Procedure how to replace npu1 b with npu1 c

  1. 1. PROCEDURE HOW TO Replace NPU1 B with NPU1 C MINI-LINK TN
  2. 2. Procedure How to replace NPU1 B with NPU1 C | eerwsum | 2015-05-07 | Page 2 background › Due to NPU1 B can not be ordered anymore and NPU1 C is the module that suitable and matched to replace NPU1 B. › Certain condition need to be fulfills before we are doing replacement of NPU1 B H/W with NPU1 C H/W. We need to do modification in old node Backup configuration using NPU1 B before we can use the old backup configuration in the node using a new hardware NPU1 C due both hardware have a different product number as below: NPU1 B ----------> ROJR 208 006/1 NPU1 C ----------> ROJR 208 011/1 Details Pre-requisites and Procedure you can find in the following slides. › NPU1 B & NPU1 C is only fitted with AMM 20p
  3. 3. Procedure How to replace NPU1 B with NPU1 C | eerwsum | 2015-05-07 | Page 3 Pre-requisites › Before doing replacement of NPU make sure ML-TN node already working under software baseline TN 4.4 FP2 (R22M10) or above or working with the latest software is preferable. › We should have the latest backup configuration for existing Node using NPU1 B in our folder: C:tn_ftp_hometn_backup_configuration › We should have a new NPU1 C H/W revision and naming convention board 1/11 type for NPU1 C. › Use the latest Mini-Link Craft Available in Software Gateway or at least use Mini-Link Craft 2.21. › A new module NPU1 C on the sub rack AMM should occupied a same slot as existing NPU1 B. › Another module should be remain in the same slot position before and after replacement NPU1 B to NPU1 C.
  4. 4. Procedure How to replace NPU1 B with NPU1 C | eerwsum | 2015-05-07 | Page 4 Procedure 1. Take a note Naming convention board 1/11 type for NPU1 B and NPU1 C : Naming convention for NPU1 B: board 1/11 type "ROJR 208 006/1" “XXX" "1“, where “XXX” is H/W revision NPU1 B (physical). Naming convention for NPU1 C: board 1/11 type "ROJR 208 011/1" “YYY" "16“, where “YYY” is H/W revision NPU1 C (Physical). 2. Do editing use notepad naming convention for NPU1 B become naming convention for NPU1 C inside the latest node backup configuration as below: board 1/11 type "ROJR 208 006/1" “XXX" "1“ board 1/11 type "ROJR 208 011/1" “YYY" "16“ Where “XXX” is H/W revision (physical) for existing NPU1 B and “YYY” is H/W revision (physical) for a new NPU1 C and saved it under: C:tn_ftp_hometn_backup_configuration
  5. 5. Procedure How to replace NPU1 B with NPU1 C | eerwsum | 2015-05-07 | Page 5 3. Turn OFF version control on the ML-TN node, so SBL will be N/A --> This is to avoid MLTN system reject new NPU's software that is not match with system software. 4. Replace NPU1 B with a new module NPU1 C. 5. Mini-Link TN will start up and goes into Installation Mode. 6. Select restoring configuration by download the configuration (download a changed backup configuration that we save it on the step no. 2). 7. Activate. 8. Now Mini-Link TN with a new NPU1 C module will start up and running as previous configuration. 9. Turn ON back version control by doing Software Baseline Upgrade suitable with Software Release NPU1 C newly installed, you can refer to Mini-Link TN Release Notes for this purpose. 10. End of Procedure.
