Two versions of A
X
M hardware will be available. One uses the K2LCN
(or K4LCN) board as the LCN node processor and the other uses the
HMPU/ LLCN/QMEM combination of boards as the LCN node
processor.
The diagrams on the following two pages show the major hardware
components that make up the A
X
M hardware. Pay particular attention to
the following:
• Names and acronyms of the components
• Interconnection between components
• External connections to:
– LocalControlNetwork(LCN)
– Plant Information Network (PIN)
– “Console terminal” (when required for initial configuration or
troubleshooting). A console terminal is a simple keyboard and
display device that has no processing capability. Several device
types can be used to satisfy this requirement. They are addressed
later in this manual.
– Modem for Technical Assistance Center (TAC) access (if
required for complex problem isolation activities).
– DAT drive (optional) to support hard disk backup, restore, and
software update activities. It is also used for recovery activities in
the event of some hard disk drive failures.
– CD-ROM (optional) provides access to the HP-UX online
software documentation.
