Warnings: Please observe the following warnings, or damage to the equipment may result.
1. Remove the AZI II board from its carton. Ensure that power is disconnected from the card rack
assembly.
2. Before installation, set hex switch S1 (Board Address) and hex switch S2 (Board ID) as shown in the
system manual.
• The valid range of Board IDs is:
0x1 to 0xE (hex)

The following is an example of a Board Address and how it is derived:
Sample Board Address: 2 E 0
• The first digit must always be either a 2 or a 3. This corresponds to whether W1 is installed
(2), or is removed (3).
• The second digit is set by switch S1. It is a hexadecimal number ranging from 0 to F.
• The third digit is always zero.
3. Remove existing AZI II board from card rack assembly.
4. Align the new AZI II board into the upper and lower tracks for the slot.
