visible on the front panel as shown in Table 2. This switch will allow for the proper connection
regardless of the cable type configuration.
When connecting to end devices, the X-over switch should be selected to reflect the type of cabling
used. (i.e. Straight through is selected when using straight through cabling, X-over is selected
when using crossover cabling)
