8: System Control
A brick is identified by its rack, type, and slot (001c07). The structure of the brick location
is as follows:
rrrbss.p
where:
rrr
is the rack number.
b
is the brick type.
ss
is the slot location of the brick.
p
is the partition of the brick (not present if the system is not partitioned).
R-bricks are not associated with a partition.
In the example shown above, 001c07 is a Cx-brick in rack 001 and slot position 07.
Targeting Commands
If a command is not understood by the L2 controller, it is passed to the L1 controllers. The
destination determines which L1 controllers receive the command. A destination,
specified by the following, is a range of racks and slots:
rack
<rack list>
slot
<slot list>
The <rack list> specifies a list of racks. This can be a list delimited by commas, such that
2,4,7 specifies racks 2, 4, and 7. You can use a dash to specify a range of racks, such that
2-4 specifies racks 2, 3, and 4. Both nomenclatures can be combined, such that 2-4,7
specifies racks 2, 3, 4, and 7.
You can specify the
<slot list>
using the same nomenclature. The slot number is the
lowest unit number that the brick occupies. This number is located on the rack rail
slightly above where the bottom of the brick sits. For example, in Figure 8-17, the slot
number of the brick is 11.
