In-Depth Information
Some chassis provide a single 10-pin header connector for the front panel switch/LED
connections, but most provide individual 2-pin connectors for the various functions. If
2-pin connectors are used, they are connected as shown in Figure 4.30 . Note that you can
easily replace the multiple 2-pin connectors with a single 10-pin connector; some chassis
even include an adapter for this purpose.
Figure 4.30 Standard front panel switch/LED connections using 2-pin connectors.
The 2-pin connections to a standard 10-pin front panel switch/LED connector are shown
in Table 4.37 .
