ADLINK cPCI-6530 Core i7 Blade Computer Deployment Guide

Intel Rapid Storage Technology - Enable AHCI/RAID mode to optimize SATA performance.

USB 3.0 driver - Ensure that the front USB 3.0 port operates at SuperSpeed.

Realtek HD Audio - High fidelity audio is exported through RTM.

Intel MEI driver - supports AMT remote management.

For Linux (such as RHEL/Edora) and VxWorks, BSP can be downloaded from the ADLINK official website. VxWorks users need to pay special attention to SMP configuration (i7 has four cores and eight threads). If using Wind River Workbench, SMP support must be enabled in the BSP.

Advanced BIOS tuning

CPCI-6530 adopts AMI EFI BIOS, and Chapter 8 of the manual provides detailed settings. The following are several things that must be paid attention to during deployment:

7.1 CPU Configuration (Section 8.3.3)

Hyper Reading: It is recommended to enable it on Windows/Linux and disable it on older real-time systems (such as VxWorks 5.5) to avoid logical core scheduling overhead.

Turbo Mode: High performance applications can be enabled, but it will increase instantaneous power consumption and heat generation; If the cooling conditions of the chassis are limited, it is recommended to disable Turbo to stabilize TDP.

Intel VT-x/VT-d: Virtualization environment needs to be enabled; If it is only used for real-time bare metal applications, it can be disabled to reduce the attack surface.

7.2 SATA Configuration (Section 8.3.4)

SATA Mode: AHCI mode is recommended (supporting NCQ and hot swappable), and IDE mode is optional for compatibility with older operating systems.

Hot Plug: If using RTM external pluggable hard drive, the corresponding port needs to be set to Enabled.

7.3 Startup Settings (Section 8.5)

Quiet Boot: It is recommended to disable during the debugging phase to view POST self-test information; Logo display can be enabled during the mass production stage.

Fast Boot: Skip partial initialization after enabling, which can shorten startup time, but may affect PMC/XMC enumeration. If the extension module does not recognize it, try disabling it.

IPMI Remote Management and Fault Diagnosis

CPCI-6530 integrates IPMI (Intelligent Platform Management Interface) v2.0 and achieves system health monitoring through onboard BMR-AVR-cPCI Management Controller (IPMC). Chapter 9 of the manual provides a complete summary of IPMI commands and a list of sensors.

8.1 Communication Configuration

IPMB address: automatically assigned based on CompactPCI Geographic Address (GA), Table 9-1 shows the mapping relationship (e.g. GA=1 corresponds to IPMB address 0xB0). If the chassis has multiple system blades, ensure that the addresses do not conflict.

Serial port connection: The host needs to use COM6 (IO=0x2F0, IRQ=7), baud rate 9600, 8 data bits, no checksum, 1 stop bit, and no flow control.

8.2 Key Sensors

Table 9-5 in the manual lists six core sensors:

01h - BMC Watchdog: configurable timeout actions (hard reset, power off, power on cycle).

02h~04h -3.3V/5V/12V: Power supply voltage monitoring. If it exceeds ± 5% tolerance, the front panel hot swappable LED will flash slowly as a prompt (Table 4-1).

05h - CPU temperature: Normally around 40 ℃, it may rise to 70-85 ℃ at full load.

06h - System temperature: The internal ambient temperature of the chassis is normally between 25-40 ℃.

8.3 Typical operation and maintenance scenarios

Remote Reset: Use the IPMI command Cold Reset (NetFn=App, CMD=02h) to remotely reset the IPMC without physical contact.

Event Log: Using Platform Event Message (NetFn=SE, CMD=02h), events can be written to the System Event Log (SEL) for post fault analysis.

Watchdog (WDT) configuration and high availability

Section 7.1 of the manual provides a detailed description of the watchdog timer based on ITE Super I/O IT8783, with a timeout range of 1-15300 seconds. Deployment suggestion:

Application feeding dog: Refer to the provided C code example to periodically write reset values to I/O ports 0x2E/0x4E. If the application process crashes or deadlocks, WDT will automatically reset the hardware after timeout, improving system availability.

Enable/Disable in BIOS: If there are frequent breakpoints during debugging, WDT can be temporarily disabled in BIOS to avoid accidental restarts.

Practical tips for on-site troubleshooting

10.1 No display during startup

If using cPCI-6530 (non-V version), the front panel does not have DVI and BIOS needs to be accessed through RTM or serial console (COM redirection, see section 8.3.10).

Check the "Primary IGFX Boot Display" setting in BIOS (Section 8.4.2): The default is VBIOS automatic detection. If there is no output when connected to a DVI monitor, try forcing it to CRT/DVI.

10.2 PMC/XMC module not recognized

Check if the SW-PMC1 switch is forced to PCI mode (Pin3 ON) - many older PMC modules do not support PCI-X 133MHz.

Confirm module power supply: If the module requires+5V or+3.3V auxiliary power supply (PMC connector JN1/5 Pin1 is+12V, but some modules require+5V backup), check if the backplane provides it.

10.3 System unable to hot plug

Confirm that the system supports the PICMG 2.1 hot plug specification and that the operating system driver has been installed.

Hot swappable LED status indicator (Table 4-1): Flash (0.1s on, 0.9s off) indicates readiness to shut down; Constant light indicates that it can be pulled out; Slow flashing (2s on, 1s off) indicates that a certain voltage exceeds the ± 5% tolerance and the power supply needs to be checked.
