having to physically access the router, for fast, reliable upgrades.

• Network management—Allows you to remotely manage the rou ter. Cisco 7100 series VPN routers

support CiscoWorks and CiscoView network manage ment software .

–

CiscoW orks—Lets you monitor comple x internetworks that use Cisco routing devices and helps you plan, troubleshoot, and analyze your network. CiscoWorks uses the Simple Network Management Protocol (SNMP) to monitor an d control any SNMP device on the network.

–

CiscoView—A graphical SNMP-based device management tool that provides powerful real-time views of your networked Cisco devices. These views deliver a continuously updated physical picture of device configuration and performance conditions, with simultaneous views available f or multiple de vice sessions. CiscoView runs from a centralized network management site from which you can review, reconfigure, and monitor essential device data from a simple GUI (that displays information such as dynamic status reports, performance statistics, and network inquiries) without having to physically check connections for each device, module, or port at every different or remote location.

Cisco 7120 series routers have one power supply with one A C-input pow er receptacle; Cisco 7140 series routers have two power supplies with two AC-input power receptacles for power load-sharing and redundancy. A modular power cable connects each AC-inpu t power supply to the site AC power source. The router’s main power switch is located next to the AC-input power receptacles.

Cisco 7140 series routers will operate with power connected to either of the two power supplies. The second AC-input power supply simply enables power load-sharing and redundancy. There is no primary or secondary power supply for Cisco 7140 series routers.

We recommend powering the router from a 15A receptacle at the power source. On the side of each chassis are two chassis ground re ceptacles that provide a chassis ground connection

for a two-hole grounding lug. On the back of the chassis, there is a receptacle for electrostatic discharge (ESD) equipment. (See Figure 1-3 and Figure 1-4.)

Four internal fans draw cooling air into the chassis (back to front) and across internal components to maintain an acceptable operating temperature. There are four environmental sensors for monitoring the cooling air as it leaves the chassis. For more information on environmental monitoring, see the

“Environmental Monitoring and Reporting Functions” section on page 1-39.

Chapter 1 Overview

Caution To ensure the proper flow of cooling air acro ss the internal components, make sure a blank port adapter

Cisco 7120 Series Overview

is installed in an unoccupied port adapter slot. The product number for a blank port adapter is MAS-7100-PABLANK=.

The modular port adapter slides into the chassis slot and connects directly to the router; there are no internal cables to connect.

The port adapter, service module, fixed WAN interfaces, and fixed LAN interfaces connect to two Peripheral Component Interconnect (PCI) buses on the router’s backplane that provide a path to packet I/O memory and the system processor. For more information, see the “Peripheral Component

Interconnect Buses” section on page 1-33.

Cisco 7100 series VPN routers can be installe d on a tabl etop or in an equipment rack. Rubber feet for tabletop installation are included in the accessory kit that shipped with you r router. A rack-mount and cable-management kit is also standard equipment when Cisco 7100 series VPN routers are shipped from the factory. The kit provides the hardware needed to mount the router in a standard 19- or 23-inch, four-post or telco-type equipment rack. The kit also provides the hardware necessary to manage the interface cables attached to the router. The product number for the rack-mount kit is ACS-7100-RMK=. Instructions for setting the router on a tabletop, installing the router in an equipment rack, and attaching the cable-management bracket are the same for all Cisco 7100 series VPN models and are explained in

Chapter 3, “Installing a Cisco 7100 VPN Series Router.”

Chassis Slot and Logical Interface Numbering

In Cisco 7100 series VPN routers, the slot number is the loca tion in the chassis where the interface resides and the port number is the physical port associated with that slot. Cisco 7100 series router slots are numbered 0 through 5. Interfaces in the Cisco IOS software are identif ied by a type, slot number, and port number. The number of physical ports depends on the type of modular port adapter or fixed interface. For example, in a Cisco 7120-4T1, serial 1/0 indicates port 0 on the fixed serial interface in slot 1. (See Figure 1-5.)

Slots in the Cisco 7120 series are numbered as follows and are shown in Figure 1-31:

• Slot 0—Fixed LAN (Ethernet) interface

Interface Information in the Software

You can identify interfaces by using software commands. To display information about all interfaces, use the show interfaces command. To display information about a specific interface, use the show interfaces command with the interface type, slot number, and por t number in the format show interf aces type slot/port.

The following example shows how the show interfaces command, used without arguments, displays status information (including the slot and port number) for each interface in a Cisco 7100 series VPN router. In the following example, most of the status information for each interface is omitted:

MAC Addresses

For information on the other commands used to co nfigure the router , refer to t he Cisco IOS configuration guides and command references, which are available on the Documentation CD-ROM or in print.

The Media Access Control (MAC) or hardware address is a standardized data-link layer address that is required for certain network interface types. These addresses are not used by other devices in the network; they are specific and unique to each port. The router uses a specific method to assign and control the MAC addresses of its port adapters.

All LAN interfaces (ports) require unique MAC addresses. Typically, the MAC address of an interface is stored on a memory component that resides directly on the interface circuitry; however, the online insertion and removal (OIR) feature requires a di fferent method. (For a description of OIR, see “Online

Insertion and Removal” section on page 1-33.)

The OIR feature allows you to remove a port adapter and replace it with another identically configured one. If the new port adapter matches the port adapter you removed, the system immediately brings i t on line. To allow OIR, an address allocator with unique MAC addresses is stored in an EEPROM on the router. Each address is reserved for a specific port and slot in the router regardless of whether a port adapter resides in that slot. The MAC addresses are assigned to slot 3 in Cisco 7120 series routers and slot 4 in Cisco 7140 series routers. This address scheme allows you to remove a port adapter and insert the port adapter into other routers without causing the MAC addresses to move around the network or be assigned to multiple devices.

Cisco 7100 Series VPN Router Installation and Configuration Guide

1-32

78-6341-03

Page 33

Chapter 1 Overview

If the MAC addresses were stored on each port adapter , OIR would no t function because you could ne ver replace one port adapter with an identical one; the MAC addresses would always be dif ferent. Also, each time a port adapter was replaced, other devices on the netw ork would ha ve to update their data str uctures 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.

Note Storing the MAC addresses for every slot in one central location means the addresses stay with the

memory device on which they are stored.

Online Insertion and Removal

The modular port adapter installed in Cisco 7100 series VPN routers supports OIR. This functi on allows you to install and replace a port adapter while the router is operating; you do not need to notify the software or shut down the system power. This provides a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.

The following is a functional description of OIR for background information only; for specific procedures for installing and replacing a port adapter in a Cisco 7100 series VPN router, see the configuration note that ships with each port adapter.

Functional Overview

Each port adapter has a bus connector that connects it to the router. Each connector has a set of tiered pins in three lengths that send specific signals to the system as they make contact with the port adapter. The system assesses the signals it receives and the order in which it receives them to determine if a port adapter is being removed or inserted into the rou ter. From these signals, the system determines whether to reinitialize a new interface or shut down a removed interface. For example, when you insert a port adapter, the longest pins make contact with the port adapter first, and the shortest pins mak e contact last. The system recognizes the signals and the sequence in which it receives them.

When you remove or insert a port adapter in a Cisco 7100 series VPN router, the port adapter pins send signals to notify the system, which then performs as follows:

1. Rapidly scans the system for configuration ch anges.

2. Initializes all newly inserted port adapters, noting any removed interfaces and placing them in the

administratively shutdown state.

3. Brings all previously configured interfaces on the port adapter back to the state they were in when

they were removed. Any newly inserted interfaces are put in the administratively shutdown state, as if they were present (b ut not conf igured ) at boot time. If a similar port adapter type is reinserted in to a slot, its ports are configured and brought on line up to the port count of the original port adapter.

Peripheral Component Interconnect Buses

All interfaces connect to two Peripheral Compon ent I nte rconnect (PCI) b u ses on the router that pro vide a path to packet I/O memory and the network processor. Interfaces in slots 1, 3, and 5 use PCI bus 0 and interfaces in slots 0, 2, and 4 use PCI bus 1. For port adapters that are installed in the modular port adapter slots (slot 3 or slot 4), use the guidelines described in Appendix A, “Modular Port Adapter

Configuration Guidelines,” to ensure sufficient bandwidth.

The maximum recommended bandwidth points on each PCI bus is 600 point s. F or best performance we recommend that you avoid using port adapters that exceed the total available bandwidth for your router.

The network processor card consists of the following components:

• Reduced Instruction Set Computing (RISC) microprocessor

• T wo system controllers—Provide processor access to two separate banks of SDRAM and that permit

devices on both PCI buses to access either SDRAM bank. This means that devices on different PCI buses can access different SDRAM banks simultaneously.

• Upgradable memory modules—SDRAM system memory is up to 256 MB. (SDRAM packet

memory is fixed at 64 MB.) SDRAM memory stores packets received or sent from network interfaces, routing tables, and network accountin g applications. There are two independ ent SDRAM memory arrays that allow concurrent access by interfaces and the processor.

Note The network processor card contains two SDRAM slots for user-configurable system and packet

memory, DIMM 1 and DIMM 2. The amount of memory installed in slot DIMM 1 must be greater than or equal to the amount of memory installed in slot DIMM 2, and slot DIMM 2 can be zero.

Slot DIMM 0 is used exclusively for packet memory and is fixed at 64 MB in the factory.

• Cache memory

–

Cisco 7120 series routers have two levels of cache: a primary cache that is internal to the microprocessor and a secondary, 2-MB (fixed) external cache that provides additional high-speed storage for data and instructions.

Cisco 7140 series routers have three levels of cache: a primary and a secondary cache that are internal to the microprocessor and a tertiary, 2-MB (fixed) external cache that provides additional high-speed storage for data and instructions.

• Four environmental sensors—Monitor the cooling air as it leaves the chassis.

• Boot ROM—Stores sufficient code for booting the Cisco IOS software.

• Flash memory single in-line memory module (SIMM)—Stores the boot image used to boot the

router.

• NVRAM—Stores the system configuration and environmental monitoring logs (the NVRAM uses

lithium batteries to maintain its contents when disconnected from power).

• Console port—Provides access for a local terminal and is equipped with an RJ-45 receptacle.

• Auxiliary port—Provides access for a modem for remote access and is equipped with an RJ-45

receptacle.

• Two fixed LAN ports—Provide 10BaseT/100BaseTX autosensing Ethernet/Fast Ethernet (full and

half duplex) and are equipped with an RJ-45 receptacle.

• T wo PC Card slots—Contain Flash Disks or Flash memory cards that provide the default Ci sco IOS

Environmental Monitoring and Reporting Functions

Environmental monitoring and reporting functions are controlled by the network processor and allow you to maintain normal system operation by identifying and resolving adverse conditions that might disrupt operation.

The environmental monitoring functions constantly monitor the internal chassis air temperature and power supply voltages and currents. The power supply monitors its own voltage and temperature and shuts itself down if it detects a critical condition within the power supply. The reporting functions periodically log the values of measured parameters so that you can retrieve them for analysis later, and the reporting functions display warnings on the console if any of the monitored parameters exceed defined thresholds.

The front and back of the chassis must remain unobstructed to ensure adequate airflow and prevent overheating inside the chassis; we recommend at least 3 inches (7.6 cm) of clearance. Temperature sensors in the router monitor the internal air temperature and send warning messages when the internal air temperature exceeds the specified threshold.

Functional Overview

Environmental Monitoring

The environmental monitoring functions use four sensors to monitor the temperature of the cooling air as it moves through the chassis.

If the air temperature exceeds a defined threshold, the router displays warning messages on the console terminal. The system stores the present parameter measuremen ts for both temperature and po wer v oltage in NVRAM so you can retri eve them later.

In addition, the power supply monitors the internal power supply temperature and voltages. A power supply is either within tolerance (normal) or out of tolerance (critical). If the internal power supply temperature or voltage reaches a critical le ve l, the power supply shuts down wi thout any int eraction with the system processor.

The environmental monitoring functions use the following levels of status conditions to monitor the system:

• Normal—All monitored parameters are within normal tolerances.

• Warning—The system has exceeded a specified threshold. The system continues to operate, but

operator action is recommended to bring the system back to a normal state.

• Critical—An out-of-tolerance temperature or voltage condition exists. The system continues to

operate; however, immediate operator action is required.

Displaying Environmental Status Reports

Cisco 7100 series VPN routers display warning messages on the console if chassis interface-monitored parameters exceed a desired threshold. You can also retrieve and display environmental status reports with the show environment, show environment all, show environment last, and show environment table commands. Parameters are measured and reporting functions are updated e very 60 seconds. A brief description of each of these commands follows.

Caution To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Overtemperature

conditions can occur if the system is drawing in the exhaust air of other equipment. Ensure adequate clearance around the sides of the chassis so that cooling air can flow through the chassis interior unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of other device.
