Activating an identify LED for an enclosure or server by using the HMC
Learn how to activate an identify LED for an enclosure or server by using the Hardware Management
Console (HMC).
About this task
The system provides several LEDs that help you to identify various components in the system, such as
enclosures or field-replaceable units (FRUs). For this reason, they are called identify LEDs.
If you want to add a part to a specific enclosure or server, you need to know the machine type, model, and
serial number (MTMS) of the enclosure or server. To determine whether you have the correct MTMS for
the enclosure or server that needs the new part, you can activate the LED for an enclosure or server and
verify that the MTMS corresponds to the enclosure or server that requires the new part.
Procedure
1. In the navigation area, click the Resources icon
2. Click the server name for which you want to activate the identify LED.
3. Click System Actions > Attention LED > Identify Attention LED. The Identify Attention LED, Select
Enclosure window is displayed.
4. To activate an identify LED for an enclosure or server, select an enclosure or server and then click
Activate LED. The associated LED is turned on.
Finding the part location code and LED support status
You can use location codes for the server you are working with to find the part location code to identify
the system that requires support.
About this task
To find the location code and to determine if there is an LED to help you identify the system that requires
support, complete the following steps:
Procedure
1. Select the server you are working on to see the location codes:
• 5105-22E, 9008-22L, 9009-22A, 9009-22G, 9223-22H, or 9223-22S locations (http://
