Line Card LEDs
Line card LEDs are described in the documentation specific to each line card. Refer to the installation
documentation that came with the card for to understand LED appearance and meaning.
Installing Switch Fabric Modules (SFMs)
A minimum of eight SFMs are required in order for the E1200 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.
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.
Install SFMs from the right-most slot (9) to the left-most slot (0).
NOTE: If you are not operating your E1200 system with redundancy, your SFM package will include blank
panels. Blanks are slot covers that have no board components or connector pins.
Flash In Use Green: flash memory card is in the process of a read or write process. Do not remove the
flash card when the In Use LED is lit.
Unlit: not in use
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
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.
