Migrate SX-2000 PBX Hardware
Only the MicroLight can be migrated using this procedure. To migrate an
SX-2000 Light Non-redundant system simply replace the control cabinet
with a 3300 controller.
To upgrade SX-2000 MicroLIGHT hardware for 3300 ICP control:
1. Remove the Main Controller (MMC) from slot 1/1/1.
2. Install a triple FIM in that slot.
3. Remove any FIM carrier cards in the DSU slots.
4. Do NOT remove any other cards.
An SX-2000 MicroLIGHT system converted to 3300 control uses fiber
interface modules (FIM) of the triple FIM carrier card as required:
• One triple FIM carrier card
• One control resources card
• One peripheral switch control (PSC) Card
• One to eight peripheral interface cards (PIC)
• Optionally, one to four DSU cards 0 DSU1 through DSU4.
Any DSU or peripheral cabinets that were connected to the MicroLIGHT,
must now be connected by fiber directly to the 3300 ICP controller.
Tip: Refer to Knowledge Base Article 04-1000-00068 (TB 58005193) for
Migration procedure details.
