The GBIC Module (3C17714) provides your
®
SuperStack
3 Switch 4900 Series with four Gigabit
Interface Convertor (GBIC) expansion ports. The Module
supports fiber Gigabit Ethernet short-wave (SX),
long-wave (LX) and long-haul (LH70) GBIC transceivers in
any combination. This offers you the flexibility of using
GBIC transceivers to provide connectivity between the
Switch and remote 1000 Mbps workgroups or to create
a high capacity aggregated link backbone connection.
The Module conforms to the full duplex implementation
of the Gigabit Ethernet standard, IEEE 802.3x.
The Module requires management software version 1.3
or later to be installed on the Switch. This is supplied on
the CD-ROM that accompanies the Module. For
instructions on upgrading management software, refer
to the documentation supplied with your Switch.
