Caution Do not place anything on top of the Cisco Optical Regenerator that weighs more than 10 pounds (4.5 kilograms (kg)). More weight on top could damage the regenerator.

Choosing Interface Cables

The cable accessory kit contains the cables you need to connect the Cisco Optical Regenerator to another device. You will need the following cables to connect the Cisco Optical Regenerator to other devices on the network:

To order additional cables, see the "Service and Support" section in the "About This Guide" preface. For cable pinouts, refer to the "Cable Specifications."

Note Single-mode long reach simplex cables with SC connectors are available from the following cable vendors: AMP, Anixter, AT&T, Red-Hawk, and Siemens. These cables are not available from Cisco Systems.

For SONET/SDH connections to the regenerator:

Step 1 Use two simplex SC single-mode long-reach fiber-optic cables to connect the OC-48 regeneration ports to an OC-48 line card that is installed in the first Cisco Series 12000 series GSR.

Step 2 Use two simplex SC single-mode long-reach fiber-optic cables to connect the OC-48 regeneration ports to an OC-48 line card that is installed in the second Cisco Series 12000 series GSR.

Figure 4-4 shows a simplex SC cable connector. Be sure to observe the receive (Rx) and transmit (Tx) cable relationship, which means that an Rx port on one line card must be connected to a Tx port on the next line card.


Figure 4-4: Attaching Simplex Fiber Cables


Note Fiber-optic connectors must be free of dust, oil, and other contaminants. Carefully clean the fiber-optic connectors using an alcohol wipe or other suitable cleanser.
Warning Invisible laser radiation can be emitted from the aperture of the port when no cable is connected. Avoid exposure to laser radiation and do not stare into open apertures.
Warning Class 1 laser product (single-mode).

Inserting the Cable-Management Bracket

The cable-management bracket organizes the interface cables that lead into and away from the regenerator. Be sure to keep the interface cables out of the way of other cables and free of sharp bends.

Note Excessive bending in an interface cable can degrade performance.

You can attach the cable-management bracket to the left front side of the regenerator in the area over the Ethernet and console ports, as shown in Figure 4-5.


Figure 4-5: Cable-management Bracket


Follow these steps to insert the cable-management bracket:

Step 1 Turn the regenerator so that the front panel is toward you. Locate the slit opening over the Ethernet and console ports.

Step 2 Insert the flat end of the bracket into the slit, with the rounded end pointing up. Push the flat end into the bend in the bracket.

Step 3 Rotate the bracket downward, so that it is parallel to the regenerator.

Step 4 Guide the interface cables toward the left side of the regenerator, away from the SC connectors, through the rounded end of the cable-management bracket.

Connecting to Your Network

This section describes options for connecting the Cisco Optical Regenerator to your network. Use one of these methods to configure the regenerator for local or network connections by:

Note The Cisco Optical Regenerator is available with an AC or a DC power supply. The examples in this section show a Cisco Optical Regenerator with an AC power supply.
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.
(For translated versions of this warning, see the Regulatory Compliance and Safety Information for the Cisco Optical Regenerator document that accompanied your regenerator.)
Warning This equipment must be grounded when there is an AC or a DC power supply. Ensure that the regenerator is connected to a system (earth) grounding receptacle during normal use. For details, see "System Grounding Connection Guidelines" section.
Warning The console ports contain safety extra-low voltage (SELV) circuits.

Using the Console Port

The following sections describe hardware configuration options for connecting the Cisco Optical Regenerator console port to other devices.

Use a console port cable (RJ-45 rollover cable) to connect a PC com or serial port directly to the regenerator console port. After connecting a PC to the console port, you can use suitable terminal emulation software to communicate with the regenerator. (See Figure 4-6.)


Figure 4-6: Connecting the Cisco Optical Regenerator to a PC


Connecting through a Modem

You can use a PC with an internal or external modem to configure the regenerator that is located at a remote site.

Step 1 Connect a console port cable (RJ-45 rollover cable) to the console port on the Cisco Optical Regenerator.

Step 2 Connect the opposite end of the console port cable with an RJ-45 to DB-25 adapter (EIA/TIA-232) to a modem.

Step 3 Dial the telephone number of the modem that is connected to the regenerator. You can configure the regenerator remotely through the PC modem. (See Figure 4-7).


Figure 4-7: Connecting a Modem to the Console Port


Connecting the Cisco Optical Regenerator to a Terminal Server

You can link regenerator's console port to a LAN network through a terminal server. The Cisco terminal server has a maximum of 16 serial port lines. Each serial port line is numbered one through sixteen (1 through 16). The terminal server serial port line number becomes the terminal server address.

To configure the Cisco Optical Regenerator to a terminal server:

Step 1 Use an RJ-45 console cable to connect the console port on the regenerator to a serial port on a terminal server. For the purpose of this example, the regenerator is connected to serial port line 5 of the terminal server.

Step 2 Connect the terminal server serial port to the PC terminal serial port.

Step 3 Power on the regenerator.

Step 4 To boot the regenerator, you can either:

    Router# telnet line 5
Router#
 

    Router# <terminal server name> 2005
Router# <terminal server IP address> 2005
Router#

Figure 4-8 shows the Cisco Optical Regenerator connected to a terminal server and a PC terminal serial port.

Using OC-48 Regeneration Ports

This section describes a Cisco Optical Regenerator and an OC-48 line card installed in each Cisco 12000 series GSR at two remote sites.

Two single simplex SC connector cables are usually tied together as pairs, so they will appear as one cable with Rx and Tx connectors at each end. Be sure to disconnect and reconnect the cables using the receive (Rx) and transmit (Tx) cabling relationship.

To connect the OC-48 line cards that are installed in two Cisco 12000 series GSRs:

Step 1 Connect the simplex SC cable connector to the regenerator's left Tx OC-48 regeneration port on side 0. Connect the simplex SC cable connector to the regenerator's left Rx OC-48 regeneration port on side 0.

Step 2 Connect the opposite end of the simplex SC cable to the left Rx SC connector on an OC-48 line card. Connect the opposite end of the simplex SC cable to the left Tx SC connector on an OC-48 line card.

Step 3 Connect a simplex SC cable connector to the regenerator's right Tx OC-48 regeneration port on side 1. Connect a simplex SC cable connector to the regenerator's right Rx OC-48 regeneration port on side 1.

Step 4 Connect the opposite end of the simplex SC cable to the right Rx SC connector on an OC-48 line card. Connect the opposite end of the simplex SC cable to the right Tx SC connector on an OC-48 line card.

Step 5 Repeat steps 1 and 4 for all OC-48 line cards that will be connected to a Cisco Optical Regenerator on the network.

Step 6 Use a PC or VTY terminal to configure the regenerator and communicate with other network devices.

Figure 4-9 shows the regenerator configured to OC-48 line cards installed in two Cisco 12000 series GSRs.
