DIMETRA Express - Upgrading TSC B fails


Symptom(s)

Unable to program TSC B in a dual TSC MTS4 using both the available methods:-

a)export method (with the python script)

b) clicking on "program" button from DIMETRA Express WebNM

 

Issue

To verify:

1) Telnet to the TSC B

2) Inspect with software & firmware version by running this MMI command - .attrib

Note: When you run the python script (export method), it only detects TSC A ip addressing segment regardless the TSC status (either Active or Standby)

Environment

DIMETRA Express

R2.4SER & R2.5

 

Resolution

Fix available in DIMETRA Express R2.6

Workaround to program TSC B:

  • Get the python script from DEX WebNM (by clicking on export button)
  • Unzip the file (contains the python script - program_site.bat), and connect the laptop (that has this file), to TSC A service port.
  • Program TSC A first (by running this file - program_site.bat)
  • Once the TSC A is completed, power off TSC A but leave the BRs (BR1,BR2,etc) powered on (i.e. only remove the power cable from the TSC A itself and not using the power on/off button on the power supply). Please refer to the image below.

  • Disconnect the laptop from TSC A service port.
  • Reconfigure the IP address of the laptop running the programming script to 10.0.254.100 segment.
  • Connect to TSC B service port and rerun the program_site.bat. Note: There will be a “ping 10.0.253.1” ping timeout warning shown on the command prompt window, but that can be ignored)
  • The site will go LST (local site trunking) mode.
  • And TSC B will reboot once the program is complete. And now TSC B will hold the active status. 
  • Turn off TSC B.
  • Connect back the power cable in TSC A. And you'll noticed TSC A has active status.
  • Power off the MTS completely.
  • Connect back the power to TSC B. 
  • Power up the MTS. 
  • Finally, inspect the software & firmware version in both the TSCs (A&B).
