Introduction

Overview

This guide demonstrates how to replace the BIOS ROM chip in an Open Compute V2 server. == Acronyms and Terms == * BIOS - Basic Input/Output System * SATA - Serial ATA * ROM - Read-Only Memory * SFP+ - Enhanced Small Form-factor Pluggable; a type of data communications transceiver.

  1. The server can be powered off remotely or on the hardware itself.

    • The server can be powered off remotely or on the hardware itself.

    • Remote Power Down: Login to the server to power it off.

    • shutdown -h now;exit

    • Hardware Power Down: Press and hold the power switch for at least three seconds, as annotated.

    Edit

  2. Press the button on the server sled release lever and pull the lever. This unlocks the sled from the chassis. This unlocks the sled from the chassis.

    • Press the button on the server sled release lever and pull the lever.

    • This unlocks the sled from the chassis.

    Edit

  3. Disconnect the 10G SFP+ cable from the network interface controller. Disconnect the SATA / power cables connected to the boot hard disk drive. Node 1 (right-most sled) boot drive is the top drive in the chassis. Node 0 (left-most sled) boot drive is the bottom drive in the chassis.

    • Disconnect the 10G SFP+ cable from the network interface controller.

    • Disconnect the SATA / power cables connected to the boot hard disk drive.

    • Node 1 (right-most sled) boot drive is the top drive in the chassis. Node 0 (left-most sled) boot drive is the bottom drive in the chassis.

    • Disconnecting the SATA / power cable can be performed on either the motherboard or HDD end of server node 1 . However, the SATA / power cable must be disconnected from the motherboard end on node 0.

    Edit

  4. Pull the server sled from the chassis.

    • Pull the server sled from the chassis.

    Edit

  5. Place the server sled on a work surface.

    • Place the server sled on a work surface.

    Edit

  6. Locate and identify the BIOS ROM chip on the system motherboard. The BIOS ROM chip is located just below the CPU 0 heatsink. BIOS ROM is printed next on the BIOS ROM chip socket on the motherboard.

    • Locate and identify the BIOS ROM chip on the system motherboard.

    • The BIOS ROM chip is located just below the CPU 0 heatsink. BIOS ROM is printed next on the BIOS ROM chip socket on the motherboard.

    • Lift the BIOS ROM chip cover.

    Edit

  7. Note the orientation of the BIOS ROM chip.

    • Note the orientation of the BIOS ROM chip.

    • Important: A small orientation mark is printed near PIN 1 on the BIOS ROM chip. Note this orientation as the new BIOS chip will need to be installed in the same way.

    • You may also use the motherboard's silkscreen to determine the BIOS ROM chip's PIN 1 position.

    Edit

  8. Use tweezers (or a similar tool) to extract the BIOS chip from the motherboard.

    • Use tweezers (or a similar tool) to extract the BIOS chip from the motherboard.

    Edit

  9. Obtain a new BIOS ROM chip. Place the BIOS ROM chip in the BIOS ROM chip socket. Make sure the BIOS chip has properly seated in the BIOS socket. The BIOS chip should be firmly seated, and not loose.

    • Obtain a new BIOS ROM chip.

    • Place the BIOS ROM chip in the BIOS ROM chip socket.

    • Make sure the BIOS chip has properly seated in the BIOS socket. The BIOS chip should be firmly seated, and not loose.

    • Important: Ensure the orientation of the new BIOS chip reflects the old orientation (based on the circle polarity indicator).

    • Close the BIOS ROM chip cover.

    Edit

  10. Slide the server back into the rack. Connect the peripheral cables (SATA / power and networking) that were previously disconnected.

    • Slide the server back into the rack.

    • Connect the peripheral cables (SATA / power and networking) that were previously disconnected.

    Edit

  11. Power on the server.

    • Power on the server.
