1.2 Subrack Classification and Numbering Rules
Subrack Numbering Rules
Each subrack has a unique number.
The subracks in a cabinet are numbered in ascending order from bottom to top. The basic
subrack is the first subrack from the bottom and is numbered 0.
If there are multiple cabinets, the subracks are numbered in ascending order based on the
cabinet numbers.
Figure 1-1 illustrates how subracks are numbered.
Figure 1-1 Subrack numbering rules
Figure 1-1 uses a cabinet configured with more than two subracks as an example. Number subracks
based to the subrack numbering rule depending on the actual situation.
Subrack Slot Numbering Rules
The slots in an subrack are numbered from 1 in ascending order from bottom to top and then
from left to right.
Figure 1-2 illustrates how the slots are numbered in an F8002 subrack.

The MXUs implement subrack management and data exchange in the subrack.
The MXUs work in active/standby mode. Only the active MXU executes management
tasks. The MXUs also manage the two fan trays through the RS485 bus and the two
PEMs through the Inter-integrated circuit (I2C) bus.
The service data and signaling data from a service board is forwarded in eFabric
channels to the MXUs through the backplane. The MXUs then forward the data to
another service board.
The management data from a service board is forwarded in Base channels to the MXUs
through the backplane. The MXUs then forward the data to another service board.
The power distribution box (PDB) in the subrack provides two DC power supplies to the
subrack.
