Products Affected

Problem Description

A production shortage of boot flash memory components has forced the substitution of an alternate boot flash component on the C7200-I/O, C7200-I/O-FE, UBR7200-I/O, and UBR7200-I/O-FE controllers. The I/O controllers built with this boot flash component fail to boot with NPE-100, NPE-150, and NPE-200 processors.

Other 7200 processors, NPE-175, NPE-225, NPE-300, NPE-400, and NSE-1 are not affected by the flash component substitution.

Existing C7200-I/O controllers containing the original boot flash components are not affected.

Background

Problem Symptoms

If boot-up on a 7200 system containing an NPE-100, NPE-150, or NPE-200 and the affected C7200-I/O-xx controller is attempted, the following error messages will be seen:

For the NPE-150 (dir bootflash):

Workaround/Solution

If a customer has a C7200-I/O-xx controller marked with the Deviation label D001870 and wishes to use the I/O controller in a 7200 system with an NPE-100 or NPE-150, they will need to obtain an upgraded I/O controller.

If a customer has a C7200-I/O controller with the Deviation label D001870 and wishes to use the I/O controller in a 7200 system with an NPE-200 card, they will need to obtain an upgraded NPE-200.

If a customer has a C7200-I/O-xx controller marked with the Deviation label D002122 and wishes to use the I/O controller in a 7200 system with and NPE-200, they will need to obtain an upgraded NPE-200.

Replacement hardware should be obtained through the regular RMA process.

The table below details the behavior encountered when matching affected I/O controllers with different NPE units.
