This KB article addresses when only one node will not power-on in an ECS Gen1 or Gen2 system.
One node will not power on in an ECS Gen1 or Gen2 system.
Bad blade server or bad chassis.
For ECS Gen1 and Gen2 systems, there are redundant Power Supply Units (PSUs) which supply power to a chassis and up to 4 blade servers in the chassis.
Based on this, if 1 node out of 4 will not power on, the issue can’t be the PSUs because the other nodes in the same chassis are powered on.
The issue has to be the blade server or the chassis itself.
Using an example where node 4 will not power on, one can swap the blade server from the node 3 position to the node 4 position and vice versa.
If the issue stays with the slot where node 4 resides, the issue is the chassis. If the issue follows the blade server, then the blade server is at issue.
Note: This sort of troubleshooting can only be done at install time before the OS and ECS software is loaded on the system.
