Following is the information required to install the router chassis.
Follow this procedural path to install your router:
This section guides you through the installation of the router and includes information on safety, inspecting the system, preventing electrostatic discharge (ESD) damage, tools and parts required, rack mounting, wall mounting, and making external cable connections.
Follow these guidelines to ensure general safety:
 | 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. |
Do not unpack the router until you are prepared to install it. If the final installation site will not be ready for some time, keep the router in the shipping container to prevent accidental damage. When you have determined where you want the router installed, proceed with the unpacking. The router, cables, publications, and any optional equipment you ordered might be shipped in more than one container. When you unpack each shipping container, check the packing list to ensure that you received all of the following items:
Inspect all items for shipping damage. If anything appears damaged, or if you encounter problems when installing or configuring your system, contact a service representative.
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the router chassis is electrically connected to earth ground. Wear an ESD wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted chassis frame surface to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.
 | Caution For safety, periodically check the resistance value of the antistatic strap, which should be within the range of 1 and 10 Mohms. |
Following are the tools and parts required to install the router:
In addition, you might need the following additional external equipment:
Rack and wall mounting procedures are described in a separate publication included with the optional rack mount kit. If you intend to rack mount the router, do so before making the external connections.
Following are the procedures for making external connections to the router. Figure 1 shows the rear panel of the router with the following connectors:
Cisco Systems declaration of operating conditions:
The Cisco 2000 is designed to meet the requirements of NET1 and NET2.
Interconnection directly, or by way of other apparatus, of ports marked:
"Safety Warning -- See instructions for use"
with ports marked or not so marked may produce hazardous conditions on the network and that advice should be obtained from a competent engineer before such a connection is made.
The ports marked "Ethernet," "Token Ring," "Console," and "AUX" have a safety warning applied to them as follows:
"These ports do not provide isolation sufficient to satisfy the requirement of BS6301; apparatus connected to these ports should either have been approved to BS6301 or have previously been evaluated against British Telecommunications plc (Post Office) Technical Guides 2 or 26 and given permission to attach; any that other usage will invalidate any approval given to this apparatus."
Connection of Power Supply. The Cisco 2000 is intended for use when supplied with power from a supply providing 220-240 VAC, 50/60 Hz up to 5 Amps.
Other usage will invalidate any approval given to this apparatus if as a result it ceases to comply with BS6301: 1989.
The Cisco 2000 is brought into service by the supplier.
The ports marked "Ethernet," "Token Ring," "Console," and "AUX" are SELV circuits. SELV circuits should only be connected to other SELV circuits.
Follow these steps to make external connections to your router:
Step 1 Connect the Ethernet port to the network as shown in Figure 2.
Step 2 Extend the Ethernet cable as shown in Figure 3.
Step 3 Connect the Token Ring port to the network as shown in Figure 4.
Step 4 Connect the serial ports to the network as shown in Figure 5.
Step 5 Connect the console and auxiliary ports as required for your method of configuration. Your terminal should be configured for 9600 baud, 8 data bits, no parity, and 1 stop bits.
Step 6 Connect the power cable between the router and the AC source.
After the router hardware is installed, the system is ready to be powered on and configured. For software configuration information, refer to the following publications:
To order these or additional associated publications, refer to the Service and Support card that accompanied your router.
This section includes the following reference information:
The key to problem solving in this system is to try to isolate the problem to a specific subsystem. By comparing what the system is doing to what it should be doing, the task of isolating a problem is greatly simplified.
Check the following items to help isolate the problem:
The System OK LED should be on after the system initializes correctly. (See Figure 1.)
