Inventory Mismatch:
The alarm will become active when a module is removed from, or moved to a different slot in the
chassis or inserted into a vacant slot. The alarm will also become active if the module is not
responding on the control bus. If the card is returned to the system in the same slot the alarm will clear
automatically within 1 minute. Pressing āResetā on this web page will record the current
inventory and reset the alarm. Note, an SOE entry is made if an inventory mismatch alarm
occurs.
Note, that modules are not shown removed unless they have been removed for approximately 4
minutes. If an inventory mismatch has occurred since the last reset it will be logged and will show on
a drop down screen on the web page. For example, removing and then inserting an input/relay output
card that was in slot 8 will show as the following:
Input/relay Output (24) card removed from slot 8 on Sat May 15 22:28:24 2004
Input/relay Output (24) card added to slot 8 on Sat May 15 22:36:33 2004
Control Bus Errors (CBE):
Activated when unexpected messages are detected on the control bus. This alarm will stay active until
manually cleared by pressing āReset.ā
SOE Trigger Major/Minor Alarm:
SOE triggers can be programmed to activate a major or minor alarm, these alarms become active based
on SOE events (See 7.3.3) Note that if the SOE triggers are reprogrammed while still in an alarm state
they will continue to be in an alarm state until the reset button is activated.
Bit Error Rate Alarm Threshold:
Each of the TPS Modules, except the Ethernet TPS Module will generate an alarm if the BER (Bit
Error Rate) exceeds the preset threshold. The alarm thresholds are shown on the following page.
Table 7-7. Bit Error Rate Threshold Settings
Slot #:
Indicates the physical slot the module is inserted into in the GARD 8000 chassis.
Location:
Indicates if the module is in the front or rear or the chassis.
In a 3 rack unit chassis the module location is also identified as occupying the left or right half of the
module on modules that have multiple function capabilities like the communications interface base or
the discrete I/O base.
In a 6 rack unit chassis the module location is also identified as occupying the top or bottom half of the
module on modules that have multiple function capabilities like the communications interface base or
the discrete I/O base.
