Physical Placement

The Cisco uBR7100 series router can be installed either on a tabletop or in a standard 19- or 23-inch mounting rack. See the following sections for more information:

•Mounting the Chassis on a Tabletop

•Rack-Mounting the Chassis

Mounting the Chassis on a Tabletop

The Cisco uBR7100 series router can be mounted on a flat, hard, and stable surface, such as a tabletop. Ensure that the mounting area has a sufficient footprint to accommodate the router, as given in the "Site Requirement Guidelines" section on page 2-6.

Equipment not located correctly on a tabletop is susceptible to malfunctions and shutdowns, and can make maintenance difficult. Make sure that the equipment is not placed too close together, that the equipment has adequate ventilation, and that all panels are easily accessible.

Before placing the router on the tabletop, attach the rubber feet as shown in Figure 3-1. Rubber feet are included in the accessory kit that shipped with your router.

Figure 3-1 Attaching the Rubber Feet

Warning Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury and equipment damage. Statement 48

Rack-Mounting the Chassis

Tip If you rack-mount the router with the back panel forward, attach the system ground connection before you rack-mount the router. For instructions on how to connect the system ground, see the next section, "Attaching the System Ground Connection."

Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

•This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

•When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

•If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006

Tip If using an external upconverter, it should be mounted either above or below the Cisco uBR7100 series router to minimize the length of cable connecting the downstream port to the upconverter.

This section describes how to rack-mount the chassis in a standard four-post equipment rack. The router is shipped with 19-inch rack-mount brackets; larger brackets for use with a 23- or 24-inch rack are available separately (the product number is ACS-7100-RMK=).

See Figure 3-2 illustrates the rack-mount brackets that are used with the Cisco uBR7100 series routers:

Figure 3-2 Standard Rack-Mount Brackets

Attaching the Brackets

To install the chassis in a rack, attach the brackets in one of the following ways:

•Front panel forward (see Figure 3-3)

•Back panel forward (see Figure 3-4)

Note Although the installations show the 19-inch brackets, the procedure is the same for the 23- and 24-inch brackets.

Figure 3-3 Standard Bracket Installation—Front Panel Forward

Figure 3-4 Standard Bracket Installation—Back Panel Forward

Installing the Chassis in a Rack

After the brackets are secured to the chassis, you can rack-mount the router. Using the screws that you provide, attach the chassis to the rack as shown in Figure 3-5. You need two people to install the chassis in the rack—one person to hold the router and one person to secure it to the rack.

Figure 3-5 Attaching the Chassis to the Rack—Back Panel Forward

Attaching the System Ground Connection

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Before you connect power or turn on power to your router, we strongly recommend that you provide an adequate chassis ground (earth) connection for your router's chassis. This connection is required for a central office that must comply with Telcordia bonding requirements; it is optional but highly recommended for other installations.

Note The Telcordia bonding connections are in addition to the grounding that is required for the AC power connection.

Chassis grounding receptacles for Telcordia bonding connections are provided on each side of the router, near the rear of the chassis.

Note One set of grounding receptacles should be used for the Telcordia bonding ground connection, and the other set can be used for attaching the cable management bracket (see Attaching the Ground Wire).

To ensure that the chassis grounding connection that you provide is adequate, you need the following parts and tools:

•One grounding lug—Must have two 3.5-mm screw holes that have a 0.63-inch (16.002-mm) spacing between them, and a wire receptacle large enough to accept a 6-American Wire Gauge (AWG) multistrand, copper wire. This grounding lug is provided in the accessory kit.

•Two slotted hexhead 3.5 x 7-mm thread-forming machine screws. These screws are provided in the accessory kit.

•One grounding wire—6-AWG, 0.162-inch (4.115-mm) diameter, with approximately 0.108 inch (2.743 mm) of insulation, for a total wire diameter of approximately 0.27 inch (6.858 mm). The wire's length is dependent on your router location and site environment. This wire is not available from Cisco Systems; it is available from any commercial cable vendor.

•Flat-blade screwdriver

•Crimping tool large enough to accommodate the diameter of the wire receptacle on your grounding lug

•Wire stripper

Attaching the Ground Wire

To attach the grounding lug to the chassis grounding receptacles on the router, use the following procedure:

Step 1 Use the wire stripper to strip one end of the 6-AWG wire approximately 0.75 inch (19.05 mm).

Step 2 Insert the 6-AWG wire into the wire receptacle on the grounding lug.

Step 3 Use the crimping tool to carefully crimp the wire receptacle around the wire; this step is required to ensure that a proper mechanical connection.

Step 4 Insert the two screws through the holes in the grounding lug. (See Figure 3-6.) Ensure that the grounding lug does not interfere with other router hardware.

Figure 3-6 Attaching the Ground Wire to the Grounding Lug

Step 5 Locate the chassis grounding receptacles that are on either side on your router chassis. Choose the side that is most convenient for attaching the grounding wire. (See Figure 3-7.)

Figure 3-7 Attaching the Grounding Lug to the Telcordia Bonding Grounding Receptacles

Step 6 Use the flat-blade screwdriver to carefully tighten the screws until the grounding lug is held firmly to the chassis. Do not overtighten the screws.

Step 7 Connect the opposite end of the grounding wire to the appropriate grounding point at your site to ensure an adequate chassis ground.

Attaching the Cable-Management Bracket

To install the cable-management bracket on the router, complete the following steps:

Step 1 Locate the chassis grounding receptacles on the rear sides of the chassis. (See Figure 3-8.)

Note Both rear sides of Cisco uBR7100 series chassis have two grounding receptacles. Attach the cable-management bracket to the two grounding receptacles that were not used to ground the chassis in the "Attaching the System Ground Connection" section.

Step 2 Align the cable-management bracket to the vacant receptacles. Ensure that the two flanges on the bracket are facing away from the chassis.

Step 3 Thread two 3.5 x 7-mm slotted hexhead screws through the bracket and into the chassis. Use a flat-head screwdriver to tighten the screws. Use tie wraps to secure interface cables to the bracket flanges.

Figure 3-8 shows how to attach the cable-management brackets to the Cisco uBR7114 or Cisco uBR7114E chassis; the Cisco uBR7111 or Cisco uBR7111E chassis is identical.

Figure 3-8 Attaching the Cable-Management Bracket to the Chassis (Cisco uBR7114 chassis)

Step 4 As you connect the interface cables, carefully lace each cable through the cable-management bracket as needed.

This completes the steps for installing the cable-management bracket on a Cisco uBR7100 series router.

Connecting to the Network

This section describes how to connect the router to your network. The cables required to connect the router to a network are not provided. For ordering information, contact customer service. For cable product numbers and port pinouts, see Appendix C, "Cable Specifications".

The router has integrated LAN Fast Ethernet ports and arrives with the modular port adapter already installed, unless you order a port adapter separately as a spare. For information on installing port adapters, see the installation and configuration notes for your port adapter.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001

Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first. Statement 1026

Connecting Upstream and Downstream Ports

The upstream and downstream ports are connected as follows:

•DS0 RF outputs the downstream after it has been processed by the Cisco uBR7100 series integrated upconverter. This is an RF signal suitable for output to a combiner.

•DS0 outputs the downstream as an IF signal. This signal must be output into an external waveconverter before sending it to a combiner.

•US connects the upstream cables to the upstream ports. If an upstream port is not being used, it should remain unconnected.

Use high-quality RG-59 cabling for both the upstream and downstream ports. RG-6 cable is not recommended for headend use.

Figure 3-9 Connecting Upstream and Downstream Ports

Connecting the Fast Ethernet Ports

The 10BASE-T/100BASE-TX Fast Ethernet ports support IEEE 802.3 and IEEE 802.3u specifications for 10-Mbps and 100-Mbps transmission over unshielded twisted-pair (UTP) cables. These ports also support autosensing and autonegotiation of the proper transmission mode (half duplex or full duplex) with an attached device.

Each Fast Ethernet port has an RJ-45 connector that supports standard straight-through and crossover Category 3 or Category 5 UTP cable:

•Use Category 3 UTP straight-through cables when connecting a 10BASE-T port to a hub.

•Use Category 3 UTP crossover cables when connecting to a PC or other Ethernet device.

•Use Category 5 UTP straight-through cables when connecting 100BASE-TX to a hub.

•Use Category 5 UTP crossover cables when connecting to a PC or other Ethernet device.

Note Cisco Systems does not supply Category 3 or Category 5 UTP RJ-45 cables; these cables are available commercially. For more information, see the "Fast Ethernet Port Cables and Pinouts" section on page C-4.

To connect the Fast Ethernet port to an Ethernet hub, use the following procedure:

Step 1 Verify that the Ethernet hub is properly connected to the rest of the LAN.

Step 2 Attach the appropriate cable directly to the receptacle on the router. (See Figure 3-10.)

Step 3 Attach the network end of the cable to the Ethernet hub or end station. (See Figure 3-10.)

Figure 3-10 Connecting the LAN Port to an Ethernet Hub

Connecting the Console Port and Auxiliary Port

The router arrives with a console and auxiliary cable kit, which contains the cable and adapters you need to connect a console (an ASCII terminal or PC running terminal emulation software) or modem to the router. The console and auxiliary cable kit includes:

•RJ-45-to-RJ-45 rollover cable

•RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL)

•RJ-45-to-DB-25 male DCE adapter (labeled MODEM)

Note For more information, see the "Console and Auxiliary Port Cables and Pinouts" section on page C-2.

Connecting to the Console Port

Use the console terminal for local administrative access to the router. You can connect a terminal to the console port only.

To connect the console port to a terminal (an ASCII terminal or a PC running terminal emulation software), use the following procedure:

Step 1 Connect one end of the RJ-45 rollover cable to the RJ-45-to-DB-9 adapter (labeled TERMINAL).

Step 2 Connect the other end of the rollover cable directly to the console port on the router. (See Figure 3-11.)

Figure 3-11 Connecting the Console Terminal

Step 3 Attach the DB-9 connector to the appropriate serial connector on the PC or terminal. (See Figure 3-11.)

Step 4 Configure the terminal or PC terminal emulation software for 9600 baud, 8 data bits, no parity, 2 stop bits, and no flow control.

Note Do not set the terminal emulation software for either hardware or software flow control. Doing so will prevent communications with the router.

Connecting a Modem to the Auxiliary Port

You can use the auxiliary port to connect a terminal or a modem for remote access to the router.

Note For more information about the console port and auxiliary port connectors, see the "Console and Auxiliary Port Cables and Pinouts" section on page C-2.

To connect the auxiliary port to a modem, use the following procedure:

Step 1 Connect one end of the RJ-45 rollover cable to the RJ-45-to-DB-25 adapter (labeled MODEM).

Step 2 Connect the other end of the rollover cable directly to the auxiliary port on the router. (See Figure 3-12.)

Figure 3-12 Connecting a Modem to the Auxiliary Port

Step 3 Attach the DB-25 connector to the modem. (See Figure 3-12.)

Step 4 Make sure that the modem and the auxiliary port on the router are configured for the same transmission speed (38.4 Kbps and 56 Kbps are typical). Configure the modem for auto-answer, and for hardware flow control using the Data Carrier Detect (DCD) and Data Terminal Ready (DTR) signals.

Connecting the Power

Cisco uBR7100 series routers feature four-output switching AC power supplies that provide power factor correction and regulated outputs. Cisco uBR7100 series routers have one AC-input power supply.

Note For information on the power supply specifications, see Appendix A, "System Specifications".

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. Statement 4

Check the following conditions before you start the router:

•The port adapter is securely inserted in its slot.

•All network interface cables are connected.

•A flash disk or flash memory card is installed in its PC Card slot.

•The console terminal is connected and powered on.

To connect the AC power on Cisco uBR7100 series routers, use the following procedure:

Step 1 At the back of the router, check that the power switch is in the OFF (O) position.

Step 2 Connect one end of the power cord to the power connector on the back of the router. (See Figure 3-13.)

Step 3 Connect the other end of the power cord to the power outlet.
