Connecting Data Cables

Transcription

1 CHAPTER 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 5 ESR. Connecting a Video Terminal to the PRE Console Port The PRE module has an asynchronous serial (EIA/TIA-) RJ-5 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 5 ESR. The console cable kit contains: One RJ-5 to RJ-5 crossover cable One RJ-5 to DB-5 (female) adapter One RJ-5 to DB-9 (female) adapter A crossover cable reverses pin connections from one end to the other. In other words, it connects pin (at one end) to pin 8 (at the other end), pin to pin 7, pin 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 ) 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. -

2 Connecting a Video Terminal to the PRE Console Port Chapter To connect a video terminal to the console port on a PRE module: Step Connect the RJ-5 crossover cable to the serial RJ-5 console port on the PRE module (Figure -). Figure - Console Port Connection on the PRE Module 7 -

3 Chapter Connecting a Video Terminal to the PRE Console Port Step Connect the other end of the RJ-5 crossover cable to the RJ-5 adapter (Figure -). If your terminal is equipped with a: DB-5 serial connector, use the RJ-5-to-DB-5 adapter. DB-9 serial connector, use the RJ-5-to-DB-9 adapter.

4 Creating Remote Access with an Auxiliary Modem Connection Chapter Creating Remote Access with an Auxiliary Modem Connection You can use the asynchronous EIA/TIA- serial port to connect a modem to the PRE to set up remote administrative access. Use the following procedure to connect the Cisco 5 chassis to a modem. Step Connect one end of the modem cable to the RJ-5 port on the primary PRE, labeled (Figure -). Figure - Connecting Modem Cable to Auxiliary Port 57 Step Connect the other end of the cable to your modem. -

5 Chapter Making Ethernet Network Management Connections Making Ethernet Network Management Connections The PRE module provides an Ethernet port that you can connect to a BASE-T or BASE-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 BASE-T Ethernet Network To connect to a BASE-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-5 (male) to RJ-5 (male) straight-through cable -ohm category,, or 5, no longer than 8 feet ( 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 ) 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 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. -5

6 Making Ethernet Network Management Connections Chapter To connect the PRE to a BASE-T Ethernet LAN: Step Connect one end of the Ethernet cable to the RJ-5 port on the primary PRE, labeled ETH (Figure -). Figure - Connecting BASE-T to Ethernet Port 6 Step Step Connect the other end of the Ethernet cable to any unoccupied port on the Ethernet hub. 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 BASE-T Ethernet LAN. -6

7 Chapter Making Ethernet Network Management Connections Connecting to a BASE-T Ethernet Network To connect to a BASE-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-5 (male) to RJ-5 (male) straight-through cable. -ohm category 5 cable not longer than 8 feet ( 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 ) 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 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 5 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 BASE-T ports is highly recommended. In addition, use of shielded interconnection cables for the BASE-T ports is required to meet Telcordia (formerly Bellcore) GR-89 CORE Section.5.9 and ETSI Section 5... (intrabuilding lightning surge). The RJ-5 port on the PRE is configurable for -Mbps full-duplex or half-duplex operation (half-duplex is the default) and supports IEEE 8., Ethernet, and IEEE 8.u interfaces compliant with BASE-T specifications. -7

8 Making Ethernet Network Management Connections Chapter To connect the PRE to a BASE-T Ethernet LAN: Step Connect one end of the Ethernet cable to the RJ-5 port on the primary PRE, labeled ETH (Figure -5). Figure -5 Connecting BASE-T to Ethernet Port 6 Step Step Connect the other end of the Ethernet cable to any unoccupied port on the Ethernet hub. 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 BASE-T Ethernet LAN. -8

9 Chapter 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 5 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 T Line Card Connections, page -9 OC- POS Line Card Connections, page - Gigabit Ethernet Line Card Connections, page - Channelized OC- Line Card Connections, page -5 OC- ATM Line Card Connections, page -7 Channelized STM- Line Card Connections, page -8 Note For line cards not illustrated in this section, see the specific line card installation guide for additional information about cable connections. Channelized T Line Card Connections Each channelized T line card supports six channelized DS ports. The ports are served by pairs of BNC connectors on the T/E extender cards at the rear of the chassis (Figure -6). Warning The DS 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 DS ports to a network termination unit (NTU). NTU devices should comply with appropriate national safety standards such as UL 95, CSA 95, IEC 95, and AS 6. -9

11 Chapter OC- POS Line Card Connections The OC- POS line card provides a trunk uplink that supports up to 6 Mbps over a standard SONET/SDH interface. Table - describes the cable requirements for the OC- POS line card. Table - OC- POS Cable Specifications Connector Type Fiber Type Wavelength Core Size SC Single mode nm 8 to microns Cable Distance (Intermediate Reach) 9, ft (5 km) 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- POS line card: Step Step Remove the protective cap from the OC-/STM- fiber optic cable connectors. Attach the fiber optic cable to the OC- 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 -7). -

(7 km) to 6 miles ( km). Mode-conditioning patch cord (CAB-GELX-65 or equivalent) is required. If you use an ordinary patch cord with multimode fiber (MMF), BASE-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 6.5-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 98 ft ( m).. km over premium single mode fiber or dispersion shifted single mode fiber. 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. -

14 Chapter Step Insert the GBIC into the GE line card port until the tabs lock into place (Figure -8). Note The GBIC is keyed and can only be fully inserted one way. If you can insert the GBIC only ¼ of the way into the port, then remove it, turn it over, and reinsert it into the port.
