I. Front panel
An S5100-50C-EI Ethernet switch provides 48 x 10/100/1000Base-T autosensing
Ethernet ports, four 1000Base-X SFP ports, and one console port on the front panel. An
SFP port and its corresponding 10/100/1000Base-T autosensing Ethernet port form a
Combo port. That is, only one of the two ports forming the Combo port can be used at a
time. Table 1-2 shows the mapping relations between the ports forming the Combo port.
