Introduction

This document describes how to distinguish one Route Processor Module (RPM) from another. The RPM for the Cisco MGX 8800, 8230, and 8250 series products has undergone several revisions, which can cause confusion when you need to distinguish one from another. You must be able to identify differences between the three generations of RPMs in order to process a return material authorization (RMA) order.

Prerequisites

Requirements

Readers of this document should be knowledgeable of:

• Cisco MGX 8800, 8230, and 8250 series products hardware

• Cisco IOS^® software command line interface (CLI)

Components Used

This document is not restricted to specific software and hardware versions.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

For more information on document conventions, refer to the Cisco Technical Tips Conventions.

Inspect the Board to Determine the RPM Type

This table provides the product name, key components, and changes in each generation of the three types of generally available RPMs.

Note: In this table, X is a variable that represents the hardware version.

Note: SAR = segmentation and reassembly

For additional information about enhancements to the RPM/B and minimum firmware and IOS requirements, refer to Product Bulletin, No. 984. RPM-PRs do not work with the MGX-RJ45-4E. RPM-PRs require a MGX-RJ45-4E/B. The MGX-RJ45-4E/B works with the RPM/B and RPM-PR.

It is important to note that the front faceplate of the RPM labels are not always correct. Listed here are various RPM faceplate labels and what they can mean:

Characteristics of the RPM (RPM/A)

You can identify an RPM by the module's ATMizer chip. Look at the top of the card (when the card is held upright) for the column identifier L. In the example provided, the identifiers are two ATMizer chips from LSI. The original RPM has a chip labeled ATMizer-LX60. The chips below these (in an L formation) have a logo from Digital on them. The chips in the L formation are indicated by circles in this picture:

Characteristics of the RPM/B

You also can identify an RPM/B by the module's ATMizer chip. Look at the top of the card (when the card is held upright) for the column identifier L. Below the identifier are two ATMizer chips from LSI. The RPM/B has a chip labeled ATMizer II+. The first line of small print text identifies this as an ATMizer-LX80. The chips below these (in a L formation) have a logo from Intel on them.

Characteristics of the RPM-PR (RPM-400)

You can identify an RPM-PR by the additional casing over the board. The chips and control board are not visible.

Characteristics of the RPM-XF

You can identify an RPM-XF by the additional casing over the label on the board. The chips and control board are not visible.

Use the CLI to Determine the RPM Type

You can use these Cisco IOS software commands at the RPM command line interface (CLI) to determine the amount of Flash memory installed, which can help you identify which RPM you have:

• show version

• show flash

• dir (Privileged EXEC mode. You must first type enable at the > prompt.)

After you determine the amount of Flash memory, use this table to find out the RPM type:

Use the show version Command

Example 1:

In this example, note the line second from the bottom. This line shows the amount of Flash memory. In this case, there is 16384 KB, which equals 16 MB. The amount of memory makes this an RPM/B.

Example 2:

In this example, note the first line in the fourth paragraph—this line indicates that this is an RPM-PR card. Cisco has two varieties of RPM-PR cards; one is with 256 DRAM, and the other is with 512 DRAM. To differentiate between 256 or 512 DRAM, look at the second line of the last paragraph, which shows the flash memory and sector size. If the sector size is 256, this indicates a 256 DRAM.

Use the show flash Command

In this example, note the last line, which shows the amount of available Flash memory and the amount that is used. Add the two amounts to determine the total installed. In this case, 959004 bytes plus 2448868 bytes equals 3407872 bytes. This is approximately 4 MB, which makes this an RPM (RPM/A) card.

Use the dir Command

In this example, note the last line, which shows the total amount of available Flash memory and the amount that is in use. There are 32768000 bytes, which is 32 MB, and makes this an RPM-PR (RPM-400).
