4 IHU INSTALLATION
This chapter describes the installation for the IHU, PSU-6, and MRU equipment. A section is dedicated to general information
relevant for the installation of the HEU, OIU and IHU, followed by dedicated installation sections for each type of equipment.
Note: For specific guidelines on infrastructure planning, design and installation, please consult with a Corning product line
manager or Corning approved installer.
4.1 General Installation Information
Note the following information:
The IHU chassis and modules are supplied separately and must be inserted by the user. Only the fan module is factory
installed in the chassis rear.
The IHU is installed at the intermediate distribution frame (IDF), adjacent (or as close as possible) to each other to facilitate
the connections.
The expander cable (ERFC) interconnecting the OIX and RIX modules are provided in lengths ranging from 16 to 59 in so as
to accommodate a range of HEU-OIU rack installation configurations.
HCMs and ACMs are not hot-swappable.
Hot-swappable modules: RIMs, OIMs, PSMs, FAMs, RIXs and OIXs.
If a redundant power supply is provided, both supplies must be installed, connected to respective AC or DC power and
switched on.
All components of a system installation are controlled and managed via a single HCM which is installed in the IHU chassis.
Note: The management connections for the Corning
optical network evolution (ONE
) solution elements are detailed in the
HCM and Web management GUI user manual.
