Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. Statement 1 Warning Read the installation instructions before connecting the system to the power source. Statement 1004 Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security.
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.
Rack-Mounting the Router Cisco 2811, Cisco 2821, and Cisco 2851 routers can be installed in 19- and 23-inch (48.26-cm and 58.42-cm) racks. Cisco 2801 routers can be installed only in 19-inch racks, and cannot be center mounted. Use the standard brackets for mounting the chassis in a 19-inch rack;...

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 7 Bracket Installation for Front Mounting AUX / COM PAC T FLA SH...
Page 15
On rack-mount brackets for Cisco 2821 and Cisco 2851 routers, you can attach the cable management bracket to either the upper or the lower threaded hole. See Figure 10 and Figure 11 for cable management bracket attachment locations.

Either edge may go up. Attach to either side of the chassis. Wall-Mounting the Router—Cisco 2811 Routers Only You can mount a Cisco 2811 router on a wall. Cisco 2801, Cisco 2821, and Cisco 2851 routers are not designed for wall-mounting. Warning This unit is intended to be mounted on a wall.
Caution hazard. Installing the Router on a Desktop If you install your Cisco 2800 series router on a desktop, observe the following precautions: For Cisco 2801 routers, attach the four rubber feet to the bottom of the chassis. Note Caution Your chassis installation must allow unrestricted airflow for chassis cooling.

• Connecting the Router to AC Power, page 20 • Connecting the Router to DC Power, page 21 • Connecting the Router to Backup Power, page 26 Cisco 2801 routers are not designed to connect to DC power. Note Warning Read the installation instructions before connecting the system to the power source.
Note The DC-input power supply does not apply to Cisco 2801 router. A Cisco 2800 series integrated services router with a DC-input power supply requires copper wire for the power connections. Table 1 and Table 2 summarize the wiring requirements.

A input and one source to the B input. Both sources must be the same polarity (with respect to ground) and voltage (within 0.25 volts). Do not connect –DC grounded and +DC grounded dual sources to Cisco 2811, Cisco 2821, and Cisco 2851 series integrated services routers.
Page 25
When source A and source B are wired with common negative terminals, as in Figure 22, discharging does not occur Note and there is no restriction requiring that source A and source B voltages be equal. Figure 23 Connecting Source A and Source B with Common Positive Terminals Va voltage = Vb voltage (greater than 0.25 V) Va voltage = Vb voltage (within 0.25 V) In Figure 24, source A and source B are wired with opposite polarity grounds.
The RPS is not supported on Cisco 2801 routers.

Caution Checklist for Power-Up You are ready to power up the Cisco 2800 series integrated services router after the following steps are completed: • Chassis is securely mounted and grounded. (See the “Install Chassis” section on page 6.) • Power and interface cables are connected. (See the “Connect Cables” section on page 19.) •...
Power-Up Procedure To power up your Cisco 2800 series router and verify that it goes through its initialization and self-test, perform this procedure. When the procedure is finished, the Cisco 2800 series router is ready to configure. To view the boot sequence, you must have a console connection to the Cisco 2800 series router before it powers up.
On the Cisco 2801 router, the numbering format for slots is interface type 0/slot/port. “0” indicates slots that are built into the chassis of a router. On the Cisco 2801 router, all slots begin with “0,” because all slots are built into the chassis.
Page 31
1. A VWIC in slots 1, 2, and 3 can operate in both data and voice mode; in slot 0, a VWIC can operate only in voice mode. Note On the Cisco 2801 router, the numbering format for configuring an asynchronous interface is 0/slot/port To configure the line associated with an asynchronous interface, simply use the interface number to specify the asynchronous line.
3. Interface card slot numbers for double (HWIC-D) slots are 1 and 3 only. 4. Specify the line number in the Cisco IOS CLI by using the interface number for the associated asynchronous serial interface. 5. “1” is the network module slot number in all Cisco 2800 series routers.
The setup command facility prompts you for basic information about your router and network, and it creates an initial configuration file. After the configuration file is created, you can use the CLI or Cisco Router and Security Device Manager (SDM) to perform additional configuration.

If these messages do not appear, SDM and a default configuration file were installed on the router at the factory. To use SDM to configure the router, see the “Initial Configuration Using Cisco Router and Security Device Manager (SDM)” section on page 32.
• To verify that you configured the correct hostname and password, enter the show configuration command. When you complete and verify the initial configuration, your Cisco router is ready to configure for specific functions. See the “Where to Go Next” section on page 36 for information about locating documentation for advanced configuration procedures.
