Preliminary Preparations
The installation procedures provided in this chapter assume that:
| The sites at which the installation procedures are carried out comply with
the requirements listed in Site Preparation (on page 2-4 ).
| The preliminary preparations specified in Before You Start (on page 2-1 )
have been completed.
Before you start, determine what equipment is to be installed in the rack by
referring to the site installation plan, and note the exact position of each unit (to
avoid errors, it is recommended that you mark the prescribed positions on the
rack rails using a soft pencil).
Equipment Installation Sequence
Each component of the XDM-300 system is supplied separately and must be
installed in the correct sequence, according to the site plan.
The XDM-300 shelf can be mounted in the rack in an horizontal or vertical
position. The main equipment used for both installations is similar, and differs
in the number of accessories, type of brackets used in each position, and one
accessory, used only for horizontal mountings.

OTE
:

If you are not installing an FST for a particular XDM-300
shelf, it is recommended that you leave empty space in the
rack in case optical modules are added to the shelf in the
future.

If you are not installing a TPU for a particular XDM-300
shelf, it is recommended that you leave empty space in the
rack so that the protection unit can be added in the future,
if required, without interrupting operation.
C
AUTION
:

If additional equipment is used in the rack, a heat buffer or
a buffer plate must be installed between any such
additional equipment and the XDM-300 shelf to minimize
the transfer of heat from shelf to shelf. This heat buffer
must be purchased from ECI Telecom.

During the installation of equipment in the rack, make
sure all the optical connectors are closed by protective
caps. Do not remove the cap until an optical fiber is
connected to the corresponding connector.
Several installation options are illustrated in Installation Options (on page
3-10 ).
