What is the default power-on sequence when line cards with Junos Trio chipsets are in the same chassis with other types of line cards?

Question

If the set chassis network-services attribute is not configured, the following is the line card power-up rule:

If the first PIC concentrator powered up is a DPC, then only DPCs within the box are allowed to power up.
If the first PIC concentrator powered up is an MPC, then only MPCs are allowed to power up.

As of Junos OS Release 10.2 and later, the power-up rule has been changed to the following:

If the set chassis network-services attribute is configured as ip at start time, any MX Series device-supported boards (such as DPC, FPC, and MPC) will boot.
If the set chassis network-services attribute is configured as ethernet at start time, any MX Series device-supported boards (such as DPC, FPC, and MPC) will boot.
If the set chassis network-services attribute is configured as enhanced-ip at start time, only MPCs and MS-DPCs are powered on in the chassis. Non-service DPCs do not work with enhanced network services mode options.
If the set chassis network-services attribute is configured as enhanced-ethernet at start time, only MPCs and MS-DPCs are powered on in the chassis.
