Compatibility Issue

It is important for customers to understand the compatibility issues between FTA/FTF and FTA2/FTF2 and the NEBS3 shelf assembly and the NEBS3E shelf assembly (Table 2).

The new shelf assembly (15454-SA-NEBS3E) offers cosmetic changes, including branding/name changes, as well as fiber management enhancements. The fiber management enhancements include reels on the side of the cabinet for storing excess fiber jumper slack and a fan tray that can be removed for maintenance and filter replacement without disturbing the fiber management on the front of the shelf. These are the major differences between the two shelf assemblies. Other changes are minor in nature (Table 3).

Part Description


The new fan tray assembly (15454-FTA2) is not a replacement or interchangeable with the EOL 15454-FTA fan tray assembly. The 15454-FTA2 will not install into the old 15454-NEBS3 shelf assembly.



The new fan tray filter (15454-FTF2) is backward compatible with the previous fan tray filter (15454-FTF) and the previous shelf assembly (15454-NEBS3). However, the 15454-FTF only installs in the discontinued 15454-NEBS3 shelf assembly with the 15454-FTA fan tray assembly.
