Installation of Plug-in Modules
HPS power supply plug-in modules can be installed by pushing the release button of the module handle down and simultaneously pulling the top of the handle forwards.
Align the module so that the PCB slides into the “crow’s feet” with the module upright and perpendicular to the front face of the rack. Gently push the module down its
guide, applying pressure via the handle and the outmost curved face (do not apply pressure to the ventilation grill). As the module is fully mated the top of the handle
should snap back and lock in position. Addition resistance will be experienced as the low resistance backplane connector engages. The pawls of the handle should be
fully engaged in the matching slots. To disconnect the module, push the release button of the module handle down and simultaneously pull the top of the handle
forwards. Apply pressure via the handle and withdraw the module from the rack.
Blind mate modules can be installed by pushing the release button of the module handle down and simultaneously pulling the top of the handle forwards. Remove the
protective cover from the modules optical connectors. Clean the module optical connector. Align the module so that the PCB
slides into the “crow’s feet” with the module
upright and perpendicular to the front face of the rack. Gently push the module down its guide, applying pressure via the handle, as the module is fully mated the top of
the handle should snap back and lock in position. The pawls of the handle should be fully engaged in the matching slots. To disconnect a module, push the release
button of the module handle down and simultaneously pull the top of the handle forwards. Applying pressure via the handle and gently withdraw the module from the
rack, replace the protective covers on the optical connectors.
Standard and controller modules can be installed by pushing the release button of the module handle down and simultaneously pulling the top of the handle forwards.
While installing the protective covers may be left in place on RF a
nd optical connectors. Align the module so that the PCB slides into the “crow’s feet” with the module
upright and perpendicular to the front face of the rack. Gently push the module down its guide, applying pressure via the handle, as the module is fully mated the top of
the handle should snap back and lock in position. The pawls of the handle should be fully engaged in the matching slots. To disconnect a module, remove any cables
you do not want to withdraw, push the release button of the module handle down and simultaneously pull the top of the handle forwards. Applying pressure via the
handle and gently withdraw the module from the rack, replace the connector protective covers.
All
ViaLiteHD
plug-in modules are hot-swappable, so it is not necessary to power-down the rack case before inserting a module. It is advised that all unused slots be
fitted with blanking panels. Different width blanking panels are available; these fit the 5HP general purpose, 6HP power supply, 7HP controller card slots. They can be
used in all
ViaLiteHD
racks cases and will prevent accidental/unwanted access and the ingress of dust.
When operating RF fibre optic links the ideal operating input power is dependent on the end users system. However in all cases there will be the desire to achieve the
optimal signal quality (ratio of signal to noise plus distortion). At low signal power this will be dominated by thermal noise and at high signal powers it will be dominated
by distortion products. Typically a good quality signal can be obtained by operating the link at a composite input power 20d
B below the fibre optic module’s P1dB
specification level (see handbooks).
The backplane has data connectors for module positions 1-13; this provides access to module data. The pin-outs of these connectors are given in the following section
