Ac LED
The upper LED (
1
) on the left side of the power supply, indicates that ac
current is present on the node.
Dc LED
The middle LED (
2
) to the left side of the power supply, indicates that
dc current is present on the node.
Power-supply error LED
The lower LED (
3
) to the left side of the power supply, indicates a
problem with the power supply.
Power, location, and system-error LEDs
The power, location, and system-error LEDs are housed on the rear of the SAN
Volume Controller.
The following terms describe the power, location, and system-error LEDs:
Power LED
This LED is the leftmost of the three LEDs and indicates the following
states:
Off One or more of the following are true:
v
No power is present at the power supply input.
v The power supply has failed.
v
The LED has failed.
On The SAN Volume Controller is on.
Flashing
The SAN Volume Controller is turned off but is still connected to a
power source.
Location LED
The SAN Volume Controller does not use this LED, which is the middle of
the three LEDs.
System-error LED
This LED is the rightmost of the three LEDs. The LED indicates that a
system board error has occurred. Light path diagnostics provide more
information about the error.
Ethernet-link LED
The Ethernet-link LED indicates that there is an active connection on the Ethernet
port.
An Ethernet-link LED is located beside each Ethernet port.
Ethernet-activity LED
An Ethernet-activity LED beside each Ethernet port indicates that theSAN Volume
Controller node is communicating on the Ethernet network that is connected to the
Ethernet port.
The operator-information panel LEDs refer to the Ethernet ports that are mounted
on the system board. If you install the 10 Gbps Ethernet card on a SAN Volume
Controller 2145-CG8, the port activity is not reflected on the activity LEDs.
