Figure 1-7
Cisco CRS 8-Slot Line Card Chassis Slot Numbers—Rear (MSC) Side
The rear (MSC) side of the chassis has the following card slots:
•
Eight MSC slots (left to right: 7, 6, 5, 4...3, 2, 1, 0)
•
Four half-height switch fabric card slots (SM0, SM1, SM2, and SM3)
The MSC slot numbers are reversed from the PLIM slot numbers on the other side of the chassis.
Because an MSC mates with its associated PLIM through the midplane, MSC slot 0 is on the far right
side of the chassis looking at it from the rear (MSC) side.
PLIM slot 0 is on the far left side of the chassis, looking at if from the front (PLIM) side. MSC slot 0
and PLIM slot 0 mate with each other through the midplane, and so do all other MSC and PLIM slots (0
through 7).
