On The switch self test and initialization are in progress after the switch has been power
cycled or reset. The switch is not operational until this LED goes off. The Self Test LED
also comes on briefly when you “hot swap” a mini-GBIC into the switch; the mini-GBIC
is self tested when it is hot swapped.

for example an RJ-45 port, and the switch Fault LED will blink simultaneously.
Port LEDs

Link Indicates 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* (orange) simultaneously with the Fault LED, the
corresponding port has failed its self test.
Mode The operation of the Mode LED is controlled by the LED Mode select button, and the
current setting is indicated by the LED Mode indicator LEDs near the button. Press the
button to step from one view mode to the next. The default view is Activity (Act).
