Product Overview 1
Chapter 1: Product Overview
This chapter describes the TelumTM GE-QT 4-Port Gigabit Ethernet Advance Mezzanine Card
(AdvancedMC® or AMC) Network module. The Telum GE-QT is a 4-port Ethernet AMC network
module also known as a network interface card (NIC). The Telum GE-QT 4-Port Gigabit Ethernet
AdvancedMC NIC (hereafter referred to as the Telum GE-QT) provides high bandwidth and high
port density in a single-wide, full-height module that complies with the Peripheral Component
Interface (PCI) Industrial Computer Manufacturers Group (PICMG®) AMC specifications. The
Telum GE-QT was designed for optimized implementation in the following chassis/shelves:
•ATCA-compliant
•SBS’ AMC chassis, PCIE-AMC-7S
•MicroTCA-compliant1
•Proprietary shelves designed to be AdvancedMC module-compliant
Product Overview
The Telum GE-QT contains a x4 PCI Express bus that complies with the AMC.1 specification. The
Telum GE-QT provides a fast, standards-based, cost-effective reliable data pipe with speeds up to
one billion bits per second. To reduce host CPU utilization, the Ethernet controller on the Telum
GE-QT supports Transmission Control Protocol (TCP) segmentation and checksum off loading.
The Telum GE-QT provides four external RJ-45 ports for connectivity and can also be used on an
AdvancedTCAchassis.Allports are accessible by software. The Telum GE-QT complies with IEEE
802.3a specification to support 10BaseT, 100BaseTX and 1000BaseT modes over Category-5 (or
better) twisted pair (4-wire pairs) cable.
The Telum GE-QT provides media access control (MAC) and physical layers of the Open Systems
Interconnection (OSI) protocol mode. It complements upper layer protocols such as TCP and
Internet Protocol (IP), which allows reliable communications services between applications.

industry standard to provide an “always available” module that supports:
•Monitoring of hardware information, such as voltages and temperature
•Monitoring of hardware sensors and alarm generation (alerts)
•Field Replaceable Unit (FRU) hot-swap functions
A special Module Management Controller (MMC) provides IPMI module management and control.
In addition, the Telum GE-QT hardware meets the intra-building (short haul) transient immunity
requirements of Bellcore GR-1089 for telecommunication applications.
For more information on the hardware components, see “Chapter 2: Hardware Description.”
Firmware Overview

Gigabit Ethernet Controller
Each of the two Dual Gigabit Ethernet (GbE) Controllers contains two fully-integrated, MAC and
physical-layer circuits to provide two standard IEEE 802.3 Ethernet interfaces.The Dual GbE
Controllers support 10BaseT, 100BaseT,X and 1000BaseT operational modes, which comply with
IEEE 802.3 (802.3u, 802.3ab) specifications. Each port features auto-negotiations and automatic
MDI/MDIX switchover on RJ-45 ports to enable greater compatibility with existing devices and
infrastructures. Both full-duplex and half-duplex modes are supported in 10BaseT and 100BaseTX
modes. The 1000BaseT mode supports only full-duplex operations.
PCI Express Switch
The PCI Express Switch is used to aggregate the two Ethernet controllers into a x4 PCI Express
that goes to the AMC connector. Each Ethernet Controller is connected by x4 PCI Express to the
PCI Express Switch.
NOTE
One Ethernet Controller consists of two ports.
The PCI Express Switch provides four lanes of PCIe to the PICMG fat pipe region (Lanes 4, 5, 6,
and 7).
IPMI Controller
The Telum GE-QT module provides an Intelligent Platform Management interface (IPMI) to
communicate with the AdvancedTCA Shelf Manager inside the shelf. The Telum GE-QT complies
with AMC.0 industry standard to provide an “always available “module that supports the following
features:
•Monitoring of hardware information, such as voltage and temperature
•Monitoring of hardware sensors and alarm generation (alerts)
•Field Replaceable Unit (FRU) hot swap functions
The Telum GE-QT contains a special Module Management Controller (MMC) to provide IPMI
module management and control.
Module Management Controller
Each Telum GE-QT contains an MMC. The MMC is an IPMI microcontroller that manages and
controls IPMI operations. The Shelf Manager and the Telum GE-QT communicate (as shown in
Figure 3) through a limited set of IPMI commands on the local IPMI bus (IPMB-L). The MMC
provides a variety of functions including the following:
•Temperature sensors
•Power reset and control
•Electronic keying (E-keying)
•Field Repeatable Unit (FRU) “hot swap” information
The MMC contains a single, centralized repository in non-volatile storage to log sensor, device
locator, and entity association records for all sensors on the Telum GE-QT.
The MMC stores Telum GE-QT FRU information and upon appropriate event, lights the front panel
blue hot swap LED when it is safe to remove the Telum GE-QT from a live chassis or shelf.

Hardware Overview 9
Figure 3. MMC Communications
Temperature and Voltage Sensors
The MMC monitors the temperature and voltage of the module and provides automatic alert and
shutdown, as well as restart and power control capabilities. The sensor data monitors the FRU by
providing records that can be read at any point in time as directed by the Shelf Manager. Events
from the sensors are sent if the sensor readings transition above or below the sensor threshold
listed in Table 2 through Table 4.

Electronic-Keying (E-Keying)
E-Keying is an AdvancedTCA management layer that performs the following:
•Inventories the Field Replaceable Units (FRUs) in the shelves of a system
•Monitors the FRUs basic health
•Manages the FRUs power, cooling and interconnect resources
The MMC contains Telum GE-QT E-keying data that the Shelf Manager uses.The PICMG IPMI
specification defines the necessary extensions to implement E-keying. The Link characteristics
define the special characteristics of the Telum GE-QT. Telum GE-QT E-keying extension include:
•The Telum GE-QT FRU header, area, and product area records (shown in Table 5) provide
module-specific information to the shelf and can be read at any time.
•TelumGE-QTFRUmulti-records (showninTable 6) arereadbytheshelfatinitialization aspart
of the E-keying process. They are used to determine compatibility with the shelf.
•The Telum GE-QT also uses two AMC link descriptors listed in Table 7. The shelf determines
which one of these descriptors represents the desired configuration for the board interface and
selects that configuration using the Set Port State IPMI command.
