Resolving Link Connectivity Problems

1. Check that external cables and/or optical modules are properly inserted.

2. Make sure the cables/modules are supported by the 10GbE PTM.

3. Log in to 10GbE PTM CLI and run the "show port link" command. Check the status of the

check again. Reboot the blade if the problem is not resolved.

b. If an Ethernet NIC or switch is connected to an 10GbE PTM external port but the link is down for the

10GbE PTM external port – check cables/modules connectivity in the external device and reboot the exter-

nal device if not resolved.
