Removing the IOM

About this task

Important: Consideration for removing the IOM:
  • Do not remove a faulty module unless its replacement is on-hand. All CRU modules must be in place when the system is in operation.

See CAUTION bullets regarding electrostatic discharge and anti-static protection in the ESD precautions section.

Illustrations in the IOM replacement procedures show rear panel views of the enclosure, and IOM is properly aligned for insertion into the rear panel of the enclosure.

Procedure

  1. Locate the enclosure whose ID LED (enclosure front panel – left side) is illuminated, and within the enclosure, locate the IOM in slot 0.
  2. Disconnect any cables connected to the IOM.

    Label each cable to facilitate re-connection to the replacement IOM.

  3. Unlock the IOM latch handle by turning the thumbscrew counter-clockwise as shown in detail No.1 in the figure below.

    Take care not to remove the thumbscrew from the IOM latch handle.

  4. Grasp the IOM latch handle between the thumb and index finger and pull. Revolve the handle out and downward to lever the IOM out of the enclosure as shown in details No. 2 and No. 3 in the figure below.
