Before following any installation procedures in this section, read these topics:

blank.gifInstallation Site Preparation

blank.gifInstallation Safety Information

blank.gifConnecting the Router to Power

blank.gifPreventing Electrostatic Discharge Damage

blank.gifCabling Guidelines

Installation Site Preparation

The procedures in this section assume that you prepared the installation site according to the information in Installation Safety and Site Preparation.

Installation Safety Information

Before performing any of the tasks in this section, read the safety warnings in this section and in Installation Safety and Site Preparation.

Connecting the Router to Power

Before you make network connections, your router should be connected to the AC power source and powered on as described in Connecting the Router to Power.

Preventing Electrostatic Discharge Damage

Many of the components discussed in this chapter are sensitive to electrostatic discharge (ESD) damage, which can occur when electronic cards or components are handled improperly, which can result in complete or intermittent failures.

To prevent ESD damage, follow these guidelines:

blank.gifAlways use an ESD wrist or ankle strap and ensure that it makes good skin contact.

blank.gifConnect the equipment end of the strap to an unfinished chassis surface.

blank.gifPlace a removed 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.

blank.gifAvoid 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.

blank.gifDo not remove the wrist strap until the installation is complete.

Cabling Guidelines

Follow these guidelines for using cables with the router:

blank.gifFollow the recommended router orientation when mounting it to prevent cable strain. For more information, see the Router Orientation When Mounting.

blank.gifPosition cables so that they do not place strain on the router connectors.

blank.gifOrganize cables into bundles when necessary to avoid intertwining.

blank.gifInspect cables to ensure adequate routing and bend radius.

blank.gifInstall cable ties that comply with your site requirements.

Basic Network Connections

This section describes basic router installation steps. These are the minimum installation steps required for the router to begin operating within the field area network.

Connect to the Ethernet Network

The steps in this section require that an Ethernet network connection is available at the installation location. There are two options for connecting to the Ethernet network:

blank.gifConnecting the Ethernet Ports

blank.gifConnecting the SFP Ports

Connecting the Ethernet Ports

The router features four Fast Ethernet (FE) ports and two Gigabit Ethernet (GE) ports for connecting the router to an Ethernet network through a hub or switch.

blank.gifSee Figure 1 for the Ethernet port locations.

blank.gifOne or two Ethernet cables are typically provided with the router. Additional cables and transceivers can be ordered from Cisco. For ordering information, contact your reseller or Cisco customer service.

blank.gifThe GE ports (ETH 2/1 and ETH 2/2) have identical labels to the SFP ports because the SFP ports share physical ports with the GE ports. For detailed information about how to use these ports (called combo ports), see Combo Ports.

Warning: Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001

Connecting the SFP Ports

Small Form-Factor Pluggable (SFP) modules are devices that plug into the router SFP connectors shown in Figure 2. 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:

blank.gifWrist strap or other personal grounding device to prevent ESD occurrences.

blank.gifAntistatic mat or antistatic foam to set the transceiver on.

blank.gifFiber-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

This section describes how to install SFP modules. SFP modules are inserted into the SFP ports shown in Figure 2.

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:

blank.gifRemoving and installing an SFP module can shorten its useful life. Do not remove and insert any module more often than is absolutely necessary.

blank.gifTo prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the switch and other devices.

To install SFP modules:

1.blank.gif Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

2.blank.gif For fiber-optic SFP modules, remove the dust plugs and store them in a clean location for reuse.

3.blank.gif Position the SFP transceiver module in front of the socket opening, and insert the SFP into the socket until you feel the connector latch into place.

Connecting the Alarm Port

The alarm port provides data about fatal or severe errors that can cause the system software to crash.

The alarm port is connected to a normally closed solid state relay. Cisco CG-OS writes to a hardware port and the relay contact opens. If the system enters into a ROM monitor (ROMmon) or watchdog reset state, the relay contacts close. The closing contacts alert the alarm annunciator or monitor that a Cisco CG-OS crash has occurred.

If interfaces fail or other non-fatal errors occur, the alarm port does not respond. Continue to use SNMP to manage these types of errors.

Connecting

blank.gifYou can connect this port while the router is operating normally.

blank.gifIf you use an alarm system on your network, connect the alarm port to an alarm system with an alarm cable that you provide.
