The 1000BASE-LX Module (3C17712) provides your
SuperStack
®
3 Switch 4900 series with four Gigabit
Ethernet fiber optic ports, each operating at full wire
speed and set to full duplex. This allows you to provide
connectivity between the Switch and remote workgroups
or to create a high capacity aggregated link backbone
connection.
The module requires management software version 1.2
or later to be installed on the Switch. For instructions on
upgrading management software, refer to the
documentation supplied with your Switch.
The Module conforms to the full duplex implementation
of the Gigabit Ethernet standard, IEEE 802.3z. Each port
provides a 1000 Mbps connections to another
1000BASE-LX device. Each port uses 62.5
