the ownership of the media tray has been transferred to the blade server. It can take approximately 20
seconds for the operating system in the blade server to recognize the media tray.
If there is no response when you press the media-tray select button, you can use the advanced
management module web interface to determine whether local control has been disabled on the blade
server.
Note: The operating system in the blade server must provide USB support for the blade server to
recognize and use the removable-media drives.
Activity LED
When this green LED is lit (flashing), it indicates that there is activity on the network or external storage
device.
Location LED
The system administrator can remotely turn on this blue LED to aid in visually locating the blade server.
When this LED is lit, the location LED on the BladeCenter chassis is also lit. The location LED can be
turned on and off through the advanced management module web interface or through IBM Systems
Director. For more information about the advanced management module web interface, see the IBM
BladeCenter Advanced Management Module: User's Guide. For more information about IBM Systems
Director, see the documentation, which is available at http://publib.boulder.ibm.com/ infocenter/
director/v6r2x/index.jsp.
Information LED
When this amber LED is lit, it indicates that an Automatic BIOS recovery (ABR) has occurred. The blade
server starts up using the backup UEFI image. See the Problem Determination and Service Guide
The information LED can be turned off through the advanced management module CLI, SNMP, or web
interfaces or through IBM® Systems Director. For more information about the advanced management
module web interface, see the IBM BladeCenter Advanced Management Module: User's Guide. For
more information about IBM Systems Director, see the documentation, which is available at http://
publib.boulder.ibm.com/ infocenter/director/v6r2x/index.jsp.
Fault LED
When this amber LED is lit, it indicates that a system error has occurred in the blade server. In addition,
the fault LED on the chassis system LED panel is lit. See the Problem Determination and Service Guide
The fault LED turns off only after the error is corrected.
Note: When the fault LED turns off, you should also clear the IMM event log. Use the Setup utility to
clear the IMM event log.
IBM MAX5 LEDs
When there is a fault on the IBM MAX5 expansion blade, the front bezel of the IBM MAX5 expansion blade
will appear to have an orange glow. You can press the light path button on the system board of the IBM
MAX5 expansion blade to determine which LEDs are lit.
Note: If there is an orange glow, it will be referred to as MEU (Memory Expansion Unit) Fault in the system
event log.
The following LEDs are available on the IBM MAX5 expansion blade light path diagnostic panel:
See Light Path Below (LP1)
This amber LED indicates that there is a problem with the BladeCenter HX5 to which the IBM MAX5
expansion blade was attached. If this LED is lit, complete the following steps:
1. Remove the IBM MAX5 expansion blade (see "Removing an IBM MAX5" on page 29).
