controller module A (Fibre Channel connector J3) and Host ID BD2 SW2 selects the address for controller module B (Fibre Channel connector J4). Each Fibre Channel Host ID DIP switch contains a bank of seven switches that select the address using a binary value, 000 0000 (0) through 111 1111 (126). To set an address, set the switches in the up position for "1" or down for "0" (refer to Table 20 for binary switch settings). Figure 56 illustrates the loop ID switch set to 42 (0101010). Note The factory default Fibre Channel Host ID loop address settings for controller A (BD1) is 5, and the default for controller B (BD2) is 4. If you must change the default values, make sure you select a unique value for each ID. The Fibre Channel Host ID loop address settings must be unique for each controller, regardless of the external Fibre Channel topology. 146 Configuration Switches
