Note If there are internal FRUs to be removed or installed, perform the installation or removal before you install the chassis in a rack on a wall. To remove internal FRUs, you have to remove the chassis cover; this requires removal of the chassis from the rack.


If the required internal FRUs are already installed, proceed to the next section, "Setting Up the Chassis".

Setting Up the Chassis


Note Cisco 2800 series routers are normally ordered with modules and interface cards preinstalled. Before you remove or install any modules or interface cards, see the documents that accompany those items or to the online Cisco 2800 series hardware installation documentation at the following URL:

http://www.cisco.com/en/US/docs/routers/access/2800/hardware/installation/guide/hw.html

For module and interface card compatibility information, see the data sheet for each module and interface card.



Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. Statement 1

You can set any Cisco 2800 series router on a desktop or install it in a rack. A Cisco 2811 router can also be mounted on a wall or other flat surface. See the applicable instructions in the following sections.

Rack-Mounting the Chassis

Setting the Chassis on a Desktop

Mounting a Cisco 2811 Router on a Wall


Caution To prevent damage to the chassis, never attempt to lift or tilt the chassis by the plastic panel on the front. Always hold the chassis by the metal body.

Rack-Mounting the Chassis

If you are planning to rack-mount the router, do so before making network and power connections. If you need to install network modules or interface cards, you can do so either before or after rack-mounting the router. Ideally, you would install modules and interface cards when you have the best access to the rear panel of the router. Internal modules, such as advanced integration modules (AIMs) or packet voice data modules (PVDMs), should be installed prior to rack-mounting.

Cisco 2811, Cisco 2821, and Cisco 2851 routers can be installed in 19 (48.26-cm)- and 23-inch (58.42-cm) racks. Cisco 2801 routers can be installed only in 19-inch racks, and cannot be center mounted. Use the standard brackets shipped with the router for mounting the chassis in a 19-inch rack; you can order optional larger brackets for mounting the chassis in a 23-inch rack.


Note Brackets for 23-inch (58.42-cm) equipment racks are not available for Cisco 2801 routers.


You can mount the router in the following ways:

Center mounting—Brackets attached in the center of the chassis with only the front panel facing forward. (This option is not available on Cisco 2801 routers.)

Front mounting—Brackets attached at the front of the chassis with the front panel facing forward.

Rear mounting—Brackets attached at the rear of the chassis with the rear panel facing forward.

The brackets are shown in Figure 5, Figure 6, and Figure 7.

Figure 5 Rack-Mounting Brackets for Cisco 2801 Routers for 19-Inch Rack

Figure 6 Rack-Mounting Brackets for Cisco 2811 Routers

Figure 7 Rack-Mounting Brackets for Cisco 2821 and Cisco 2851 Routers

Attaching Rack-Mount Brackets to Cisco 2801 Routers

Use four of the supplied number-8 Phillips flat-head screws to attach the long side of each bracket to the router. Figure 8 shows how to attach the brackets to the sides of the router with the front panel forward.

Figure 8 Attaching Rack-Mounting Brackets to a Cisco 2801 Router

Attaching Rack-Mount Brackets to Cisco 2811, Cisco 2821, and Cisco 2851 Routers

Attach the mounting brackets to the router chassis as shown in Figure 9 through Figure 11, using the screws provided.


Caution Do not overtorque the screws. The recommended torque is 15-18 inch-lb (1.7-2.0 N-m).

Attach the second bracket to the opposite side of the chassis. Use a number 2 Phillips screwdriver to install the bracket screws.


Caution Your chassis installation must allow unrestricted airflow for chassis cooling.

Figure 10 Bracket Installation for Rear Mounting

Figure 11 Bracket Installation for Center Mounting with Front Panel Forward

Installing the Router in a Rack

After you have attached the brackets to the router chassis, use the screws provided with the rack to install the chassis in the rack. (See Figure 12.)


Tip Start the lower pair of screws first, and rest the brackets on the lower screws while you insert the upper pair of screws.



Tip The screw slots in the brackets are spaced to line up with every second pair of screw holes in the rack. When the correct screw holes are used, the small threaded holes in the brackets line up with unused screw holes in the rack. If the small holes do not line up with the rack holes, you must raise or lower the brackets to the next rack hole.



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

 




Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit. Statement 1032

Caution Be sure to leave space above and below each router in a rack, to allow for cooling air circulation.

Figure 12 Mounting the Chassis in a Rack (Typical)

Attaching Optional Cable Management Bracket

The optional cable management bracket provides attachment points for organizing and routing cables. On brackets for the Cisco 2801 and Cisco 2811 routers, attach the cable management bracket to the left or right rack-mount bracket using the screw provided, as shown in Figure 13 and Figure 14. On brackets for 2-rack-unit-high Cisco 2821 and Cisco 2851 routers, you can attach the cable management bracket to either the upper or lower threaded hole on either the left or right rack-mount brackets using the
screw provided.

Chassis Grounding

After the router is installed, you must connect the chassis to a reliable earth ground. For the chassis ground connection procedures, see the "Installing the Chassis Ground Connection" section.

Setting the Chassis on a Desktop

You can place Cisco 2800 series routers on a desktop or shelf. If you are placing a Cisco 2801 router on a desktop, you must first install the four rubber feet that are supplied in the accessory kit. They provide space for air circulation and antiskid protection. Peel the rubber feet from the adhesive strip, and stick them onto the features marked "+" on the bottom of the chassis.


Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit. Statement 1032

Caution Do not place anything on top of the router that weighs more than 10 pounds (4.5 kg), and do not stack routers on a desktop. Excessive distributed weight of more than 10 pounds, or pound point load of
10 pounds on top could damage the chassis.


Caution Your chassis installation must allow unrestricted airflow for chassis cooling. For placing the router on a desktop, keep at least 1 inch (2.54 cm) of clear space beside the cooling inlet and exhaust vents.

After the router is installed, you must connect the chassis to a reliable earth ground. For the chassis ground connection procedures, see the "Installing the Chassis Ground Connection" section.

Mounting a Cisco 2811 Router on a Wall

This section explains how to mount Cisco 2811 routers on a wall or other vertical surface. Mounting Cisco 2801, Cisco 2821, and Cisco 2851 routers on a wall is not recommended.

The following warning applies to Cisco 2811 routers:


Warning This unit is intended to be mounted on a wall. Please read the wall mounting instructions carefully before beginning installation. Failure to use the correct hardware or to follow the correct procedures could result in a hazardous situation to people and damage to the system. Statement 248

Tip When choosing a wall mounting location, consider cable limitations and wall structure.


Use brackets designed for 23-inch rack-mounting (shown in Figure 6) to wall-mount the chassis.

Attaching Brackets to the Router for Wall Mounting

Attach the standard brackets to the chassis as shown in Figure 15, using the four screws provided for each bracket.

Figure 15 Attaching the Brackets for Wall-Mounting a Cisco 2811 Router

Attaching the Router to a Wall

Attach the router to the wall using the brackets previously attached and attachment hardware that you provide as follows:

For attaching to a wall stud, each bracket requires two #10 wood screws (round- or pan-head) with #10 washers, or two #10 washer-head screws. The screws must be long enough to penetrate at least 3/4 inch (20 mm) into supporting wood or metal wall stud.

For hollow-wall mounting, each bracket requires two wall anchors with washers. Wall anchors and washers must be size #10.


Caution The router must be mounted with the power connections oriented downward. Failure to do so could present a fire hazard.

Figure 16 shows a typical wall-mounted installation.

Figure 16 Mounting the Chassis on the Wall

After the router is installed, you must connect the chassis to a reliable earth ground. For the chassis ground connection procedures, see the "Installing the Chassis Ground Connection" section.

Installing the Chassis Ground Connection


Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you chould shock yourself. Statement 94

You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance with local electrical safety standards.

For NEBS-compliant grounding, use size 6 AWG (13 mm2) copper wire and the ground lug provided in the accessory kit.


Note NEBS-compliant grounding is not supported on the Cisco 2801 router.


For NEC-compliant grounding, use size 14 AWG (2 mm2) or larger copper wire and an appropriate user-supplied ring terminal with an inner diameter of 1/4 in. (5-7 mm).

For EN/IEC 60950-compliant grounding, use size 18 AWG (1 mm2) or larger copper wire and an appropriate user-supplied ring terminal.

To install the ground connection for a Cisco 2800 series router, perform the following steps:


Step 1 Strip one end of the ground wire to the length required for the ground lug or terminal.

For the NEBS ground lug—approximately 0.75 in. (20 mm)

For user-provided ring terminal—as required

Step 2 Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size.

Step 3 Attach the ground lug or ring terminal to the chassis as shown in Figure 17, Figure 18, Figure 19, Figure 20, or Figure 21. For a ground lug, use the two screws with captive locking washers provided. For a ring terminal, use one of the screws provided. Tighten the screws to a torque of 8 to 10 in-lb (0.9 to 1.1 N-m).

Step 4 Connect the other end of the ground wire to a known reliable earth ground point at your site.
