Replacing a Disk Shelf I/O Module

Caution:

Do not remove a component if you do not have an immediate replacement. The disk shelf must not be operated without all components in place, including filler panels. Refer to Disk Shelf Hardware Overview for component locations.

The following disk shelves have I/O Modules (IOMs):

  • Oracle Storage Drive Enclosure DE3-24P

  • Oracle Storage Drive Enclosure DE3-24C

  • Oracle Storage Drive Enclosure DE2-24P

  • Oracle Storage Drive Enclosure DE2-24C

  • Oracle Storage Drive Enclosure DE3-12C

The I/O Modules (IOMs), which are similar to SIM boards, are hot-swappable so you can replace them without removing power to the system.

  1. A faulted I/O Module is indicated by an amber LED. From the Maintenance BUI menu, select Hardware, click the right-arrow icon apply icon at the beginning of the appropriate disk shelf row, and then click Slot to view details, or click the locator icon locate icon to turn on the locator LED.
  2. Locate the failed I/O Module at the back of the disk shelf.
  3. Label and disconnect the I/O Module interface cables.
