||There were no defects filed with this field notice at the time of publication.|
Cisco has determined that the RAID controller Battery Backup Unit (BBU) in the Cisco FS3500 Series and SourceFire DC3500 Series management appliances might be subject to a higher than expected failure rate.
Cisco has determined that the affected products shipped between June 2011 and November 2014 might be susceptible to premature failure. The failure rate of the BBU has been observed to be 5% to 10% within the first two years of system operation. The higher failure rate is due to certain characteristics of the lithium ion battery technology.
A redesigned BBU that uses lithium polymer battery technology is now available, which greatly improves the reliability of the BBU and expands the battery life to approximately five years.
For Cisco FS3500 Series and SourceFire DC3500 Series management appliances that run software Version 5.2 or later, a failure of the RAID controller BBU appears as a yellow health alert warning on the console, along with this message output:
1 RAID Adapters checked. 1 RAID Logical drives checked. 4 RAID physical drives checked. sda status: OK. RAID Cache Policy is degraded.
For Cisco FS3500 Series and SourceFire DC3500 Series management appliances that run software versions earlier than Version 5.2, no health warning message appears on the console.
In addition, if the configuration or use of the Cisco FS3500 Series and SourceFire DC3500 Series management appliances require high disk drive usage, a performance degradation and/or failure of the user interface might be experienced as a result of slower file input/output operations.
Request an RMA for the RAID controller BBU upgrade kit (FS3500-BBU-KIT=) through your normal support process for Fix on Failure.
Note: Refer to the Replacing the RAID Battery Backup Unit Assembly on Series 3 FireSIGHT 3500 Defense Centers, Version 5.x document in order to review the upgrade instructions.
Cisco FS3500 Series and SourceFire DC3500 Series products manufactured after November 11, 2014 are free of this issue. Refer to the How to Identify Hardware Levels section of this document for instructions on how to view the current product version.
