Activate or deactivate identify LED 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:

• 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.
• 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 the server you are working on by checking the box next to its name.
3. Open Operations.
4. Open LED Status.
5. Select Identify LED. The Identify LED, Select Enclosure window opens.
6. 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.
7. To activate or deactivate an identify LED for a FRU, select an enclosure from the table, select Selected -> List FRUs.
8. 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.
