About the Switch
3870
The Switch 3870 24 port unit is a mixed media device which consists of:
■ 24 10BASE-T/100BASE-TX/1000BASE-T RJ-45 ports and
■ Four 10/100/1000BASE-T/1000BASE-X SFP ports
The Switch 3870 48 port unit is a mixed media device which consists of:
■ 48 10BASE-T/100BASE-TX/1000BASE-T RJ-45 ports
■ Four 10/100/1000BASE-T/1000BASE-X SFP ports
The four highest numbered RJ-45 ports (21–24 on the 24-port Switch,
45–48 on the 48-port Switch) and the SFP ports are combination ports.
When an SFP module is inserted it has priority over the RJ-45 port with
the same number and the RJ-45 port is disabled.
For information about using the software features of the Switch, refer to
the “Switch Management Interface Reference Guide” on the CD-ROM
that accompanies the Switch.
