54 Installing RPMs, Line Cards, and SFMs
Installing Switch Fabric Modules (SFMs)
A minimum of eight SFMs are required in order for the E1200i system to operate properly. Slot 9 allows
for a redundant SFM, allowing up to ten SFMs in the E1200i system.
SFMs carry user traffic between line cards or between RPMs and a line card. SFMs plug directly into the
backplane, which provides high-speed access to the line cards. The switch fabric receives user data packets
and redirects them to the appropriate destinations according to the routing information.
Install SFMs from the right-most slot (9) to the left-most slot (0).
Primary Green: primary
Unlit: secondary (or standby)
Status This is a bi-color LED.
Green: operational
Amber: fault detected
Flashing green: booting
Unlit: in secondary mode or power is off
Caution: If you are not operating your system with a redundant (tenth) SFM, you must install an SFM blank to
avoid overheating and ensure EMI containment.
Step Task
1. Remove an SFM from the anti-static packaging.
2. Align the SFM with the guide and gently slide it into the slot until you feel the connectors engage with
the chassis backplane.
Note: Hold the SFM by the edges. Avoid touching the printed circuit board and connector pins. Extend
the top and bottom card levers before you insert the card into the slot.
3. Rotate the lever to seat the backplane connectors and card in place.
4. Secure each SFM in place by tightening the captive screw.
5. Continue the process for the remaining SFMs.
6. Align any blank panels with the guides and gently slide toward the backplane. Secure each blank panel
by tightening the single captive screw.
Note: If you are not operating your E1200i system with redundancy, your SFM package will include blank
panels. Blanks are slot covers that have no board components or connector pins.
