VRC Rear Panel
The rear panel of the VRC contains indicators, switches, and connectors for
maintenance, configuration, and connection to other system components. The power
switches for slots 5 and 6 are also located here, as well as the chassis ID wheel.
Drive Bays
These bays contain the slots for and physical location of the system hard drives when
VRC-mounted application processors are used. Generally one drive is present per
processor, but additional drives may be added if system performance requires them.
Application Processor
In VRC-mounted configurations, the application processor is a “stripped down”
version of a Solaris or Windows computer: it contains the CPU, memory, and printed
circuit boards needed for both standard OS functions as well as basic MPS1000
transaction processing. One application processor is present per VRC in slot 6, but if
the VRC is populated with multiple TMS’ (which may in turn contain more than one
phone line interface card) and large numbers of spans, system performance may be
degraded and require the addition of another processor.
In typical rack-mounted configurations, there is one application processor per VRC,
and they are mounted at the bottom of the cabinet. This application processor is
similar in makeup to a typical Solaris or Windows computer. In either form, an
additional application processor may be added where instances of dual redundancy is
desired.
