ART NUMBER 00041369-002 REV. B
System LEDs
The System LEDs indicate the switch’s status, independent of the port LEDs.
Port LEDs
The Port LEDs indicate the port’s status. Each port has two LEDs:
SFP Status LED
Port Bypassed LED
System LEDs Indication
Fault
(yellow LED)
• When lit, one or more of the ports has failed or the internal temperature has
exceeded acceptable levels.
• When flashing, all ports are operational but another error has occurred.
Errors appear in an event log. The level of error severity that will cause
flashing to start can be controlled using the config sys fault command in the
CLI. The default is level 3, Critical.
Note: Whether lit or flashing, the switch will continue to operate. Switch
functionality may be impaired depending on the event that triggered the
Fault LED. Regardless of the cause, the switch requires immediate
attention.
Power
(green LED)
When lit, the switch is plugged in and the internal power supplies are functional.
2 Gb/s
(green LED)
When lit, the switch is set to operate at a speed of 2 Gb/s. When off, the switch
is set to 1 Gb/s.
Switch
Operational
(green LED)
• When lit, indicates that the switch has completed initialization for ports with
inserted SFPs and that the switch is operational.
• When flashing, the switch has been configured for multiple zones, and one or
more zones are up with at least one zone down.
If no zones (excluding hard zones) are operational, the LED turns off.
SFP Status
