Installing Switch Fabric Modules (SFMs)
Two SFMs are required for the E300 system to operate optimally. The system operates at non-line rate if 
only one SFM is installed and operational.

1 Route cables, to the right, across the cable bracket. 
2 Thread cables horizontally through the wire-tie loops.
