A module was installed
When you “hot swap” modules in the switch slot, if you install a different module
➌
in the slot that is a
type than the one that was previously installed in the slot, you must reset the
different type than the
switch so the switch processor can properly initialize and configure the new
previously installed
module type. The flashing LED informs you that this change of module types has
module, and the switch
occurred. The module will not work properly until the switch is reset, as indicated
has not yet been reset.
by all the module’s LEDs staying on until the switch is reset.
See “Resetting the Switch” on
page 16
.
The network port for
➍
which the Link LED is
flashing has
experienced a self test
or initialization failure.
During the module self test (described in tip number 2), each network port is also
tested. If the port self test fails, the individual port is not usable, but the rest of
the ports on the module, which have passed their self test, will continue to
operate normally.
If the error has occurred on a
mini-GBIC
that you have installed in the mini-GBIC
gl Module, ensure it is one of the supported mini-GBICs. The HP ProCurve mini-
GBICs that are supported, as of the printing of this manual, are listed on page 1.
Use only the supported HP ProCurve mini-GBICs. If it is a supported mini-GBIC,
it may have failed. Try removing and reinstalling the mini-GBIC and it will be
tested again. If the fault indication reoccurs, the mini-GBIC is faulty and must be
replaced.
If the error has occurred on an
transceiver
that you have installed in the Gigabit
Transceiver gl Module, the transceiver itself may be faulty. Try removing and
reinstalling the transceiver and it will be tested again. If the fault indication
reoccurs, the transceiver is faulty and must be replaced.
If the error has occurred a
twisted-pair port
or
100-FX port
on one of the other
modules, try reinstalling the module. If the port fault indication reoccurs, and you
need to be able to use the port, you will have to replace the module. In the mean
time, all the other module ports will operate normally.
The network port for
➎
which the Link LED is
flashing has been
disabled because port
security has been
configured on the
switch and a security
violation has been
detected on the port.
For the Port Security feature, you can configure the switch so that whenever a
security violation is detected on a port, the switch will disable the port. When a
port is disabled by this feature, the port Link LED will be continuously flashed at
the fast rate of 0.8 seconds per cycle. The flashing continues until you clear the
security violation through the switch console. In the console, you can view the
identity of the connected device that committed the security violation.
Once the security violation is cleared, you must re-enable the port through the
console.
For more information on the Port Security feature, see the
Management and
Configuration Guide
that is on the documentation CD-ROM that came with your
switch.
