This chapter provides information on the following topics:
This section provides information on safety, mounting your router, and unpacking the contents of the router box.
This section discusses the safety warnings and electrostatic and router damage information for the Cisco 827 routers.
Before installing the router, read the following warnings:
 | Warning Only trained and qualified personnel should be allowed to install or replace this equipment. |
| Warning Read the installation instructions before you connect the system to its power source. |
| Warning Before working on a system that has a standby/off switch, turn the power to standby and unplug the power cord. |
| Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. |
| Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. |
| Warning Ultimate disposal of this product should be handled according to all national laws and regulations. |
| Warning
If the symbol of suitability with an overlaid cross ( ) appears above a port, you must not connect the port to a public network that follows the European Union standards. Connecting the port to this type of public network can cause severe injury or damage your router. |
Electrostatic discharge (ESD) is a transfer of electrostatic charge between bodies of different electrostatic potentials, such as an operator and a piece of electrical equipment. It occurs when electronic components are improperly handled, and it can damage equipment and impair electrical circuitry. Electrostatic discharge is more likely to occur with the combination of synthetic fibers and dry atmosphere.
Always use the following ESD-prevention procedures when removing and replacing components:
Step 1 Wear an ESD-preventive wrist strap that you provide, ensuring that it makes good skin contact.
 | Caution To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. Always follow the guidelines in the preceding section, "Safety." |
Step 2 Do not touch any exposed contact pins or connector shells of interface ports that do not have a cable attached.
If cables are connected at one end only, do not touch the exposed pins at the unconnected end of the cable.
| Caution eriodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohms). |
Figure 2-1 shows the items included with your router. If any of the items is missing or damaged, contact your customer service representative.
To prepare for installation, follow these steps:
Step 1 Remove the yellow Ethernet cable, light blue console cable, lavender ADSL cable, product documentation, and Cisco 800 Fast Step CD-ROM from the Open Me First bag. Remove the desktop power supply and the black power cord from the accessory kit. Gather the Ethernet devices to be connected to the router: hub, server, workstation, or PC.
Step 2 Obtain the ADSL line.
Step 3 If you plan to connect an analog telephone or fax machine, gather these devices. You must also provide the telephone cable to connect each device (usually this cable is provided with the device).
Step 4 If you plan to configure the software using a terminal or PC connected to the router, provide the terminal or PC.
Step 5 If you plan to use the cable lock feature, provide a Kensington or equivalent locking cable.
Follow these guidelines when connecting devices to your router:
) appears above a port, you can connect the port directly to a public network that follows the European Union standards.
| Warning
If the symbol of suitability with an overlaid cross () appears above a port, you must not connect the port to a public network that follows the European Union standards. Connecting the port to this type of public network can cause severe injury or damage to your router. |
To install the Cisco 827 routers, you need to perform the following tasks in the following order:
1. Connect the Ethernet devices to the router.
2. Connect the ADSL line.
3. Connect an optional analog telephone or fax machine.
4. Connect a terminal or PC to the router (for software configuration using the command-line interface [CLI] or troubleshooting).
5. Connect the router to the power source.
6. Verify the router installation.
7. Mount the router.
Table 2-1 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).
| Network Device Connected To Router | Router Port | Ethernet Cable Type1 | Router HUB/NO HUB Button Setting | Network Device Button Setting2 |
|---|---|---|---|---|
Hub with equivalent to | ETHERNET port 1 | Straight-through | IN | MDI (IN) |
Hub with equivalent to | ETHERNET port 1 | Straight-through | OUT | MDI-X (OUT) |
Hub without equivalent to router TO HUB/TO PC button | ETHERNET port 1 | Straight-through | OUT | MDI-X (OUT) |
Server, PC, or workstation | ETHERNET port 1 | Straight-through | OUT | - |
| 1Cisco provides a yellow straight-through cable. You provide crossover or additional straight-through cables. For details on cables, refer to Appendix A. 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. Refer to your hub documentation for details. |
Before connecting a hub, refer to Table 2-1. To connect one of these devices, follow the steps in Figure 2-2.
To verify your hub connection, ensure that the Ethernet 1 LED on the front panel is on after you have completed the router installation.
If the LED is not on, refer to Table 3-2 in Chapter 3 for troubleshooting information.
Before connecting the server, PC, or workstation, refer to Table 2-1 to determine how to set the router To HUB/TO PC button.
To connect one of these devices, follow the steps in Figure 2-3.
To verify your connection, ensure that the Ethernet 1 LED is on after you have completed router installation.
If the LED is not on, refer to Table 3-2 in Chapter 3 for troubleshooting information.
| Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. |
To connect an analog telephone or fax machine, follow the steps in Figure 2-5. You must provide the telephone cable to connect each device. The telephone cable is usually provided with the device.
The gray phone ports are RJ-11 connectors. If you are outside of North America, you must buy and attach adapters that allow your telephones or faxes to be connected to these RJ-11 connectors. In some countries, these adapters need additional electronics to convert the telephones or faxes to work properly with the router phone ports. For example, in the United Kingdom, you must buy an adapter that also provides a master socket, which causes incoming calls to ring the connected devices. For information on recommended master sockets, see Table 2-2.
| 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. |
