Overheating
A sensor on the backplane will issue a warning at 45°C. Overheating is critical at
49°C. There are several possible responses if the system overheats.
If the server overheats:
1. Use the LEDs to determine the nature of the overheating condition.
2. Conrm that the chassis covers are installed properly.
3. Check the routing of the cables and make sure all fans are present and operating
normally.
4. Verify that the heatsinks are installed properly.
3-4 Drive Carrier LEDs
The chassis includes externally accessible SAS/SATA/NVMe drives. Each drive
carrier displays two LED indicators: an activity indicator and a status indicator. The
status indicator functions in RAID congurations. For non-RAID congurations, it
remains off. See the table below for details.
