Caution
•
Outdoor-rated
•
UV-stabilized
•
Plenum-rated
•
Minimum 1/2 in. (12.7 mm) in diameter
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.

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

Connecting the SFP Ports
About
Small Form-Factor Pluggable (SFP) modules are devices that plug into the router SFP connectors shown
in Figure 6-16. The transceiver connects the electrical circuitry of the module with the optical or copper
network.
The SFP module used on each port must match the wavelength specifications on the other end of the
cable, and the cable must not exceed the stipulated cable length for reliable communications.
Use only Cisco SFP transceiver modules with the router. Each SFP transceiver module supports the
Cisco Quality Identification (ID) feature which allows a Cisco switch or router to identify and validate
that the transceiver module is certified and tested by Cisco.
Warning
Class 1 laser product. Statement 1008
Caution
Do not remove the dust plugs from the fiber-optic SFP module port or the rubber caps from the
fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module
ports and cables from contamination and ambient light.
Caution
Cisco recommends that you not install or remove the SFP module while the fiber-optic cable is attached
to it because of the potential damage to the cables, to the cable connector, or to the optical interfaces in
the SFP module. Disconnect the cable before you remove or install an SFP module.
Materials and Tools You Supply
You must provide these tools and materials to install the SFP transceiver module:
•
Wrist strap or other personal grounding device to prevent ESD occurrences.
•
Antistatic mat or antistatic foam to set the transceiver on.
•
Fiber-optic end-face cleaning tools and inspection equipment. For complete information on
inspecting and cleaning fiber-optic connections, see the white-paper document at this URL:
http://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml
Connecting
You can connect SFP modules to these ports while the router is operating normally. The SFP ports are
labeled ETH 1/2 and ETH 2/2.
When installing or removing SFP modules, observe these guidelines:
•
Removing and installing an SFP module can shorten its useful life. Do not remove and insert any
module more often than is absolutely necessary.
•
To prevent ESD damage, follow your normal board and component handling procedures when
connecting cables to the switch and other devices.

The router ships with one omni-directional, monopole WiFi antenna already installed and connected
internally to the router internal short-range access point. The router WiFi link enables users to connect
to the router from anywhere within WiFi range. For example, a technician can check the status of the
router from the ground (instead of having to physically open the router on its poletop installation) by
remotely connecting to the router over the WiFi link.
The WiFi antenna is a field replaceable component. The Cisco Product ID (PID) for the Wifi antenna is
ANT-MP-INT-OUT-M.

WiFi antenna location
Connected Grid Module Antennas
In addition to the two fixed antennas (GPS and WiFi), the router supports up to seven additional
antennas, which provide connectivity to the Connected Grid modules installed in the router. Each
module requires one or two antennas, which are mounted on the exterior of the router and connected
through chassis antenna ports to the module installed inside the router.
The router supports up to four Cisco Connected Grid modules. Each module requires one antenna or two
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

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.
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

You can use router software command line interface (CLI) to view the status of System Status LED
described in the section System Status (SYS) LED, page 12-2. During normal operation, the router can
be installed at the top of an outdoor pole or other inaccessible location, and you might not be able to
view SYS LED on the router hardware. In this case, you can view the status of the LED from a remote
location using the router CLI.
This section includes these commands:
•
show led, page 12-8
•
show interface, page 12-8
show led
Use the show led command in any command mode to view the status of the router SYS LED.
One SYS LED is located on the router exterior, as shown in Figure 12-1 and the other is located inside
the router chassis, as shown in Figure 12-2.
The values displayed in the System LED field are described in the section System Status (SYS) LED,
page 12-2.

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 Connecting the Console Port, page 6-15 in the chapter
Installing the Router.
About the Console Port
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
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
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 Console Port, page 2-15 in the chapter Router Hardware Description.)
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.
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 OS) or PuTTY.
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.
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.
Step 1
Use the Finder to go to Applications > Utilities > Terminal.
