Configuring Master/Slave Subracks
Changing the ID of a subrack leads to service interruption.
CAUTION
DIP switches on the TN18EFI board (for the Universal Platform Subrack)
When it is the first time that the EFI board is installed in an universal platform subrack or when the changed
subrack ID is the same as the previous subrack ID, the subrack_ID LED on the SCC and EFI boards will display
the newly specified subrack ID.
If the newly specified subrack ID differs from the previous subrack ID, the subrack_ID LED on the SCC and EFI
boards will alternately display the previous subrack ID and the EE value. When this occurs, determine whether
the newly specified subrack ID is correct. If it is correct, power-cycle all the PIU boards inside the subrack to
make it take effect. If it is incorrect, configure the DIP switches again to recover the previous subrack ID.
CAUTION
Type 1: five DIP switches on the board panel
•The TN18EFI board has a set of five DIP switches whose IDs are ID1-ID5 from the lower bit to the higher
bit. Each DIP switch can be used to set a binary digit, 0 or 1. When the DIP switch is toggled to “0”, the
value of the corresponding bit is set to 0.
•"00000" indicates the master subrack. The other values indicate slave subracks.
DIP switches must be toggled to the topmost
or the bottommost. Otherwise, the subrack ID
cannot be intuitively identified.

If the DIP switch is blocked by a network cable, properly
move the network cable so that the DIP switch can be
configured. After the DIP switch configuration is completed,
move the network cable to its original position.
