Board Renumbering with the 016 MLX Module
8-78
Installation, SPM, Maintenance, and Troubleshooting Supplement
Follow these steps to replace a 008 MLX module with a 016 MLX module:
1. Back up the system programming to the customer backup card. Use a
filename that describes the pre-016 MLX configuration-for example, “pre-
016 MLX.”
2. Print a System Setup report. Determine whether the last slot/slots are
programmed with phantom modules. If there are phantom modules, the
programming for these modules will be removed when the new 016 MLX
module is implemented.
3. If no phantom modules are programmed, go to Step 4. If there are phantom
modules, print out all the Extension Information reports for the extensions
and MFMs connected to the phantom modules. The extensions must be re-
programmed after the module is implemented.
4. Print an Extension Directory report. (This report also includes phantom
extension numbers.)
5. Print a Group Calling Information report.
6. Print a Group Coverage Information report.
7. Print Extension Information reports for all ports (including MFMs) on the
008 MLX module that is being replaced.
8. Power down the system and replace the 008 MLX module with the 016
MLX module.
9. Power up the system.
This procedure adds eight additional logical IDs to the system
configuration, starting after the first eight ports of the new 016 MLX
module. (This occurs because you are adding eight ports to the
system for each 016 MLX module that replaces a 008 MLX module.)
The second set of eight ports on the 016 MLX module will acquire the
extension numbers from the next extension module to the right in the
system. This slippage continues for the rest of the extension modules
in the system. You must do extensive station renumbering for the
extensions that follow the new 016 MLX module.
