Eclipse Installation Manual
NPC Only one NPC is required to provide the NCC protection
option. An NPC must be installed in slot 4 of an INU, or slot
10 of an INUe. If an NPC is not installed in an INU, slot 4 is
available as a universal slot.
Installing / Changing Plug-ins
ESD grounding strap Always connect yourself to the INU/INUe with an ESD
grounding strap before changing or removing a plug-in.
Failure to do so can cause ESD damage to the plug-ins.
Avoid hand contact with the PCB top and bottom.
Finger-grip fasteners Plug-ins must be withdrawn and inserted using their
finger-grip fasteners/pulls. Never withdraw or insert using
attached cables, as damage to the plug-in connector and
its PCB attachment can occur. If not complied with, the
Aviat Networks warranty may be voided.
Hot-swappable Plug-ins are hot-swappable.
• Removal of an in-service payload plug-in will interrupt its
traffic.
• Removal of the NCC will affect all traffic - unless
protected by an NPC.
• Removal / replacement of the FAN does not affect traffic.
Engaging backplane
connector
When installing a plug-in, ensure its backplane connector
is correctly engaged before applying sufficient pressure to
bring the plug-in panel flush with the front panel.
Revision time lag When swapping or installing plug-ins, up to 60 seconds can
be required for the INU/INUe to show its revised status via
the front panel LEDs, or via Portal.
EMC integrity Plug-ins and blanking panels are held in place by captive
finger-screws. Ensure the finger-screws are fastened as
failure to do so may compromise EMC integrity and fan
cooling.
RACs
Connecting and
disconnecting the RFU
cable at the RAC
Never disconnect or reconnect an RFU cable to a RAC
without first turning the power off to the INU or
withdrawing the RAC from the backplane.
Note: The RFU cable provides the power feed to the IRU 600.
Arcing during connection and disconnection at the RAC
on a live RAC can cause damage to connector contact
surfaces. Power spikes caused by live connection and
disconnection may also cause errors on other traffic
passing through the INU/INUe. The only exception to
live disconnection and connection should be for checks
of protected operation at link commissioning.
Removing RAC from a
powered INU
When removing a RAC from a powered INU, always the
disengage the RAC from the backplane before
disconnecting its RFU cable. Similarly before inserting an
RAC, always reconnect the RFU cable before engaging the
backplane.
