HP 5400R zl2 Installation and Getting Started Guide

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.
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.

Switches
10. (Optional) Connect to the Management Console of
the Switch
The 5400R zl2 switches have a full-featured, easy to use console interface for
performing the following tasks:
■ Monitor switch and port status and observe network activity counters
■ Modify the switch’s configuration
■ Read the event log and access diagnostic tools to help in troubleshooting
■ Download new software to the switch
■ Add passwords and other security features to control access to the switch
from the console, web browser interface, and network management
stations
The console can be accessed through these methods:
■ Out-of-band: Connect a PC or VT-100 terminal, to be used as a console,
directly to the switch using the serial cable that comes with the 5400R zl2
switches. If the PC or terminal has a 25-pin serial connector, you can use
a readily available 9-pin to 25-pin serial cable, or attach a 9-to-25 pin
straight-through adapter to the PC end of the cable.
