Connecting Data Cables

This chapter provides detailed instructions for connecting a console terminal, an Ethernet LAN for management, and for most types of network data cables to the Cisco 10005 ESR.

Connecting a Video Terminal to the PRE Console Port

The PRE module has an asynchronous serial (EIA/TIA-232) RJ-45 console port labeled CON on its front panel. You can connect this port to most types of video terminals by using the console cable kit that is included with your Cisco 10005 ESR. The console cable kit contains:

•One RJ-45 to RJ-45 crossover cable

•One RJ-45 to DB-25 (female) adapter

•One RJ-45 to DB-9 (female) adapter

A crossover cable reverses pin connections from one end to the other. In other words, it connects pin 1 (at one end) to pin 8 (at the other end), pin 2 to pin 7, pin 3 to pin 6, and so on. You can identify a crossover cable by comparing the two modular ends of the cable. Hold the cable ends in your hand, side by side, with the tabs at the back. Ensure that the wire connected to the outside (left) pin of the left plug (pin 1) is the same color as the wire connected to the outside (right) pin of the right plug (pin 8).

Note Each PRE must be set up with a console port connection (typically to a terminal server) if you are running a redundant configuration in the chassis.

To connect a video terminal to the console port on a PRE module:

Step 1 Connect the RJ-45 crossover cable to the serial RJ-45 console port on the PRE module (Figure 2-1).

Figure 2-1 Console Port Connection on the PRE Module

Step 2 Connect the other end of the RJ-45 crossover cable to the RJ-45 adapter (Figure 2-2). If your terminal is equipped with a:

•DB-25 serial connector, use the RJ-45-to-DB-25 adapter.

•DB-9 serial connector, use the RJ-45-to-DB-9 adapter.

Figure 2-2 Connecting an RJ-45-to-DB-9 Console Cable Adapter

Step 3 Connect the adapter to your video terminal to complete the cable connection.

Step 4 Power on your video terminal.

Step 5 Configure your video terminal to match the following default console port settings:

•9600 baud

•8 data bits

•No parity generation or checking

•1 stop bit

•No flow control

Creating Remote Access with an Auxiliary Modem Connection

You can use the asynchronous EIA/TIA-232 serial port to connect a modem to the PRE to set up remote administrative access. Use the following procedure to connect the Cisco 10005 chassis to a modem.

Step 1 Connect one end of the modem cable to the RJ-45 port on the primary PRE, labeled AUX (Figure 2-3).

Figure 2-3 Connecting Modem Cable to Auxiliary Port

Step 2 Connect the other end of the cable to your modem.

Making Ethernet Network Management Connections

The PRE module provides an Ethernet port that you can connect to a 10BASE-T or 100BASE-T LAN for network management.

Note Each PRE must have an Ethernet port connection (typically to the same Ethernet hub) if you have two PREs installed in the chassis.

Connecting to a 10BASE-T Ethernet Network

To connect to a 10BASE-T network, obtain the following additional equipment (not included):

•An Ethernet hub (such as a Cisco Micro Hub)

•An Ethernet cable that meets the following specifications:

–RJ-45 (male) to RJ-45 (male) straight-through cable

–100-ohm category 3, 4, or 5, no longer than 328 feet (100 meters)

You can identify a straight-through Ethernet cable either by using a cable tester or by making a visual inspection. To make a visual inspection, hold the two ends of a cable side by side, with the tab for each at the back.

•The wire connected to the left-most pin (pin 1) on one connector should be the same color as the wire connected to the left-most pin on the other connector.

•The same rule applies to pins 2 through 8 on each connector. The color of the wire attached to a pin on one connector should match the color of the wire attached to the corresponding pin on the other connector.

To connect the PRE to a 10BASE-T Ethernet LAN:

Step 1 Connect one end of the Ethernet cable to the RJ-45 port on the primary PRE, labeled ETH (Figure 2-4).

Figure 2-4 Connecting 10BASE-T to Ethernet Port

Step 2 Connect the other end of the Ethernet cable to any unoccupied port on the Ethernet hub.

Step 3 Check the LNK (Link) LED on the PRE faceplate (next to the ETH) port.

This LED lights (green) if the PRE is correctly connected to the 10BASE-T Ethernet LAN.

Connecting to a 100BASE-T Ethernet Network

To connect to a 100BASE-T network, obtain the following additional equipment (not included):

•An Ethernet hub (such as a Cisco Micro Hub)

•An Ethernet UTP cable that meets the following specifications:

–RJ-45 (male) to RJ-45 (male) straight-through cable.

–100-ohm category 5 cable not longer than 328 feet (100 meters). (we do not supply Category 5 UTP cables; these cables are available commercially.)

You can identify a straight-through Ethernet cable either by using a cable tester or by making a visual inspection. To make a visual inspection, hold the two ends of a cable side by side, with the tab for each at the back.

•The wire connected to the left-most pin (pin 1) on one connector should be the same color as the wire connected to the left-most pin on the other connector.

•The same rule applies to pins 2 through 8 on each connector. The color of the wire attached to a pin on one connector should match the color of the wire attached to the corresponding pin on the other connector.

Caution If the Cisco 10005 ESR is used in an environment in which lightning-induced transients are likely to couple to the signal lines, use of shielded interconnection cables for the 100BASE-T ports is highly recommended. In addition, use of shielded interconnection cables for the 100BASE-T ports is required to meet Telcordia (formerly Bellcore) GR-1089 CORE Section 4.5.9 and ETSI Section 5.2.2.2 (intrabuilding lightning surge).

The RJ-45 port on the PRE is configurable for 100-Mbps full-duplex or half-duplex operation (half-duplex is the default) and supports IEEE 802.3, Ethernet, and IEEE 802.3u interfaces compliant with 100BASE-T specifications.

To connect the PRE to a 100BASE-T Ethernet LAN:

Step 1 Connect one end of the Ethernet cable to the RJ-45 port on the primary PRE, labeled ETH (Figure 2-5).

Figure 2-5 Connecting 100BASE-T to Ethernet Port

Step 2 Connect the other end of the Ethernet cable to any unoccupied port on the Ethernet hub.

Step 3 Check the LNK (Link) LED on the PRE (next to the ETH port).

This LED lights (green) if the PRE is correctly connected to the 10BASE-T Ethernet LAN.

Making Data Network Connections

Make external data network connections through BNC connectors on the rear of the router, and through the front panel ports on line cards.

When you connect external cables to the Cisco 10005 chassis, keep in mind the following guidelines:

•To reduce the chance of interference, avoid crossing high-power lines with any interface cables.

•Verify all cabling limitations (particularly distance) before powering on the system.

The remainder of this section contains instructions for making these connections:

•Channelized T3 Line Card Connections

•OC-12 POS Line Card Connections

•Gigabit Ethernet Line Card Connections

•Channelized OC-12 Line Card Connections

•OC-12 ATM Line Card Connections

•Channelized STM-1 Line Card Connections

Note For line cards not illustrated in this section, see the specific line card installation guide for additional information about cable connections.

Channelized T3 Line Card Connections

Each channelized T3 line card supports six channelized DS3 ports. The ports are served by pairs of BNC connectors on the T3/E3 extender cards at the rear of the chassis (Figure 2-6).

Warning The DS3 ports are not intended to be connected to cables that run outside the building where the system is installed. To make any connections outside the building, you must connect the DS3 ports to a network termination unit (NTU). NTU devices should comply with appropriate national safety standards such as UL 1950, CSA 950, IEC 950, and AS 3260.

Figure 2-6 Channelized T3 Connections

Each DS3 port requires two 75-ohm coaxial cables (transmit and receive) with bayonet-style twist-lock BNC connectors.

Attach the cables to the BNC connectors on the chassis, being sure that you attach the Tx and Rx cables to the corresponding Tx and Rx connectors on the port.

Note Do not make connections to the left-most BNC connectors on each extender card, ports 6 and 7. These ports are inoperative.

OC-12 POS Line Card Connections

The OC-12 POS line card provides a trunk uplink that supports up to 622 Mbps over a standard SONET/SDH interface. Table 2-1 describes the cable requirements for the OC-12 POS line card.

Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures.

To connect the fiber cable to the OC-12 POS line card:

Step 1 Remove the protective cap from the OC-12/STM-4 fiber optic cable connectors.

Step 2 Attach the fiber optic cable to the OC-12 port receptacles on the line card, being sure that you connect the Tx and Rx ends of the cable to the corresponding Tx and Rx connectors on the port (Figure 2-7).

Figure 2-7 Connecting the Cable to the OC-12 POS Port

Gigabit Ethernet Line Card Connections

The single-port gigabit Ethernet (GE) line card provides a trunk uplink running at 1 Gbps in full duplex mode to devices such as content servers and Web caches.

The port uses a Gigabit Interface Converter (GBIC) that supports gigabit Ethernet rates on a variety of gigabit Ethernet interface types (SX, LX/LH, ZX). Plug the GBIC into the port on the line card, then connect the fiber cable to the GBIC.

Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures.

Table 2-2 lists the GE line card GBICs and their respective cable types and lengths.

1 Mode-conditioning patch cord (CAB-GELX-625 or equivalent) is required. If you use an ordinary patch cord with multimode fiber (MMF), 1000BASE-LX/LH GBICs, and a short link distance (tens of meters), this can cause transceiver saturation, resulting in an elevated bit error rate (BER). In addition, when you use the LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the GBIC and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 ft (300 m).

To install a GBIC and connect a fiber cable to the GBIC:

Note If a GBIC is already installed in the GE line card, begin this procedure at
Step 2.

Step 1 Insert the GBIC into the GE line card port until the tabs lock into place (Figure 2-8).

Note The GBIC is "keyed" and can only be fully inserted one way. If you can insert the GBIC only ΒΌ of the way into the port, then remove it, turn it over, and reinsert it into the port.

Figure 2-8 Inserting the GBIC

Step 2 Remove the protective plug from the GBIC by pulling it off.

Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures.

Step 3 Attach the fiber optic cable to the GBIC port (Figure 2-9).
