Testing Twisted-Pair Cabling; Testing Switch-To-Device Network Communications - HP J4093A Installation Manual

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 or 100Base-TX standards. The
twisted-pair cables attached to the Switch 1600M and 2424M must be compat-
ible with these standards. To verify that your cable is compatible with these
standards, use a qualified cable test device.
HP also offers a wire testing service. Contact your HP-authorized LAN dealer
or your local HP sales office for more information.
N o t e
Make sure that you are using the correct cabling type for each connection.
The switch 10 Mbps and 100 Mbps UTP ports are all wired as MDI-X. For
connecting end nodes and other MDI-type devices, use "straight-through"
cable. For connecting hubs, other switches, and other MDI-X devices, use
"crossover" cable. See appendix B, "Cables and Connectors" for the pinouts
for these cables.

Testing Switch-to-Device Network Communications

You can perform the following communication tests to verify that 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 that came with your switch for more information.
These tests can also be performed from an SNMP network management
station running a program that can manage the switch, for example, HP
TopTools for Hubs & Switches.
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
