Chapter 3 Installing the Router

Installing the Chassis in a Rack

This section explains how to install Cisco 12006 and Cisco 12406 Routers in a rack. This procedure assumes you have unpacked the router using the Cisco 12006 and Cisco 12406 Router Unpacking and Repacking Instructions (Document number 78-16104-xx) posted on the outside of the shipping container.

You mount the chassis in the equipment rack by setting the chassis in position against the rack rails and then securing it to the rack or optional center-mount brackets with screws through holes in the rack-mounting flanges on either side of the chassis. To accommodate racks with different hole patterns in their rails, the chassis rack-mounting flanges have two groups of eight oblong screw holes on either side. (See Figure 3-3.) The mounting holes in the chassis flanges are spaced so that one mounting hole in each hole group aligns with a hole in the rack rail or optional center-mount bracket. By using the corresponding mounting hole (in the same hole group) on the opposite side of the chassis, you can level the chassis in the rack.

Chapter 3 Installing the Router

Supplemental Bonding and Grounding Connections

Installing the Chassis on a Tabletop or Flat Surface

Follow the steps below to install a Cisco 12006 Router or Cisco 12406 Router on a tabletop or stable flat surface. You can use the same mounting hardware that secured your router to the shipping pallet to secure the chassis to a flat surface.

Step 1 Move the router as close to the installation location as possible.

Caution Do not lift the chassis by the blower module handle. This handle is designed to

support only the weight of the blower module.

Step 2 With one person positioned at the front of the chassis and one at the rear, lift the

chassis off the pallet and position the chassis on the flat surface.

Step 3 Secure the chassis to the flat surface to ensure that it does not fall off.

Supplemental Bonding and Grounding Connections

If the router is installed in a network equipment building system (NEBS) environment, follow the guidelines in this section. For installations other than in a NEBS environment, you may chose to rely on the safety earth ground connection supplied via the International Electrotechnical Commission (IEC) 320 inlets for AC-powered units and the main terminal block ground connection for DC-powered units.

Even though the router chassis requires a safety earth ground connection as part of the power cabling to the PDU, we strongly recommend that you connect the central office ground system or interior equipment grounding system to the supplemental bonding and grounding receptacle on the router chassis, which satisfies the Telcordia NEBS requirement for supplemental bonding and grounding connections. This receptacle consists of three threaded inserts located on the side of the chassis near the back panel. (See Figure 3-4.)

Chapter 3 Installing the Router

Caution Carefully adjust the cable in the cable-management brackets to prevent any kinks

or sharp bends in the interface cable. Kinks and sharp bends 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. Also, allow adequate strain relief in the interface cable.

Step 6 Route the cable through the fingers on the vertical chassis cable-management

bracket and turn the latch on the front of the bracket to secure the cables in the bracket.

Connecting Alarm Card Cables

Cisco 12006 and Cisco 12406 Routers have two alarm cards located in the two slots immediately above the left power supply bay and directly below the clock and scheduler card slots. Each alarm card is equipped with a standard DB-9 connector, labeled ALARM. This connector can be used to connect the router to an external site alarm maintenance system so that any critical, major, and minor alarms generated in the router also energize alarm relays on the alarm card and activate the external site alarm. Appendix A, “Technical Specifications,” 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 Systems.

Connecting Alarm Card Cables

OL-11497-03

Note Only safety extra-low voltage (SELV) circuits can be connected to the alarm

connector. Maximum rating for the alarm circuit is 2A, 50VA.

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 to the Console and Auxiliary Ports

This section provides the information for connecting console terminals and other auxiliary devices to the console and auxiliary ports on the router. Both Data Set Ready (DSR) and Data Carrier Detect (DCD) signals are active when the system is running. The console port does not support modem control or hardware flow control. GRP ports are discussed below. PRP ports are discussed in the “PRP

Console and Auxiliary Ports” section on page 3-18.

GRP Console and Auxiliary Ports

This section provides connection equipment and pin designation information for the console and auxiliary ports on the Gigabit Route Processor (GRP).

Note To maintain Class B, EMI compliance, shielded cables must be used on the

console and auxiliary ports of the GRP= and GRP-B=.

3-14

The GRP has two EIA/TIA-232 ports:

• DCE DB-25 receptacle for connecting a console terminal

• DTE DB-25 plug for connecting other DTE devices

The DCE-mode console port is a DCE DB-25 receptacle used for connecting a console terminal, which you will need to configure the router.

The DTE-mode auxiliary port is a 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 the router.

Note The console and auxiliary ports are asynchronous serial ports; any devices

connected to these ports must be capable of asynchronous transmission. Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.

• RJ-45 receptacle—An 8-pin media-dependent interface (MDI) RJ-45

receptacle for either an IEEE 802.3 10BASE-T (10 Mbps) or an IEEE 802.3u 100BASE-TX (100 Mbps) connection.

• MII receptacle—A 40-pin media independent interface (MII) receptacle that

provides additional flexibility in Ethernet connections. This connector can also be used for either an IEEE 802.3 10BASE-T (10 Mbps) or an IEEE 802.3u 100BASE-TX (100 Mbps) connection.

Chapter 3 Installing the Router

Note The RJ-45 and MII receptacles on the GRP represent two physical connection

options for one Ethernet interface; you can use either the MDI RJ-45 connection or the MII connection, but not both simultaneously. The transmission speed of the Ethernet port is set through an auto-sensing scheme on the GRP. The speed is determined by the network to which the Ethernet interface is connected, and is not user-configurable. Moreover, even at the auto-sensed data transmission rate of 100 Mbps, the Ethernet port provides maximum usable bandwidth of less than 100 Mbps. Expect a maximum usable bandwidth of approximately 20 Mbps when using either the MII or RJ-45 connection.

The Ethernet port can use either unshielded twisted-pair or screened twisted-pair cable. In sites where extremely high immunity to noise is required, screened twisted-pair cable is recommended. Figure 3-12 shows the layout of the Ethernet MII receptacle on the GRP.

The PRP includes two 10/100 Mbps Ethernet ports, each using an 8-pin RJ-45 receptacle for either IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps) connections. The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable.

The Ethernet interfaces on the PRP are end-station devices, not repeaters; therefore, you must connect an Ethernet interface to a repeater or hub. 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.

RJ-45 cables are not available from Cisco Systems, but are available from outside commercial cable vendors.

Connecting to the Console and Auxiliary Ports

Note Use cables that comply with EIA/TIA-568 standards. (See Table 3-8 on page 3-29

and Table 3-9 on page 3-29 for cable recommendations and specifications.)

Caution The Ethernet ports are used primarily as Telnet ports into the 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. Cisco strongly cautions you to consider the security implications of switching on CEF routing functions on these ports.

Figure 3-14 shows an example of the functionality of an Ethernet port. In this

example, you cannot access Network 2.0.0.0 via the Ethernet port (ETH0) on the PRP in Router A; you can only access the hosts and Router C, which are in Network 1.0.0.0. (See dotted arrows in Figure 3-14.)

To access Network 2.0.0.0 from Router A, use an interface port on one of the line cards (in this example, a Packet-over-SONET [POS] line card in Router A) to go through Router B, through Router C, and into Network 2.0.0.0. (See solid arrows in Figure 3-14.)
