About the Switch
The Switch is a 10/100 Mbps Ethernet Switch, which consists of either:
■
24 10BASE-T/100BASE-TX ports or
■
48 10BASE-T/100BASE-TX ports
and:
■
Two 10BASE-T/100BASE-TX/1000BASE-T (10/100/1000) ports
■
Two SFP ports
The two 10/100/1000 ports are combination ports. When an SFP module
is inserted it has priority over the 10/100/1000 port of the same number
(25-26 on the Switch 3226, 49-50 on the Switch 3250). The
corresponding 10/100/1000 port is disabled when an SFP module is
present.
