1.9.7 Unable to Verify the NIC Connection on Your PC
Symptom When connecting your PC to the ONS 15454 SDH, you are unable to verify the NIC
connection is working properly because the link LED is not illuminated or flashing.
Possible Cause The c cable is not plugged in properly.
Recommended Action Confirm both ends of the cable are properly inserted. If the cable is not fully
inserted due to a broken locking clip, the cable should be replaced.
Possible Cause The Category-5 cable is damaged.
Recommended Action Ensure that the cable is in good condition. If in doubt, use a known-good cable.
Often, cabling is damaged due to pulling or bending.
Possible Cause Incorrect type of Category-5 cable is being used.
Recommended Action If connecting an ONS 15454 SDH directly to your laptop/PC or a router, use a
straight-through Category-5 cable. When connecting the ONS 15454 SDH to a hub or a LAN switch,
use a crossover Category-5 cable. For details on the types of Category-5 cables, see the “Crimp
Replacement LAN Cables” procedure on page 1-139.
Possible Cause The NIC is improperly inserted or installed.
Recommended Action If you are using a Personal Computer Memory Card International Association
(PCMCIA)-based NIC, remove and insert the network interface card (NIC) to make sure the NIC is
fully inserted. If the NIC is built into the laptop/PC, verify that the NIC is not faulty.
