Post Change:

2.4.4 g) BDFBs/SPDUs shall be numbered from bottom to top, starting with “1.” On horizontal panels the count will start at the bottom left and go to right. Each fuse position shall be designated with its panel and fuse position number, e.g., 2.15 (fuse panel 2, fuse position 15). See AT&T Power Drawing – ATT-P-05400-E for specific BDFB/SPDU designation requirements.
Exception: When an SPDU/BDFB is provided as part of a turnkey solution and the SPDU/BDFB is dedicated to the turnkey solution it may follow the numbering convention assigned by the manufacturer.
In these instances, the SPDU/BDFB shall be stenciled as being dedicated to the specific piece of equipment and if entered into a capacity tracking system (ex. TabDb, Irma), notes shall be placed in the inventory system that the SPDU/BDFB is not available for assignment to any equipment other than the equipment for which it was installed.
