C.5 Replacing the OSN Module Only (RMA)
This procedure describes how to replace the OSN module for maintenance purposes
(RMA). This procedure is intended for replacing an OSN module of the same type i.e. this
is not an upgrade procedure.
To RMA the OSN module:
1. Shutdown the SBA server (see Section 11.19.2 on page 139).
2. Remove the OSN module from Slot #2:
a. Gently and slowly pull the OSN module's handle until you hear the first click
sound; the handle is now partially pulled out and the module undergoes a
shutdown sequence indicated by the slow-flashing Hot Swap Blue LED on
the module.
b. When the LED stops flashing and is constantly lit, indicating that the
shutdown sequence is complete, disconnect any cables that may be connected to
the module.
c. Grip and gently pull the module's handle to slide the module out of the slot.
3. Perform the required maintenance actions.
4. Reinsert the OSN module into Slot #2 (see figure below):
a. Hold the new OSN module in the correct orientation, as shown in the figure
below, and gently insert the module into the slot, sliding it along the slot's guide
rails until it makes contact with the card-edge connector located on the
backplane.

b. Push the module's handle until it clicks firmly into the slot; the operating system
on the OSN server starts up.
