Connect The Network Cables - HP 5400R zl2 Series Nstallation And Getting Started Manual

Installing the HP 5400R zl2 Switches
Installation Procedures

8. 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 v3 zl2 module
installation guide.
Condition Diagnostic Tip

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.
See appendix B, "Switch Ports and Network Cables" for information on cables.
• 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.
