BladeCenter T and BladeCenter HT alarm management

Select LEDs to view the state of the BladeCenter T or BladeCenter HT system-status page and blade server control panel LEDs. You also can use this choice to turn on, turn off, or flash the location LED on the BladeCenter unit and the blade servers, and control how the LEDs respond to alarms.

The following information is displayed:

• Media Tray and Rear Panel LEDs: Controls and displays the state of the following LEDs on the BladeCenter T or BladeCenter HT system LED panel:
  • Critical Alarm (CRT LED)
  • Major Alarm (MJR LED)
  • Minor Alarm (MNR LED)
  • Location

  You can change the state of the location LED and select the active LED color (red or amber) for the critical and major alarm LEDs. This color selection is applied to the LEDs on the front and rear of the BladeCenter T or BladeCenter HT unit and to the LED indications that are shown on this page. You can also specify whether the management module lights LEDs for all alarm levels that occur (critical, major, or minor) or whether it lights only the LED that corresponds to the most severe alarm level that occurs. Amber is the default color of the critical and major alarm LEDs. The management module is also set to light the LEDs for all alarm levels that occur (critical, major, or minor), by default.

• Set Alarm Panel LEDs: You can control the status of the LEDs on the front and rear of the BladeCenter T or BladeCenter HT unit by using the alarms database of the management module. Alarms can be added to the alarms database to provide user-defined control. To add an alarm, you must select the alarm severity that specifies which LED the alarm controls and enter a non-blank alarm description; then, click Set. After an alarm is added to the database, you can manage the alarm and its associated LED from the System Status page by using the ACK and CLEAR push buttons (see System Status for information).
• Blade LEDs: The state of the following LEDs on the blade server control panel. You can change the state of the information and location LEDs.
  • Power
  • Error
  • Information
  • Keyboard, video, and monitor select
  • Media (optical drive and USB port) select
  • Location
• I/O-Module LEDs: The state of the LEDs on some I/O modules.
• Hardware Component LEDs: The state of the LEDs on some BladeCenter hardware components. Some components include a FRU ready for removal LED; the status of this LED is shown in the Safe to Remove column. On BladeCenter HT chassis, you can plug compact flash cards into the media trays to extend the capacity of local storage on the advanced management module. In this way, you can upload larger ISO/image files by using the remote disk feature. To ensure the filesystem integrity on compact flash cards, make the media tray ready for removal by first clicking the Safely Remove button. After the Safe to Remove message becomes Yes, you can remove the media tray. If you change your mind after the media tray becomes Safe to Remove, then you can click the Re-Enable push button to remount the file system on the compact flash cards.
