Two-Port Fiber-Optic Gigabit Ethernet NICs Figure 20 shows the front panel details for the two-port long-range (1000 BASE-LX) fiber-optic Gigabit Ethernet NIC you can use in your IP1200. Figure 20 PMC Two-Port Long-Range Gigabit Ethernet NIC Link LEDs (solid green) Activity LEDs (blinking amber) 1000B-LX LINK ACT 00555 Ports After the power is turned on and the cables are connected, the Ethernet link LEDs on both the IP1200 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 For short-range NICs, to connect the fiber-optic Gigabit Ethernet NIC to other network components, use a multi-mode, 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 reach. For long-range NICs, to connect the fiber-optic Gigabit Ethernet NIC to other network components, use a single-mode, fiber-optic cable with an LC connector for each NIC interface. 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. Caution Depending on the product you order, one or more LC-to-SC cables are included with fiber-optic Gigabit Ethernet NICs. You can order additional cables from a cable vendor of your choice.Cables that connect to the Gigabit Ethernet NIC must be IEEE 802.3z compliant to prevent potential data loss. Performance Considerations If you are using two two-port fiber-optic Gigabit Ethernet NICs in an IP1200 Series, place one NIC in each of the two 6U PMC card carrier units to get maximum system throughput. Each 6U PMC card carrier unit has a separate PCI bus connection to the main system motherboard. In the configuration described here, each of the two fiber-optic two-port Gigabit Ethernet NICs access a separate PCI bus. IP1220 and IP1260 Security Platforms Installation Guide 65

After the power is turned on and the cables are connected, the Ethernet link LEDs on both the
IP1200 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
For short-range NICs, to connect the fiber-optic Gigabit Ethernet NIC to other network
components, use a multi-mode, 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
reach.
For long-range NICs, to connect the fiber-optic Gigabit Ethernet NIC to other network
components, use a single-mode, fiber-optic cable with an LC connector for each NIC interface.
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.
Caution
Depending on the product you order, one or more LC-to-SC cables are included with
fiber-optic Gigabit Ethernet NICs. You can order additional cables from a cable vendor
of your choice.Cables that connect to the Gigabit Ethernet NIC must be IEEE 802.3z
compliant to prevent potential data loss.
Performance Considerations
If you are using two two-port fiber-optic Gigabit Ethernet NICs in an IP1200 Series, place one
NIC in each of the two 6U PMC card carrier units to get maximum system throughput. Each 6U
PMC card carrier unit has a separate PCI bus connection to the main system motherboard. In the
configuration described here, each of the two fiber-optic two-port Gigabit Ethernet NICs access
a separate PCI bus.
