Product Overview
Chassis slots
Chassis slots are coded and numbered to differentiate between management module slots, switch fabric module slots, and line card
slots. Management modules (MMs) must be installed only in slots M1 and M2. switch fabric modules (SFMs) must be installed only in
slots S1 through S6. There must be at least one switch fabric module installed in either slot S3 or slot S4. The line card slots, L1 through
L8, can be filled with any supported line cards. Unused slots must be filled with the correct filler panels to maintain adequate cooling.
