Powering Up the System

Before Powering Up

The system's built-in Automatic Slot Configuration automatically sets up station and line cards when you
initially power up the system. On power up, the system scans the cards from left to right and sets up the sta-
tion and line numbering as follows:
Extension numbers will begin with 300 in the first slot and increment from left to right.
❥
Line numbers will begin with 101 (starting from the first installed COIU or T1/E1/PRI Card) and will
❥
also increment from left to right.
For example, in a 16x32, the numbering will be:
❥
1st 16ESIU Card = Extensions 300-315.
2nd 16ESIU Card = Extensions 316-331.
16COIU Card = Lines 101-116.
In addition, the system will also automatically set up a station or line card when you plug it in hot.
