flashing and remains OFF when the IDU has rebooted. The traffic should return to normal very soon
thereafter.
In some cases the PC LAN card has to be reset (disable/enable) after the IDU reset in order to reconnect to
the LCT port. Do not pull the DC power while the IDU is resetting (MAINT led flashing).
Note. Ethernet settings restore (Partial Equipment Config) has the limitation that the source and target IDUs
have to be identically equipped. See also “Restoring Settings without a PC”.
PRECONFIGURATION FILES
Appendix D is a Quick Guide: how to install a new IDU when the common default settings have been
prepared in a reference IDU in advance. Most of the settings are copied to the new IDU using configuration
files.
If the IDU will use more cards than the reference IDU, these cards have to be physically removed before
copying the CFG-files to the IDU. The additional cards should then be reinserted and their settings done
manually as described in Appendix D and the rest of this document.
