Rack-Mounting the Router Chassis

The router chassis can be installed in either a front-mounted position or a center-mounted position as shown in Figure 3-12.

Figure 3-12 Front-Mount and Center-Mount Rack Positions

In a front-mounted position, the chassis rack-mounting flanges are secured directly to the rack posts.

In a center-mounted position, an optional set of center-mount brackets are secured to the rack posts and the chassis rack-mounting flanges are then secured to the center-mount brackets. The center-mounted position moves the center of gravity of the chassis closer to the vertical axis of the rack posts, which adds to the security and stability of the rack installation.

Verifying Rack Dimensions

Before you install the chassis, measure the space between the vertical mounting flanges (rails) on your equipment rack to verify that the rack conforms to the measurements shown in Figure 3-13.

Step 1 Mark and measure the distance between two holes on the left and right mounting rails.

The distance should measure 18.31 inches ± 0.06 inches (46.5 cm ± 0.15 cm).

Note Measure for pairs of holes near the bottom, middle and top of the equipment rack to ensure that the rack posts are parallel.

Step 2 Measure the space between the inner edges of the left front and right front mounting flanges on the equipment rack.

The space must be at least 17.7 inches (45 cm) to accommodate the chassis which is 17.25 inches (43.8 cm) wide and fits between the mounting posts on the rack.

Figure 3-13 Verifying Equipment Rack Dimensions

Installing Rack-Mount Brackets—Optional

The router accessory kit ships with a pair of rack-mount brackets that can be used as a temporary aid to bear the weight of the chassis while it is being positioned and secured in the equipment rack. Using these mounting brackets is optional, but highly recommended to make installation easier. The rack-mount brackets can be left in place after the chassis is installed.

Note Before installing the rack-mount brackets, make sure you have performed the measurements described in "Verifying Rack Dimensions" section.

Use the following procedure to install the rack-mount brackets.

Step 1 Determine the location in which you want to position the chassis in the rack, and mark holes at the same height on both the left and right rack rails.

Step 2 Install the right rack-mount bracket (Figure 3-14).

a. Align the bottom screw hole of the bracket with the marked screw hole at the bottom of the rack and finger tighten a screw in that hole.

b. Finger-tighten a second screw in the top hole of the bracket.

c. Use a screwdriver to tighten both screws securely.

Step 3 Repeat Step 2 for the left rack-mount bracket.

Step 4 Use a level to verify that the tops of the two brackets are level, or use a measuring tape to verify that both brackets are the same distance from the top of the rack rails.

Figure 3-14 Installing the Left and Right Rack-Mount Brackets

Installing Center-Mount Brackets—Optional

If you plan to install the router in the center-mount position, you must install the center-mount brackets to the rack rails first. If you do not plan to use the optional center-mount brackets, proceed directly to the "Installing the Chassis in the Rack" section.

The optional center-mount bracket installation kit ships in the accessories box included with the router and contains the following:

•Two center-mount brackets.

•10 (minimum) Phillips binderhead screws (usually provided with the bracket kit) to secure the brackets to the mounting flanges (also called rails) in the rack. Five screws should be installed on each bracket.

Contact a Cisco service representative for assistance if any parts are missing.

Note Before installing the center-mount brackets, make sure you have performed the measurements described in "Verifying Rack Dimensions" section.

Use the following procedure to install the center-mount brackets to the rack rails.

Step 1 Determine the location in which you want to position the bottom of the router chassis in the rack, and mark holes at the same height on both the left and right rack rails.

Step 2 Identify the orientation of the left and right center-mount brackets (Figure 3-15).

Figure 3-15 Center-Mount Brackets

Step 3 Install the right center-mount bracket (Figure 3-16).

a. Align the bottom screw hole of the bracket with the marked screw hole at the bottom of the rack and finger tighten a screw in that hole.

b. Finger-tighten a second screw in the top hole of the bracket.

Caution Unoccupied card slots in the line card and RP card cage must have a blank filler panel installed for electromagnetic compatibility (EMC) and to ensure proper air flow through the chassis.

Step 2 Repeat Step 2 for each line card.

Caution Unoccupied card slots must have a blank filler panel installed for electromagnetic compatibility (EMC) and to ensure proper air flow through the chassis. If the faceplate of a line card does not completely fill the card slot opening, a narrow card filler panel must be installed for electromagnetic compatibility (EMC) and to ensure proper air flow through the chassis.

Step 3 Go to the "Connecting Line Card Network Interface Cables" section to connect the network interface cables.

Connecting Line Card Network Interface Cables

This section describes how to route the network interface cables through the
router cable-management system and attach the network interface cables to the line card ports.

This procedure uses an 8-port fiber-optic Fast Ethernet card as an example to describe how to attach a network interface cable to a line card port and route the cable through the cable-management system. Depending on which line cards are installed in your system, your cable connection procedure might differ slightly from this example. For cable connection information for your specific line card, refer to the installation and configuration note for that line card.

Note You can access the most current Cisco line card documentation on the World Wide Web at: http://www.cisco.com.

Use the following procedure as an example to route the network interface cables through the cable-management system and connect them to the line card.

Step 1 Route an interface cable across the horizontal cable-management tray, through the cable tray opening to connect it to the line card:

•For legacy fiber-optic line cards, go to Step 2.

•For current fiber-optic line cards, go to Step 6.

Step 2 Install a plastic bend-radius clip on the strain-relief ferrule on the connector (see blow-out in Figure 3-27).

Note The bag of bend-radius clips (Part Number 800-06119-01) in the accessories box that shipped with your router contains two sizes of bend-radius clips. The clip size is determined by the diameter of the strain-relief ferrule on the cable connectors. Use the size that provides the most secure fit on the strain-relief ferrule on the cable connectors in use at your site.

Step 3 Insert the cable connector into its assigned port.

Step 4 Route the cable up the cable-management bracket and carefully press the cable into the channel so it is held in place by the cable clips (Figure 3-27b).

Step 5 Repeat Steps 3 through 5 for each additional cable connection to that line card.

Figure 3-27 Connecting a Network Interface Cable to a Legacy Line Card

Step 6 Insert all cables into their assigned ports.

Step 7 Place several evenly spaced velcro straps through slots on the cable-management bracket (Figure 3-28a).

Step 8 Route the cables alongside the cable-management bracket and secure them with the velcro straps as appropriate (Figure 3-28b).

Caution Make sure the interface cables do not have any kinks or sharp bends which can destroy or degrade the ability of the optical fiber to propagate the signal-encoded beam of light accurately from one end of the cable to the other. Always allow adequate strain relief in the interface cable.

Figure 3-28 Current Style Cable Management Bracket

Connecting GRP Route Processor Cables

This section describes how to connect cables to the console, auxiliary, and Ethernet ports on the GRP. The console and auxiliary ports are both asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. For example, most modems are asynchronous devices.

Figure 3-29 shows an example of a data terminal and modem connections.

Figure 3-29 GRP Console and Auxiliary Port Connections

Caution The ports labeled Ethernet, 10BASE-T, Token Ring, Console, and AUX are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits.

Note RP cables are not available from Cisco, but are available from any commercial cable vendor.

Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect all console, auxiliary, and Ethernet interfaces only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

Connecting to the GRP Console Port

The system console port on the GRP is an EIA/TIA-232 DCE DB-25 receptacle for connecting a data terminal to perform the initial configuration of the router. The console port requires a straight-through RJ-45 cable.

See the "GRP Auxiliary and Console Port Connections" section on page 2-23 for additional information about the GRP console port.

Use the following procedure to connect a data terminal to the GRP console port.

Step 1 Set your terminal to these operational values: 9600 bps, 8 data bits, no parity, 2 stop bits (9600 8N2).

Step 2 Power off the data terminal.

Step 3 Attach the terminal end of the cable to the interface port on the data terminal.

Step 4 Attach the other end of the cable to the GRP console port.

Step 5 Power on the data terminal.

Connecting to the GRP Auxiliary Port

The auxiliary port on the GRP is an EIA/TIA-232 DTE DB-25 plug for connecting a modem or other DCE device (such as a channel service unit/data service unit (CSU/DSU) or another router) to this router.

See the "GRP Auxiliary and Console Port Connections" section on page 2-23 for additional information about the GRP auxiliary port.

Use the following procedure to connect an asynchronous serial device to the GRP auxiliary port.

Step 1 Power off the asynchronous serial device.

Step 2 Attach the device end of the cable to the interface port on the asynchronous serial device.

Step 3 Attach the other end of the cable to the GRP auxiliary port.

Step 4 Power on the asynchronous serial device.

Connecting to the GRP Ethernet Port

The Ethernet port on the GRP supports two types of Ethernet ports (as shown in Figure 3-30):

•A media-independent interface (MII), 40-pin, D-type receptacle.

•A media-dependent interface (MDI) RJ-45 receptacle.

The RJ-45 and MII receptacles on the GRP represent two physical connection options for only one Ethernet interface; therefore, you can use either the RJ-45 connection or the MII connection, but not both simultaneously.

Caution The GRP can support only one Ethernet connection at a time. To prevent router and network problems, do not connect both RJ-45 and MII cables to the Ethernet receptacles at the same time, and use cables that comply with EIA/TIA-568 standards.

LEDs on the front panel indicate which Ethernet receptacle is active when the GRP is operating. See the "GRP Ethernet Port Connections" section on page 2-26 for additional information about GRP Ethernet ports.

Caution Ethernet ports are primarily used as a Telnet port into the Cisco 12000 series router, and for booting or accessing Cisco IOS software images over a network to which an Ethernet port is directly connected. Cisco Express Forwarding (CEF) functions are switched off by default for security reasons. We strongly caution you to consider the security implications of switching on CEF routing functions on these ports.

Figure 3-30 GRP RJ-45 and MII Ethernet Connections

RJ-45 Connection

Refer to Figure 3-30 and use the following procedure to connect an Ethernet cable to the RJ-45 receptacle on the GRP:

Step 1 Plug the cable directly into the RJ-45 receptacle.

Step 2 Connect the network end of your RJ-45 cable to your transceiver, switch, hub, repeater, DTE, or other external equipment.

Note The Ethernet interfaces on the GRP are endstation devices only, not repeaters.

MII Connection

The MII receptacle requires an external transceiver that permits connection to multimode fiber for 100BASE-FX or 100BASE-T4 physical media. Depending on the type of media you use between the MII receptacle and your switch or hub, the network side of your 100-Mbps transceiver should be appropriately equipped with ST-type connectors (for fiber-optic cables), BNC connectors, and so forth.

Refer to Figure 3-30 and use the following procedure to connect a cable to the MII Ethernet receptacle on the GRP.

Step 1 Connect the cable directly to the MII receptacle, or attach a 100BASE-T transceiver (with the media appropriate to your application) to the MII receptacle.

Step 2 Connect the network end of your MII cable to your transceiver, switch, hub, repeater, DTE, or other external equipment.

Note The Ethernet interfaces on the GRP are endstation devices only, not repeaters.

Connecting PRP Route Processor Cables

This section describes how to connect cables to the console, auxiliary, and Ethernet ports on the PRP. The console and auxiliary ports are both asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. For example, most modems are asynchronous devices.

Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect all console, auxiliary, Ethernet, and BITS (PRP2) interfaces only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

Connecting to the PRP Console Port

The system console port on the PRP is a DCE RJ-45 receptacle for connecting a data terminal to perform the initial configuration of the router. The console port requires a rollover RJ-45 cable.

See the "GRP Auxiliary and Console Port Connections" section on page 2-23 for additional information about the console port.

Refer to Figure 3-31 and use the following procedure to connect a data terminal to the PRP console port.

Step 1 Set your terminal to these operational values: 9600 bps, 8 data bits, no parity, 2 stop bits (9600 8N2).

Step 2 Power off the data terminal.

Step 3 Attach the terminal end of the cable to the interface port on the data terminal.

Step 4 Attach the other end of the cable to the GRP console port.

Step 5 Power on the data terminal.

Connecting to the PRP Auxiliary Port

The auxiliary port on the PRP is a DTE, RJ-45 receptacle for connecting a modem or other DCE device (such as a CSU/DSU or another router) to the router. The asynchronous auxiliary port supports hardware flow control and modem control.

See the "GRP Auxiliary and Console Port Connections" section on page 2-23 for additional information about the auxiliary port.

Refer to Figure 3-31 and use the following procedure to connect an asynchronous serial device to the PRP auxiliary port.

Step 1 Power off the asynchronous serial device.

Step 2 Attach the device end of the cable to the interface port on the asynchronous serial device.

Step 3 Attach the other end of the cable to the PRP auxiliary port.

Step 4 Power on the asynchronous serial device.

Connecting to the PRP Ethernet Ports

Two RJ-45 Ethernet interface receptacles on the PRP provide media-dependent interface (MDI) Ethernet ports. These connections support IEEE 802.3 and IEEE 802.3u interfaces compliant with 10BASE-T and 100BASE-TX standards. The transmission speed of the Ethernet ports is autosensing by default and is user-configurable.

The RJ-45 receptacles on the PRP provide two physical connection options for Ethernet interfaces. To connect cables to the PRP Ethernet interfaces (ports labeled ETH0 and ETH1), attach the Category 5 UTP cable directly to a RJ-45 receptacle on the PRP.

See the "GRP Ethernet Port Connections" section on page 2-26 for additional information about the Ethernet ports.

Note RJ-45 cables are not available from Cisco Systems; they are available from outside commercial cable vendors. Use cables that comply with EIA/TIA-568 standards.

Caution Ethernet ports are primarily used as a Telnet port into the Cisco 12000 series router, and for booting or accessing Cisco IOS software images over a network to which an Ethernet port is directly connected. Cisco Express Forwarding (CEF) functions are switched off by default for security reasons. We strongly caution you to consider the security implications of switching on CEF routing functions on these ports.

Use the following procedure to connect an Ethernet cable to the PRP RJ-45 Ethernet receptacle:

Step 1 Plug the cable directly into the RJ-45 receptacle.

Step 2 Connect the network end of your RJ-45 cable to a switch, hub, repeater, DTE, or other external equipment.

Note The Ethernet interfaces on the PRP are endstation devices only, not repeaters.

Connecting Alarm Display Card Cables

The router alarm display card, which is located above the horizontal cable management tray, has two 25-pin D-subconnectors, labeled Alarm A and Alarm B (Figure 3-32).

Figure 3-32 Alarm Display Card Cable Connection

The alarm subconnectors can be used to connect the router to an external site alarm maintenance system. Any critical, major, and minor alarms generated by the router also energize alarm relays on the alarm card and activate the external site alarm. The alarm relay contacts on the alarm card consist of standard common, normally open, and normally closed relay contacts that are wired to Alarm A and Alarm B connector pins.

Table 2-13 on page 2-43 lists the pin-to-signal correspondence between the connector pins and the alarm card relay contacts. Because alarm contact cables are entirely dependent on installation site circumstances, alarm connector cables are not available from Cisco. For information about alarm connector wiring requirements and the pinouts for the alarm connector interface, see the "Alarm Display Connection Guidelines" section on page 2-42.

Caution Only safety extra-low voltage (SELV) circuits can be connected to the alarm connector. Maximum rating for the alarm circuit is 2 A, 50 VA.

Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, you must use a shielded cable when connecting to the external alarm ports on the alarm card. The shielded cable is terminated by shielded connectors on both ends, with the cable shield material tied to both connectors.

Connecting Power to the Router

Use the one of the following procedures to connect power to your router.

•Connecting Power to an AC-Powered Router

•Connecting Power to a DC-Powered Router

Caution A router must be operated with both of its power modules installed at all times for electromagnetic compatibility (EMC).

Connecting Power to an AC-Powered Router

Use the following procedure to connect the AC power cords to the router.

Note Connect each AC power supply to a dedicated power source (branch circuit). Each AC-input power supply operates between 200 and 240 VAC and requires at least a 20 A service for North American use, or a 13 A service for international use. For more information on AC power cords, see the "Power Connection Guidelines" section on page 2-14.

Step 1 Connect each power cable to the AC power connector on the horizontal trough and secure them with their retention clips (Figure 3-33).

Step 2 Plug each power supply cable into its AC outlet.

Figure 3-33 Connecting Source AC to the AC-Input Power Connector

Connecting Power to a DC-Powered Router

This section contains the procedures to connect the DC source power cables to either a 2400 W or 2800 W DC-powered router.

The color coding of source DC power cable leads depends on the color coding of the site DC power source. Because there is no color code standard for source DC wiring, you must be sure that power source cables are connected to the PDU with the proper positive (+) and negative (-) polarity:

•In some cases, the source DC cable leads might have a positive (+) or a negative (-) label. This is a relatively safe indication of the polarity, but you must verify the polarity by measuring the voltage between the DC cable leads. Be sure that the positive (+) and negative (-) cable leads match the positive (+) and negative (-) labels on the PDU when making the measurement.

•A green (or green and yellow) cable typically indicate that it is a ground cable.

Caution DC PEMs contains circuitry to trip the breaker on the PEM if the PEM detects a reverse polarity condition. No damage should occur from reverse polarity, but you should correct a reverse-polarity condition immediately.

Note The length of the cables depends on the location of your router in relation to the source of DC power. These cables and the cable lugs used to attach the cables to the router chassis are not available from Cisco Systems. They are available from any commercial cable vendor. For more information on site power and source DC cable requirements, see the "Power Connection Guidelines" section on page 2-14.

Warning To ensure that power remains off while you are performing this procedure, tape the DC circuit breaker switch in the off (0) position.

Reconnect the DC power cables:

•For 2400 W PDUs—Go to 2400 W DC Connections.

•For 2800 W PDUs—Go to 2800 W DC Connections.

2400 W DC Connections

Use the following procedure to connect the DC source power cables to a 2400 W powered router.

Step 1 Remove the clear plastic safety cover that fits over the DC power connection terminal studs.

Step 2 Connect the 2400 W DC power cables in the following order (Figure 3-34):

a. Ground cable first.

b. Positive cable next.

c. Negative cable last.

d. Repeat Steps a, b, and c for the other PDU.

Warning To prevent injury and damage to the equipment, always attach the ground and source DC power cable lugs to power shelf terminals in the following order: (1) ground to ground, (2) positive (+) to positive (+), (3) negative (-) to negative (-).
