.
In a 4 PSU configuration, mixing of 900W PSUs and 1400W PSUs is allowed. The
following rules apply when mixing PSUs.
A mixture of 900W and 1400W PSUs must be installed in group A and group B.
Example:
Bay 1 (
group A
) = 900W
Bay 2 (
group B
) = 1400W
Bay 3 (
group A
) = 1400W
Bay 4 (
group B
) = 900W
Power Supply Input Feed Wiring for Redundancy
The IMM2 Code for the x3850 X6 server requires power supplies in bays 1 and 3 to
be wired to feed 1, and power supplies in bays 2 and 4 to be wired to feed 2.
This is due to how the power supplies are internally connected and how the IMM2
determines if the system is redundant based on the
power policy selected. If the
power supplies are not correctly connected, the selected IMM2 power policy may not
function as intended. Power policies are discussed in the next section.
The following rules apply when connecting the server to input feeds for redundancy.
PSUs in group A and PSUs in group B must be balanced in both quantity and
power output (A=B). If the groups are not balanced, the system will not boot.
As an example, mixed wattages must be balanced:
Feed 1 (
group A
) = 900W and 1400W PSUs
Feed 2 (
group B
) = 900W and 1400W PSUs
Input power feeds for both group A and group B must be different for
redundancy. Example of a 2 PSU installation.
PSU 1 (
group A
) = Feed 1
PSU 2 (
group B
) = Feed 2
Input power feeds for both group A and group B must be different for
redundancy. Example of a 4 PSU installation.
PSU 1 (
group A
) = Feed 1
PSU 2 (
group B
) = Feed 2
PSU 3 (
group A
) = Feed 1
PSU 4 (
group B
) = Feed 2
The following illustrations depict how a x3850 X6 server should be wired for
redundancy in a 2 PSU configuration, a 4 PSU configuration, and a mixed wattage
configuration.
