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/Tyco number 32957 terminals and 5/16 to 3/8 inch (8 to 9 mm) for Amp/Tyco number 34852 terminals.
Step 3 Crimp the terminals onto the DC power input and safety ground wires.
Step 4 Remove the plastic safety 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 12. Tighten the terminal screws to 10.0 ± 0.5 in-lb (1.1 ± 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 10.0
± 0.5 in-lb (1.1
± 0.05 N-m).
Figure 12 DC Power Connections for Cisco 3825 Routers (Typical)
Figure 13 DC Power Connections for Cisco 3845 Routers
Step 6 Install the plastic safety covers over the terminals. (See Figure 14 or Figure 15.)
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 14 or Figure 15. Make sure that the wires do not project above or below the front panel of the router.
Step 8 If a second power supply is installed and intended for use, repeat Step 1 through Step 7 for the second power supply.
Step 9 Turn on power to the DC circuit. Be sure to remove tape used to secure the circuit-breaker switch in the OFF position.

Figure 15 DC Wire Routing and Attachment for Cisco 3845 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 a Cisco 3825 series integrated router.
Caution Dual sources with opposite-polarity grounding damage equipment.
In Figure 16, either the positive source terminal or the negative source terminal is tied to ground.
Figure 16 Connecting to One Source Only—Source A or Source B
In Figure 17, source A and source B share common negative terminal connections.
Figure 17 Connecting Source A and Source B with Common Negative Terminals
In Figure 18, 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 17, discharging does not occur and there is no restriction requiring that source A and source B voltages be equal.
Figure 18 Connecting Source A and Source B with Common Positive Terminals
In Figure 19, 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 19.

Connecting the Router to Backup Power
The Cisco 3845 router operates in redundant mode when two power supplies are installed. The Cisco 3825 router has one internal power supply and a connector for mating to an external backup power source.
To connect the Cisco 3825 router to the external Cisco Redundant Power System (RPS), remove the RPS connector cover from the bezel and connect the RPS cable. (See Figure 20 and Figure 21.)
See the Cisco RPS-675 Hardware Installation Guide for more information about RPS power connections. To locate this documents, see the "Where to Go Next" section.
Note For information about installing a second power supply in the Cisco 3845 router, see the Cisco 3800 series hardware installation documentation at the following URL:
http://cisco.com/en/US/products/ps5855/prod_installation_guides_list.html
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.

WAN, LAN, and Voice Connections
The connections and cables listed in Table 3 are described in detail in the Cisco 3800 series hardware installation documents at the following URL:
http://cisco.com/en/US/products/ps5855/prod_installation_guides_list.html
Note An Ethernet cable is typically provided with the router. Additional cables and transceivers can be ordered from Cisco. For ordering information, contact customer service. For cable pinouts, see the
Cisco Modular Access Router Cable Specifications document.
Warning Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Statement 1036
Warning Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. Statement 1037
Warning Class 1 laser product. Statement 1008
Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect Gigabit Ethernet ports using RJ-45 connectors for shielded twisted pair cable only to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

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 3800 series 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.)
•PC with HyperTerminal or similar 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 "Power Connections" section.)
•Suitable PC COM port is selected in the terminal emulation program.
•You have selected passwords for access control.
•You have determined the IP addresses for the Ethernet and serial interfaces.
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.
Power-Up Procedure
To power up your Cisco router and verify that it goes through its initialization and self-test, perform this procedure. When the procedure is finished, the Cisco router is ready to configure.
Note To view the boot sequence, you must have a console connection to the Cisco 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 on the router. The SYS LED blinks green on both the Cisco 3825 and Cisco 3845 routers. During the boot process, the SYS PWR LED on the Cisco 3825 chassis is steady green, and the SYS PWR1 LED or SYS PWR2 LED on the Cisco 3845 chassis are off. If this does not happen, see the "Troubleshooting" document in the online Cisco 3800 series hardware installation documentation at the following URL:
http://cisco.com/en/US/products/ps5855/tsd_products_support_troubleshoot_and_alerts.html
Startup messages appear in your terminal emulation program window. After Cisco IOS software has finished booting, the SYS LED for both routers is steady green, and the SYS PWR1 LED or SYS PWR2 LED on the Cisco 3845 chassis is steady green.
Caution Do not press any keys on the keyboard until the messages stop and the SYS LED is steady 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.
Verify the Front Panel LED Indications
