Operating HPE 16Gb FC switches
This chapter discusses switch power, LEDs, maintenance, and management.
Powering the switch on and off
• Power switches are located on the nonport side of the switch.
• If either the SN3000B or SN6000B 16Gb FC switch is mounted in a rack, you must remove the plenum
to access the power switches.
• Power is supplied to the switch as soon as the first power supply is connected and powered on.
• To power the switch off, power off the power supplies present by setting the AC power switch to
O . All
devices are returned to their initial state the next time the switch is powered on.
LEDs
The switch LEDs indicate system activity and status. There are three LED states: no light, a steady light,
and a flashing light. Flashing lights can be slow, fast, or flickering. The lights are green or amber.
The LEDs can flash green or amber 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.

show the LEDs on the port side of the switches. The port status LEDs for the FC ports are arranged left to
right, and correspond to the upper and lower ports in each pair. The LEDs on the nonport side of the
switches are shown in
