SAN Volume Controller 2145-DH8 operator-information panel

Edit online

The operator-information panel contains buttons and indicators such as the power-control button, and LEDs that provide system information.

Figure 1 shows the operator-information panel for the SAN Volume Controller 2145-DH8 .

This figure shows the SAN Volume Controller 2145-DH8 operator-information panelwith the components identified.
  •  1  Power-control button and power-on LED
  •  2  Ethernet icon
  •  3  Identify button and LED
  •  4  Release latch for the light path diagnostics panel
  •  5  Ethernet activity LEDs
  •  6  Check log LED
  •  7  System-error LED
Note: If the node has more than four Ethernet ports, activity for ports 5 and above is not indicated by the Ethernet activity LEDs on the operator-information panel.

Power LED

The green power LED indicates one of the following power conditions.

Off
One or more of the following are true:
  • No power is present at the power supply input.
  • The power supply has failed.
  • The LED has failed.
On
The node is turned on.
Blinking
The node is turned off, but is still connected to a power source.

Power button

The power button turns main power on or off for the SAN Volume Controller .

  • To turn on the power, press and release the power button. You must have a pointed device, such as a pen, to press the button.
  • To turn off the power, press and release the power button. For more information about how to turn off the SAN Volume Controller node, see MAP 5350: Powering off a SAN Volume Controller node.
Attention: When the node is operational and you press and immediately release the power button, the SAN Volume Controller writes its control data to its internal disk and then turns off. This process can take up to 5 minutes. If you press the power button but do not release it, the node turns off immediately without writing the SAN Volume Controller control data to disk. Service actions are then required to make the SAN Volume Controller operational again. Therefore, during a power-off operation, do not press and hold the power button for more than 2 seconds.

Ethernet activity LEDs

The Ethernet activity LEDs indicate that the server is transmitting to or receiving signals on the Ethernet ports. Each LED corresponds to a specific port, and indicates traffic to or from the Ethernet LAN that is connected to that port.

Ethernet activity LED 4 is for activity on the Technician port. Use the Service Assistant GUI to see activity on this port.

Identify button and LED

Press the identify button to make the LED blink. The identify LED on the back of the 2145-DH8 also blinks.

In the management GUI, select Monitoring > System. On the System -- Overview page, select the directional arrow near the node that you want to turn on the identify LED for. On the Node Details page, select Node Actions > Identify. The Identify LED turns on.

System error LED

The amber system-error LED indicates that a system-board error occurs. It lights up if the hardware detects a fatal error that requires a new field-replaceable unit (FRU).

Note: See MAP 5800: Light path to help you isolate the faulty FRU.

System information LED

The system-information LED indicates that a noncritical event occurs. Check the light path diagnostics panel and the event log. Light path diagnostics are described in more detail in the light path maintenance analysis procedure (MAP).

Release latch

The release latch gives you access to the light-path diagnostics panel, which you can use to determine the location of a problem.

After you press the release latch on the operator-information panel, you can slide the light-path diagnostics panel out to view the LEDs. The LEDs indicate the type of error that occurs. See MAP 5800: Light path for more detail.

To retract the panel, push it back into the node and snap it into place.
