Ensure that rack power meets the following requirements.
Verify that each device in the rack has a connection to each PDU.
VMware recommends that you cable each server to the nearest power port so that the cable length can be kept to a minimum. Length of power cables should be as follows.
From the Physical Server: (9) .5m (3) 1m
From the Top-of-Rack Switch: 1.5m
From the Inter-rack Switch: .5m
It is common for power cables within a rack to be longer than required. However, if excess cabling is not managed properly, it may create electromagnetic interference. Avoid bundling of excess cables as this may lead to the cables being damaged due to bending.
The power connector from the PDU must match the power connector in the Site Readiness Assessment.
Power cables must be seated properly from each device to the PDU.
The cables connect the primary PDUs to the other components must be blue and the cables from the secondary PDUs must be red.
Power cables should not be in an area where there is a risk of touching sharp edges, excessive heat, or subject to pinching between sliding rails.
