1.3.2 CIU System Status

CIU System status in Web interface reflects the current status of the
CIU. This status is also indicated by the Ring of light.
CIU system status when normal will not have any sub-parameters
listed. However when in warning or fail state, the parameter will be
expanded with contributing sub parameters.

1.3.2.1 Parameters responsible for determining the CIU system status:

Points to note:
If one or more conditions indicate "Fail", the CIU system status is set

to "Fail".
Troubleshooting & Maintenance Guide
CIU 888
Description
Displays the date and time when the CIU 888 was
last powered up. When the CIU 888 is powered up,
and event record is created.
Displays the date and time when the CIU 888 was
last powered down. When the CIU 888 is powered
down, an event record is created.
Displays the reason for the last power down of the
CIU 888. Possible reasons are:

Power cycled (1)

Power cycled (2)

Power cycled (3)

Power cycled (4)

Power cycled (5)

Power cycled (6)

Internal FPGA failure

Overheated Core Processor

Restart by watchdog due to COMe issue

Restart by watchdog due to secondary controller
issue

User initiated shutdown

Unknown
Displays the status of the FPGA built into the
CIU 888.
The FPGA status is checked immediately after
startup of the CIU 888 and every 10 seconds during
normal operation. If the FPGA status is 'TBD', an
event record will be created and the CIU 888 will
power down.
Displays the status of the BIOS built into the
CIU 888.
Displays the version of the secondary micro
controller.
If the LCD type is not supported, a fatal failure may
be initiated immediately.
