Board Renumbering with the 016 MLX Module

System Programming Maintenance
10. Perform a Board Renumber procedure: Sys Program ()→
System ()→Board Renum ()→Yes ().
11. Print a new Extension Directory report.
12. Extension numbers from the module immediately to the right of the 016 
MLX module have migrated to the top eight ports of the 016 MLX module. 
Renumber these ports to unused extensions. This releases the migrated 
extensions to be moved back into their original slot/ports.
13. Using the Extension Directory report that was printed in Step 4, renumber 
the extensions back to their original ports. Start the renumbering with the 
first module after the 016 MLX module. Use the eight extensions that were 
released in Step 12. These extensions are the extensions originally located 
on the first eight ports of the module after the replaced module. Use 
individual or block renumber as needed to perform this operation.
14. Continue to renumber the rest of the extensions back to their original ports 
until you reach the end of the system.
15. Print a Group Calling Information report, and compare it to the Group 
Calling Information report you printed in Step 5. Since Calling Group 
extensions may reverse themselves after a Board Renumber, verify that the 
extension numbers are in the correct order. If the extensions are reversed, 
re-program as necessary to put in correct order.
16. Verify the programming on the first eight ports of the 016 MLX module. Use 
the Extension Information reports that were printed in Step 7.
17. Print a new Group Coverage Information report and compare it to the 
previous Group Coverage Information report. Verify that the appropriate 
members are in the group. Program as necessary to match the previously 
printed report.
18. If additional 016 MLX modules are to be added, repeat ALL of the above 
steps for each module. If not, go to Step 19.
Remember that the extension numbers have increased by eight, 
beginning after the first eight extension numbers on the 016 MLX 
module.
