• Check dmesg/syslog output and look for error messages pertaining to gelan/igelan.
Also, check nettl log messages. If errors, check card installation and reset and/or
reseat card.
• Verify LEDs. If 1000Base-SX link LED = OFF or for gelan, 1000Base-T all speed
LEDs = ON, check card installation and reset and/or reseat card. If LEDs are then
displayed correctly, continue to Link Level Test.
• If 1000Base-T all speed LEDs = OFF or for gelan, 1000Base-SX Link LED =
Flashing, check for incorrect or faulty network cable or connector. Ensure that
switch is capable of 1000 Mbps operation. Ensure that the switch (or immediate link
partner) and card are set to same autonegotiation settings. Then go to Configuration
Tests. Otherwise, if 1000Base-SX link LED or one of 1000Base-T speed LEDs is on,
continue to Link Level Test.
NOTE Refer to Table C-1, “LED Description and Status for 1000Base-SX” and Table C-2, “LED
Description and Status for 1000Base-T” for LED status.
On a 1000Base-SX card, if both Link and Activity LEDs are on and there is no network
connectivity, it could mean that the I/O cage is not seated well. Remove and reseat the
entire PCI I/O cage and reboot.
