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 8200 zl switch must be compatible
with these standards.To verify your cable is compatible with these standards,
use a qualified cable test device.
HP networking also offers a wire testing service. Contact your HP authorized
LAN dealer or your local HP 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.

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 HP Web site.
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.

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
