This article provides the layout and hardware specifications for Datto's SIRIS 6-(2 through 8) devices.
Environment 
- Datto S6-2
- Datto S6-3
- Datto S6-4
- Datto S6-6
- Datto S6-8
Description 
Devices in this range of sizes may use one of two types of Dell chassis, the Precision 3930 XL or PowerEdge R250XE. The features will be the same between the devices and the specifications of each are provided below. For information about determining the device model from the command line, refer to Updating SIRIS and ALTO firmware.
NOTE Once the device is plugged in, it will perform a function test. As a part of this test, you will hear the fans power on briefly and you may see some lights flicker on the device as well. This is normal behavior but is NOT an indication that the device has been powered on. In order for the device to properly power on, you will need to press the power button.
