3. When the transceiver is receiving
power and the stacking cable is
connected to another active switch,
the Link LED for the transceiver port
should be ON.
If the Link LED is off, see “Trouble-
shooting”, below.
Troubleshooting
The following problems may exist:
■ The Link LED for the transceiver is not on, even though the transceiver
is receiving power and the stacking cable is connected. Check the
following:
• Verify that both of the connected switches are powered on.
• Check the stacking cable and connections to make sure that the connec-
tions are secure, neither connector is damaged, and that none of the
connectors have a dust buildup or other object in the way that may cause
interference to the connection. If all connections are OK, try a different
cable.
• Try resetting or cycling power (turn the power off and then back on) on
the switch that is having the problem. If the transceiver was installed into
a Gigabit Stacking Module that was “hot swapped” into the Switch 2424M,
the resulting hot-swap self test does not test the transceivers. Resetting the
switch causes a complete self test to be performed, which does test the
transceivers.
■ The switch Fault LED and Link LED for the transceiver port are
flashing. Turn off the switch power and reinstall the transceiver into the
module and verify the transceiver screws are tightened. Turn the switch
power back on, and if the flashing persists, the transceiver may be faulty.
For additional troubleshooting, see the Gigabit Stacking Module Installation Guide
(J4130-90001). You can also use the switch's console interface, the switch’s web
browser interface, or HP Top Tools for Hubs & Switches to troubleshoot and
configure the Gigabit transceiver port. See the switch's Management and Configu-
ration Guide for more information.
If you are still having trouble, see the “Customer Support Services” on page 6.
