Deactivate a system attention LED or partition LED

You can deactivate a system attention LED or a logical partition LED. For example, you might determine that a problem is not a high priority and decide to repair the problem at a later time. However, you want to be alerted if another problem occurs, so you must deactivate the system attention LED so that it can be activated again if another problem occurs.
  1. In the navigation area, open Service Applications.
  2. Select Service Focal Point.
  3. Select Service Utilities. The Service Utilities window is displayed.
  4. Select one of the managed systems, and select System Attention LED from the Selected menu. The system attention LED window opens. The selected system and its LED state are displayed in the upper part of the window. The logical partition and its LED state are displayed in the lower part of the window. From the system attention LED window, you can deactivate both the system attention LED and the logical partition LED.
  5. Select Deactivate System Attention LED from the Action menu. A confirmation window is displayed that provides the following information:
    • A verification that the system attention LED was deactivated.

Activate or deactivate identify LED

The system provides several LEDs that help identify various components, such as enclosures or field replaceable units (FRUs), in the system. For this reason, they are called Identify LEDs.

You can activate or deactivate the following types of identify LEDs:
  • Identify LED for an enclosureIf you want to add an adapter to a specific drawer (enclosure), you need to know the machine type, model, and serial number (MTMS) of the drawer. To determine whether you have the correct MTMS for the drawer that needs the new adapter, you can activate the LED for a drawer and verify that the MTMS corresponds to the drawer that requires the new adapter.
  • Identify LED for a FRU associated with a specified enclosureIf you want to hook up a cable to a specific I/O adapter, you can activate the LED for the adapter which is a field replaceable unit (FRU), and then physically check to see where you should hook up the cable. This is especially useful when you have several adapters with open ports.

To activate or deactivate an identify LED for an enclosure or FRU, follow these steps:

  1. In the navigation area, open Service Applications.
  2. Select Service Focal Point.
  3. Select Service Utilities. The Service Utilities window is displayed.
  4. Select one of the managed systems and select Selected > Identify LED Processing. The Identify LED, Select Enclosure window opens.
  5. To activate or deactivate an identify LED for an enclosure, select an enclosure from the table, and click either Activate LED or Deactivate LED. The associated LED is either turned on or off.
  6. To activate or deactivate an identify LED for a FRU, select an enclosure from the table, select Selected > List FRUs.
  7. Select one or more FRUs from the table, and click either Activate LED or Deactivate LED. The associated LED is either turned on or off.
