Handling Precautions

WARNING: This system has internal components which may be damaged by electrostatic discharge.

To protect internal components from electrostatic damage, be sure to observe the following precautions when

handling or storing the system:

• The MBT8301 has a net chassis weight of approximately 41.0lbs. (18.59kg). This base chassis weight

includes the chassis, an MBC8240 modular blade card, an TMI8241 mid-plane inteface board, and a rear-

mounted AC power supply. Use proper lifting techniques when moving and installing the system.

• When removing or installing boards and sub-components, keep these components in their static-shielded

bag and/or packaging until you are ready to for component installation.

• Handle the sub-components by their edges.

• Do not touch any sub-component I/O connector pins. Do not apply pressure or attach labels to the board-

level sub-components.

• Use a grounded wrist strap at your system or ground yourself frequently by touching the metal chassis of

the system before handling any sub-components.

• Ensure the systems external power source has a solid connection to an earth ground.

• Use antistatic padding on all work surfaces when installing or removing sub-components.

• Avoid static-inducing carpeted areas.

MBT8301 Technical Reference

Before You Begin

Introduction

It is important to be aware of the information listed below before installing your Trenton modular blade

server. System performance may be affected by incorrect usage of these features.

External Power Source – Redundant 900w Power Supply Version

Incoming AC power must be supplied to both of the power supply receptacles located at the rear of the chassis.

These dual AC power connections ensure that the active system power supply; as well as the stand-by/fail-over

supply, is each connected to a power source with a solid earth ground, and each supply must have an incoming

power source of: 100-127/200-240VAC, 10A/5A at 50 to 60Hz.

Chassis Airflow

When installing the chassis, ensure that a minimum free air space is available around the system. The installation

should have a minimum of 4-6 inches (101-152mm) behind the chassis and 7-8 inches

(178-203mm) in front of the chassis. Any front cabinet doors or access aisles must accommodate a MBT8301 front

chassis clearance of at least 7.0” (178mm) in order to provide proper clearance for the fan FRU replacement.

Ideally, a chassis clearance of 0.5-1.5 inches (13-38mm) above the system is desirable

CHASSIS PLACEMENT

The MBT8301 system is designed with ruggedness in mind, however, precautions should be observed to ensure safe

and reliable performance. Place the chassis on a flat, stable surface capable of supporting both the system weight

and any anticipated peripherals. Installation area should be secure and free from danger of liquid or airborne

contaminants that could damage internal components as well as supporting all airflow requirements.

Chapter 1 | Modular Blade System Overview

Description

The Trenton MBT8301-xxx is a CE-compliant and UL recognized, modular blade server tower optimized for

system performance, longevity, and easy field support. The tower-style enclosure of the MBT8301 is

designed for both server room and rugged field deployment locations that require outstanding system

performance in a form factor comparable to traditional mid tower chassis designs.

At the heart of the MBT8301 is Trenton’s U.S. designed and Made in America MBC8240 modular blade card

or SBC. The MBC8240 SBC supports a long-life Intel® processor that delivers superior multi-core

processing performance with the thermal characteristics necessary for reliable and long-term 1U rackmount

server operation in a wide variety of application environments. The MBT8301 chassis supports two, 2.5”

front-access/hot-swap HDD carriers, one media drive bay, and an AC power supply. These components

maximize power delivery and cooling to ensure long-life system reliability with minimal Mean-Time-To-

Repair (MTTR) times.

The MBT8301 server solution supports seven Ethernet interfaces with one port dedicated to remote system

management, up to two HDD or SDD storage drives, an optical media drive, and a hot swappable power

supply. The MBT8301 also has the ability to support an off-the-shelf PCI Express plug-in option card. Some

typical MBT8301 applications include data servers, industrial automation machinery, and weapon control

systems.

DDR3 Memory & CARD Memory Population Rules

Trenton recommends ECC registered DDR3-1600 memory modules for use on the

MBT8301/MBC8240. Unbuffered ECC DDR3 DIMMs are also supported, however, you cannot mix the

ECC registered and unbuffered ECC memory types on the same board.

Each processor on a MBC8240 supports 2 channels of memory. The maximum possible memory interface

speed obtained depends on the specific Intel

processor used on the board and other board configuration

options.

Trenton recommends populating the memory sockets

starting with the DIMM closest to the processor socket.

The DIMMs are arranged in an alternating channel pattern.

Moving away from the processor they are: 0A, 0B, 1A, 1B.

For optimal performance, populate each channel fully before

populating the other channel, i.e., populate Channel A’s 0 and

1 slots before populating Channel B’s 0 and 1 slots.

The memory DIMMs on the SHB connect directly to the CPU

and at least one memory module must be installed on the

board for operation.

Universal Serial Bus (USB)

The MBT8301 supports nine (9) USB 2.0 ports. Two are located on the front panel adjacent to the fan fault

indicator lights. One (1) is located on the SBC and six (6) are located on the rear I/O area of the SHB.

Video Interface

The SHB features a Graphics Processing Unit (GPU) onboard the ASPEED AST2400 with 8MB of video

memory. The GPU is driven by a x1 PCIe link from the SHB’s Intel

C226 PCH. This combination of

features enables the SHB’s video port; located on the board’s I/O plate, to support pixel resolutions up to

1920 x 1200 (WUXGA).

PCI Express Interface

A full-height, PCI Express 3.0 x16 mechanical/x8 electrical interface is supported by the Intel

Xeon

processor in the MBT8301 via the BRC8244 riser card. PCI Express automatic link negotiation and

bifurcation are implemented and previous PCIe link speeds, Gen 1.1 and 2.0, are also supported. PCI

Express’ link scalability allows for cards with fewer electrical lanes to function in the server’s card slot

supported by the MBC8240 modular blade card and BRC8244 riser card combination. The MBC8240’s PCIe

link will automatically negotiate between the processor’s root link and the plug-in target card for the fastest

possible link speed.

A Word about PCI Express 3.0 Interfaces

PCIe 3.0 doubles the PCIe 2.0 per lane interface speed from 500MB/s (5GT/s) to 1GB/s (8 GT/s) via speed

changes and protocol enhancements. As with all previous versions of the PCI Express specification, the PCIe

3.0 interface is backwards compatible and will run Gen3, Gen2 and Gen1.1 I/O cards on the same interface

link. Running a PCIe 3.0 target device such as a Gen3 I/O card at the actual PCIe 3.0 interface speed of

1GB/s requires that the PCIe 3.0 link from the root complex (i.e. the processor on the MBC8240) to the

target card be tuned and optimized to meet the speed requirements of PCI Express 3.0. If these tuning

conditions are slightly off or not fully optimized, then the interface will operate at a slower interface

speed. Contact Trenton for more details regarding the specifics of your particular PCIe 3.0 implementation.

Ethernet Interfaces

The MBT8301 has six (6) general-purpose 10/100/1000Base-T Ethernet interfaces (Lnk 1-6) available on the

rear I/O plate of the Modular Blade Card. An additional 10/100/1000Base-T Ethernet interface (Lnk 0) is

dedicated to Trenton’s IPMI implementation, Trenton Smart System Management (SSM). Trenton SSM

allows for remote maintenance and monitoring of health and stability of your Trenton MBT8301.

SATA/600

There are six (6) Serial ATA (SATA) interfaces available on the MBT8301. Three SATA ports are on the

SHB. Three SATA/600 interfaces are routed to the edge connector of the SHB for use on a SATA-equipped

Modular Blade System Midplane Interface Card, such as the MPI8241. All of the SATA interfaces are

driven with a built-in SATA controller from the Intel

C226 Platform Controller Hub (PCH). The board’s

SATA ports can support six independent SATA storage devices such as hard disks and CD/DVD-RW devices

at data transfer rates up to 600MB per second on each port.

The SATA controller has three BIOS selectable modes of operation located under the Advanced/SATA

Configuration menu with a legacy (i.e. IDE) mode using I/O space, an AHCI mode using memory space and

a RAID mode. Additionally, the SATA implementation supports Hot Plugging/Swapping to reduce MTTR.

Chapter 4 | Trenton Smart System Management (Trenton SSM)

The Smart System Management (SSM) software embedded in the MBC8240 is accessible via the dedicated

management Ethernet LAN (Lnk 0). This dedicated interface provides full Ethernet 10/100/1000Base-T bandwidth

and, optionally, isolation of these functions to a specific LAN. Trenton’s SSM is built upon the industry standard

Intelligent Platform Management Interface (IPMI) and its related sub-components including:

• Intelligent Platform Management Bus (IPMB)

• IPMI Platform Management FRU Information Storage Definition

• Intelligent Chassis Management Bus (ICMB)

Trenton SSM’s implementation of IPMI provides seamless and efficient out-of-band management and control

capability from any compatible device worldwide, regardless of the power-on state and is operating system-agnostic.

A short list of Trenton SSM application software functionality includes:

• Fan speed monitoring

• Fan condition & status

• Alarm monitoring

• FRU management

• Voltage monitoring

• SBC present

• Remote messaging (i.e. call home)

• Polling for processor & memory health

The “intelligence” behind Trenton SSM is the Baseboard Management Controller (BMC). It is driven by firmware

that is capable of being upgraded locally or remotely. Management can be done inside a Linux or Windows

operating system environment locally or remotely, via software issued under license from American Megatrends

Inc. (AMI) for AMI’s Yet Another Firmware Upgrade Flash (YAFUFlash) tool. Additional information about

YAFUFlash and its implementation in the MBT8301 is available in the MBC8240 BIOS and Trenton Smart System

Management Technical Reference Document.

Chapter 5 | BIOS Messages

Introduction

A status code is a data value used to indicate progress during the boot phase. These codes are outputted to I/O port

80h on the MBC8240 card. Aptio 4.x core outputs checkpoints throughout the boot process to indicate the task the

system is currently executing. Status codes are very useful in aiding software developers or technicians in

debugging problems that occur during the pre-boot process.

Aptio Boot Flow

While performing the functions of the traditional BIOS, Aptio 4.x core follows the firmware model described by the

Intel Platform Innovation Framework for EFI (“the Framework”). The Framework refers the following “boot

phases”, which may apply to various status code descriptions:

 Security (SEC) – initial low-level initialization

 Pre-EFI Initialization (PEI) – memory initialization

 Driver Execution Environment (DXE) – main hardware initialization

 Boot Device Selection (BDS) – system setup, pre-OS user interface & selecting a bootable device

(CD/DVD, HDD, USB, Network, Shell, …)

Analogous to “bootblock” functionality of legacy BIOS

Analogous to “POST” functionality in legacy BIOS

BIOS Beep Codes

The Pre-EFI Initialization (PEI) and Driver Execution Environment (DXE) phases of the Aptio BIOS use audible

beeps to indicate error codes. The number of beeps indicates specific error conditions.
