Revision Date Comment 1.0 12-DEC-2012 Initial Public Release
Products Affected UCSC-C220-M3L UCSC-C220-M3L=
Component leads protruding from the hard disk drive backplane may short against the hard disk drive stopper if it becomes bent due to excessive force. The shorted leads may cause component damage, unexpected system shutdown, or possible thermal event. Hardware replacement is highly recommended.
A UCS C220 M3 LFF unit failed during Manufacturing Final System Test (FST) due to fuse leads from the hard disk backplane coming into contact with a bent/misaligned hard disk drive stopper on the chassis. The bent stopper allowed hard disk insertion force to push it through the protective Mylar cover and cause a short against fuse leads. The short caused a brief thermal event of less than one second and subsequent power supply shutdown. There has been a single occurrence of this issue in the factory, and there have been no occurrences in the field.
Analysis of the test failure has concluded that this failure can only occur when the hard disk drive stopper becomes bent out of specification, and a user attempts to install a hard disk drive. Rework and revision to the hard disk backplane shortens the extended fuse leads to prevent protrusion through the protective Mylar over the backplane. An additional test has been added to the manufacturing process to confirm correct alignment of the hard disk drive carrier.
If the hard disk drive stopper becomes bent, forcible insertion of a hard disk drive assembly into any slot with the bent carrier may cause power supply failure due to overcurrent event and immediate ungraceful shutdown.
Cisco recommends replacement of the chassis assembly with a new chassis containing revision 02 hard disk backplane. A replacement chassis will be provided at no extra charge. A Cisco Field Engineer will also be scheduled at no charge in order to move customer-ordered options to the replacement server. Please use the order form in the Upgrade Program section below to order your replacement UCS C220 M3 LFF chassis. Serial number(s) of your original chassis are required. Serial numbers are not required for thermal grease, cleaning kits, or pick and place tools. These are additional items used during chassis replacement activity.
- For each UCS C220 M3 LFF chassis, one CPU cleaning kit and one Thermal Grease kit should also be ordered.
- For each customer installation site, one CPU Pick and Place tool should be ordered.
- After you receive your replacement hardware, contact Cisco TAC in order to schedule a Field Engineer. Refer to: http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html
How To Identify Hardware Levels
UCS C220 M3 LFF chassis with updated hard disk backplanes can be identified by one of the following methods:
- Deviation label on the chassis exterior and packaging with the number: D130065
- The Cisco Part Number revision on the chassis label reads 74-9933-02 or higher.
Deviation D130065 has been applied at the factory for rework to in-house units.
