juniSystemModuleTable
1.3.6.1.4.1.4874.2.2.2.1.3.4
A table of system module and sub-module information. In this table, a
module refers to a physical module (board) or a sub-module.
A physical board may contain a single module or multiple sub-modules.
For example, an ERX line card is a single module and appears as single
entry in this table. An I/O adapter is a module that doesn't provide
any operaitonal state information and it also appears as a single entry
in this table. A second generation E-series SRP/SFS hardware module
contains two sub-modules, each with its own operational state
information: a System Resource Processor (SRP) sub-module and a Switch
Fabric Slice (SFS) sub-module, which appear as two separate entries in
this table, one for each sub-module.
