Testing Twisted-Pair Cabling

If you think the cable should work but still isn’t working, it may not be

compatible with the IEEE 802.3 Type 10Base-T, 100Base-TX, or 1000Base-T

standards, as appropriate for the switch port type that the cable is connected

to. The twisted-pair cables attached to the Series 5400zl Switches must be

compatible with these standards.To verify your cable is compatible with these

standards, use a qualified cable test device.

ProCurve Networking also offers a wire testing service. Contact your

ProCurve authorized LAN dealer or your local ProCurve Networking sales

office for more information.

Testing Switch-to-Device Network Communications

You can perform the following communication tests to verify the network is

operating correctly between the switch and any connected device that can

respond correctly to the communication test.

■ Link Test -- a physical layer test that sends IEEE 802.2 test packets to any

device identified by its MAC address

■ Ping Test -- a network layer test used on IP networks that sends test

packets to any device identified by its IP address

These tests can be performed through the switch console interface from a

terminal connected to the switch or through a telnet connection, or from the

switch’s web browser interface. See the Management and Configuration

Guide which is on the ProCurve Web site. See page 5-1 for details.

These tests can also be performed from an SNMP network management

station running a program that can manage the switch, for example, ProCurve

Manager.

Testing End-to-End Network Communications

Both the switch and the cabling can be tested by running an end-to-end

communications test -- a test that sends known data from one network device

to another through the switch. For example, if you have two PCs on the

network that have LAN adapters between which you can run a link-level test

or Ping test through the switch, you can use this test to verify the entire

communication path between the two PCs is functioning correctly. See your

LAN adapter documentation for more information on running the a link test

or Ping test.
