Installing the NPT-1020 Shelf in the Rack
Each NPT-1020 shelf is supplied with an installed power module and an empty Dslot (covered by a blank
panel). Therefore, the installation activities covered in this section include:
Installing the Rail Stiffeners
Attaching the NPT-1020 Shelf in the Rack
After the activities presented in this section have been completed, the NPT-1020 shelf is ready for:
Installing Power Modules in the NPT-1020
Installing SFP Modules

Installing the Rail Stiffeners
If you install the NPT-1020 in the rack without installing rail stiffeners, the rear side of the NPT-1020 shelf
will be slightly lower than the front side, due to the weight of the NPT-1020 shelf. This makes installation of
the EXT-2U very difficult. The rail stiffeners make the NPT-1020 level after it is installed in the rack. Two rail
stiffeners are shipped along with the NPT-1020 shelf.
