SFP Ports

The four SFP ports support fiber Gigabit Ethernet
short-wave (SX) and long-wave (LX) SFP transceivers in
any combination. This offers you the flexibility of using
SFP transceivers to provide connectivity between the
Switch and a 1000 Mbps core network.
When an SFP port is in operation, the corresponding
10/100/1000BASE-T port is disabled.
