Installing, Optical, CWDM, and Electrical I/O
Modules
The following procedure can also be used to replace cards and modules in an
operating shelf, provided the general safety precautions listed in Work and
Equipment Safety (on page
2-20 ) and the module-specific warnings listed in
the XDM-100 Product Line Reference Manual for each module are strictly
followed. Before starting, make sure that all the I/O modules specified for
installation in the XDM-300 shelf in accordance with the shelf installation plan
are available.
All I/O modules are installed in slots I1 through I16, as shown in the following
figure. In addition, if I/O cards are not installed in the wide slots (I17, I18), a
SIM16_1 module can be installed in each of these positions by adding a
mechanical adapter. This section describes the installation of the electrical,
optical, and CWDM I/O modules, which are single-slot modules. The
installation of PIM2_63/B and MCSMs, which are double-slot modules, is
described in Installing Double-Slot Modules (on page
3-67 ).
In general, to facilitate easy cable routing, it is preferable to install all electrical
modules on the one side of the XDM-300 shelf (left or right), and all optical
and CWDM modules on the other side.
If you are employing a TPU 1:1 protection scheme, electrical modules that
have TPU protection should be arranged in pairs, one below the other. For 1:2
and 1:3 protection schemes, it is recommended that all electrical I/O modules
be installed on one side of the XDM-300 shelf, in slots I1, I2, I5, and I6, or in
slots I3, I4, I7, and I8 in the upper module cage, and I9, I10, I13, and I14, or in
slots I11, I12, I15, and I16 in the lower module cage.

When installing optical modules, make sure all SFP
transceiver slots are closed by protective caps. Do not
remove the cover until an SFP is inserted.

For your safety, to comply with electro-magnetic
compatibility (EMC) requirements and to prevent escape
of ventilation from the fans through these openings,
protect all unused slots with blank panels.
