Table 28 Ethernet Status LED Descriptions
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 40.
2.
Verify that the cable pin out matches the drive’s connector pin out. See
Ethernet Connector on pa
ge 40.
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.
