HP B-series 16Gb FC Switches Hardware Reference Guide

3 Operating HP 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 HP 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.
Figure 27 (page 47) and Figure 29 (page 50) 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 Figure 28 (page 48)
and Figure 30 (page 50).
