9. Connect the network cables

The type of network connections you will need to use depends on the types of switch modules you have installed in your 5400R zl2 Switch. See the documentation accompanying the modules for cabling configurations and procedures for those modules.

In general for all the modules, when a network cable from an active network device is connected to the switch, the Link LED for the switch port should go on. If the Link LED does not go on, use the table below to help solve the problem, and see the module documentation for troubleshooting procedures.

For more information on 40G port LED information, see the HPE Switch v3 zl2 module installation guide.



	NOTE: The 10/100/1000-T ports on the v2 zl or v3 zl2 Modules comply with IEEE 802.3x standard which includes the Auto MDI/MDI-X feature. This feature allows you to use straight-through twisted-pair cable for all of your twisted-pair network connections.

Condition

Diagnostic Tip

Port LED is still off when a cable is connected

Try the following procedures:

For the indicated port, verify both ends of the cabling, at the switch and the connected device, are securely connected.
Verify the connected device and switch are both powered on and operating correctly.
Verify you have used the correct cable type for the connection:
- for all twisted-pair connections, the RJ-45 connectors on the 5400R zl2 switches allow you to use either straight-through cable or crossover cable when the port is in the “Auto” configuration.
- for fiber-optic connections, verify the transmit port on the switch is connected to the receive port on the connected device, and the switch receive port is connected to the transmit port on the connected device.
For information on cables, see “Switch Ports and Network Cables” in the HPE 5400R zl2 Switches Installation and Getting Started Guide at www.hpe.com/networking/support.
Verify the port has not been disabled through a switch configuration change.
Verify the connection parameters in the configurations of the switch port and the connected device match. Mismatched configurations are a frequent cause of connection problems.
You can use the console interface, or, if you have configured an IP address on the switch, use the web browser interface, or Intelligent Management Center network management software to determine the state and configuration of the port and re-enable the port if necessary.
If the other procedures don’t resolve the problem, try using a different port or a different cable.
