1.2.9 Enclosure DIP Switches
Figure 1-13: Enclosure DIP Switches
DIP switches are located on the upper left corner of enclosure rear panel. The first tree
switches determine an enclosure ID and should always be kept at their default, “0-0-0.”
The two (2) switches marked as #7 and #8 have no function. The #4 switch is for
controlling the onboard hub across the host ports on partner controllers, to enable/disable
the onboard bypass. Switch #4 is only applicable in a dual-controller configuration.
Switches #5 and #6 control host channel 4G or 2G speed.
When the onboard hub is enabled, host channels on the partner controllers will be
combined, e.g., Channel 0 on Controller A and Channel 0 on Controller B combined into
a host loop. Using the onboard hub enables fault-tolerant host links without the use of
expensive FC switches in a DAS (Direct Attach Storage) topology.
The configuration options for setting the DIP switches is fully discussed in Chapter 4.
