Installing RPMs, Line Cards, and SFM3s | 49
CAUTION: If you are not operating your system with a redundant (tenth) SFM3, you must install an SFM3
blank to avoid overheating and ensure EMI containment.
NOTE: If you are not operating your E1200 system with redundancy, your SFM3 package will include blank
panels. Blanks are slot covers that have no board components or connector pins.

Line Card Cable Management Systems
Dell Force10 provides a variety of E1200 chassis cable management systems to manage your fiber optic
and auxiliary cables connecting to line cards. For details, see the Dell Force10 price list. For installation
instructions, see the instructions that come with the specific cable management system.
Step Task
1 Remove an SFM3 from the anti-static packaging.
2 Align the SFM3 with the guide and gently slide it into the slot until you feel the connectors engage with the
chassis backplane.
NOTE: Hold the SFM3 by the edges. Avoid touching the printed circuit board and connector pins. Extend the
ejector lever before you insert the SFM3 into the slot.
3 Rotate the lever to seat the backplane connectors and card in place.
4 Secure each SFM3 in place by tightening the captive screw.
5 Continue the process for the remaining SFM3s.
6 Align any blank panels with the guides and gently slide toward the backplane. Secure each blank panel by
tightening the single captive screw.
