The system provides several LEDs that help 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.
1.
Choose one of the following navigation options depending on the interface type of the HMC:
v
If you are using an HMC Classic or HMC Enhanced interface, complete the following steps:
a.
In the navigation area, click Systems Management > Servers.
b.
In the content pane, select the server.
c.
Click Tasks > Operations > LED Status > Identify LED. The Identify LED, Select Enclosure
window is displayed.
v
If you are using an HMC En Tech Preview (Pre-GA) or HMC E interface,
complete the following steps:
a.
In the navigation area, click the Resources icon
, and then click All Systems.
b.
Click the server name for which you want to activate the identify LED.
c.
Click System Actions > Attention LED > Identify Attention LED. The Identify Attention LED,
Select Enclosure window is displayed.
2.
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 and
whether there is Identify LED support.
To find the location code and to determine if there is identify LED support, complete the following steps:
1.
Select the server you are working on to see the location codes:
v
5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A locations (http://www.ibm.com/
support/knowledgecenter/POWER8/p8ecs/p8ecs_83x_8rx_loccodes.htm)
v
8247-42L, 8286-41A, or 8286-42A locations (http://www.ibm.com/support/knowledgecenter/
POWER8/p8ecs/p8ecs_82x_84x_loccodes.htm)
v
8408-44E or 8408-E8E locations(http://www.ibm.com/support/knowledgecenter/POWER8/p8ecs/
p8ecs_85x_loccodes.htm)
v
9080-MHE, 9080-MME, 9119-MHE, or 9119-MME locations(http://www.ibm.com/support/
knowledgecenter/POWER8/p8ecs/p8ecs_87x_88x_loccodes.htm)
2.
Record the location code.
3.
Refer to the field replaceable unit (FRU) location table, Identify LED column to see if the word Yes
(there is an identify LED) or No (there is not an identify LED) appears.
4.
Select from the following options:
v
If the part has an identify LED, refer to the applicable procedure:
– If you are using IBM PowerKVM, see “Identifying a part by using the ASMI” on page 132.
– If your system is at runtime state, see “Identifying a part by using the operating system or
– If your system is at standby power state, see “Identifying a part by using the ASMI” on page
