Chassis Installation Procedures for Cisco 1800 Series Routers (Modular)

This document tells how to physically set up Cisco 1800 series integrated services routers (modular). It contains the following sections:

•Setting Up the Chassis

•Installing the Chassis Ground Connection

Cisco 1800 series routers are normally shipped with a complement of components that can be upgraded or replaced to expand and enhance the router's functionality. These components either are inserted internally into the router or are plugged into slots in the router chassis.

Note To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information for Cisco 1840 Routers document that accompanies your router.

Internal Components

The router's internal components include the following:

•SDRAM

•Advanced integration module (AIM)

If you need to remove or upgrade either of these items, follow the procedures given in the "Installing and Upgrading Internal Modules in Cisco 1800 Series Routers (Modular)" document.

Plug-In Components

The following components plug into the router chassis:

•WAN interface cards (WICs)

•Voice/WAN interface cards (VWICs), data mode only

•High-speed WICs (HWICs)

•CompactFlash memory card

If you need to remove or install WICs, VWICs, or HWICs, follow the procedures in the "Installing Interface Cards in Cisco 1800 Series Routers (Modular)" document.

If you need to remove or upgrade the CompactFlash memory card, follow the procedure in the "Installing and Replacing CompactFlash Memory Cards on Cisco 1800 Series Routers (Modular)" document.

Setting Up the Chassis

The Cisco 1841 router can be installed on a desktop, and can also be mounted on a wall. Select the setup that best meets the needs of your network. These setups are described in the following sections:

•Setting the Chassis on a Desktop

•Rack-Mounting a Cisco 1800 Series Modular-Configuration Router

•Wall-Mounting the Chassis

Caution The front panel bezel must not be removed from the Cisco 1841 router. It is part of the product's enclosure, and must be left in place to prevent damage from foreign parts entering the router, to provide a shield from internal electromagnetic interference (EMI), and to direct the flow of cooling air properly through the chassis.

Setting the Chassis on a Desktop

You can place Cisco 1841 routers on a desktop or shelf. The Cisco 1841 router is shipped with the rubber feet attached to the chassis to provide space for air circulation.

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 kilograms). Excessive weight on top of the router could damage the chassis.

Rack-Mounting a Cisco 1800 Series Modular-Configuration Router

If you are planning to rack-mount the router, rack-mount it before you make the network and power connections. If you need to install any internal modules, such as an expansion DIMM or an inline power supply card, install these prior to rack-mounting.

To install a Cisco 1800 series modular-configuration router in a 19-inch rack, use the brackets included in the optional rack-mount kit (SKU: ACS-1841-RM-19=).

Note All Cisco 1841 chassis shipping since Q4FY06 are rack-mountable. Cisco 1841 chassis with the following starting serial numbers have the rack-mount screw holes: FTX1009W0Z3 (United States), FCZ100812UR (Europe, Middle East, and Africa), and FHK100653JL (Asia Pacific).

Note Brackets for 23-inch equipment racks are not available for Cisco 1800 series modular-configuration routers.

The brackets are shown in Figure 1.

Figure 1 Rack-Mounting Brackets

Attaching Rack-Mount Brackets

Use four of the supplied number-8 Phillips flat-head screws to attach each bracket to the router. Figure 2 shows how to attach the brackets to the sides of the router with the back panel forward.

Figure 2 Attaching Rack-Mounting Brackets to a Cisco 1800 Series Modular-Configuration Router

Installing the Router in a Rack

After you attach the brackets to the router chassis, use the screws provided with the rack to install the chassis in the rack. (See Figure 3.) Start with 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 Take care when connecting units to the supply circuit so that wiring is not overloaded. Statement 1018

Warning To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 50°C (122°F). Statement 1047

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

Chassis Grounding

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

Wall-Mounting the Chassis

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

The Cisco 1841 router can be wall-mounted by using two number six, 3/4-inch screws and the mounting features on the bottom of the router. You must provide the screws. We recommend using pan-head or round-head screws.

The wall-mounting features on the router are shown in Figure 4.

Wall-mounting features

To mount the router on a wall or other surface, follow these steps:

Step 1 Install the two screws 6.00 inches (15.2 centimeters) horizontally apart on a wall or other vertical surface.

The screws should protrude 0.25 inch (0.6 centimeter) from the surface of the wall.

Step 2 Remove the rubber feet from the router.

Step 3 Hang the router on the screws, front panel down. This is the appropriate orientation for safe use. See Figure 5.

Mounting screws

Caution If you install the screws in drywall, use hollow-wall anchors (1/8 inch by 5/16 inch) to secure the screws. If the screws are not properly anchored, the strain of the cables connected to the router back panel could pull the router from the wall.

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

You must connect the chassis to a reliable earth ground, using a ground lug and size 14 AWG (2 mm²) wire. To install the ground connection for a Cisco 1800 series router, follow these steps:

Step 1 Strip one end of the ground wire to expose approximately 0.75 in. (20 mm) of conductor.

Step 2 Crimp the 14 AWG green ground wire to a UL Listed/CSA certified ring terminal that is suitably sized for the number 6 ground screw provided on the rear panel of the router. The crimping tool should be one that is recommended by the ring lug terminal manufacturer.

Step 3 Attach the ring terminal to the chassis. The attachment points for the Cisco 1841 router are shown in Figure 6. Use a number 2 Phillips screwdriver and the screw supplied with the ground lug. Tighten the screw to a torque of 8 to 10 in-lb. (0.9 to 1.1 N-m).
