DIAGNOSTICS
Switch Status Indicators
System activity and status can be determined through the activity of the
LEDs on the switch.
Note The LEDs may flash yellow during diagnostic tests; green, yellow,
or orange during POST. This is normal and does not indicate a problem
unless the LEDS do not return to a normal pattern after POST or the other
diagnostic tests are complete.
The HP Surestore FC 1Gb/2Gb Switch 16B includes the following LEDs:
• 16 port status LEDs on the SFP media side (above and to the left of each
port) to indicate the status of each port.
• 16 port speed LEDs on the SFP media side (above and to the right of
each port) to indicate the current link speed of each port.
• One switch power LED below the serial port on the SFP media side, to
indicate whether the switch is on and has successfully booted.
• Two power supply LEDs on the power supply side (one on each power
supply) to indicate the status of each power supply.
