Chapter 1 Overview Field-Replaceable Units Port Adapters The port adapters installed in Cisco 7100 series VPN routers are of the same type as those installed in the Cisco 72xx family routers. For information on supported port adapters, refer to the Cisco Product Catalog or contact your local sales representative. The port adapters provide network interfaces to connect the router to external networks.
Chapter 1 Overview Field-Replaceable Units Note The Cisco 7100 series VPN routers do not support an ISM and an ISA in the same chassis. The boot LED remains lit when the ISA/ISM is configured for MPPE, and it starts to pulsate after booting when the ISA/ISM is configured for IPSec. The ISA/ISM functions normally whether the boot LED is pulsating or is solid. See the Integrated Service Adapter and Integrated Service Module Installation and Configuration for more information on configuring the ISA/ISM.
Chapter 1 Overview Field-Replaceable Units • The system bus recognizes the ISM. If either of these conditions is not met, or if the router initialization fails for other reasons, the enabled LED does not go on. Caution To ensure adequate airflow across the router components, an ISM or a blank service module must be installed in slot 5. The product number for the blank service module is SM-BLANK=.
Chapter 1 Overview Field-Replaceable Units VPN Acceleration Module (VAM) The VPN Acceleration Module (VAM) is a single-width acceleration module. The VAM supports LAN/WAN media and full Layer 3 routing services. VAMs provide hardware-assisted tunneling and encryption services for virtual private network (VPN) remote access, site-to-site intranet and extranet applications, including security, quality of service (QoS), firewall and intrusion detection, and service-level validation and management.
Chapter 1 Overview Field-Replaceable Units SM-VAM The SM-VAM resides in slot 5 in the Cisco 7100 series VPN routers. The SM-VAM has three LEDs, as shown in Figure 1-30. Table 1-12 lists the colors and functions of the LEDs.

Chapter 1 Overview Functional Overview You can also use arguments such as the interface type (Ethernet, Token Ring, ATM, and so forth) and the slot/port number to display information about a specific interface only. The following example shows the display for the fixed LAN (Fast Ethernet interface) port 0 in slot 0: Router# show interfaces fastethernet 0/0 FastEthernet0/0 is up, line protocol is up Hardware is DEC21140A, address is 0050.73ff.6300 (bia 0050.73ff.6300) Internet address is 10.0.0.
Chapter 1 Overview Functional Overview If the MAC addresses were stored on each port adapter, OIR would not function because you could never replace one port adapter with an identical one; the MAC addresses would always be different. Also, each time a port adapter was replaced, other devices on the network would have to update their data structures with the new address and, if they did not do so quickly enough, could cause the same MAC address to appear in more than one device at the same time.

C H A P T E R 2 Preparing for Installation This chapter describes the tasks you must perform before you begin to install a Cisco 7100 series VPN router and includes the following sections: Warning • Tools and Parts Required, page 2-1 • Shipping Container Contents, page 2-2 • Safety Guidelines, page 2-2 Only trained and qualified personnel should be allowed to install, replace, or service this equipment. This equipment contains an energy hazard. Disconnect the system before servicing.
Chapter 2 Preparing for Installation Shipping Container Contents Shipping Container Contents Ensure that the correct Cisco 7100 series router is in the shipping container.
Chapter 2 Preparing for Installation Safety Guidelines Warning • Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught in the chassis. Fasten your tie or scarf and roll up your sleeves. • Wear safety glasses if you are working under any conditions that might be hazardous to your eyes. • Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
Chapter 2 Preparing for Installation Safety Guidelines Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. Warning When installing the unit, the ground connection must always be made first and disconnected last. • Do not work alone if potentially hazardous conditions exist. • Never assume that power is disconnected from a circuit. Always check.
Chapter 2 Preparing for Installation Safety Guidelines safely ground unwanted ESD voltages. To guard against ESD damage and shocks, the wrist strap and cord must operate properly. 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 between 1 and 10 megohms (Mohm).
Chapter 2 Preparing for Installation Safety Guidelines Site Requirement Guidelines Warning This unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location.
Chapter 2 Preparing for Installation Safety Guidelines • To mount the router between two posts or rails using the brackets, the inner clearance (the width between the inner sides of the two posts or rails) must be at least 17 inches (43.18 cm). • The height of the chassis is 3.5 inches (8.89 cm). • When mounting the router in four-post or telco-type racks, be sure to use all the screws and the brackets provided to secure the chassis to the rack posts.
Chapter 2 Preparing for Installation Safety Guidelines Note 22136 Chassis width 17.5 in. (44.45 cm) Chassis depth including cables 23.25 in. (59 cm) Cisco 7100 Series Router Footprint and Outer Dimensions Chassis depth 18.25 in. (46.36 cm) Figure 2-2 • Always install heavier equipment in the lower half of a rack to maintain a low center of gravity and prevent the rack from falling over.
Chapter 2 Preparing for Installation Safety Guidelines Temperature and Humidity Requirements Table 2-1 lists the operating and nonoperating environmental site requirements. The ranges listed are those within which Cisco 7100 series routers continue to operate; however, a measurement that is approaching the minimum or maximum of a range indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental anomalies before they approach a maximum operating range.
Chapter 2 Preparing for Installation Safety Guidelines Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. The Cisco 7100 series router installation must comply with all applicable codes and is approved for use with copper conductors only.
Chapter 2 Preparing for Installation Safety Guidelines If wires exceed recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding.
Chapter 2 Preparing for Installation Safety Guidelines Ethernet Connections There are two 10BaseT/100BaseTX Fast Ethernet ports on the rear panel of the router. Both ports use unshielded twisted-pair (UTP) cable. We recommend Category 5 UTP cable. The maximum segment distance is 328 feet (100 meters). UTP cables look like the cables used for ordinary telephones; however, UTP cables meet certain electrical standards that telephone cables do not. Cables are not included.
Chapter 2 Preparing for Installation Safety Guidelines Console and Auxiliary Port Considerations Cisco 7100 series routers include an asynchronous serial console and auxiliary port. The console and auxiliary ports provide access to the access server either locally (with a console terminal) or remotely (with a modem).

Chapter 5 Troubleshooting the Installation Troubleshooting Overview Problem Solving Using a Subsystems Approach The key to solving problems with the system is isolating the problem to a specific subsystem. The first step in solving startup problems is to compare what the system is doing to what it should be doing. Because a startup problem is usually caused by a single component, it is more efficient to first isolate the problem to a subsystem rather than troubleshoot each component in the system.
Chapter 5 Troubleshooting the Installation Troubleshooting the Power Subsystem If this LED remains off when you start the router, it is probably a problem with the network processor card. Contact your service representative for technical assistance. – Each enabled LED goes on and indicates that the port is initialized and enabled for operation by the system. These LEDs go on during a successful router boot and remain on during normal operation of the router.
Chapter 5 Troubleshooting the Installation Troubleshooting the Processor Subsystem Troubleshooting the Network Processor Card The procedures in this section assume that the router is in the original factory configuration, and that you have not made changes to your configuration file.
Chapter 5 Troubleshooting the Installation Troubleshooting the Cooling Subsystem Troubleshooting the Cooling Subsystem Check the following to help isolate a problem with the cooling system: • When you start up the system, do the fans start operating? To determine if the fans are operating, listen for them. In noisy environments, place your hand on the front of the chassis to feel for air being pushed out of the vents. – If yes, the power to the fans is good.
