Check Point IP1280 Security Platform Installation Guide 127
Problem Wrong link speed.
Solution Verify that the port on the host and the port on the IP1280 are set for the same speed
(10 Mbps or 100 Mbps). An unblinking data and activity LED on a port is a good indication of a
speed mismatch.
Problem Duplex setting is wrong.
Solution Correct duplex setting.
Problem NIC, 6U PMC carrier, or ADP module is not installed correctly.
Solution Remove the NIC, 6U PMC carrier, or ADP module and reinstall it. Ensure that you
can tighten any retaining screws and that 6U PMC carrier or ADP module locking levers are
secured.
Do Not See Interfaces that Should be Present
Problem IP1280 ports do not appear.
Solution Your NIC or ADP module might be defective. Contact the appropriate Check Point
customer support site as listed in “Check Point Contact Information” on page 2.
Note
The problem could be with the interface slot. Try installing the NIC or ADP module in another
slot.

port is configured as active.
