Slot arrangement
As a self-developed 2U device, each MSR 30-40 router provides four SIC slots and four MIM slots
respectively, delivering expansion of access and service capabilities. In addition, the SIC slide rail
between Slot 1 and Slot 2 can be removed so that two SIC slots can be extended to form a DSIC slot.
Similarly, Slot 3 and Slot 4 can be arranged to form another DSIC slot, and Slot 7 and Slot 8 can be
arranged to serve as a DMIM slot.
