Wiring Procedure for DC Input

To connect the router to a DC power source, perform the following steps:


Step 1 Remove power from the DC circuit. To ensure that power is removed from the DC circuit, locate the circuit breaker for the DC circuit, switch the circuit breaker to the OFF position, and tape the circuit-breaker switch in the OFF position.


Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003



Tip Secure all power cabling when installing this unit to avoid disturbing field-wiring connections.



Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor. Statement 1002


Step 2 Strip the wires to the appropriate length for the terminals. The strip length is 3/16 to 1/4 inch (5 to 6 mm) for Amp number 32957 terminals.

Step 3 Crimp the terminals onto the DC power input and safety ground wires.

Step 4 Remove the plastic covers from the terminal block. Save the covers for reinstallation after you finish wiring.

Step 5 Connect the wires to the terminal block, starting with the safety ground wire. Connect each wire to the appropriate terminal as shown in Figure 18. Tighten the terminal screws to 8.0 ± 0.5 in-lb (0.9 ± 0.05 N-m).


Warning The illustration shows the DC power supply terminal block. Wire the DC power supply as illustrated. The proper wiring sequence is ground to ground, positive to positive, and negative to negative. The ground wire should always be connected first and disconnected last. Statement 239



Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power source wire extends from the terminal block plug. Statement 122



Caution Do not overtorque the terminal block screws. The recommended torque is 8.0 ± 0.5 in-lb (0.90 ± 0.05 N-m).

Figure 18 DC Power Connections for Cisco 2800 Series Routers (Typical)

Step 6 Install the plastic covers over the terminals. (See Figure 19 or Figure 20.)


Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover installed. Operating the unit without the cover in place will invalidate the safety approvals and pose a risk of fire and electrical hazards. Statement 117


Step 7 Organize and secure the wires using cable ties as shown in Figure 19 or Figure 20. Make sure that the wires do not project above or below the front panel of the router.

Step 8 Turn on power to the DC circuit. Be sure to remove tape used to secure the circuit-breaker switch in the OFF position.

Figure 20 DC Wire Routing and Attachment for Cisco 2821 and Cisco 2851 Routers


Approved Scenarios and Scenarios Not Approved for Dual DC Power Supply Configuration

You can connect a single DC power source to either the A input or the B input. If there are dual power sources, connect one source to the 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.


Caution Dual sources with opposite-polarity grounding damage equipment.

In Figure 21, either the positive source terminal or the negative source terminal is tied to ground.

Figure 21 Connecting to One Source Only—Source A or Source B

In Figure 22, source A and source B share common negative terminal connections.

Figure 22 Connecting Source A and Source B with Common Negative Terminals

In Figure 23, source A and source B share common positive terminal connections. This is allowed only if Va equals Vb (within 0.25 V).


Caution When connecting source A and source B with common positive terminals, if source A and source B voltages are unequal by more than 0.25 V, the higher-voltage source can discharge into the lower-voltage source through the A- and B- input terminals. Excessive discharging currents through these terminals can cause one or both of the dual input DC power supply's internal A- or B- fuses to open, resulting in lack of redundancy or system failure. When source A and source B are within 0.25 V, discharge current is minimal.


Note When source A and source B are wired with common negative terminals, as in Figure 22, discharging does not occur 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

In Figure 24, source A and source B are wired with opposite polarity grounds. Do not use this configuration.


Caution Do not use the DC input configuration shown in Figure 24.

Figure 24 Source A and Source B Wired with Opposite-Polarity Grounds

Connecting the Router to Backup Power

If your router uses the Cisco Redundant Power System (RPS), see the Cisco RPS-675 Hardware Installation Guide for instructions about the power connections. To locate this document, see the "Where to Go Next" section.


Caution Before connecting the RPS to the router, make sure that either the RPS is in standby mode or the RPS AC power is disconnected. Connecting the RPS to AC power automatically places the RPS in active mode.


Note The RPS is not supported on Cisco 2801 routers.


WAN, LAN, and Voice Connections

6 Power Up the Router


Caution To ensure adequate cooling, never operate the router unless the cover and all modules and cover plates are installed.

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.)

Power and interface cables are connected. (See the "Connect Cables" section.)

Make sure that the external CompactFlash memory card is properly seated into the slot. For installation instructions, see the online Cisco 2800 series hardware installation documentation at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/2800/hw/index.htm

PC with terminal emulation program is connected to the console port, powered up, and configured for 9600 baud, 8 data bits, 1 stop bit, no flow control, and no parity. (See the "System Management Connections" section.)

Suitable PC COM port is selected in the terminal emulation program.


Note For initial power-up, a direct console connection is recommended. After the initial configuration is completed, a remote modem connection can be used for router management.



Caution To ensure adequate cooling, never operate the router unless the cover and all modules and cover plates are installed.


Caution To prevent damage to the ejector mechanism, the ejector button next to the CompactFlash card must remain fully seated when not being used to eject a CompactFlash card.

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.


Note To view the boot sequence, you must have a console connection to the Cisco 2800 series router before it powers up.



Step 1 Make sure that your PC is powered up and connected as described in the "Checklist for Power-Up" section.

Step 2 Move the power switch to the ON position. The SYS PWR LED on the front of the chassis blinks green and the fans operate. If this does not happen, see the "Troubleshooting" module in the online Cisco 2800 series hardware installation documentation at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/2800/hw/index.htm

Startup messages appear in your terminal emulation program window. When the startup messages end, the SYS PWR LED comes on solid green.


Caution Do not press any keys on the keyboard until the messages stop and the SYS PWR LED is solid green. Any keys pressed during this time are interpreted as the first command typed when the messages stop, which might cause the router to power off and start over. It takes a few minutes for the messages to stop.

You may see different startup messages:

If you see the following messages, the router has booted with a configuration file and is ready for initial configuration using Cisco Router and Security Device Manager (SDM):

yourname con0 is now available

Press RETURN to get started.


Note Because SDM is installed on your router by default, we recommend using SDM to perform the initial configuration.


See the "Initial Configuration Using Cisco Router and Security Device Manager (SDM)" section to learn how to configure your router using SDM, or how to obtain SDM and install it on your router.

If you see the following messages, the router has booted and is ready for initial configuration using the setup command facility or the command-line interface (CLI):

7 Interface Numbering

Table 6 summarizes the interface numbering on a Cisco 2801 series router. Table 7 summarizes the interface numbering on Cisco 2811, Cisco 2821, and Cisco 2851 series routers.


Note The interface numbering on Cisco 2800 series routers is different from the numbering on Cisco 2600 series routers.



Note 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. Note that this is different from the Cisco 2811, Cisco 2821, and Cisco 2851 routers. On these routers, some slots are built into the chassis and have slot numbers that begin with "0." However, it is possible to have other slots that are part of a network module or an extension voice module. Those slots have slot numbers that begin with "1" or "2," respectively.


Table 6 Interface Numbering on Cisco 2801 Series Routers 

Slot Number
Slot Type
Interface Numbering Range

0/3/0 to 0/3/8 (double-wide HWIC)

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.


1 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. For example, line 0/1/0 specifies the line associated with interface serial 0/1/0 on a WIC-2A/S in slot 1. Similarly, line 0/2/1 specifies the line associated with interface async 0/2/1 on a WIC-2AM in slot 2.

Port numbers are 0 to 7 if two expansion modules are installed.

interface bri 2/x

1 Interface abbreviations: fa = Fast Ethernet; gi = Gigabit Ethernet; usb = Universal Serial Bus; bri = ISDN basic rate interface.

2 The interfaces listed are examples only; other possible interface types are not listed.

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.

6 "2" is the EVM slot number in Cisco 2821 and Cisco 2851 routers.

7 "0" is required by the CLI syntax for voice ports in an EVM; it indicates no interface card slots in EVMs.



Note On the Cisco 2811, Cisco 2821, and Cisco 2851 routers, the interface numbering scheme is the same for asynchronous interfaces as other types of interfaces. To configure the line associated with an async interface, simply use the interface number to specify the async line. For example, line 0/3/0 specifies the line associated with interface serial 0/3/0 on a WIC-2A/S in slot 3. Similarly, line 1/22 specifies the line associated with interface async 1/22 on an NM-32A in network module slot 1.


8 Perform Initial Configuration

You can configure your router by using one of the following tools:

Cisco Router and Security Device Manager (SDM)—See the "Initial Configuration Using Cisco Router and Security Device Manager (SDM)" section.

Setup command facility—See the "Initial Configuration Using the Setup Command Facility" section.

Command-line interface (CLI)—See the "Initial Configuration Using the Cisco CLI—Manual Configuration" section.


Note If you need help with the interface and port numbering, see the "Interface Numbering" section.

If the following messages appear at the end of the startup sequence, Cisco Router and Security Device Manager (SDM) is installed on your router:

yourname con0 is now available

Press RETURN to get started.

For instructions on configuring your router by using SDM, see the Cisco Router and Security Device Manager (SDM) Quick Start Guide that shipped with your router.


Tip If the messages above do not appear, SDM and the Cisco Router and Security Device Manager (SDM) Quick Start Guide were not shipped with your router. If you want to use SDM, you can download the latest version of SDM and instructions for installing it on your router from the following location:

http://www.cisco.com/pcgi-bin/tablebuild.pl/sdm

To obtain the SDM quick start guide, SDM release notes, and other SDM documentation, go to www.cisco.com/go/sdm and click the Technical Support and Documentation link.


Initial Configuration Using the Setup Command Facility

This section shows how to use the setup command facility to configure a hostname for the router, set passwords, and configure an interface for communication with the management network. If the following messages appear at the end of the startup sequence, the setup command facility has been invoked automatically:

--- System Configuration Dialog ---

At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.

Would you like to enter the initial configuration dialog? [yes/no]:

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.

The prompts in the setup command facility vary depending on your router model, the installed interface modules, and the software image. The following example and the user entries (in bold) are shown as examples only.

For help with interface and port numbering, see the "Interface Numbering" section.


Note If you make a mistake while using the setup command facility, you can exit and run the setup command facility again. Press Ctrl-C, and type setup at the privileged EXEC mode prompt (Router#).



Step 1 To proceed using the setup command facility, enter yes when the power-up messages have ended.

This section shows how to display a command-line interface (CLI) prompt for configuration using the CLI, and it directs you to documentation for the CLI configuration. You can use the CLI if the following messages appear at the end of the startup sequence:

--- System Configuration Dialog ---

At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.

Would you like to enter the initial configuration dialog? [yes/no]:

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.

For help with interface and port numbering, see the "Interface Numbering" section.


Step 1 To proceed with manual configuration using the CLI, enter no when the power-up messages end:

Would you like to enter the initial configuration dialog? [yes/no]: no

Step 2 Press Return to terminate autoinstall and continue with manual configuration:

Would you like to terminate autoinstall? [yes] Return

Several messages appear, ending with a line similar to the following:

...
Copyright (c) 1986-2004 by cisco Systems, Inc.
Compiled <date> <time> by <person>

Step 3 Press Return to display the Router> prompt.

...
flashfs[4]: Initialization complete.
Router>

Step 4 Enter privileged EXEC mode:

Router> enable 
Router#

Step 5 For configuration procedures, see the applicable configuration instructions in the Cisco 2800 series software configuration documents. See the "Where to Go Next" section for information about accessing these documents.


Note To avoid losing work you have completed, be sure to save your configuration occasionally as you proceed. Use the copy running-config startup-config command to save the configuration to NVRAM.


Step 6 When you have finished the initial configuration, verify the initial configuration. See the "Verify the Initial Configuration" section for verification procedures.


Verify the Initial Configuration

Verify that the new interfaces are operating correctly by performing the following tests:

To verify that the interfaces are operating correctly and that the interfaces and line protocol are in the correct state—up or down—enter the show interfaces command.

To display a summary status of the interfaces configured for IP, enter the show ip interface brief command.

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 for information about locating documentation for advanced configuration procedures.

http://www.cisco.com/en/US/products/products_psirt_rss_feed.html

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you might have identified a vulnerability in a Cisco product, contact PSIRT:

Emergencies — security-alert@cisco.com

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

Nonemergencies — psirt@cisco.com

In an emergency, you can also reach PSIRT by telephone:

1 877 228-7302

1 408 525-6532


Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive information that you send to Cisco. PSIRT can work from encrypted information that is compatible with PGP versions 2.x through 8.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.


13 Obtaining Technical Assistance

Cisco Technical Support provides 24-hour-a-day award-winning technical assistance. The Cisco Technical Support & Documentation website on Cisco.com features extensive online support resources. In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.

Cisco Technical Support & Documentation Website

The Cisco Technical Support & Documentation website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, at this URL:

http://www.cisco.com/techsupport

Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

http://tools.cisco.com/RPF/register/register.do


Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support & Documentation website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.


Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

For a complete list of Cisco TAC contacts, go to this URL:

http://www.cisco.com/techsupport/contacts

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
