Rack-Mounting the Chassis

Warning

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 378

Warning

Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the

floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip

over.

Statement 1048

The Cisco 1900 series router can be installed in a 19-inch EIA rack. Mounting brackets allow installing

in either a front and rear facing position.

You can mount the router in the following ways:

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

• Back mounting—Brackets attached at the back of the chassis with the back panel facing forward.

Note The rubber feet need to be removed for rack mounting.

Attaching Rack-Mount Brackets to Cisco 1900 Series Routers

Use four of the supplied number-8 Phillips screws to attach the long side of each bracket to the router.

Figure 4-5 shows how to attach the brackets to the sides of the router with the front panel forward.

Torque the screws to 15 to 18 in-lb (1.7 to 2.0 N-m).

Depending on your router model and if you decide to front mount or back mount, attach the brackets

according to one of the following figures:

ISRs

• Figure 4-6 on page 4-8, Bracket Installation for Back Mounting the Cisco 1905 and Cisco 1921 ISRs
