Installing Your Router

To install the Cisco 811 or Cisco 813 router, perform the following tasks in the order listed:

Step 1 Connect the Ethernet devices to the router. See the "Connecting Ethernet Devices" section.

Step 2 Connect the ISDN line to the router. See the "Connecting an ISDN Line" section.

Step 3 If you have a Cisco 813 router, you can connect an optional digital telephone. See the "Connecting a Digital Telephone" section.

Step 4 If you have a Cisco 813 router, you can connect an optional analog telephone, fax, or modem. See the "Connecting an Analog Telephone, Fax, or Modem" section.

Step 5 Connect a terminal or PC to the router for software configuration using the command-line interface (CLI) or troubleshooting. See the "Connecting a Terminal or PC" section.

Step 6 Connect the router to the power source. See the "Connecting the Power Supply" section.

Step 7 Mount your router. See the "Mounting Your Router" section.

Step 8 Verify the router installation. See the "Verifying Installation" section.

Connecting Ethernet Devices

Table 3-1 lists the Ethernet devices you can connect to the router, connections for each device, and the settings of the router TO HUB/TO PC button (the default setting is IN).

¹Cisco provides a yellow straight-through cable. You must provide required crossover or additional straight-through cables. For details on cables, see "Cabling" in "Preparing for Installation."

²Hub vendors choose different names for the button controlling cable selections. This table uses the Cisco 1528 Micro Hub 10/100 with an MDI/MDI-X button as an example. Determine the button name and setting for your particular hub. See your hub documentation for details.

³On the Cisco 813 router, the TO HUB/TO PC button affects only the ETHERNET 1 port.

Connecting Hubs

If you have a Cisco 813 router, you can connect up to four hubs.

Before connecting a hub, perform the following steps:

Step 1 See Table 3-1 for router settings.

Step 2 Choose the Ethernet cable.

Step 3 Review the steps in Figure 3-1.

Caution Always connect the yellow cable or an Ethernet cable to the yellow ports on the router. Do not connect the cable to an ISDN S/T or U port or to a DSU. Connecting the cable to the wrong port or DSU can damage your router.

Figure 3-1 Connecting a Hub

To verify your hub connection, make sure that one of the following LEDs is on after you have completed the router installation:

•ETHERNET 1 on the Cisco 811 router front panel.

•ETHERNET 1, 2, 3, or 4 on the Cisco 813 router front panel.

If the LED is not on, see Table 4-2 in "Troubleshooting."

Connecting a Server, PC, or Workstation

Before connecting a server, PC, or workstation, see Table 3-1 to determine how to set the router TO HUB/TO PC button. Also, check your device to make sure it has a 10- or 10/100-Mbps NIC.

To connect one of these devices, follow the steps in Figure 3-2.

Caution Always connect the yellow cable or an Ethernet cable to a yellow port on the router. Do not connect the cable to an ISDN S/T or U port or to a DSU. Connecting the cable to the wrong port or DSU can damage your router.

Figure 3-2 Connecting Server, PC, or Workstation

To verify your connection, make sure that one of the following LEDs is on after you have completed router installation:

•ETHERNET 1 on the Cisco 811 front panel.

•ETHERNET 1, 2, 3, or 4 on the Cisco 813 front panel.

If the LED is not on, see Table 4-2 in "Troubleshooting."

Connecting an ISDN Line

Warning Network hazardous voltages are present in the ISDN cable. If you detach the ISDN cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are present on the system card in the area of the ISDN port (RJ-11 connector), regardless of when power is turned to standby.

Warning Do not work on the system or connect or disconnect cables during periods of lightening activity.

Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunications line cord.

Caution Always connect the red cable to the red ISDN U port on the router. Do not connect the cable to a yellow Ethernet port. This will damage your router.

Caution If a power failure occurs, the router stops communicating with other devices.

Connecting an ISDN U Line

Follow the steps in Figure 3-3 to connect an ISDN U line.

Figure 3-3 Connecting an ISDN U Line

Connecting an ISDN S/T Line

Follow the steps in Figure 3-4 to connect an ISDN S/T line.

Figure 3-4 Connecting an ISDN S/T Line

Connecting a Digital Telephone

If you have a Cisco 813 router, you can connect it to a digital (ISDN) telephone using the ISDN S/T interface. This digital device connects to basic telephone services through the ISDN line. However, you must provide the following equipment:

•Data service unit (DSU) with two S/T interfaces and one U interface.

•ISDN S/T cable to connect the DSU S/T port to the ISDN S/T port on the router.

Figure 3-5 Connecting a Digital Telephone to the Cisco 813 Router

Connecting an Analog Telephone, Fax, or Modem

If you have a Cisco 813 router, you can connect two devices, such as an analog touchtone telephone, fax machine, or modem. Each device is connected to basic telephone services through the ISDN line.

To connect an analog telephone, fax machine, or modem, follow the steps in Figure 3-6. You must provide the telephone cable to connect each device. The telephone cable is usually provided with the device.

The gray PHONE 1 and 2 ports are RJ-11 connectors.

Warning This equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do not touch the RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11 port, or the associated circuit-board when the ringer is active. The ringer is activated (indicated by a clicking sound) by an incoming call.

Caution Do not connect the router telephone ports to the telephone wall jack. These ports are not meant for direct connection to a public network. This connection can damage your router.

Connecting a Terminal or PC

To connect a terminal or PC from which you can configure the software or troubleshoot, follow the steps in Figure 3-7.

Figure 3-7 Connecting a Terminal or PC

Connecting the Power Supply

To connect the power supply, follow the steps in Figure 3-8.

Warning The device is designed to work with TN power systems.

Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 16A international) is used on the phase conductors (all current-carrying conductors).

Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.

Figure 3-8 Connecting the Power Supply

Mounting Your Router

You can mount your router on one of the following surfaces:

•Table or other horizontal surface

•Wall or other vertical surface

Mounting on a Table

You can mount your router on a table or other horizontal surface. Do not cover or obstruct router vents that are located on the router sides.

Mounting on a Wall

You can mount your router on a wall or other vertical surface by using the molded mounting brackets on the bottom of the router and two number-six, 3/4-in. (M3.5 x 20 mm) screws. You must provide the screws. Figure 3-9 shows the mounting brackets.

Caution If the wall to which you mount your router is drywall, use two hollow wall-anchors (1/8 in. with 5/16-in. drill bit or M3 with 8-mm drill bit) to secure the screws. If the screws are not properly anchored, the strain of the network cable connections could pull the router from the wall.

Figure 3-9 Wall-Mounting Brackets (Bottom of Router)

When mounting the router, the following conditions must be met:

•Because you will use the LEDs as status and problem indicators, the LEDs on the front panel must face upward and be easily visible.

•The back panel must face downward to reduce strain on the cable connections.

•The power supply must rest on a horizontal surface such as the floor or a table. If the power supply is not supported, it might place strain on the power supply cable and cause it to disconnect from the connector on the router back panel.

To mount the router, follow the steps in Figure 3-10.

Where to Go from Here

You have completed the hardware installation and are ready to configure the software. Choose one of the following options:

•If you are an inexperienced network administrator, Cisco strongly recommends that you use the Cisco 800 Fast Step application. For information about using this application, see the Cisco 800 Fast Step CD-ROM and online help.

•If you are an experienced network administrator and want to use the command-line interface to configure the software, see the
Cisco 800 Series Routers Software Configuration Guide.
