View system attention LED information, light specific LEDs
to identify a system component, and test all LEDs on a managed system.
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. Individual
LEDs are located on or near the components. The LEDs are located either
on the component itself or on the carrier of the component (for example,
memory card, fan, memory module, or processor). LEDs are either green
or amber. Green LEDs indicate either of the following:
- Electrical power is present.
- Activity is occurring on a link. (The system could be sending
or receiving information.)
Amber LEDs indicate a fault or identify condition. If your system
or one of the components on your system has an amber LED turned on
or blinking, identify the problem and take the appropriate action
to restore the system to normal.
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 attach a cable to a specific I/O adapter, you can
activate the LED for the adapter that is a field replaceable unit
(FRU), and then physically verify where to attach the cable. This
can be especially useful when you have several adapters with open
ports.
You can deactivate a system attention LED or a logical partition
LED. For example, you might determine that a problem is not a high
priority and decide to repair the problem at a later time. However,
you want to be alerted if another problem occurs, so you must deactivate
the system attention LED so that it can be activated again if another
problem occurs.
Choose from the following options:
- Identify LED
- Displays the current Identify LED states for all the location
codes contained in the selected enclosure. From this task, you can
select a single location code or multiple location codes to operate
against and activate or deactivate the LED(s) by selecting the corresponding
button.
- Test LED
- Initiates an LED Lamp Test against the selected system. All LEDs
will activate for several minutes.
