S400 units that were shipped prior to June 1 2015, may on rare occasion experience one or more fans disengaging during transit.
This will be evident when the unit is first removed from the box and/or when the unit is powered up for the first time.

Affected Systems:
SG-S400
CAS-S400
MAA-S400

2. After logging in to the appliance, append the url to include /support. For example, https://<ipaddress>/support
3. Click on the link to Download Syslog.
4. Extract the syslog.tar file and navigate to var\log\syslog.

To correct this issue, any fan(s) that have disengaged during transit need to be re-seated into the fan tray.
After re-seating the fan(s), the unit will function normally.

Modifications to S400 box packaging have been made to provide additional support and stop fan(s) from disengaging during transit.
This increased packaging provides added support and stops any fan(s) from disengaging during transit.
To re-seat the fan(s):

1. Unlock and open the middle top cover.
2. Re-seat the fan(s) by aligning the fan with the motherboard fan connector, so that the fan slots easily into place.
3. If the unit is powered up when the fan(s) is re-seated a green LED will be displayed.
