Installing Ancillary Units in Racks
ECI offers various accessories for efficient and optimal installation in racks. Contact ECI’s Customer Support
team or your ECI sales representative for additional items or custom modifications to standard items.
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
FST: Located under the NPT-1020 platform, recommended for installations with a large number of

Installing the Fiber Storage Tray
xDDF-21: This unit must be installed for unbalanced E1 interfaces. See
AC_CONV_UNIT: This unit is an AC power platform that can be mounted separately on the rack. 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.
