Removing the 8248-L4T, 8408-E8D, or 9109-RMD TPMD card

Use this procedure to remove the thermal power management device (TPMD) card.

For information about using the Hardware Management Console (HMC) to remove the TPMD card, see Removing a part using the Hardware Management Console

To remove the TPMD card from a system that is not managed by an HMC, complete the following steps:

  1. Complete the prerequisite tasks. For instructions, see Before you begin.
  2. Use the service indicator light-emitting diodes (LEDs) to help identify the part. For instructions, see Identifying a part.
  3. Stop the system, as described in Stopping a system or logical partition.
  4. Disconnect all power cords from the unit you are servicing.

  5. If you have a rack-mounted system, place it in the service position. For instructions, see Placing a rack-mounted model 8248-L4T, 8408-E8D, or 9109-RMD in the service position.
  6. Attach the wrist strap.
    Attention:
    • Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge (ESD) from damaging your hardware.
    • When using a wrist strap, follow all electrical safety procedures. A wrist strap is for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
    • If you do not have a wrist strap, just before removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds.
  7. Press the push button on the planar to turn on the TPMD LEDs.
