LED Overview
5-
This chapter provides an overview of the LED indications available in the
system. It contains the following sections:
• “Unit Status LEDs”
• “Power Supply LEDs”
• “10 Gigabit Ethernet Port LEDs”
• “10/100/1000 Mbps Port LEDs”
• “Local Management Port LEDs”
• “Sync Port”
All interfaces on the 3930 are accessible from the faceplate of the unit. With
the exception of the Console and Alarm ports, all the interfaces have
integrated LEDs which provide status information for the port.
Note: The connector for the Console port has LEDs, however these LEDs
are not used. They will not light at any time.
Figure 1-1 on page 1-3 shows the faceplate of the unit and identifies the
locations of the different ports.
System Reset Button and LED Behavior
Pressing the reset button will turn on all of the LEDs in the system. If you
initiate a hard reset (pressing the reset button for 3 seconds or longer) all of
the LEDs will flash simultaneously to acknowledge that a reset to factory
defaults has been initiated.
If this is a 3930 Sync + External Timing system, and the system was in a non-
responsive state when the reset button was depressed, the following LED
indications will occur after the reset button is released:
• the port LEDs will count down while the state dump is in progress. The
count down will start with all port LEDs on, and will turn off LEDs in
sequence until they are all off. This sequence will repeat until the state-
dump has completed.
• when the system reboots, the LEDs proceed through the normal startup
behavior with the STAT LED blinking green until the system has initialized.
