After the power is turned on and the cables are connected, the Ethernet link LEDs on both the
IP561 and on the remote equipment illuminate to indicate the connection. As data is transmitted,
the activity LEDs on the appliance illuminate.
Fiber-Optic Gigabit Ethernet NIC Connectors and Cables
To connect the fiber-optic Gigabit Ethernet NIC to other network components, use a multimode,
fiber-optic cable with an LC connector for each NIC interface. You can use either 50 or 62.5
micron cable; 50 micron-type cable provides longer transmission length. The destination end of
the cable can be either LC or SC, depending on the type of connector required for the destination
Gigabit Ethernet device. You can also use a half-duplex LC-to-LC cable to loop back the
transmit port of an interface to the receiver port. LC and SC define the fiber-optic connector
types; LC connectors are smaller than SC connectors.
An LC-to-SC cable is included with single-port fiber-optic Gigabit Ethernet NICs, and two
LC-to-SC cables are included with two-port fiber-optic Gigabit Ethernet NICs. You can order
additional cables from a cable vendor of your choice.
Caution
Cables that connect to the Gigabit Ethernet NIC must be IEEE 802.3z compliant to
prevent potential data loss.
