Assigning I/O Modules to the
Trusted
 System

To configure the SYSTEM.INI file, add I/O modules to the system layout of the
Trusted®
controller. At least one 8151 Communication Interface module must also be added. If additional slots are required for the system, add an expander chassis. When adding an expander chassis, a pair of 8311 Expander Interface modules must also be included in the controller chassis. All Expander Chassis must be connected to the Expander Interface modules.
When adding modules, the layout that displays in the
System Configuration Tool
 must match the layout of the physical
Trusted
 controller and expander chassis.
It is recommended to disable slots with no configured modules and that will never be used as companion slots or hot swaps. Disabling these slots removes them from the scanning process and reduces the processing times. Disabling a slot disables all communications for that slot; you can no longer hot swap a module or perform diagnostics on any module moved to the disabled slot. For this reason, do not disable any companion slots or smart slots and leave one slot active as a diagnostic slot.
Task
Procedure
Add a module to a slot
  1. From the
    System Configuration Tool
    , right-click an empty slot in the chassis.
    The
    Replace Item In Slot...
     dialog box display.
  2. In the
    Replace Item In Slot...
     dialog box, select the required module and then click
    OK
    .
    The module is added to the system layout and requires configuration.
Empty a slot
  1. From the
    System Configuration Tool
    , right-click the slot to empty in the
    System Layout
    .
    The
    Replace Item In Slot...
     dialog box displays.
  2. In the
    Replace Item In Slot...
     dialog box, select
    Empty Slot
     and then click
    OK
    .
Add and connect an expander chassis
  1. In the
    System Configuration Tool
    , right-click the empty space.
    The
    Insert New Chassis
     dialog box displays.
  2. In the
    Insert New Chassis
     dialog box, select the required
    Logical Chassis Number
     and then click
    OK
    .
    TIP: Add a maximum of 27 expander chassis. The number of added chassis must not exceed the maximum number defined in the parameters of the Processor.
    The expander chassis, including the two 8310 Expander Processor modules, display in the
    System Layout
    .
  3. To connect the Expander chassis and controller chassis, add a pair of 8311 Expander Interface modules to the controller chassis. It is recommended to use slot 1 and 2.
  4. Click the edge of the expanded chassis, then from the
    Chassis Connection
     dialog box, select a slot having an Expander Interface module, and then click
    OK
    . Selecting slot 0 disconnects the chassis.
    TIP: If no Expander Interface modules are added, an Expander Interface module is automatically created at the slot defined in the
    Chassis Connection
     dialog box.
Connect or disconnect an expander chassis
  1. In the
    System Configuration Tool
    , click the required 8311 Expander Interface module.
    The
    Expander Interface Parameters
     dialog box displays.
  2. To connect the chassis, from the
    Unconnected Chassis
    section, drag the unconnected chassis icon to a
    Not Connected
     channel in the
    Physical Connections
     section.
    The connected slot number displays beside the channel number.
  3. To disconnect the chassis, from the
    Physical Connections
     section, drag the connected chassis number to the
    Unconnected Chassis
     section.
Display the switch configuration for a connected expander chassis
  1. In the
    System Configuration Tool
    , click the edge of the expanded chassis.
    The
    Chassis Connection
     dialog box displays.
  2. From the
    Chassis Connection
     dialog box, click
    Switch Config...
    .
    The
    Switch Configuration
     window displays the positioning of the DIP switches located on the back of the Expander Chassis. If the switches are not correctly positioned, the expander communication link fails. Refer to the 8300
    Trusted
     TMR Expander Chassis for more information.
Disable an unused slot
  1. From the
    System Configuration Tool
    , click an empty slot in the chassis.
    The
    Empty Slot
     dialog box displays.
  2. In the
    Empty Slot
     dialog box, select the
    Disable scanning of this slot
     parameter, and then click
    OK
    .
