Cisco uBR10000 Series Universal Broadband Routers

Revised March 17, 2003

March 22, 2002

Products Affected

Problem Description

The original uBR10000 PRE does not accommodate planned, future Cisco IOS® Software feature sets that are necessary for forthcoming line cards due to lack of memory. If you upgrade to PRE-1, you can alleviate this issue. The uBR10000 chassis shipments that contained the PRE are eligible for a no-charge, proactive upgrade to the PRE-1.

Note:? The PRE-1 shipped on all new chassis since January 1, 2002, but some return materials authorizations (RMAs) were fulfilled with ESR-PRE=. When you are in doubt, check with the Cable Business Unit serviceability and design engineer to have the customer entitlement verified by the product marketing representative.

Background

The PRE-1 has memory size enhancements that allow for larger feature sets on follow-up products.

Problem Symptoms

The Cisco IOS Software image does not fit in RAM.

Workaround/Solution

There is no workaround. The solution for this issue is to upgrade the uBR10-PRE to ESR-PRE-1. Use the standard RMA process, as this upgrade is now service supported and the upgrade program has closed.

Note:?The uBR10012 chassis cannot operate with mixed PREs. Therefore, both the primary and secondary engine slots must be filled with the same engine. Make sure that you upgrade both engines to PRE-1 when you run secondary backup modes.

How To Identify Hardware Levels

The show version command identifies PRE and PRE-1 by name. You can use the show chassis command to verify the Top Level Assembly Part Number.

This is the output of the show version command from a PRE-RP:
