McTi Board ID Switch Bank Settings
A bank of dip switches on each McTi board is used to identify the board on the SCSI
bus. If a McTi board is determined to be faulty and must be replaced, it is essential
for the new board to have the same address ID as the board that was removed. Use
the switch settings on the faulty board as a guide for setting the switches on the new
board. The sub-sections to follow describe switch banks by board type.

Dip Switch Settings for McTi-8E, McTi-8R, McTi-8L and McTi-24 Boards
Switch bank SW1 on each McTi-8E, McTi-8R, McTi-8L and McTi-24 board identifies
the board on the SCSI bus. To view the location of SW1, refer to the appropriate
McTi board drawing. The table below lists the SW1 dip switch settings.

NOTE 1:
Addresses 0, 1, 2, 6 & 7 should not be used by McIAS 1610 McTi boards.
Addresses 0, 1, 2, 4, 5, 6 & 7 should not be used by McIAS 1685 and 1607 McTi boards.
NOTE 2:
McIAS 1623/IP with McTi-24 Rev. 1 (and newer) boards requires that all SW1 dip switches
be set to the "off" position. McIAS 1623/IP board addresses are set by the backplane, not
SW1.
McTi-24 boards have two other switch banks: SW2 and SW3. SW3 is set at the
factory and should not be changed by the user. SW2 can be changed by the user for
T1 facility distance compensation. Refer to Section 2.6 for more information on SW2
settings.
