  • Part Description: Backplane LR018-B/
Part
  • Part No: 1507203-A
  • Part Description: Backplane LR018-A/

Impact

Previous DKU backplane cooling FAN circuitry was controlled only from the right side FSW (FSWxxx-Rx).

In newly released DKU configurations, a left side FSW (FSWxxx-Lx) may be mounted without right side FSW (FSWxxx-Rx).

If a DKU is operated without the proper support for single side FSW DKU configuration, the DKU FANs do not rotate and the DKU will overheat.


Resolution

FSW (FSWxxx-Rx) is required on the right hand side of array frame when:

1. Older DKU backplanes(revision less than LR018-A/5G) are installed.

or

2. If microcode cannot be upgraded to 50-03-9X-00/00 or above on DKUs with newer backplanes LR018-A/5G or 1507844-B LR018-B/5F(or higher revision) installed, and no FSW(FSWxxx-Rx)exists on the right side on the array frame.

 

The following configuration rules are provided to assist in proper configuration planning:

  • Old backplane versions PN 1507203-A with part name and revision less than LR018-A/5G do not allow for single FSW support.
  • New backplane P/N 1507203-A LR018-A/5G (or higher revision) or 1507844-B LR018-B/5F (or higher revision) are the new modified versions allowing for single FSW support.
  • V03 microcode 50-03-9X-00/00 or higher is required when installing HDDs and FSWA on only the left side of DKU. There is no microcode prerequisite in configurations with both left and right FSWs installed.
  • The new backplanes are contained in array frames with product code DKU505I-18A and DKU505I-18R, the old product code was DKU505I-18.
  • All RoHS compliant Array Frames will contain modified backplanes but with a different part number 1507844-B and the part name/revision will be LR018-B/5F or higher.
  • The new Array Frame, DKU505I-18A and the old frame DKU505I-18 may be intermixed within SE9990 subsystems.

 

New single side capable DKU frame serial numbers:

Non-RoHS compliant Array Frames (DKU505I-18A)

100526 - 100529 array frame may not be labeled as DKU505I-18A

100531 - 100542 array frame may not be labeled as DKU505I-18A

150001 - 199999 array frame will be labeled as DKU505I-18A

350001 - 399999 array frame will be labeled as DKU505I-18A

450001 - 499999 array frame will be labeled as DKU505I-18A

 

RoHS compliant Array Frame Serial Numbers (DKU505I-18R)

200001 - 299999 array frame will be labeled as DKU505I-18R

600001 - 699999 array frame will be labeled as DKU505I-18R

800001 - 899999 array frame will be labeled as DKU505I-18R
