1 8665 Smart Router Overview
Currently, the control f unction ality can be run on ly o n the line units in slots 2 and 13, respectively
the leftmost and rightmost line units i n the network element. When both u nit s in slots 2 a nd 13 are
installed, the n etwork elem ent is fully redundant.
Note that the timing and alarm interfaces should be only used from slots 2 and 13.

8665 Smart Router Switch Unit (SU1)
8665 Smart R o uter switch unit SU1 is used for packet switching inside the network element. SU1 has
two separate switches. The main data plane switch, which has a capacity of 900 Gbps, a nd a separate
control plane switch with a c
apacity of 90 Gbps. Althoug h almost full data plane capacity can be
reached with one SU1, it is strongly recom m ended to use two SU1s in a redundant configuration, as
the traffic load will be shared between the two SU1 s to enhance throughput and laten cy

SU1 contains the followi
ng functional featu res:
• High speed data links w ith all line uni ts
• Local power supply
• CPU for local mana
gement
• Packet based Switch Fabric
• Node control packet switch
1.1.3 Cooling
8665 Smart R o uter has three hot swappable fan modules.

When there is only one SU1, packet header terminations and a dditions, packet s ize and other factors affect the throughput.
