Activating or deactivating an identify LED by using the management
console
You can activate or deactivate an identify LED for components attached to the system from the Hardware
Management Console (HMC).
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.
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 connect 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, 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:
1.
In the navigation area, click Systems management > Servers.
2.
To enable the tasks for that server, select the required server name.
3.
From the Tasks menu, click Operations > LED Status > Identify LED. The Identify LED, Select
Enclosure window is displayed.
4.
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.
5.
To activate or deactivate an identify LED for a FRU, select an enclosure from the table, and then
click Selected > List FRUs.
6.
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.
v
If you are using an HMC E interface, complete the following steps:
1.
In the navigation area, click the Resources icon
, and then click All Systems.
2.
To view the actions for that server, select the required server.
3.
In the navigation area, click System Actions > Attention LED > Identify Attention LED. The
Identify Attention LED, Select Enclosure window is displayed.
4.
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.
5.
To activate or deactivate an identify LED for a FRU, select an enclosure from the table, and then
