Problem Description

The CISCO18XX & CISCO28XX Series hardware (listed in the Products Affected section) might fail to boot up after a user action where the board requires a power cycle operation.

Background

Cisco has been working with some customers on an issue related to memory components manufactured by a single supplier between 2005 and 2010. These memory components are widely used across the industry and are included in a number of Cisco products.

Although the majority of Cisco products using these components are experiencing field failure rates below expected levels, some components may fail earlier than anticipated. A handful of our customers have recently experienced a higher number of failures, leading us to change our approach to managing this issue.

While other vendors have chosen to address this issue in different ways, Cisco believes its approach is the best course of action for its customers. Despite the cost, we are demonstrating that we always make customer satisfaction a top priority. Customers can learn more about this topic at the Memory Component Issue web page.

A degraded component will not affect the ongoing operation of a device, but will be exposed by a subsequent power cycle event. This event will result in a hard failure of the device, which cannot be recovered by a reboot or additional power cycle. For these reasons, additional caution is recommended for operational activities requiring the simultaneous power cycling of multiple devices. This issue has been observed most commonly on devices that have been in service for 24 months or more.

Problem Symptom

If the CISCO18XX & CISCO28XX Series hardware (listed in the Products Affected section) has been in continuous operation for approximately 24 months, then the hardware might fail to boot up due to memory failure during a power cycle event. This is caused by one or more of these actions:

• Power cycle the entire product
• Power cycle after installation or Software Upgrade
• Manual or facility power interruption

Note: This issue does not affect boards while the boards are in operation. The board failure might occur after one or more of the actions listed are executed.

The problem symptoms include these memory failure messages that might be observed on suspect routers:

• Bad RAM
• SDRAM ECC Error

Workaround/Solution

For CISCO18XX Series hardware: Request Router RMA product through normal service channels.

For CISCO28XX Series hardware: Request Memory RMA through normal service channels (Memory module replacement only).

Please refer to this table for the appropriate Memory Product ID replacement:

NOTE: Routers may have multiple DIMMs. Please verify the individual DIMM slots using the command in the "How to Identify Affected Products" section of this Field Notice.

Please refer to the Installing and Removing DRAM DIMMs section of the Cisco 2800 Series Hardware Installation Guide in order to replace the Memory modules on CISCO28XX Series routers.

Normal SmartNet and warranty entitlement rules remain in place and are applied by the Cisco Technical Assistance Center (TAC) if you experience a failure in one of the products listed in the Field Notice. In other circumstances, such as out of warranty or out of contract, Cisco encourages you to raise your concern directly with your Cisco account team.

Fix on Failure Replacement Guidelines: Request Return Material Authorization (RMA) product through normal service support channels.

If you need assistance in order to determine which hardware part(s) might need replacement, consult the error messages documented in the Problem Symptom section.

How To Identify Affected Products

Enter the show platform command in order to obtain the size of the DIMM(s) of the router in question. If there is no DIMM in the second slot "Memory Slot Empty" will show in the output. Please see the output below as reference. If the CLI is not available, physically inspect in order to locate the PID.
