PR-MAINT (Maintenance Processor
[TN2404/TN790 RISC Systems])
The TN2404/TN790 Processor circuit pack is comprised of the RISC Processor
(PROCR), the Maintenance Processor (PR-MAINT), and the Memory (PR-MEM).
PR-MAINT is responsible for monitoring the sanity of the RISC Processor.
PR-MAINT contains the hardware required for controlling the environmental
conditions. The Maintenance/Tape Processor provides the serial interfaces for the
administration terminal and DCE port. The Maintenance Processor also provides
the communications interface to INADS for alarm reporting and remote
maintenance capability. INADS connectivity is through the internal or external
modem. The external modem is connected to the DCE port. When the external
modem is the administered modem option the internal modem is disabled.
The TN2404/TN790 has a higher speed 9600 baud internal modem or can
support an external modem connected to the DCE port.
