DIP Switches on the TN18EFI Board
The OptiX OSN 8800 universal platform subrack supports the master/slave subrack
management mode. When this mode is used, the ID of each subrack must be set by using two
DIP switches on the EFI board.
DIP switches within the board (type A): Figure 4-30 shows the position of the DIP switches
on the EFI board.

The TN18EFI board has a set of eight DIP switches. ID1-ID4 correspond to bits 1-4 of
SW2, and ID5-ID8 corresponding to bits 1-4 of SW1. Among these ID values, only
ID1-ID5 are valid. ID6-ID8 are reserved. The bits from high to low are ID5-ID1. Each
DIP switch can be used to set a binary digit, 0 or 1. When the DIP switch is toggled to
ON , the value of the corresponding bit is set to 0.

A maximum of 32 states can be set. The value is 00000 by default. "0" indicates the
master subrack. The other values indicate slave subracks. As shown in
Figure 4-30 , the
value represented by the ID5-ID1 is 00001, which is 1 in decimal system. That is, the
subrack ID is 1.
