3Com 5000 Switch User Manual


 
Setting the DIP Switches 3-5
Note that all of the DIP switch settings on the 24-Port module are
ignored if an appropriate CoreBuilder 5000 Distributed Management
Module (DMM 1.0 or later, for example) is already installed in the hub.
For this reason, we recommend that you use distributed management
commands, rather than the DIP switches, to configure the module. If
you'd like the module to access the DIP switch settings when using a
management module, issue the SET DEVICE DIP_CONFIGURATION
command from the management module.
If you do not have a CoreBuilder 5000 Distributed Management
Module installed in your hub, your hub’s configuration defaults to the
dip switch settings on the module.
If you are using a management module and do not plan to use the dip
configuration command, skip this section and proceed to the section
Installing the Module
in this chapter. Figure 3-1 provides an illustration
of the switch locations on the module.
Figure 3-1 24-Port Module and DIP Switch Location
Table 3-2 briefly describes the DIP switch settings. The complete
definition of each DIP switch function is contained in the section
Configuring the Module
later in this chapter.
