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
