NPT-1020 Installation and Maintenance Manual
To ground the NPT-1020 shelf:
NPT-1020 shelf grounding is achieved by connecting the shelf to the rack using rack mounting

brackets. Grounding is provided by contact when the unit is fastened to the rack.

4.7.4 Installing Power Modules in the NPT-1020

Each NPT-1020 shelf must have a power module/modules installed in the power module slot(s). The power
module slots are identifies as PSA and PSB. There are several options to install power modules in these slots
as follows:
Installing an INF-B1U in slot PSA and a second one in slot PSB. This configuration supports DC power

redundancy for the NPT-1020 by connecting each module to a separate power source.
Installing an INF-B1U-24V in slot PSA and a second one in slot PSB. This configuration supports DC

power redundancy for the NPT-1020 by connecting each module to a separate power source.
Installing one INF-B1U-D module. This module occupies both PAS and PSB slots. DC power

redundancy is supported by connecting each input power connector on the INF-B1U-D to a separate
source.
Installing one AC_PS-B1U module. This module occupies both PAS and PSB slots and provides AC input

power support.
The following sections describe the installation procedures for each of the options.
The NPT-1020 is always shipped with power module/modules installed. The procedure described in this
section is therefore only relevant when you want to replace the power module.
4.7.4.1 Installing an INF-B1U
For DC power redundancy, the NPT-1020 platform must have two INF-1BU modules installed in the power
module slots, and is always shipped with power modules already installed. The following procedure
therefore describes replacing the power module.
