading the DRAM SIMM Upgrading the DRAM SIMM This section describes how to upgrade the DRAM SIMM on the system card. You might need to upgrade the DRAM SIMM for the following reasons: • • You upgrade the Cisco IOS feature set or release. Your router maintains large routing tables or other memory-intensive features, such as spoofing or protocol translations. To see how much memory is currently installed in the router, enter the show version command.
Upgrading the DRAM SIMM Step 4 Remove the existing DRAM SIMM by pulling outward on the connectors to unlatch them, as shown in Figure B-6. Be careful not to break the holders on the SIMM connector. Caution To prevent damage, do not press on the center of the SIMMs. Handle each SIMM carefully. Position the new SIMM so that the polarization notch is located at the left end of the SIMM socket. (See Figure B-6.
Replacing the System-Code SIMMs Step 6 Insert the new DRAM SIMM by sliding the end with the metal fingers into the SIMM connector socket at approximately a 45-degree angle to the system card. Gently rock the SIMM back into place until the latch on either side snaps into place. Do not use excessive force because the connector may break. Step 7 Replace the router cover. Follow the instructions in the section “Closing the Chassis” later in this appendix.
Replacing the System-Code SIMMs Note For more information about the copy flash tftp command and other related commands, refer to the Cisco IOS configuration and command reference publications. These publications are available on the documentation CD that came with your router or you can order printed copies. Refer to the section “Ordering Documentation” in the chapter “Overview of the Router” for ordering information.

2 CHAPT E R Preparing to Install the Cisco Multiport Serial Routers This chapter describes the tasks you must perform before you begin to install the Cisco 2500 series multiport serial routers.
Safety Recommendations • Wear safety glasses if you are working under any conditions that might be hazardous to your eyes. • Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. Maintaining Safety with Electricity Follow these guidelines when working on equipment powered by electricity. Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches).
General Site Requirements • Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, 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.
General Site Requirements Warning Ultimate disposal of this product should be handled according to all national laws and regulations. (To see translated versions of this warning, refer to the appendix “Translated Safety Warnings.”) Site Environment The location of individual chassis and the layout of your equipment rack or wiring room are extremely important for proper system operation.
General Site Requirements Configuring Equipment Racks The following tips will help you plan an acceptable equipment rack configuration: • Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. • When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or the exhaust ports.
Prerequisites for System Operation Warning This product relies on the building’s installation for short-circuit (overcurrent) 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). (To see translated versions of this warning, refer to the appendix “Translated Safety Warnings.
Installation Checklist Installation Checklist The Installation Checklist lists the procedures for initial hardware installation of a new multiport serial router. Make a copy of this checklist and mark the entries as you complete each procedure. Include a copy of the checklist for each system in your Site Log. (See the following section, “Creating a Site Log.
Creating a Site Log Creating a Site Log The Site Log provides a record of all actions relevant to the system. Keep it near the chassis where anyone who performs tasks has access to it. Use the Installation Checklist (see the previous section “Installation Checklist”) to verify steps in the installation and maintenance of your system. Site Log entries might include the following: • Installation progress—Make a copy of the Installation Checklist and insert it into the Site Log.
Cabling Considerations Distance Limitations Following are the distance limitation specifications for Ethernet, Token Ring, and serial interfaces. Ethernet Connections The distance limitations for the IEEE 802.3 (10Base5 coaxial cable) specification indicate a maximum segment distance of 1,640 feet (500 m) at a transmission rate of 10 megabits per second (Mbps).
Cabling Considerations Data Rate (Baud) Distance (Feet) Distance (Meters) 38400 50 15 57600 25 7.6 115200 12 3.7 The use of balanced drivers allows EIA/TIA-449 signals to travel greater distances than the EIA/TIA-232 standard. Table 2-2 lists the standard relationship between baud rate and maximum distance for EIA/TIA-449 signals. These limits are also valid for V.35 and X.21.
Console and Auxiliary Port Considerations Console and Auxiliary Port Considerations This section discusses important cabling information that must be considered before you connect the terminals or modems to console and auxiliary ports. The console port and the auxiliary port are used to provide access to the system either locally or remotely. Console Port Connections Each multiport serial router includes an EIA/TIA-232 (RJ-45) console asynchronous serial port.
Network Connection Considerations Network Connection Considerations This sections describes important cabling information that must be considered before making your network connections. The Ethernet or Token Ring ports are used to connect to a LAN; the synchronous serial ports are used to connect to a WAN; and the asynchronous ports are used to provide remote access to the multiport serial routers.
Network Connection Considerations attachment unit (MAU). The Token Ring port labeled UTP uses an RJ-45 Token Ring cable and is connected through an adapter or directly to a MAU. Only one Token Ring port can be used at a time. Synchronous Serial Connections The multiport serial routers offer two high-speed synchronous serial ports and from two to eight (depending on which chassis you have) low-speed asynchronous/synchronous serial interface ports that can be configured as synchronous serial interfaces.
Network Connection Considerations You must use a special serial cable to connect a multiport serial router to a modem or CSU/DSU. This cable is available from Cisco and is usually ordered with the system. The cable uses a DB-60 connector on the chassis end. See the appendix “Cisco Multiport Router Cable Specifications” for cable pinouts. For ordering information, contact a customer service representative.
Inspecting the System Inspecting the System Do not unpack the multiport serial router until you are ready to install it. If the final installation site will not be ready for some time, keep the chassis in its shipping container to prevent accidental damage. When you have determined where you want the multiport serial router installed, proceed with the unpacking.
