102 Check Point IP690 Security Platform Installation Guide
Do Not See Interfaces that Should be Present
Problem Local IP690 ports do not appear.
Solution Your NIC might be defective. See the Check Point Support Center at http://
support.checkpoint.com/ .

The problem could be with the slot on the PMC card carrier. Try installing the NIC in another
slot.
Common Ethernet Problems—Connectivity with Attached Device
Problem
No link light.
Solution You might have used the wrong cable. Use a crossover cable between an IP690 and
a host, and a straight-through cable between an appliance and a hub.
Problem Solid data and activity LED.
Solution
You might have set the wrong speed. Verify that the speeds match on each end of the
Ethernet connection (10 Mbps or 100Mbps).
Problem Port not enabled.
Solution Verify from the Interface page in Network Voyager that the interface port is
configured as active.
Problem High collision rate on the hub.
Solution Disconnect connections one at a time until the problem is localized to one computer
and troubleshoot further.
Unable to Ping Through Appliance—No Connectivity Between Ports
This section covers connectivity issues that are isolated within an IP690 or network.
Localize the problem by issuing pings to various network interfaces. Use tcpdump to help isolate
the problem. Use tcpdump to verify that a packet is leaving or entering a port.
Problem Interfaces not up.
Solution Ensure that all interfaces are up and active, as described in Chapter 3, “Performing
the Initial Configuration.”
