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.

2. Open Servers and select the appropriate system.
3. In the content area, check the box for the appropriate Partition.
4. Select Tasks, then Operations, and then Manage Attention LED.

information:

Activating or deactivating 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:
v Identify LED for an enclosure If 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 in a drawer and verify that the MTMS corresponds to the drawer that requires the new adapter.
v Identify LED for a FRU associated with a specified enclosure If 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 Systems Management.
2. Select Servers.
3. In the content area, check the box for the appropriate system.
4. Select Tasks, then Operations, then LED Status, and then Identify LED.
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.
