Chassis Overview—Front View

The front of Cisco 7200 series routers provides access to an input/output (I/O) controller and up to two, four, or six network interface port adapters. The I/O controller has a local console port for connecting a data terminal (or data terminal equipment [DTE]) and an auxiliary port for connecting a modem (or other data communications equipment [DCE]) or other devices for configuring and managing the router; PC Card slots for PC Cards or Flash Disks; and optional Ethernet, Fast Ethernet, or Gigabit Ethernet ports.

The NPE-G1 and NPE-G2 work with the I/O controller when installed in a Cisco 7200 VXR router. The NPE-G1 or NPE-G2 can also be used without an I/O controller; both have three Gigabit Ethernet interfaces, with a total of three of six ports (three RJ-45 and three GBIC modules on the NPE-G1, or three SFP modules on the NPE-G2) available at one time, a CompactFlash Disk, and a console port and auxiliary port. In addition, the NPE-G2 has a Fast Ethernet Management port and two USB ports for security tokens and data file storage. The Port Adapter Jacket Card can be used in the I/O controller slot, if an NPE-G1 or NPE-G2 is installed.

Figure 1-1 shows a Cisco 7206VXR with installed port adapters and an I/O controller with a Fast

Ethernet port.

Chapter 1 Cisco 7200 Series Port Adapter Installation Requirements

Chassis Overview—Rear View

Note A blank port adapter is installed in port adapter slot 5 in Figure 1-1. To ensure adequate airflow across

the router’s internal components, ensure that each port adapter slot is filled with either a port adapter or a blank port adapter.

The port adapters installed in Cisco 7200 series routers are of the same type as those installed in other Cisco 7000 family routers. Cisco 7200 series routers support the online insertion and removal (OIR) of installed port adapters.

Chassis Overview—Rear View

Figure 1-2 Cisco 7200 Series Router—Rear View

The rear of Cisco 7200 series routers provides access to a network processing engine (NPE) or network services engine (NSE) and up to two 280W AC-input or DC-input power supplies (see Figure 1-2).

Most NPEs and the NSE have no external connectors or LEDs. There is a handle for removing and installing the engines and two captive installation screws for securing them to the chassis.

The NPE-G1 and NPE-G2 have external connectors for Gigabit Ethernet interfaces, and a console port and auxiliary port; the NPE-G2 also has a Fast Ethernet Management port. The NPE-G1 and NPE-G2 also have a cable-management bracket.

A fully configured Cisco 7200 series router operates with only one installed power supply; however, a second, optional power supply of the same type provides hot-swappable, load-sharing, redundant power. The power supply has the router’s main power switch and either an AC-input power receptacle, or three hardwired DC-input power leads (depending on the type of installed power supply). Adjacent to the power supply bays are two chassis grounding receptacles that provide a chassis ground connection for ESD equipment or a two-hole grounding lug (see Figure 1-2).

Chapter 1 Cisco 7200 Series Port Adapter Installation Requirements

Configuration Guidelines and Requirements

Note The Cisco 7200 series routers do not support a mix of installed AC-input and DC-input power

supplies. Figure 1-2 shows the rear of a Cisco 7200 series router configured with a single 280W AC-input power supply. (A power supply filler plate is installed over the second power supply bay.)

Three internal fans draw cooling air into the chassis interior and across internal components to maintain an acceptable operating temperature (see Figure 1-2). The three fans are enclosed in a tray that is located in the subchassis.

The I/O controller, port adapters, Port Adapter Jacket Card, power supplies, and NPE or NSE slide into their respective chassis slots and connect directly to the router midplane; there are no internal cables to connect.

Configuration Guidelines and Requirements

Understanding the relationship between the three Peripheral Component Interconnect (PCI) buses, I/O controller, and port adapters is important in understanding the rationale for the bandwidth point information that is provided in this document.

PCI Buses and Port Adapter and I/O Controller Architecture

All port adapters and service adapters installed in Cisco 7200 series routers connect to one of two Peripheral Component Interconnect (PCI) buses, mb1(left bus) or mb2 (right bus), on the router midplane that provide a path to packet I/O memory and the system (routing and switching) processor.

The optional ports on the I/O controller connect to a third PCI bus, mb0 (left bus), that connects to one of the PCI buses or to both of the PCI buses, depending on which network processing engine (NPE) or network services engine (NSE) is installed and supported in your system.

With an NPE-G1 or NPE-G2 installed, the I/O controller connects on the third PCI bus, mb0, which connects directly into the NPE-G1 or NPE-G2. When installed with the NPE-G1 or NPE-G2, the I/O controller does not take bandwidth from the two PCI buses (left and right) dedicated to the port adapters.

The Port Adapter Jacket Card, for use in the Cisco 7200 VXR routers and only with the NPE-G1 or NPE-G2, installs in the I/O controller slot on PCI bus mb0. Because the Port Adapter Jacket Card accepts only one port adapter, and the PCI bus provides another 600 bandwidth points, this bus cannot be oversubscribed because no port adapter is assigned more than 600 bandwidth points.

Guidelines for distributing the port adapters evenly between the two buses are given in the “Guidelines

for Installation” section on page 1-6.

Port Adapter Slot Numbering

Figure 1-3 Cisco 7200 Series Port Adapter Slot Numbering—Cisco 7206 Shown

Figure 1-3 shows the port adapter slot numbering for the Cisco 7200 series routers. Figure 1-4 shows the

port adapter slot numbering for the Cisco 7200 VXR routers with the Port Adapter Jacket Card installed.

For the Cisco 7202, Cisco 7204, and Cisco 7206 routers, port adapters in odd-numbered slots connect to PCI bus mb1 (left bus). Port adapters in even-numbered slots connect to PCI bus mb2 (right bus). The I/O controller connects to PCI bus mb0 (left bus), port adapter slot 0. The I/O controller is considered part of the left bus when calculating bandwidth points.

For the Cisco 7204VXR and Cisco 7206VXR routers, port adapters in odd-numbered slots connect to PCI bus mb1 (left bus). Port adapters in even-numbered slots connect to PCI bus mb2 (right bus). The I/O controller connects to PCI bus mb0 (left bus), port adapter slot 0. The I/O controller is considered part of the left bus when calculating bandwidth points, except in the case of the NPE-G1 or NPE-G2. With the NPE-G1 or NPE-G2 installed, the I/O controller connects on the third PCI bus, mb0, which connects directly into the NPE-G1 or NPE-G2, and so does not use bandwidth points.

Note The NPE-G1 and NPE-G2 installs only in the Cisco 7204VXR and Cisco 7206VXR routers.

Note The Port Adapter Jacket Card works only with an NPE-G1 or NPE-G2 installed.

The Port Adapter Jacket Card installs into the I/O controller slot on the third PCI bus, mb0. The Port Adapter Jacket Card is designated slot 0, and the port adapter installed in it is designated port adapter slot 7 on the Cisco 7206 VXR router, and slot 5 on the Cisco 7204 VXR router.

Guidelines for Installation

Cisco 7200 series routers have a finite data-carrying capacity, referred to as bandwidth, that affects the port adapter distribution in the chassis, as well as the number and types of port adapters you can install.

To ensure that your Cisco 7200 series router port adapter configuration is within the router operating limits, observe the following guidelines and requirements when planning to install a port adapter, network processing engine or network services engine, or I/O controller. Chapter 2, “Memory

Requirements,” provides information about various types of memory requirements for the hardware and

software that support port adapters.

Table 1-1 provides general guidelines for Cisco 7200 series routers.

Cisco 7200 Series Port Adapter Hardware Configuration Guidelines

OL-3875-11

Chapter 1 Cisco 7200 Series Port Adapter Installation Requirements

Installation Requirements Based on the NPE or NSE Installed

To ensure that your Cisco 7200 series port adapter configuration is within the router operating limitations, determine your model of network processing engine or network services engine and observe the following guidelines:

• For NPE-G1 or NPE-G2, go to the “NPE-G1 or NPE-G2 Bandwidth Calculation and Configuration

Instructions” section on page 1-8.

• NPE-G1 or NPE-G2 with a Port Adapter Jacket Card—Bandwidth Calculation and Configuration

Instructions, page 1-9

• For NPE-400, NPE-300 and NSE-1, go to the “NPE-400, NPE-300, and NSE-1 Bandwidth

Calculation and Configuration Instructions” section on page 1-9.

• For NPE-225, NPE-200, NPE-175, NPE-150, and NPE-100, go to the “NPE-225, NPE-200,

NPE-175, NPE-150, and NPE-100 Bandwidth Calculation and Configuration Instructions” section on page 1-11.

NPE-G1 or NPE-G2 Bandwidth Calculation and Configuration Instructions

Step 1 For each port adapter in your system, check the footnotes in Table 1-6 to see if any apply to your system.

Step 2 If you have any dual-wide port adapters in your system, carefully read the port adapter configuration

document to see what special conditions apply to these port adapters.

Step 3 Calculate the bandwidth points requirements. For each port adapter in your system, go to Table 1-6 and

write down the bandwidth points requirements. Use the blank Bandwidth Calculation Table, page 1-22, to record your requirements.

Note Do not calculate bandwidth points for an I/O controller if it is installed in the Cisco 7200 VXR

router with an NPE-G1 or NPE-G2. With the NPE-G1 or NPE-G2, I/O controllers do not use bandwidth or bandwidth points.

Step 4 Assign each port adapter in your system to a chassis slot.

• Make sure that the total bandwidth points for slots 0, 1, 3, and 5 (left bus) are less than or equal to

600.

• Make sure that the total bandwidth points for slots 2, 4, and 6 (right bus) are less than or equal to 600.

Step 5 Make sure that the bandwidth points are evenly distributed between the left (odd-numbered slots) and

right (even-numbered slots) buses. Include the I/O controller in your determination of balance for the left odd-numbered slots. Fill the slots in the following order: 2, 1, 4, 3, 6, 5.

Step 6 Check your Cisco IOS release and port adapter SDRAM memory requirements as detailed in Chapter 2,

“Memory Requirements.”.

You are finished calculating your port adapter configuration.

Cisco 7200 Series Port Adapter Hardware Configuration Guidelines

OL-3875-11

Chapter 1 Cisco 7200 Series Port Adapter Installation Requirements

Installation Requirements Based on the NPE or NSE Installed

Sample Bandwidth Configuration for the NPE-G1 or NPE-G2

This sample configuration is for a Cisco 7200 VXR chassis with an NPE-G1 or NPE-G2 installed. The maximum points allowed for each PCI bus is 600 points. When any I/O controller is installed with the NPE-G1 or NPE-G2, no bandwidth points are used. The Gigabit Ethernet interfaces on the NPE-G1 or NPE-G2 also require no bandwidth points.

NPE-G1 or NPE-G2 with a Port Adapter Jacket Card—Bandwidth Calculation and Configuration Instructions

The Port Adapter Jacket Card works only with the NPE-G1 or NPE-G2 installed in Cisco 7200 VXR router. Because of the third PCI bus provided by these network processing engines, the Port Adapter Jacket Card PCI bus mb0 provides an additional 600 bandwidth points. Only one port adapter can be inserted into the port adapter slot in the Port Adapter Jacket Card. Because no port adapter is assigned more than 600 bandwidth points, there is no need to do any calculation of points for port adapter slot 5 (Cisco 7204 VXR) or slot 7 (Cisco 7206 VXR), PCI bus mb0.

NPE-400, NPE-300, and NSE-1 Bandwidth Calculation and Configuration Instructions

Step 1 For the I/O controller and each port adapter in your system, check the footnotes in Tab le 1-6 to see if

any apply to your system.

Step 2 If you have any dual-wide port adapters in your system, carefully read the port adapter configuration

document to see what special conditions apply to these port adapters.

Step 3 Calculate the bandwidth points requirements. For the I/O controller and each port adapter in your

system, go to Table 1-6 and write down the bandwidth points requirements. Use the blank Bandwidth

Calculation Table, page 1-22, to record your requirements.

Step 4 Assign each port adapter in your system to a chassis slot.

• Make sure that the total bandwidth points for slots 0, 1, 3, and 5 (left bus) are less than or equal to

600.

• Make sure that the total bandwidth points for slots 2, 4, and 6 (right bus) are less than or equal to 600.

Step 5 Make sure that the bandwidth points are evenly distributed between the left (odd-numbered slots) and

right (even-numbered slots) buses. Include the I/O controller in your determination of balance for the left odd-numbered slots. Fill the slots in the following order: 2, 1, 4, 3, 6, 5.

Step 6 Check your Cisco IOS release and port adapter SDRAM memory requirements as detailed in Chapter 2.

You are finished calculating your port adapter configuration.

Note Dual-width port adapters occupy two horizontally aligned port adapter slots when installed in a

Cisco 7200 series router; however, dual-width port adapters do not use both PCI bus mb1 (left bus) and PCI bus mb2 (right bus) when operating in the router.

The dual-width PA-A2 port adapter uses only PCI bus mb2 (right bus) when installed in a Cisco 7200 series router.

The dual-width PA-12E/2FE port adapter autoselects PCI bus mb1 (left bus) or PCI bus mb2 (right bus) based on bandwidth availability—the port adapter selects the PCI bus that has the most available bandwidth. Therefore, do not include the bandwidth points for the PA-12E/2FE when calculating the combined bandwidth point total for a combination of installed port adapters in PCI bus mb1 (left bus) and PCI bus mb2 (right bus). Instead, add the bandwidth points for the PA-12E/2FE to the PCI bus that has the most PCI bus bandwidth availability (the PCI bus the PA-12E/2FE will autoselect) after completing the initial calculation.

Sample Bandwidth Configuration for the NPE-400, NPE-300, and NSE-1

This sample configuration is for a Cisco 7200 VXR chassis with an NPE-400 installed. The maximum points allowed for each PCI bus is 600 points. The I/O controller is considered a port adapter in bandwidth point calculation.

Installation Requirements Based on the NPE or NSE Installed

NPE-225, NPE-200, NPE-175, NPE-150, and NPE-100 Bandwidth Calculation and Configuration Instructions

Step 1 For the I/O controller and each port adapter in your system, check the footnotes in Tab le 1-6 to see if

any apply to your system.

Step 2 If you have any dual-width port adapters in your system, carefully read the port adapter configuration

document to see what special conditions apply to these port adapters.

Step 3 Calculate the bandwidth resource requirements. For the I/O controller and each port adapter in your

system, go to Table 1-6 and write down the bandwidth resource requirements. Use the blank Bandwidth

Calculation Table, page 1-22, to record your requirements.

a. High-bandwidth port adapter determination:

–

For the NPE-225, NPE-200, NPE-175, and NPE-150, make sure you have no more than three high-bandwidth port adapters.

–

For an NPE-100, make sure you have no more than two high-bandwidth port adapters.

b. High- and medium-bandwidth port adapter determination:

–

For the NPE-225, NPE-200, NPE-175, and NPE-150, make sure you have no more than five high- and medium-bandwidth port adapters.

–

For an NPE-100, make sure you have no more than four high- and medium-bandwidth port adapters.

Step 4 Calculate the bandwidth points requirements. For the I/O controller and each port adapter in your

system, go to Tab l e 1-6 and write down the bandwidth points requirements. Make sure the total number of bandwidth points is less than or equal to 800.

Step 5 Assign each port adapter in your system to a chassis slot. Make sure that the bandwidth points are evenly

distributed between the left (odd-numbered slots) and right (even-numbered slots) buses. Include the I/O controller in your determination of balance. Fill the slots in the following order: 2, 1, 4, 3, 6, 5.

Step 6 Check your Cisco IOS release and port adapter SDRAM memory requirements as detailed in Chapter 2,

“Memory Requirements.”

You are finished calculating your port adapter configuration.

Note Dual-width port adapters occupy two horizontally aligned port adapter slots when installed in a

Cisco 7200 series router; however, dual-width port adapters do not use both PCI bus mb1 (left bus) and PCI bus mb2 (right bus) when operating in the router.

The dual-width PA-A2 port adapter uses only PCI bus mb2 (right bus) when installed in a Cisco 7200 series router.

Chapter 1 Cisco 7200 Series Port Adapter Installation Requirements

Installation Requirements Based on the NPE or NSE Installed

Sample Bandwidth Configuration for the NPE-225, NPE-200, NPE-175, and NPE-150

The following sample configurations are for a Cisco 7200 series router with an I/O controller and NPE-225 installed. The maximum points allowed is 800 points per chassis.

The sample configuration in Tabl e 1- 4 follows the rule of keeping below the 800 maximum bandwidth points, and having no more than three high-bandwidth port adapters, and having no more than five highand medium-bandwidth port adapters in a chassis with an NPE-225. All three rules must be followed for a configuration to be valid. The I/O controller is considered a port adapter in point calculation.

The configuration in Tab l e 1- 5 is invalid because, although the bandwidth points are less than 800, there are four high-bandwidth port adapters installed, not three high-bandwidth port adapters as the rules allow. All three rules (no more than 800 bandwidth points, no more than three high-bandwidth port adapters, and no more than five high- and medium-bandwidth port adapters in a chassis with an NPE-225) must be followed for the configuration to be valid. The I/O controller is considered a port adapter in point calculation.

Chapter 1 Cisco 7200 Series Port Adapter Installation Requirements

Bandwidth and Bandwidth Point Requirements

Port adapters use various types of resources from the chassis and the NPE or NSE. Bandwidth is a term that describes port adapter resource requirements. Bandwidth includes variables such as speed, memory, CPU requirements, and PCI bus bandwidth. Because of changes in architecture in the network processing engines over the years, two methods were developed to describe port adapter bandwidth requirements. The methods are reflected in the Bandwidth Resource Requirement column and the Bandwidth Points column of Tab l e 1 - 6 . However, the information in these columns must be considered with the information in the following sections:

• NPE-G1 or NPE-G2 Bandwidth Calculation and Configuration Instructions, page 1-8

• NPE-G1 or NPE-G2 with a Port Adapter Jacket Card—Bandwidth Calculation and Configuration

Instructions, page 1-9

• NPE-400, NPE-300, and NSE-1 Bandwidth Calculation and Configuration Instructions, page 1-9

• NPE-225, NPE-200, NPE-175, NPE-150, and NPE-100 Bandwidth Calculation and Configuration

Instructions, page 1-11

Table 1-6 lists port adapter types, bandwidth resource requirements and bandwidth points, and processor

memory requirements.

Requirements Summary

This section provides a summary of bandwidth and bandwidth point requirements for each processing engine.

Port Adapter Jacket Card

PCI bus mb0 has a 600 point maximum. The Port Adapter Jacket Card accepts one port adapter which can use a maximum of 600 bandwidth points. PCI bus mb0 with a Port Adapter Jacket Card installed is designated as port adapter slot 5 in a Cisco 7204VXR router, or slot 7 in a Cisco 7206VXR router.

NPE-G1 or NPE-G2

• Left side, bus 1 (slots 1, 3, and 5) and I/O controller (slot 0) has a 600 point maximum.

• Right side, bus 2 (slots 2, 4, and 6) has a 600 point maximum.

• Distribute port adapter bandwidth points evenly across both left and right system slots (buses).

• Do not calculate bandwidth points for an I/O controller if an I/O controller is installed with the

NPE-G1 or NPE-G2.

• The NPE-G1 or NPE-G2 Gigabit Ethernet interfaces do not use bandwidth points.

NPE-400, NPE-300, NSE-1

• Left side, bus 1 (slots 1, 3, and 5) and I/O controller (slot 0) has a 600 point maximum.

• Right side, bus 2 (slots 2, 4, and 6) has a 600 point maximum.

• Distribute port adapter bandwidth points evenly across both left and right system slots (buses).

Note You can use a Cisco 7200 series router with a port adapter configuration that exceeds the preceding

guidelines; for example, if you have a redundant port adapter installed that is not in use. However, to prevent anomalies from occurring while the router is in use, we strongly recommend restricting the port adapter types installed in the router according to the guidelines listed above.

Additionally, your port adapter configuration must be within the above guidelines before the Cisco Technical Support Services will troubleshoot anomalies that are occurring in your Cisco 7200 series router.

1. Processor memory requirements are used when you determine port adapter installation guidelines for a Cisco 7200 series router.

2. Not applicable.

3. Bandwidth points for low-bandwidth port adapters are not required when you determine port adapter installation guidelines for a Cisco 7200 VXR router that has an NPE-400, NPE-300, or NSE-1 installed; that is, low bandwidth means 0 bandwidth points.

4. The PA-SRP-OC12 port adapters connect to both PCI buses; therefore, the total bandwidth points (300) are divided equally between the two buses. You must calculate the total bandwidth points by adding 150 bandwidth points to each bus.

5. When using only 1 port of the two ports available, the PA-2FE (TX) uses only 200 bandwidth points, and is an allowed usage. See also the “Messages

for One Port Use of Specific Port Adapters and an I/O Controller” section on page 1-22 for information on supported Cisco IOS releases and an error

message.

6. For use only in Cisco 7206 or Cisco 7206VXR router shelves in a Cisco AS5800 Universal Access Server.

7. The I/O controller with a Gigabit Ethernet port and an Ethernet port (C7200-I/O-GE+E) operates only in Cisco 7204VXR and Cisco 7206VXR chassis with the following network processing engines: NPE-400 and later network processing engines or the network services engine.

8. The I/O controller with two autosensing Fast Ethernet/Ethernet ports (C7200-I/O-2FE/E) operate only in Cisco 7204VXR and Cisco 7206VXR chassis and with the following network processing engines: NPE-225 and later network processing engines or the network services engine.

Question Answer

What determines the amount of SDRAM or DRAM memory required?

The DRAM or SDRAM required by a Cisco 7200 series router to support a combination of installed port adapter types and a Cisco IOS software subset image is influenced by such variables as the features in the software you plan to use and the size of your network.

Where can I find Cisco IOS memory requirements?

Cisco IOS memory requirements are listed in the Cisco IOS Release Notes. The SDRAM column provides processor memory information. Flash memory recommendations are also included. For Cisco IOS Release Notes, see the documentation page for Cisco IOS Software Configuration.

If you are a registered user on Cisco.com, you can access the Software Advisor at http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl to get memory requirements.

Chapter 2 Memory Requirements

Determining DRAM or SDRAM Required If the Router Has Only 32 MB of Memory (NPE-100, NPE-150, and NPE-200)

This section is applicable only to the NPE-100, NPE-150, and NPE-200.

To determine the minimum amount of DRAM or SDRAM required by a Cisco 7200 series router to support a combination of installed port adapter types and a Cisco IOS software subset image, complete the following steps only if your Cisco 7200 series router has 32 MB of DRAM or SDRAM.

If your Cisco 7200 series router has 64 MB or more of DRAM or SDRAM installed, you have enough memory to support any combination of installed port adapter types and Cisco IOS software subset images.

Note For Cisco 7206 and Cisco 7206VXR router shelf memory requirements, refer to the Cisco AS5800

Universal Access Server documentation at

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5800/index.htm.

Note The steps in this section assume that the port adapter hardware configuration of your Cisco 7200

series router follows the configuration guidelines explained in the “Configuration Guidelines and

Requirements” section on page 1-4.

If you need assistance when determining DRAM or SDRAM requirements for your Cisco 7200 series router, contact the Cisco Technical Assistance Center (TAC). See the “Obtaining Documentation,

Obtaining Support, and Security Guidelines” section on page vii for information on contacting TAC.

Tip Use the worksheets in the “Sample Configuration Showing Processor Memory Required” section on

page 2-2 to help calculate your system memory requirements if your router has 32 MB of memory.

Step 1 Add the processor memory requirements for all of the installed port adapter types and the Cisco IOS

software subset image. (See Table 1-6 in Chapter 1, and Ta b le 2- 5 through Tabl e 2 - 11 in this chapter.)

Table 1-6 lists the processor memory required for the port adapter types available for use in Cisco 7200

series routers. Port adapters available for use in Cisco 7200 series routers require a minimum amount of processor memory to function properly in the routers. The amount of processor memory required by a port adapter depends on the number of interfaces or channels the port adapter provides.

Note Some port adapters require additional processor memory to execute port adapter-specific

Cisco IOS software functionality. Table 1- 6 lists additional processor memory required for each port adapter type (where applicable).

For DRAM and Flash memory requirements for your Cisco IOS release and platform, see Cisco IOS Release Notes at Cisco IOS Software Information: http://www.cisco.com/univercd/cc/td/doc/product/software/index.htm.

The amount of processor memory listed in Tab le 2 -5 through Tabl e 2- 1 1 is for the static size of the image and some default data memory the image requires at system startup.

Chapter 2 Memory Requirements

SDRAM and DRAM Options for NPEs and the NSE

Step 2 Compare the required processor memory identified in Step 1 with the amount of processor memory

provided by each DRAM or SDRAM option listed in Ta ble 2-5 through Table 2-1 1 .

Table 2-5 through Tabl e 2- 1 1 list the processor and I/O memory provided by each DRAM or SDRAM

option available for Cisco 7200 series routers. The DRAM and SDRAM options available for Cisco 7200 series routers are logically divided into processor memory (which is used by the system CPU for instruction and data storage) and I/O memory (which is used for packet buffering). The amount of processor memory available for each DRAM or SDRAM option determines the combination of installed port adapter types that a Cisco 7200 series router can support.

Note For a DRAM or SDRAM option to support the installed port adapter types and Cisco IOS

software subset image, the required processor memory identified in Step 1 must not exceed the amount of processor memory provided by the DRAM or SDRAM options listed in

Table 2-7 through Table 2-1 1 .

Step 3 Choose a DRAM or SDRAM memory option.

This completes the procedure for determining the minimum amount of DRAM or SDRAM required by a Cisco 7200 series router to support a combination of installed port adapters and the Cisco IOS software subset image.

For a sample configuration of a Cisco 7206 router that has an installed NPE-150, an I/O controller with the Fast Ethernet port, and Cisco IOS software subset images for Cisco IOS Release 11.1CA and Cisco IOS Release 12.0T, see Table 2-2.

SDRAM and DRAM Options for NPEs and the NSE

The default memory allocation of total available memory between I/O memory and processor memory is 25% to I/O memory and 75% to processor memory. However, I/O memory may be allocated manually in amounts of 32 MB, 64 MB, 128 MB, or 256 MB, with the remainder going to processor memory.

Table 2-4 through Tabl e 2- 1 1 provide SDRAM and DRAM memory options for network processing

engines and the network services engine. Not all possible processor and I/O memory options are listed.
