Removing and installing an enclosure RAID module assembly for a 5888 PCIe storage enclosure

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 (ESD) from damaging your hardware.
• If you do not have a wrist strap, 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.
• Keep all electronic components in the shipping container or envelope until you are ready to install them.
• If you remove and reinstall an electronic component, temporarily place the component on an ESD pad or blanket, if available.
• Do not combine the replacement of any ERM assembly with the replacement of the midplane unless there has been a power cycle of the PCIe storage enclosure with one new FRU at a time. If multiple FRUs are replaced at the same time, the serial number is not preserved.

To remove and install an ERM assembly, complete the following steps:

1. Use the location code to find the physical location of the ERM. Does the location code begin with U5888.001.sssssss, where sssssss is the serial number of the PCIe storage enclosure?

   Yes:

   Using the serial number, find the PCIe storage enclosure that has the same serial number printed on the label on the front of the enclosure. The fault indicator of the failing ERM should be on. Label the failing ERM and continue with the next step. For more information about location codes, see the service card located in the front of the enclosure or 5888 locations.

   No:

   Find the port in the system unit identified by the location code. Trace the cable to the PCIe storage enclosure to find the failing ERM. Label the failing ERM and continue with the next step. For more information about system location codes, see Part locations and location codes.

2. Power off the system that is connected to the ERM assembly to be removed. For instructions, see Powering on and powering off the system.
3. Remove the ERM assembly:
   1. Disconnect the PCIe cables from the ERM assembly and mark each cable label with its location.
      Attention: Incorrect cable placement might result in data loss.
   2. Open the release lever (A) as shown in the following figure.
   3. Support both sides of the ERM assembly (B) while you slide it out of the enclosure.

4. Install the ERM assembly:
   1. Ensure that the release lever on the new ERM assembly is in the open position.
   2. Gently slide the ERM assembly into the enclosure until it stops.
   3. Push the release lever to the closed position.
   4. Reconnect the PCIe cables to the ERM assembly by using the location information marked on each cable in step 2a.
      Attention: Incorrect cable placement might result in data loss.
5. Power on the system that is connected to the ERM assembly. For instructions, see Powering on and powering off the system.
   Note: To prevent loss of enclosure information, do not replace both ERM assemblies at the same time. To replace the second ERM, power on the system and the partition that is connected to the ERM assembly that you replaced first. Then power off the system that is connected to the second ERM assembly.
