Installing Unit Components in Cabinet
Unit components here indicate the S2SC70
-F, SSC60
-F, SSC50
, SSC57
and SNB10D
node units and SNT10D unit for optical bus repeater modules. When installing these unit
components in a cabinet, dummy plates may have to be installed and a gasket may have to be
attached to the dummy plates in the following cases:
• There is a large space between unit components.
• There is no space between unit components.
• Unit components are installed unevenly inside the cabinet.

hen Leaving a Large Space between Unit Components
When leaving a large space between unit components, install the following dummy plates to
board up the spaces. A UNIT equals 44.45 mm high. Depending on the location of the dummy
plate, attach an EMI shielding gasket to the dummy plate.

Specification of EMI shielding gasket: Width 5 mm, Thickness 1 mm
Location to attach EMI shielding gasket:
Attach an EMI shielding gasket onto the bottom surface of the lower bend of a dummy plate as
shown below. Where a unit component is installed immediately above a dummy plate, attach an
EMI shielding gasket also onto the top surface of the upper bend of the plate. However, for the
dummy plate installed at the bottom of the component mounting area, no EMI shielding gasket
needs to be attached onto its lower bend.
Where a unit component is installed immediately
above a dummy plate, attach an EMI shielding gasket
also onto the top surface of the upper bend of the plate.
