You are here to:	Go to:
Activate, deactivate, display state of a CEC or I/O enclosure identify LED.	MAP1250 Section-2
Test all LEDs for a CEC enclosure and the I/O enclosures it controls. Note: This also tests CEC enclosure control panel display character segments.	MAP1250 Section-3
All other storage enclosure/FRUs and rack power FRUs.	There are no utilities to manage these FRU LED indicators. Only the eServer™ CEC enclosure and I/O enclosure FRUs have LED utilities.

MAP1250 Section-2

Before you begin

Activate, deactivate, display state of a CEC or I/O enclosure identify LED.

About this task

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 enclosure, you must know the machine type, model, and serial number (MTMS) of the enclosure. To determine whether you have the correct MTMS for the enclosure that needs the new adapter, you can activate the LED for an enclosure and verify that the MTMS corresponds to the enclosure 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.

Procedure

To activate or deactivate an identify LED for an enclosure or FRU, follow these steps:

From the navigation area, click Storage Facility Management > storage facility > Server View > server.
From the bottom Task area, click Operations > LED Status > Identify LED. The Identify LED, Select Enclosure window opens and displays a list of enclosures and FRUs.
Select an enclosure or FRU and click Activate LED or Deactivate LED, depending on whether you want to activate or deactivate the Identify LED.

MAP1250 Section-3

Before you begin

Test all LEDs for a CEC enclosure and the I/O enclosures it controls.

About this task

This function shows whether any control panel indicators or display characters are burned out. In addition all LEDs on the CEC enclosure (front and rear) and I/O enclosures controlled by the CEC will be lit for 4 minutes.

Procedure

The CEC enclosure should be fully powered on.
Is the affected CEC in a 242x model 961 (8205-E6C or 8205-E6D)?
- Yes, continue with step 3.
- No, continue with step 4.
At the front of the affected CEC enclosure, press the blue release tab to the left and pull the control panel out to the service position. See Figure 1. When you are finished with this procedure, carefully slide the control panel into the control panel bay until it latches in place.
