Replacing the PERC H750 RAID Controller

Last Updated : Jan 16, 2023 |

Before you begin

Ensure that you locate the following components on the system motherboard. Refer to the label located on the inside of the server lid.

  • PERC H750 Controller

  • PERC H750 Controller cable connector (SAS Cables)

Caution:

Always practice safe electrostatic discharge procedures. For more information, see Electrostatic discharge safety.

Warning:

These steps are service impacting, conduct this activity during a customer approved maintenance window.

Procedure

  1. Power down the server according to Avaya's application instructions and disconnect the system from the electrical outlet by removing both power cords.
  2. Open the server lid and locate the PERC H750 card located in right rear (as viewed from the front) of the server installed in PCIe slot 1. See Figure : 2 for H750 location.
  3. Refer to Figure : 1 below. Disconnect the storage controller cable from the PERC H750 card connector.
  4. Lift the PCIe Expansion riser out of the server (Figure : 2; Figure : 3) using the blue touch points.
  5. Turn over the Expansion Riser, open the blue card retainers and remove the PERC H750 card from the PCIe connector and place to the side. Refer to Figure : 4.
  6. Insert new/replacement PERC H750 card into the riser’s PCIe connector. Ensure H750 PCIe connector is fully inserted into the Expansion riser’s PCIe connector socket using connector keying and PCIe faceplate for alignment. Refer to Figure : 5.
  7. After the new H750 has been fully seated into the riser, turn the riser over and insert it into the server motherboard connector. Refer to Figure : 6.
  8. Connect the storage controller cable to the newly inserted H750’s SAS connector. Place the server lid on, reconnect cables if applicable, and power up the server.
  9. If the Raid battery is not installed in replacement PERC card remove the battery from the failed PERC card and insert in the new replacement PERC card. See Chapter 10 Raid Battery for additional information if needed.
