Configuration Switches
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 26 for binary switch
settings). Figure 65 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.
