Chapter 2 Hardware Setup
There are some points that should be paid attention to when setting up
D230P/DE230P.
2.1 Span type setup
Each DIP switch controls one span configuration for E1 or T1.Setting
DIP1 to ON means SPAN1 will be E1.Setting DIP1 to OFF means
SPAN1 will be T1.
2.2 CardID switch setup
If want to install more than one card of D430P/DE430P in a PC, you
should take care of the card ID switch. There are two pieces of rules you
must obey:
The first card must be set to 0, which is a card that will be initialized
(i.e. installing driver) firstly when the system boot up. And the second
should be set to 1, and so on.
At most cases, Linux will initialize PCI devices according to their slot
order. The slot nearest to the CPU will be initialized firstly and the far
end slot will be initialized at last. That is to say, the card which is
nearest to the CPU ID should be set to 0 if there is more than one
D430P/DE430P on your machine.
