Chapter 2 Hardware Setup
There are some points that should be paid attention to when setting up
D210P/DE210P.
2.1 Span type setup
Each DIP switch controls a span configuration for E1 or T1 mode. Setting
DIP1 to ON means SPAN1 will work at E1mode.Setting DIP1 to OFF
means SPAN1 will be T1.
2.2 CardID switch setup
If want to install more than one card of D210P/DE210P 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 forth.
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
D210P/DE210P on your machine.
