Tip
Letter Problem
J
The mini-GBIC or
SFP installed in the
mini-GBIC slot for
which the Link LED
is flashing is an
invalid or
unsupported
transceiver.
K
In the slot
corresponding to
the letter that is
flashing, a module
was installed that is
a different type
than the previously
installed module,
and the switch has
not yet been reset.
L
The network port
for 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.
Ensure you have installed a model B or greater ProCurve mini-GBIC or SFP in the
slot. Model A mini-GBICs are not supported in the Series 4200vl Switches.
If the mini-GBIC or SFP is a model B or greater, then the LED pattern indicates the
transceiver is unsupported in the version of software currently running on the
switch. As ProCurve introduces new transceivers for the vl switches you may have
to update the switch with new operating code that supports the new transceiver.
The documentation that came with the transceiver will indicate which version of the
operating code is needed to support the transceiver. The latest code can be
downloaded from the ProCurve Web site at www.procurve.com. Download the new
code and retest the transceiver by rebooting the switch with the new software.
When you "hot swap" modules in the switch slots, if you install a different module
type than the one that was previously installed in the slot, you must reset the switch
so the switch processor can properly initialize and configure the new module type.
The flashing LED informs you that this change of module types has occurred. The
module will not work properly until the switch is reset.
You can reset the switch by any of these methods:
• pressing the Reset button.
• power cycling the switch.
• selecting the reset or reboot option from the console, web browser interface, or
ProCurve Manager.
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 for your switch, available on the ProCurve Web site.
