External Connections and Chassis Cable Ports

When connecting the router internal ports to external cables or exterior devices, you must thread the
router cables through the chassis cable ports designated for this purpose. Some chassis ports are reserved
for specific cables and remaining ports can be used based on your network configuration and cabling
requirements.

There are nine cable ports on the chassis base and two ports on the chassis door (Figure 6-8). Some ports
are reserved for a specific cables types, as indicated Figure 6-8.

Caution When you make router cable connections through these ports, you must use cable glands as described in

Using Cable Glands, page 6-11, to protect the router interior from environmental elements, including

moisture, heat, cold, and dust. Failure to use cable glands with the chassis cable ports can result in
damage to the router.

Cable Requirements

Cables used with the cable glands should meet the following criteria:

• Outdoor-rated

• UV-stabilized

• Plenum-rated

• Minimum 1/2 in. (12.7 mm) in diameter

Caution Cables must be a minimum of 1/2 in. in diameter to create an adequate seal within the cable glands.

Using smaller cables could result in an inadequate seal and therefore expose the router interior to
environmental elements.

Cable Glands Installation Steps

Follow these steps for every cable that you will connect through the chassis cable ports on the router.

Step 4 and Step 5 can be done ahead of time and the prepared cable gland assembly can be transported

to the router installation site.
The cable glands components referred to in this section are shown in Figure 6-10.

Additional Router Connections

Note Figure 6-12 shows an Ethernet cable but the steps are the same for all cable types.

Step 1 Verify the cable you are using meets the requirements described in Cable Requirements, page 6-13.
Step 2 Remove the liquid tight-seal from the port on the router. Use the 13-mm wrench if needed.

The router is shipped with liquid tight seals in unused ports. Figure 6-8 illustrates a liquid tight seal.

Step 3 Use your hands to attach the cable glands adapter (item 1 in Figure 6-10) into the chassis cable port on

the router (Figure 6-11).

Step 4 Thread the following cable glands components over the cable in this order (Figure 6-12):

1. Cap

2. Split gasket

3. Grommet

Step 5 Slide the split gasket along the cable and into the grommet, pressing firmly to ensure the gasket is

completely seated in the grommet.

Step 6 Thread the connector-end of the cable through the router port and insert it into the corresponding router

connector.

Step 7 Slide the cap along the cable, over the grommet, and then over the router port. Hand-tighten, then use

the 13-mm wrench to tighten to 6-7 foot-pounds of torque.

antennas (one main antenna and one diversity antenna). Diversity antennas improve the quality and
reliability of the wireless connection. Because they are placed in different locations on the router, main
and diversity antennas detect different amounts of interference. The router uses the antenna with the
least interference to obtain the best signal.

The total number of antennas installed on the router depends on:

• Number of modules installed in the router.

• Module types that are installed in the router

This section describes the antenna ports, and includes the following topics:

• Unused Antenna Ports, page 8-5

• Antenna Port Numbering, page 8-5

Unused Antenna Ports

Liquid-tight, female N-connectors are installed in any unused antenna ports. The N-connector protects
the router interior from environmental elements including water, heat, cold, and dust. The N-connectors
are installed in unused antenna ports before the router is shipped.

When you install or replace an antenna in a port with an N-connector:

• Chassis-mounted antennas—Remove the N-connector before installing a chassis-mounted antenna.

• External antennas—Connect the supported Cisco lightning arrestor to the N-connector, then connect

the antenna cable to the lightning arrestor.

Safety Warnings

Before performing any of the tasks in this chapter, read the safety warnings in the Installation Safety and

Site Preparation chapter.

Preventing Electrostatic Discharge Damage

SD flash memory modules are sensitive to electrostatic discharge (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 or ankle strap and ensure that it makes good skin contact.

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

• Place a removed the 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 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.

Chapter 9 Using the SD Flash Memory Module

Tools You Supply

You must provide a 13-mm box-end wrench or socket set to access the SD card.

Removing and Inserting the SD Card

To install or remove and SD card:

Step 1 Use the wrench to loosen the seal that covers the SD card slot (Figure 9-2).
Step 2 Confirm that the SD card LED (Figure 9-3) displays one of the following states:

• Green—Installed SD card is operating normally.

• Amber blinking—An unsupported card is installed in the router SD card slot.

• Amber flashing—No SD card is installed in the router SD card slot.

Caution Do not replace the SD card if the LED is blinking green. A blinking green state indicates that a data

transfer between the router and the SD card is in progress. Removing the card during a data transfer will
interrupt this process and could damage system data.

Step 3 To remove an SD card from the router:

a. Press the SD card in slightly. The card moves outward so that it projects from the slot.

DEC. 2011—EFT REVIEW DRAFT—CISCO CONFIDENTIAL

Online Installation and Removal

A non-Cisco module can be installed or removed while the router is installed (usually on a pole top) and
operating normally.

Reviewers: Please confirm the above statement.

Certification

A non-Cisco module that is installed on the router does not interact with the router chassis. Connecting
a non-Cisco module to the router does not certify the module. Before installing the module, verify that
it is certified for use in your environment.

Power

The router interior features a 4-pin, Micro-Fit 3.0 connector, which provides 12 volts of power to a
connected module. See

Figure 11-5 for an illustration of the power connector.

1. A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF or 1000BASE-LX/LH SFP modules
and a short link distance can cause transceiver saturation and an elevated bit error rate (BER). When using the LX/LH SFP
module with 62.5-micron diameter MMF, you must also install a mode-conditioning patch cord between the SFP module and
the MMF cable on both the sending and receiving ends of the link. The mode-conditioning patch cord is required for link
distances greater than 984 feet (300 m).

2. 1000BASE-ZX SFP modules can send data up to 62 miles (100 km) by using dispersion-shifted SMF or low-attenuation SMF;
the distance depends on the fiber quality, the number of splices, and the connectors.

Starting a Router Terminal Session

This appendix describes how to start a terminal session with the Cisco 1240 Connected Grid Router
using the console port. Start a terminal session with the router when you are at the router installation
location and want to administer the router with a direct connection using the command-line interface
(CLI) software.

Before You Begin

Before you start a terminal session with the router, you must connect a PC or PC terminal to the router
console port following the instructions in

Installing the Router.

About the Console Port

APPENDIX

Connecting the Console Port, page 6-15 in the chapter

B

Caution The console port does not support cable glands. When a cable is connected to this port, the router interior

is exposed to environmental elements, which can damage the port and the router interior. This port
should be exposed only during terminal sessions, when a cable is connected to the port. This port should
never be left unattended when in use.

The console port is an asynchronous serial port that allows you to connect to the device for initial
configuration through a standard RS-232 port with an RJ-45 connector. Any device connected to this
port must be capable of asynchronous transmission.

Console Port Settings

Configure the following parameters for the console port:

Parameter Console Port Setting Description

Baud 9600 Specifies the transmission speed for the connection.
Data bits 8 Specifies the number of bits in an 8-bit byte that is used for data.

DEC. 2011—EFT REVIEW DRAFT—CISCO CONFIDENTIAL

Parameter Console Port Setting Description

Parity None Specifies the odd or even parity for error detection.
Stop bits 1 Specifies the stop bits for an asynchronous line.

Using the Ctrl-C Command

The router console port is located on the router exterior and is accessible by removing the seal over the
console port. (For details, see

On many Cisco routers, you can enter Ctrl-C to interrupt the router startup process and then delete or
change the admin password, or view or delete the router configuration.

To prevent unauthorized access to the router configurations and passwords, the Ctrl-C command is
disabled on the Cisco

CGR 1240 Router while it is booting up and loading the system software.

Console Port, page 2-15 in the chapter Router Hardware Description.)

Connecting to the Console Port with Microsoft Windows

This section describes how to connect to the router console port using Microsoft Windows.

Step 1 Start a terminal emulator application, such as Windows HyperTerminal (included with some versions of

Windows

Step 2 Configure the terminal emulation software with the parameters described in About the Console Port,

page B-1.

Step 3 Connect to the router.

OS) or PuTTY.

Connecting to the Console Port with Mac OS X

This procedure describes how to connect a Mac OS X system USB port to the console using the built-in
OS

X Terminal utility.
