Chapter 3. Operating the SAN06B-R

The switch is engineered for reliability and requires no routine operational
maintenance. However, this chapter provides information about determining the
overall status of the system and each of its components using LEDs and CLI
commands.
This chapter provides the following information:
v "LED activity"
v "Interpreting POST results" on page 30
v "Diagnostics and troubleshooting" on page 31

LED activity

System activity and status can be determined through the activity of the LEDs on
the switch.
There are three possible LED states:
v No light
v Flashing
v Steady light
Active lights are either green or amber. The status LEDs might display solid amber
or flash during boot, POST, or other diagnostic tests. This is normal; it does not
indicate a problem unless the LEDs do not indicate a healthy state after all boot
processes and diagnostic tests are complete.

LEDs on the port side of the switch

The port side of the switch has the following LEDs:
v One system status LED (above) on the left side.
v One power status LED (below) on the left side.
v Management Ethernet port speed and activity LEDs.
v One port status LED for each Fibre Channel port on the switch. The port LEDs
v One port status LED for each optical GbE port.
v Two LEDs for each copper GbE port, one activity/status LED and one fault
