Adapter Security

The adapter hardware secure boot security feature protects your system from malicious activity.
Hardware secure boot permits only authenticated firmware to execute on the adapter. The adapter boots from an internal boot ROM, which establishes the initial root of trust (RoT). Hardware secure boot authenticates and builds a chain of trust (CoT) with succeeding firmware images by using the RoT, meaning only authorized firmware executes on the adapter.

Figure 1: Authenticated Firmware Example

Hardware secure boot requires that each image be signed with a valid digital signature; otherwise, the image is considered invalid and does not execute. The adapter ships with a valid signed firmware image. All Broadcom-supplied firmware includes a valid digital signature; therefore, the hardware secure boot process is transparent unless the adapter encounters a counterfeit image. If the adapter downloads a counterfeit image, the image authentication fails and the download utility, such as StorCLI2, displays the appropriate failure messages. Contact Broadcom Technical Support for assistance.

Adapter Installation Instructions

Use the following steps to install the adapter:

1. Unpack your adapter.
   Unpack and remove the adapter. Inspect the adapter for damage. If it appears damaged, contact Broadcom Technical Support.
   ATTENTION
   To avoid the risk of data loss, back up your data before you change your system configuration.

2. Turn off the power to the system.
   Turn off the power to the computer and disconnect the AC power cord. Remove the computer cover. Refer to the system documentation for instructions. Before you install the adapter, make sure that the computer is disconnected from the power and from any networks.
   CAUTION
   Disconnect the computer from the power supply and from any networks to which you will install the adapter, or you risk damaging the system or experiencing electrical shock.

3. Review the adapter connectors. See MegaRAID 9540-2M2 Boot Adapter – Connector and LED Designations for descriptions of the adapters that show their connectors.

4. Check the mounting bracket on the adapter.
   If required for your system, replace the full-profile mounting bracket that ships on the adapter with the low-profile bracket supplied. Complete the following steps to attach the low-profile bracket:

   • Using a No. 1 Phillips screwdriver that is ESD safe, remove the two Phillips screws that connect the full-profile bracket to the board. Unscrew the two screws located at the top and bottom edges of the board. Avoid touching any board components with the screwdriver or the bracket.
   • Remove the full-profile bracket. Do not damage the adapter.
   • Place the adapter on top of the low-profile bracket. Position the bracket so that the screw holes in the tabs align with the openings in the board.
   • Using a No. 1 Phillips torque screwdriver that is ESD safe, set to a maximum torque of 4.8 ± 0.5 inch-pounds. Replace the two Phillips screws removed in Step a.
     ATTENTION
     Exceeding this torque specification can damage the board, connectors, or screws, and can void the warranty on the board.
     ATTENTION
     Damage caused to the board as a result of changing the bracket can void the warranty on the board. Adapters returned without a bracket mounted on the board will be sent back without return merchandise authorization (RMA) processing.

5. Install the stand-offs. Two black plastic stand-offs with attached fasteners are provided with the adapter. Insert the stand-offs in the appropriate holes for the M.2 drive length and press to snap into place.

6. Install the M.2 drives. Install the M.2 SSDs into the adapter’s connectors. Secure the SSDs into place by pushing the fastener through the notch on the M.2 drive into the stand-off. The adapter supports the following M.2 drive lengths:

   • 110 mm
   • 80 mm
   • 60 mm
   • 42 mm
   • 30 mm

7. Insert the adapter into an available PCIe slot. Select a PCIe slot and align the adapter’s PCIe bus connector to the slot, as shown in the following figure. Press down gently, but firmly, to make sure that the adapter is seated correctly in the slot. Secure the bracket to the computer chassis with the bracket screw.
   NOTE
   Adapters with a x8 host interface can operate in x8 or x16 slots. However, some x16 PCIe slots support only PCIe graphics cards; an adapter installed in one of these slots will not function. Refer to the guide for your motherboard for information about the PCIe slots.
   Figure 2: Installing an Adapter in a PCIe Slot
   

8. Provide the required airflow for the installed adapter. See MegaRAID 9540-2M2 Boot Adapter Technical Specifications to find the adapter’s cooling requirements.

9. Turn on the power to the system. Reinstall the computer cover and reconnect the AC power cords. Turn on power to the host computer.
   During boot, a BIOS message appears. The firmware takes several seconds to initialize. The configuration utility prompt times out after several seconds. The second portion of the BIOS message shows the adapter controller number, and firmware version. The numbering of the adapters follows the PCIe slot scanning order used by the host motherboard.

10. Choose the correct storage profile. Refer to the 12Gb/s MegaRAID Tri-Mode Software User Guide and LSI® Storage Authority Software User Guide for details about setting up your adapter.

11. Install the operating system driver. The adapters can operate under various operating systems. To operate under these operating systems, you must install the software drivers.

MegaRAID 9540-2M2 Boot Adapter Technical Specifications

The operating (thermal and atmospheric) conditions for the adapter are as follows:

• Relative humidity range (non-condensing): 5% to 90%
• Temperature range: 0°C to +55°C

The minimum airflow required depends on the installed M.2 SSDs. The minimal airflow without any M.2 drives is 150 LFPM measured at 55°C (ambient). When attaching M.2 drives, you must supply enough airflow to cool the M.2 drives and to keep the SAS3808 IOC processor’s junction temperature at 105°C or less. The M.2 drives might require heat sinks. M.2 drive heat sinks are available from third-party suppliers.
The non-operating (such as storage and transit) conditions for the adapter are as follows:

• Relative humidity range (non-condensing): 5% to 95%
• Temperature range: –40°C to +70°C

Power Supply Requirements
All power, included that used to power the onboard M.2 drives, is supplied to the adapter through the PCIe 3.3V rail (3.3V± 9%) and the 12V rail (12V ± 8%). Onboard switching regulator circuitry operates from the 3.3V rail and the 12V rail to provide the necessary voltages. Each M.2 drive may use a maximum of 11.55W.
The M.2 drives are powered from the 12V rail with the 1.5V and 1.8V SAS3808 supplies. Using the 12V rail, the adapter can support the maximum power requirements of the M.2 drives. The SAS3808 core rail is powered from the 3.3V rail which requires approximately 6W. This means, depending on the drives being used, the adapter might draw more than 25W total (the limit of some x8 slots). However, many systems combine the 12V and 3.3V rails to supply up to 35W (25W from the 12V rail and 10W from the 3.3V rail). The total power consumed depends on which M.2 SSDs drives are used. You must complete a power analysis based on the drive selection for your system.
The following values represent typical power using two 500 GB x4 NVMe PCIe 16GT/s drives:

• PCIe 3.3V: 6W
• PCIe +12V: 11.5W
• Total power: 17.5W

Typical power is measured with maximum I/O traffic, typical silicon process material, and nominal voltages operating the card at an ambient temperature of 45°C with required airflow.
