Configuration recommendations
Standard SCM configurations come without SFP or XFP transceivers installed. To protect the internal
components of the SCM, transceivers or filler plugs must be installed in all empty sockets:
The Base Ethernet configuration supports up to four SFP transceivers and one XFP transceiver, with
filler plugs installed in unused sockets.
The Fabric Ethernet configuration supports up to four XFP transceivers, with filler plugs installed in
unused sockets.
For a list of tested and qualified transceivers and filler plugs, see the Support section of the RadiSys
Web site at

.
Transceiver installation
SFP and XFP transceivers can be installed on the SCM
at any time, but RadiSys recommends performing the
installation before the SCM is installed in the shelf.
The illustration shows the correct orientation for
inserting an SFP transceiver. The SFP you use may vary
in appearance depending on manufacturer, but should
follow the same insertion guidelines. Use these same
guidelines when inserting XFP transceivers as well.
1. Follow ESD precautions and make sure you are
adequately grounded.
2. Remove the transceivers and the SCM from their
antistatic bags.
3. On the SCM’s faceplate, remove the filler plugs
from the sockets in which you are installing the
SFP or the XFP transceivers. For sockets not being
used, keep the filler plugs in place to protect the
internal components of the board.
4. Make sure the transceiver’s bale (the latch on the
cable side of the transceiver) is in the closed
position. This ensures that the transceiver will snap
into position when inserted into the socket.
5. How you insert the transceiver into the socket depends on the SCM’s orientation:
If the SCM is oriented vertically, insert the transceiver so the connector side is on the left.
If the SCM is oriented horizontally, insert the transceiver so the connector side is down.
6. Once inserted into the socket, carefully slide the transceiver until its connector is fully seated and
snaps into position.
7. Repeat the above steps for each transceiver being installed.
8. For transceivers with cable plugs installed on their cable side, keep the plugs in place until you are
ready to plug cables into the transceivers. The cable plugs protect the internal components of the
transceivers.
