LTC 8901 Series CPU Selection Switch
The Switch Control input to the LTC 8901 Series can be over ridden using the front panel
switch. This switch allows manual selection of either the primary or backup CPU. This switch
should be left in the AUTO position to enable the automatic switchover functions. The AUTO
LED on the front panel illuminates to indicate proper switch position. If the LTC 8943/95
System Controller PC is not connected, the CPU cannot operate in a redundant mode even if
its front panel switch is set to AUTO. However, the system will continue to operate in a
nonredundant mode because the communication signals to the matrix bays continues to be
supplied from the primary CPU.
If the CPU bay front panel switch is used to manually select a CPU, the appropriate LAN port
enabling must still occur. The System Controller performs this action, even if the front panel
switch is used to manually override automatic CPU selection. If the System Controller is
connected and the System Supervisor software is running, the System Controller will
automatically enable and disable the appropriate ports (when the System Supervisor software
is running, the Controller Activity LED on the front of the LTC 8901 Series CPU bay will be
blinking).
If a manual selection is made when the System Controller is not connected or the System
Supervisor software is not running, the installer must manually ensure that the selected
CPU LAN connection is plugged into an active port, and that the nonselected CPU LAN
connection is either plugged into a disabled port or unplugged.
