5 About IP1200 Series Appliance Network Interface Cards After the power is turned on and the cables are connected, the Ethernet link LEDs on both the IP1200 Series and on the remote equipment illuminate to indicate the connection. Note The Link LED on the NIC is bicolored. A green LED indicates a 1 Gbps link speed, and a yellow LED indicates a 10/100 Mbps link speed. As the NIC transmits data, the activity LEDs on the appliance illuminate. Performance Considerations If you are using two two-port or four-port copper 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 copper Gigabit Ethernet NICs access a separate PCI bus. For the IP1200 Series appliance, any two NICs installed on a single PMC carrier both operate at the PCI frequency of the least capable NIC installed. Copper Gigabit Ethernet NIC Connectors and Cables The IP1200 Series receptacles are RJ45 connectors. Caution Cables that connect to the Gigabit Ethernet card must be IEEE 802.3 compliant to prevent potential data loss. To connect to a 1-Gbps hub, switch, or router, use a straight-through RJ-45 cable (Cat 5 type cable, or as required by your network configuration). Note Certain circumstances might require shielded Cat 5 Ethernet cables to meet Class B emissions requirements. In Figure 17, the RJ-45 cable output connector is numbered from right to left, with the copper pins facing up and toward you. 62 IP1220 and IP1260 Security Platforms Installation Guide

IP1220 and IP1260 Security Platforms Installation Guide
After the power is turned on and the cables are connected, the Ethernet link LEDs on both the
IP1200 Series and on the remote equipment illuminate to indicate the connection.
Note
The Link LED on the NIC is bicolored. A green LED indicates a 1 Gbps link speed, and a
yellow LED indicates a 10/100 Mbps link speed.
As the NIC transmits data, the activity LEDs
on the appliance illuminate.
Performance Considerations
If you are using two two-port or four-port copper 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 copper Gigabit Ethernet NICs
access a separate PCI bus.
For the IP1200 Series appliance, any two NICs installed on a single PMC carrier both operate at
the PCI frequency of the least capable NIC installed.
Copper Gigabit Ethernet NIC Connectors and Cables
The IP1200 Series receptacles are RJ45 connectors.
Caution
Cables that connect to the Gigabit Ethernet card must be IEEE 802.3 compliant to
prevent potential data loss.
To connect to a 1-Gbps hub, switch, or router, use a straight-through RJ-45 cable (Cat 5 type
cable, or as required by your network configuration).
Note
Certain circumstances might require shielded Cat 5 Ethernet cables to meet Class B
emissions requirements.

pins facing up and toward you.
