The specific units you need to install depend on your site installation plan and may include one or more of
the following:
RAP unit: For connecting up to four or eight NPT-1020 platforms (NPT-1020 with EXT-2U is counted as

two platforms) on the same rack, usually located at the top. See
the RAP-4B.


optical modules. See

In general, ancillary units are attached to the rack side rails by four M6 Phillips screws. No preparation is
required before installation. The following sections provide mechanical installation instructions for units
that require additional procedures. Skip sections that are not relevant to your particular application.

AUTION: If additional equipment (other than NPT-1020 platforms) is installed in the rack, a
heat buffer must be installed between such equipment and the NPT-1020 to minimize the
transfer of heat from platform to platform. Consult your ECI representative regarding the
exact heat buffer required.
