Priority Details
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.
Plug-ins must be withdrawn and inserted using their finger-grip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 Alcatel-Lucent warranty may be voided.
Plug-ins are hot-swappable. Removal of an in-service plug-in will
interrupt its traffic. Removal of the NCC will affect all traffic (unless
protected by an NPC).
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.
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 9500 MXC CT.
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.
Never disconnect or reconnect an ODU cable to a RAC without first
turning the power off to the INU or withdrawing the RAC from the
backplane.
Note: The ODU cable provides the power feed to the ODU. 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.
