Cause and Action
When connecting a cable to the management port, LNK/ACT LED
(green) may not turn on because of the following causes.
The power of the HUB, switch, or server to connect to has not been
turned on.
The power supply of the HUB, switch, or server to connect to is at
fault.
The cable type is wrong.
A cross cable and straight cable are not recognized automatically. Use
a cable following the predetermined connection method.
The Speed and Duplex settings do not match.
Auto Detect is set as default. Since connecting to a device in Full
Duplex mode could cause abnormal operation, set Auto Detect or Half
Duplex to the device to connect.
(To set Full Duplex, ask your sales or maintenance service agent.)
Depending on the type of hub, it may remain off or it may blink.
This is not a fault.
SPEED LED (Green/Orange) is on when connection is established
through the disk array unit monitoring protocol with a cable connected to
the management port. If the cable is removed from the unit, SPEED LED
briefly remains on.
Cause and Action
This is not a fault.
This indicates that AC input is being supplied to the unit and DC output is
in normal operation.
AC input is not being supplied.
Check whether the power supply cable is correctly connected. If the
cable is correctly connected, replace the power supply.
This indicates that the power fan error was detected or the temperature
within the power supply reached the warning value (the detected
temperature was more than 55 degrees Celsius (131°F)).
274
The unit has dual power supply configuration.
Therefore, SERVICE LED turns on when FAULT
LEDs of both PS0 and PS1 are on.
