6.6.1. The Boot Priority Parameter
Normally, when an "On" or "Reboot" command is invoked, the RPC will switch on its
circuits 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 circuits
are switched On, by assigning a priority number to each circuit, rather than by requiring
the user to make certain that devices are always connected to the RPC in a set order.
Likewise, when new devices are added to your equipment rack, the Boot Priority
Parameter eliminates the need to disconnect all existing devices and then rearrange the
circuits connected to the RPC (and re-define circuit parameters) to ensure that they are
switched on in the desired order.

6.6.1.1. Example 1: Change Circuit A3 to Priority 1
In the Example shown in Figure 6.1, we start out with all Circuits set to their default Boot
Priorities, with Circuit A1 first, Circuit A2 second and so forth.
Next, the Boot Priority for Circuit A3 is changed to Priority 1. This means that Circuit A3
will now be switched On first after a reboot, and that Circuit A1 will now be switched On
second, Circuit A2 will be third, etc..
Note that when the Boot Priority for Circuit A3 is set to 1, the Boot Priorities for all circuits
that were previously Booted before circuit A1 are now lowered by a factor of one.
