Configure chassis power
To configure the chassis power settings:
1. Click Devices > Chassis > View Details > Settings > Power.
The Power configuration section is expanded.
2. Select Enable Power Cap to specify the maximum power consumption capacity for the chassis. The Power Cap limits the
power consumption of the chassis. When the power cap is reached, the sleds are throttled based on their power priority. You
can specify the capacity in Watts, BTU/h, or percentage. The Power Cap option is displayed only if the Enable Power Cap
check box is selected. The recommended power cap is 0-32767 Watts or 0-100 %. If you change the power cap in BTU/h,
the power cap in W also changes.
MX7000 chassis supports power sources of 110 Volts and 220 Volts.
3. In the Redundancy Configuration section, select the required redundancy policy.
Power redundancy policies facilitate management of power consumption and power failure tolerance in the chassis. The
available options are:
● No Redundancy—This policy distributes the enclosure power load across all PSUs. There are not any specific PSU
population requirements for No Redundancy. The intent of the No Redundancy policy is to have the highest possible
limit for power enablement of devices added to the enclosure. If there are single or multiple PSU failures, then the
enclosure limits the performance to operate within the power capabilities of the remaining PSUs.
● Grid Redundancy—This policy distributes the enclosure power load across all PSUs. The six PSUs are organized into
two groups: Grid A consists of PSUs 1, 2, 3, and Grid B consists of PSUs 4, 5, 6. It is recommended that the PSUs are
populated in the following order: 1, 4, 2, 5, 3, 6, where an equal number of PSUs on each grid is optimized for Grid
Redundancy. The grid with the largest PSU capacity determines the limit for power enablement of devices added to the
enclosure. If there is a grid or PSU failure, then the enclosure power is distributed among the remaining PSUs with the
intent that a single healthy grid continues to provide power to the system without degrading the performance.
● PSU Redundancy—This policy distributes the enclosure power load across all PSUs. There are no specific PSU
population requirements for redundant PSUs. PSU redundancy is optimized for a population of six PSUs, and the
enclosure limits the power enablement of devices to fit within five PSUs. If there is a single PSU failure, then the
enclosure power is distributed among the remaining PSUs without degrading the performance. If there are less than six
PSUs, then the enclosure limits the power enablement of devices to fit within all populated PSUs. If there is a single PSU
failure, then the enclosure limits the performance to operate within the power capabilities of the remaining PSUs.
4. In the Hot Spare Configuration section, select the Enable Hot Spare configure the Hot Spare primary grid.
The Hot Spare feature facilitates voltage regulation when power utilization by Power Supply Unit (PSUs) is low, considering
the total output capacity of the PSU. By default, the Hot Spare is enabled. When the Hot Spare is enabled, a redundant PSU
is put in sleep state when the power utilization is low. The Hot Spare is not enabled if the:
● PSU redundancy is inactive.
● Power budget of the system configuration exceeds the PSU output capacity.
● Grid Redundancy Policy is not selected.
The MX7000 PSUs support the Hot Spare feature with three PSU pairs. The feature enables a PSU pair to have one active
PSU and one PSU in sleep mode while the enclosure power consumption is low, and the three PSU pairs meet all the power
requirements for the enclosure. This enables efficient power utilization when the overall enclosure power requirement is low.
The partner PSU wakes the paired PSU from sleep mode by sending a WAKE signal when the enclosure power requirement
increases. The PSU pairs for MX7000 are PSUs: 1 & 4, 2 & 5, and 3 & 6.
5. From the Primary Grid option, select the PSU where you want to enable the Hot Spare, from the drop-down.
6. Click Apply to save the chassis power settings.
Configure chassis management network
You can configure the network settings for the management modules that are inserted into an MX7000 chassis.
● LAN/NIC interface
● IPv4
