Use this procedure to service the Enclosure Services Manager (ESM).

1. The ESM will be serviced non-concurrently.

   Remove power from the enclosure containing the FRU. Powering off the enclosure is accomplished through the enclosure's host server. For additional information, refer to the "Powering on and powering off" topic located in the host server's service guide.

2. Attention:

   Failure to follow the step-by-step sequence for this FRU removal and/or installation may result in FRU or system damage. Use the following precautions whenever you handle electronic components or cables. Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge from damaging your hardware. If you do not have a wrist strap, just prior to 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. Keep all electronic components in the shipping container or envelope until you are ready to install them. If you remove, then re-install an electronic component, temporarily place the component on an ESD pad or blanket, if available.

3. Remove the ESM.

   Disconnect the SAS cable from the ESM. On the left side of the ESM, press the orange release tab (A) to the right as you rotate the handle (B) upward. Using the handle, gently slide the ESM out of the enclosure, supporting the bottom while you do this.

4. Install the ESM.

   Hold the replacement ESM so that the handle (A) is fully extended. Gently slide the ESM into the bay until the ESM stops. Rotate the handle downward into the closed position until it clicks. Reconnect the SAS cable to the ESM.

5. Power on the enclosure.

   Power on the enclosure containing the FRU. Powering on the enclosure is accomplished through the enclosure's host server. For additional information, refer to the "Powering on and powering off" topic located in the host server's service guide.
