Basic Configuration
5.7.1. The Boot Priority Parameter
Normally, when an "On" or "Reboot" command is invoked, the MPC will switch on its
plugs in their default, numeric order. Although in many cases, the default, numeric order
will work fine, there are other cases where an individual device (such as a router) must
be switched on first, in order to support a second device that will be switched on later.
The Boot Priority Parameter simplifies the process of setting the order in which plugs
are switched On, by assigning a priority number to each plug, rather than by requiring
the user to make certain that devices are always connected to the MPC in a set order.
Likewise, when new devices are added to your equipment rack, the Boot Priority
Parameter eliminates the need to unplug all existing devices and then rearrange the
plugs connected to the MPC (and re-define plug parameters) to ensure that they are
switched on in the desired order.
Notes:
• No two plugs can be assigned the same Boot Priority number.
• When a higher Boot Priority is assigned to any given plug, all subsequent
plugs will have their boot priorities lowered by a factor of 1.
• The Boot Priority is also displayed on the Plug Status Screen.
5.7.1.1. Example 1: Change Plug A3 to Priority 1
In the Example shown in Figure 5.11, we start out with all Plugs set to their default Boot
Priorities, with Plug A1 first, Plug A2 second and so forth.
Next, the Boot Priority for Plug A3 is changed to Priority 1. This means that Plug A3
will now be switched On first after a reboot, and that Plug A1 will now be switched On
second, Plug A2 will be third, etc..
Note that when the Boot Priority for Plug A3 is set to 1, the Boot Priorities for all plugs
that were previously Booted before plug A1 are now lowered by a factor of one
