Chapter 8: Troubleshooting
Testing link end hardware
Page 8-9
Ethernet LED blinks ten times then stays off
Meaning: There is no Ethernet traffic between the PSU and ODU.
Action: The fault may be in the LAN or ODU cable:
•
Confirm that Ethernet traffic is connected to the AC+DC injector LAN port, confirm the cable
is not faulty, replace if necessary.
•
If the LAN connection to the AC+DC Power Injector 56V is working, check the drop cable is
correctly wired using a suitable cable tester. Repeat the drop cable tests on page
Ethernet LED blinks irregularly
Meaning: If the Ethernet LED blinks irregularly, for example two rapid blinks followed by a
longer gap, this indicates that the ODU has booted in recovery mode. The causes may be:
installation wiring, or a corrupt ODU software load, or sufficient time has not been allowed
between a repeat power up.
Action: Refer to
Power LED is on, Ethernet LED blinks randomly
Meaning: Both LEDs are in their normal states, implying that the PSU is receiving power from
the AC/DC outlet and there is normal Ethernet traffic between the PSU and ODU.
Action: If, in spite of this, a fault is suspected in the link end hardware:
•
If the Ethernet connection to the network is only 100BASE-TX, when 1000BASE-T is
expected: remove the ODU cable from the PSU, examine it, and check that the wiring to
pins 4&5 and 7&8 is correct and not crossed.
