To calculate the power consumption of a chassis add the power of the spines, leafs, and management modules.
Power Consumption of Chassis Parts
Part | Maximum (W) |
Quantum HDR Leaf with passive cables | 582 |
Quantum HDR Leaf with 40 optical cables | 819 |
Spine | 309 |
Management module | 217 |
The table above assumes the QSFP cable power consumption specified in the table below. (Please note that QSFP module power is related to the module itself and is not referenced to AC plane.)
QSFP Cable Power Consumption
QSFP Cable Type | Typical (W) | Maximum (W) |
Optical | 4.9 | 5.9 |
To calculate the total power consumption of the switch system in a certain configuration, fill out the table below in the following manner:
In the Power column fill in the desired typical or maximum values.
In the Quantity column, fill in the desired configuration. (Please note that the number of fans is not configurable and is always 1.)
Get the total power per each FRU by multiplying values in adjusted columns in the same row.
Get the total switch system power consumption system power by multiplying and summing up all the values.

The weight of a customized chassis can be calculated by adding the the following weights:
Spines
Leafs
Leaf blanks
Management modules
Management blanks
Chassis weight already includes 9 pre-installed PS units.
Rail kit, cable supporters, and cable management kits' weight is not included.

There are three thermal threshold definitions for the switch which impact the overall switch system operation state: Warning, Critical and Emergency.
Warning – 105ºC
On managed systems only: When the switch crosses the 100ºC threshold, a Warning Threshold message will be issued by the MLNX-OS® management SW, indicating to system administration that the switch has crossed the Warning threshold.WarningNote that this temperature threshold does not require nor lead to any action by hardware (such as switch shutdown).
Critical – 120ºC
When the switch crosses this temperature, the firmware will automatically shut down the device.Emergency – 130ºC
In case the firmware fails to shut down the switch upon crossing the Critical threshold, the switch will auto-shutdown upon crossing the Emergency (130ºC) threshold.
EMI testing on a fully populated chassis has been performed with the chassis installed in a closed two-door rack with a floor plate using the chassis installation kit supplied by Mellanox Technologies.
