For instructions, see “Preparing the system to remove and replace the PCIe3x8 SAS RAID internal adapter 6 Gb” on page 8.To remove the PCIe3 x8 SAS RAID internal adapter 6 Gb, complete the following steps:1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip isconnected to an unpainted metal surface. If not, do so now.2. Remove the fan cage. For instructions, see Removing a fan cage (http://www.ibm.com/support/knowledgecenter/POWER8/p8haq/p8haq_83x_8rx_fancageremove.htm).3.

Press the latch (A) and unplug the connector of the cable from the disk drive backplane, asshown in Figure 10. Leave the other end of the cables plugged in to the P1 or P2 connector on theSAS RAID internal adapter until directed to unplug them.Notes:v If you have one SAS RAID internal adapter, the adapter is in slot P1-C14 (FC EJ0T or EL3T) and thefiller is in slot P1-C15.v If you have two SAS RAID internal adapters, one of the adapters is in P1-C14 (FC EJ0T or EL3T),and the second adapter is in P1-C15 (FC EJ0V or EL3V).AP8EG5501-1Figure 10.
