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 chassis 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:
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 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 external equipment:
If you want to rack or wall mount your chassis, refer to the Cisco 3000 Rack-Mount/Wall-Mount Installation configuration note publication that accompanied your optional rack-mount/wall-mount kit.
Following are the procedures for making external connections to the router. Figure 1 shows partial rear-panel views of the six router models.
Cisco Systems declaration of operating conditions:
The Cisco 3000 Series 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 Gateway Server 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 3000 Series 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.
Following is the procedure for connecting cables to the router:
Step 1 Connect the Ethernet port to a transceiver as shown in Figure 2.
Step 2 If necessary, extend the Ethernet cable as shown in Figure 3.
Step 3 Connect the Token Ring port to a media attachment unit (MAU) as shown in Figure 4.
Step 4 Connect the serial ports to a modem or CSU/DSU as shown in Figure 5.
Step 5 The Basic Rate Interface (BRI) port, a female RJ-45 connector (see Figure 6), is located on the right of the chassis rear panel. (See Figure 1.) Using an RJ-48 cable, connect the BRI port to the Integrated Services Digital Network (ISDN) through the NT1.
| Warning Network hazardous voltages are accessible in the BRI cable. If you detach the BRI cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages are accessible on the system card in the area of the BRI port (RJ-45 connector), even when power is turned off. (See Figure 7.) |
Step 6 Connect the console and auxiliary ports as required for your method of configuration or if future reconfiguration is required. Your terminal should be configured for 9600 baud, 8 data bits, no parity, and 1 stop bits. (See Figure 1 for the location of the console and auxiliary ports.)
Step 7 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 information on router configuration, 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 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:
For more complete network troubleshooting information, refer to the Troubleshooting Internetworking Systems publication.
