[Problem Summary] On NE40E CFCard TDK 2GB (BOM_02310MDH) is not recognized/fails by NE40E CR52SRUA1 (BOM_03030GED)
[Problem Details] NE40E-8 routers can not recognize CFcards (TDK CompactFlash 2GB CFG8B02GVBZWS-ZAVEB http://product.tdk.com/en/catalog/datasheets/ew_014_cfg8b.pdf) or check fail after startup.

 

[Alarm information] 

Dec 23 2014 00:50:28 RT-A-1 SRM_BASE/1/ENTITYINVALID: OID 1.3.6.1.4.1.2011.5.25.129.2.1.9 Physical entity failed.

Dec 23 2014 00:50:28 RT-A-1 SRM_BASE/1/ENTITYINVALID: OID 1.3.6.1.4.1.2011.5.25.129.2.1.9 Physical entity failed. (EntityPhysicalIndex=17432578, BaseTrapSeverity=5, BaseTrapProbableCause=67976, BaseTrapEventType=5, EntPhysicalContainedIn=17432577, EntPhysicalName="CR52SRUA 10", RelativeResource="", ReasonDescription="MPU 10 is failed, cfcard2 status check fail")

Handling Process

1. CF card was re-formatted and software written by USB-card-reader.

Router can not recognize CFcard on startup

 Problem phenomenon description can be found on Internet “Partition alignment”. TDK CF card need to be formatted with FAT16 (32KB) and partition aligned to 1MB barrier (2048 sector). After it NE40E v3r6 can normally recognize this CFcard and it’s content.

 

 

2.  After SRU/MPU board completely loaded following alarm appear:

2      Alert      14-12-23  02:08:29    MPU9 is failed, both cfcard and cfcard
                                        2 status check fail [BasCode:0x10988,E
                                        ntCode:0x2041a]
3      Alert      14-12-23  02:08:57    MPU10 is failed, both cfcard and cfcar
                                        d2 status check fail [BasCode:0x10988,
                                        EntCode:0x2041a]

Delete partition on CFcard and Create partition again as shown on Picture:

Root Cause

  There is a  difference of FAT16 and Physical Drive Geometry for TDK_factory made and TDK_re-partitioned(with USB-cardreader on Windows7).
TDK_factory partition is FAT(LBA)

TDK__re-partitioned partition is FAT(big)

 TDK_factory_partition FAT(LBA)  TDK_re-partitioned_partition FAT(big) on Windows7
   

Solution
New CF cards need to be re-partitioned (Primary,FAT16, Align to cylinder) before use on NE40E router.
