General Site Requirements

This section describes the requirements your site must meet for safe installation and operation of your router. Ensure that the site is properly prepared before you begin the installation. If you experience shutdowns or unusually high error rates with your existing equipment, the information in this section can help you isolate the cause of failures and prevent future problems.

Power Supply Considerations

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.

Chapter 2 Preinstallation Requirements

Warning

The device is designed for connection to TN and IT power systems.

The AC power supply includes a 6-foot (1.8-meter) electrical power cord. (A label near the power inlet indicates the correct voltage, frequency [AC-powered systems only], current draw, and power dissipation for the unit.)

Table 2-1 lists power requirements for the Cisco 1800 series fixed-configuration routers.

Ta b l e 2-1 Power Requirements for Cisco 1800 Series Fixed-Configuration Routers

Router Input Power

Without inline power support 100–120V/200–240V, 1.2A/0.6A 90 to 264 VAC

With inline power support 100–120V/200–240V, 1.2A/0.6A 90 to 264 VAC

Site Environment

The Cisco 1800 series fixed-configuration router can be placed on a desktop, installed in a rack, or mounted on a wall or other vertical surface. The location of your router and the layout of your equipment rack or wiring room are extremely important considerations for proper operation. Having 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 the front panel and the back panel of the router. When facing the router front-bezel, airflow is from left to right,

Statement 1007

Input Voltage Tolerance Limits

When you plan your site layout and equipment locations, keep in mind the precautions listed in the “Site

Configuration” section on page 2-5 to help prevent equipment failures and reduce the possibility of

environmentally caused shutdowns. If you are experiencing shutdowns or an unusually high number of errors with your existing equipment, these precautions may help you isolate the cause of the failures and prevent future problems.

Wireless LAN Considerations

The type of antenna used with your wireless router and its location greatly impact the quality of wireless connections to the router. Cisco different antenna types—swivel-mount dipole antennas that mounts on the back panel of the router, a wall-mount antenna, and a ceiling-mount antenna.

• Cisco Multiband Swivel-Mount Dipole Antenna

• Cisco Multiband Diversity Omnidirectional Ceiling-Mount Antenna

• Cisco Multiband Wall-Mount, Corner-Mount, or Mast-Mount Antenna

Site Configuration

The following precautions will help you plan an acceptable operating environment for your router and will help you avoid environmentally caused equipment failures:

• Ensure adequate air circulation in the room where your router operates. Electrical equipment

generates heat. Without adequate air circulation, ambient air temperature may not cool equipment to acceptable operating temperatures.

• To avoid damaging equipment, always follow the ESD-prevention procedures described in the

“Preventing Electrostatic Discharge Damage” section on page 2-3. Damage from static discharge

can cause immediate or intermittent equipment failure.

• Ensure that the chassis cover and module back 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.

Connection Procedures and Precautions

Follow these steps to connect your router to the network:

Step 1 Confirm that the router is powered off. Step 2 Connect each WAN or LAN cable to the appropriate connector on the chassis. For locations of the

chassis WAN and LAN ports, see the

“Chassis Views” section on page 1-7.

• Position the cables carefully, so that they do not put strain on the connectors.

• Bundle the cables so that they do not intertwine.

• Inspect the cables to make sure that the routing and bend radiuses are satisfactory. Reposition

cables, if necessary.

• Install cable ties in accordance with site requirements.

Step 3 Connect the other end of each WAN or LAN cable to the appropriate network device. See Ta b le 4-2 for

information about which network devices to connect each cable to.

Note For cable pinouts, see the Cisco Modular Access Router Cable Specifications document.

Connecting to a Console Terminal or Modem

Your router has asynchronous serial console and auxiliary ports for system management. These ports provide administrative access to your router either locally (with a console terminal or PC) or remotely (with a modem).

Cisco Systems provides the following cables for connecting your router to a console terminal, PC, or modem:

Console and Auxiliary Port Considerations

The router includes an asynchronous serial console port and an auxiliary port. The console and auxiliary ports provide 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 provides important information about cabling that you should consider before you connect the router to a console terminal or a modem.

The main difference between the console port and the auxiliary port 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. Because console terminals send data at slower speeds than modems, the console port is ideally suited for use with console terminals.

Chapter 4 Power, Cable, and Antenna Connection Procedures

Console Port Connections

The router has an EIA/TIA-232 asynchronous serial console port (RJ-45). Depending on the cable and the adapter used, this port will appear as a DTE or DCE device at the end of the cable.

Your router is supplied with an RJ-45-to-DB-9 adapter cable for connecting to a PC that is running terminal emulation software.

To connect the router to an ASCII terminal, use the RJ-45-to-DB-9 cable and a DB-9-to-DB-25 adapter.

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

“Connecting to a Console Terminal or Modem” section on page 4-5.

For cable and port pinouts, see the online document Cisco Modular Access Router Cable Specifications. This document is located on Cisco.com.

Connecting to the Console Port

If a console terminal or PC is connected to the console port, you can configure the router locally. Follow these steps to connect a console terminal or PC that is running HyperTerminal or similar terminal emulation software to the console port on the router:

Connecting to a Console Terminal or Modem

Step 1 Use the blue RJ-45-to-DB-9 console cable to connect the router to a terminal.

Note On the Cisco 1800 series fixed-configuration routers, the console port is color-coded blue.

Step 2 Configure your terminal or terminal emulation software for 9600 baud (default), 8 data bits, 1 stop bit,

and no parity; set flow control to “none.”

Note Because hardware flow control is not supported on the console port, do not connect modems to

the console port. Connect modems only to the auxiliary port.

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.

Your router is supplied with a DB-9-to-DB-25 adapter for connecting to a modem.

For detailed information about connecting devices to the auxiliary port, see the “Connecting to a Console

Terminal or Modem” section on page 4-5.

Connecting the Radio Antennas to the Wireless Router

Connecting to the Auxiliary Port

If a modem is connected to the auxiliary port, a remote user can dial in to the router and configure it. Follow these steps to connect a modem to the auxiliary port on the router:

Step 1 Use the black RJ-45-to-DB-25 modem cable or the RJ-45-to-DB-9 console cable with a DB-9 to DB-25

adapter to connect the router to a modem.

Step 2 Make sure that your modem and the router auxiliary port are configured for the same transmission speed

(up to 115,200 bps is supported) and hardware flow control with data carrier detect (DCD) and data terminal ready (DTR) operations.

Connecting the Radio Antennas to the Wireless Router

If your router has the wireless LAN option, connect the antennas by screwing the antenna connectors in a clockwise direction onto the reverse-polarity threaded Neill-Concelman (RP-TNC) connectors on the back panel of the router. antennas to the router.

inline power supply card. Failure to do so may result in damage to the inline power supply card or to the router.

Caution When installing the inline power supply card, ensure that the card is installed in the proper direction.

Improper installation will result in damage to the inline power supply card. Installation of the inline power supply card requires the installation of three metal standoffs, to which the card is then secured using three screws. Be sure to use all three screws to ensure that the card is installed properly—if the card is not installed in the correct direction, the three screw holes will not match up with the three metal standoffs.

Step 1 Find the metal standoff attachment locations on the system board, which are indicated by a star pattern

surrounding each of the three holes in the system board.

Step 2 Install the three metal standoffs into the system board in the metal standoff attachment locations

(denoted by a star pattern around the holes). Use a 1/4-inch nut driver to tighten the standoffs.

Caution Make sure that the standoffs are straight when installed. Tighten them gently but firmly. The shoulder

of each standoff must be seated tightly against the system board.

Step 3 Place the inline power supply card on top of the three metal standoffs, lining up the metal standoffs with

the screw holes in the inline power supply card.

Step 4 Insert the screws provided in the accessory kit through the inline power supply card and into the metal

standoffs. Carefully tighten the screws with a Phillips screwdriver.

After you install the inline power supply card in the router, install the router cover and connect the inline power supply to the power connector on the back of the router.

Installing the Chassis Cover

The Cisco 1800 series fixed-configuration router has a cover that slides onto the chassis from the back of the chassis. Follow these steps to install the chassis cover on a Cisco router:

Step 1 Gently slide the cover of the router onto the chassis. Step 2 Replace the cover screw that you removed when you opened the chassis. See the “Removing the Chassis

Cover” section on page 7-2.

Removing and Installing CompactFlash Cards

This section describes how to install and replace CompactFlash cards in Cisco 1800 series fixed-configuration routers. It contains the following sections:

• Preventing Electrostatic Discharge Damage

• Removing a CompactFlash Memory Card

• Installing a CompactFlash Memory Card

Preventing Electrostatic Discharge Damage

CompactFlash memory cards are sensitive to electrostatic discharge (ESD) damage. ESD damage, which can occur when electronic cards or components are handled improperly, results in complete or intermittent failures.

To prevent ESD damage, follow these guidelines:

• Always use an ESD wrist strap, and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• Place a removed CompactFlash memory card on an antistatic surface or in a static shielding bag. If

the card will be returned to the factory, immediately place it in a static shielding bag.

• Avoid contact between the card and your clothing. The wrist strap protects the card from ESD

voltages on the body only; ESD voltages on clothing can still cause damage.

• Do not remove the wrist strap until the installation is complete.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be

between 1 and 10 megohms (Mohm).

Removing a CompactFlash Memory Card

To remove a CompactFlash memory card from the chassis, perform the following steps. See Figure 7-5.

Caution Do not remove a CompactFlash memory card from the chassis while it is being accessed. A blinking CF

LED indicates that the CompactFlash memory is being accessed. Removing the CompactFlash memory card from the router while it is being accessed can damage your router.

Step 1 Press the ejector button next to the CompactFlash memory card. The ejector button moves outward so

that it projects from the panel.

Step 2 Press the ejector button again. This ejects the CompactFlash memory card partway out of its slot. Step 3 Pull the CompactFlash memory card out of its slot. Step 4 Push the ejector button in until the button is flush with the bezel.

Caution To prevent damage to the ejector mechanism, the ejector button must remain pressed all the way in (flush

against the bezel) when it is not being used to eject a CompactFlash memory card.

the panel.

Note If the ejector button is projecting beyond the panel, push it in until it is flush with the bezel.

Step 2 Insert the CompactFlash memory card into the slot until it is fully seated. The ejector button remains

flush with the panel.

Note If the ejector button is projecting from the panel after you insert the CompactFlash memory card,

remove the CompactFlash memory card, press the ejector button until it clicks, and reinsert the CompactFlash memory card.

Caution To prevent damage to the ejector mechanism, the ejector button must remain pressed flush against the
