  • Page 17 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.) •...
  • Page 18 General Site Requirements For safety, periodically check the resistance value of the antistatic strap, which Caution 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.
  • Page 19 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.

  • Page 21: Isdn Connections

    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.
  • Page 22 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.
  • Page 23 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.

  • Page 24: Signaling Standards

    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 Distance Distance (Baud) (Feet) (Meters) 38400 56000 The EIA/TIA-449 and V.35 interfaces support data rates up to 2.048 Mbps.

  • Page 26 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.
  • Page 27 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.
  • Page 28 Preparing to Connect to a Network Figure 2-4 V.35 Serial Transition Cable Connectors, Network End 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.
  • Page 29 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.
