An FIC refers to a subcard on which every port works at a rate of lower than 1 Gbit/s. An HIC refers to a
subcard on which every port works at a rate of at least 1 Gbit/s.
If ten 10GE interfaces or less are used on an CX600-X2-M16, configuring them evenly on the left and right
sides of a frame is recommended.
For the CX600-X2-M16 that has the NPU-50\NPU50-E installed, 2-port 10GBase PICs cannot be installed
in both slot 5 and slot 12, and slots 1, 2, 3, 4, 13, 14, 15, and 16 support only PICs whose total bandwidth
is smaller than or equal to 2 Gbit/s; for the CX600-X2-M16 that has the NPU-120/NPU-120-E installed,
slots 1, 2, 15, and 16 support only PICs whose total bandwidth is smaller than or equal to 2 Gbit/s.
Master/slave
– In master/slave mode, the master NPU forwards services of all subcards, and the slave
NPU is a hot standby backup. The slave NPU takes over the services only when the
master NPU is unavailable, for example, when the master NPU fails or restarts. This
implementation prevents service interruptions when the master NPU is unavailable.
– In master/slave mode, each NPU manages all the sixteen subcards, PICs 1 to 16 in
Figure 3-5.
