Blinking
Indicates that the port LEDs are displaying link information:
• if the port LED is on, the port is enabled and receiving a link indication
from the connected device.
• if the port LED is off, the port has no active network cable connected,
or is not receiving link beat or sufficient light. Otherwise, the port may
have been disabled through the switch console, the web browser
interface, or ProCurve Manager.
• if the port LED is blinking* simultaneously with the Fault LED, the
corresponding port has failed its self test.
Act Green On Indicates the port LEDs are displaying network activity information.
* The blinking behavior is an on/off cycle once every 1.6 seconds, approximately.
