The network port
for which the Link
LED is blinking 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 blinking 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 which is on the HP networking Web site. See
details.
For more information on 40G port self-test or initialization failure, see v3 zl2 module
installation guide.
