Before Power 10, only one IP address was requested on power servers ASMI to manage it.

Now you have first the eBMC, but before starting a power 10, also add a VMI IP address.

default login/password for eBMC: admin / admin 

If you use DHCP on the HMC, the eBMC of Power 10 'll appear into HMC interface. Do not start the Power, first you have to set a password, it's both HMC access and admin password for the eBMC.

Before power on the server choose action, and VMI configuration (IP address), if IP is static, then configure one, else change to DHCP.

Select the same eBMC network interface the HMC is cabled to.
Note that the adapters may list eth1 first, however eth0 is typically used for the first HMC. If 2 HMC are used, both have to be setup

If this step is missed, when server is started, you 'll have a connection lost on the HMC !

Now you're able to power on.

You can either see the power progress on

• the HMC
• on eBMC web interface connecting as admin, you have host console
• using ssh admin@<eBMC> -p 2200

The VMI interfaces share the physical connection of the eBMC ports but have their own IP (DHCP or static)
