Setting Up the Chassis

The Cisco 1841 router and the Cisco 1861 ISR 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 objects 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.

To install a chassis on a desktop, table, or other flat surface, place the unit upside-down on a flat surface. Attach the four rubber pads to the recessed areas on the bottom of the unit. Place the unit on a desktop.


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 lbs (4.5 kg). Excessive weight on top of the router could damage the chassis.


Caution The Cisco 1861 Integrated Services Router installation must allow unrestricted airflow for cooling. For placing the platform on a desktop, keep at least 1 in. (2.54 cm) of clear space beside the cooling inlet and exhaust vents.

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.


Note 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=).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.


Figure 4-1 shows the brackets.

Figure 4-1 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 4-2 shows how to attach the brackets to the sides of the router with the back panel forward.

Figure 4-2 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 4-3.) 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.
