TROUBLESHOOTING
66 IPA Hardware Installation Guide
If neither RJ-45 Ethernet Status LED is illuminated, the physical Ethernet connection is faulty.
1 Verify that you are using the correct type of cable. See “Ethernet Cable Specification” on page 55.
2 Verify that the cable pinout matches the drive’s connector pin out. See “Ethernet Connector” on page 55.
3 Try swapping cables with Ethernet cables you know to be good. Even cables that do not meet the
Ethernet cable specification should cause the LEDs to illuminate.
4 If the LEDs still do not illuminate, look for Ethernet hardware problems.
Ethernet Network Status LED
If the Ethernet Network Status LED is off, there is no valid Ethernet communication.
