Emulex 355 Port LEDs, System LEDs Indication, SFP Status Port Bypassed, Green LED Yellow LED

INSPEED™ SAN STORAGE SWITCH MODEL 355	CHAPTER 2 SWITCH INSTALLATION
USER’S GUIDE

System LEDs	Indication
Fault	• When lit, one or more of the ports has failed or the internal temperature has
(yellow LED)	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	When lit, the switch is plugged in and the internal power supply is functional.
(green LED)
2 Gb/s	When lit, the switch is set to operate at a speed of 2 Gb/s. When off, the switch is set to
(green LED)	1 Gb/s.
Switch	• When lit, indicates that the switch has completed initialization for ports with inserted
Operational	SFPs and that the switch is operational.
(green LED)	• 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.
Port LEDs

The Port LEDs indicate the port’s status. Each port has two LEDs:

•SFP Status LED

•Port Bypassed LED

SFP Status

Port Bypassed

SFP Status	Port Bypassed
LED	LED	Indication
(green LED)	(yellow LED)
Off	Off	Normal port operational status when an SFP is not installed.
Off	On or Flashing	The port is bypassed due to a faulty or improperly seated SFP. After
		fixing this problem, power may need to be cycled before the LED
		indication will change.
Flashing	Off	Activity. Data is being transferred between the port and device.
On	Off	Normal operation but no activity. Port and device are fully operational.
On	Flashing	Manually bypassed. A port can be manually bypassed using the Web
		Manager’s Bypass Port feature.
On	On	Bypassed. SFP is installed but the port is not receiving a valid signal or
		is receiving an F8 Failure notification from the attached device.
Flashing	Flashing	Beaconing. This is set manually using the Web Manager or CLI.
