Description
The CPU Module contains the single board computer, the I/0 distribution board, and the internal modem. There are four positions in this module. The top slot is designated as the first slot because the VME bus expands from the top down. Due to special routing of signals in the backplane and VME terminator board the first slot is the last logical slot. The first slot in the CPU Module has a partial Pl only VME bus. The Pl only interface to the VME bus is used by the I/0 distribution board for communication to the system.
I/0 Distribution Board The I/ 0 distribution board contains all the input and output connections from the single board computer. It is a single wide VME form factor board. The I/0 distribution board has four primary functions: 0 System power control These circuits, powered by the base system power supply, turn the modules’ power supplies on and off. The circuits are connected to the key lock switch located on the front of the CPU Module. 0 Power monitor This circuit detects when any module power supply is out of regulation. 0 Modem and cooling reset S900RF/D4 When the keylock switch is turned to the reset position, the internal modem and the cooling failure power shutdown circuitry is reset.
1. Temperature monitor Each module’s temperature is monitored for two thresholds. At the first threshold, a cooling failure warning is issued, and a cooling failure LED is lit. At the second threshold, DC power is removed from the module.
2.Ethernet twisted pair output This circuit converts the Ethernet AUI output from the CPU board to a 10 Base T twisted pair output.
3.I/0 The front panel of the I/0 Distribution board provides: one SCSI-2 port (cable daisy-chained to SCSI modules) one RJ45 port labeled CONTROL (cable daisy-chained to SCSI modules) four serial ports one RJ45 twisted pair Ethernet port labeled 10 BASE T one DB15 AUI port modem present LED。
System Power Control
The I/0 distribution board provides circuits that enable and disable, (turn on and off), the power supplies in all system modules. The circuitry that does this is powered by the base system power supply. It is this circuitry that is connected to the keylock switch on the front of the CPU Module.
Power Monitor Function
A circuit on the I/0 distribution board detects when any module’s power supply 5 V output is substantially out of regulation. When the out of regulation condition persists, and for 200 millisecond minimum after, the I/0 distribution board drives VME system reset.
Keylock Switch Reset
Function 2-2 The I/0 distribution board resets the modem and the cooling failure power shut down circuitry when the switch is in the reset position. A system reset is not generated by this switch.
