Activating and deactivating LEDs by using the HMC

Use this procedure to activate or deactivate LEDs by using Service Focal Point from the Hardware
Management Console (HMC).

Deactivating a system attention LED or partition LED by using the HMC

You can deactivate the attention LED for a system or logical partition if you decide that a problem is not
a high priority and you decide to repair the problem at a later time. The deactivation also allows the LED
to be activated again when another problem occurs.
To deactivate a system attention LED by using HMC, complete the following steps:
1. In the navigation area, open Systems Management.
2. Open Servers and select the required system.
3. In the content area, select the required partition.
4. Select Tasks > Operations > Deactivate Attention LED. A confirmation window is displayed with an
indication that there still might be open problems with the system.
5. Click OK to continue with the deactivation. A window is displayed that provides the details of the
system or partition, and a confirmation that the system or logical partition attention LED was
deactivated.

Activating or deactivating an identify LED by using the HMC

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 for 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 > Operations > LED Status > 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 and click 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.
