Hi all
An APG40 is an Input-output Sytem
it allows to comminicate to the CP, and remote site
using telnet for example
APG40 is seen as one system of two windows server (node A, node B)
When one system is Active, the other one is passive
The Operating System, is embedded in a card (The System Board)
on the system board you have two connection in order to communicate to the CP (IPN Connection) you have as well mousse and keyboard connection.
The other connection that allows to communicate with the external (Ethernet Public port,Maintenance Port)are on the Peripheral board.
All data are collected and sent to the data disks (embedded in PSU/HDD Board).
Only the active node can access to the data disk and we have two data disks boards:
one in node A, and one in node B, that are mirrored thanks to the RAID-1
We have as well an alarm board, on which we can connect an alarm display
