Complete Shutdown Failure – If an operating system level failure has occurred, it is
possible that the processor will never be yielded for the shutdown to begin, even after
process priorities are equalized by the recovery function at the 80 second interval. After
two minutes, the S8300 will be reset by the hardware watchdog. The LED sequence is as
follows:
Removing the S8300 Media Server
The S8300 Media Server contains a Lithium/Manganese Dioxide battery.
CAUTION:
There is a risk of explosion if the battery is replaced by an incorrect type. Dispose of used
batteries according to the instructions.
NOTE:
The S8300 Media Server is inserted into the G350 Slot V1, whether it is the primary
server or a Local Survivable Processor (LSP). Although the S8300 can fit into any of the
slots on the G350, it only functions when inserted in Slot V1 on the left side of the G350.
The plate above the slot must be removed to provide clearance for the S8300.

Now allowed to proceed, processes begin to exit as the shutdown begins. As
processes exit, the TST LED flashes faster, and the YELLOW ACT LED remains
illuminated.
4
When shutdown has completed, the TST LED goes out, and the "OK to Remove"
LED comes on steady. At this point, it is safe to remove the S8300 module from
the G350.
1
After the shutdown button is pressed and held for at least two seconds, the "OK to
Remove" LED begins to flash at a constant rate. The TST LED flashes slowly at
first.
2
The TST LED remains flashing at a slow rate for 80 seconds, because shutdown
processing is being blocked by runaway processes. After 80 seconds, The
YELLOW ACT LED is illuminated, indicating that process priorities have been
equalized, and that diagnostic information has been saved for later analysis.
3
Despite the process re-prioritization, the shutdown is still blocked, and the TST
LED continues to flash at a slow rate. After two minutes, the hardware watchdog
resets the S8300. At this point, the RED ALM LED is illuminated and all others go
out. Although this begins restarting the S8300, it will be safe to remove the S8300
module from the G350 for approximately 15 seconds after the module resets.
