# 3.6 Intelligent Platform Management Bus (IPMB) The Shelf uses an Intelligent Platform Management Bus (IPMB) for management communications among all ATCA Boards and the Shelf Managers. The reliability of the IPMB is improved by the addition of a second IPMB, with the two IPMBs referenced as IPMB-A and IPMB-B. IPMB-A and IPMB-B are routed to the ATCA Slots in a bused configuration. Figure 2: Bused IPMB ![**Title:** Bused IPMB\n\n**Labeled Blocks:**\n* **Top Row:** Six identical vertical rectangular blocks. Each block contains a large grey box labeled 'ATCA Board' and a smaller white box at the bottom labeled 'IPMC'.\n* **Bottom Row:** Two large grey square blocks. The left block is labeled 'Shelf Manager 1' and the right block is labeled 'Shelf Manager 2'.\n* **Legend:** A box containing a dashed line labeled 'IPMB-A' and a solid line labeled 'IPMB-B'.\n\n**Connections:**\n* **IPMC to Bus:** Vertical lines connect each 'IPMC' block to a horizontal bus structure running below them. These vertical lines alternate in style from left to right: Solid, Dashed, Solid, Dashed, Solid, Dashed.\n* **Bus to Shelf Managers:** Vertical lines extend downwards from the horizontal bus structure to connect to both 'Shelf Manager 1' and 'Shelf Manager 2'. Each Shelf Manager is connected via both solid and dashed lines to the bus structure.](.atca-80606pd-50-1g048-1000-10/1ae7bbc77f2a763a4ae51346a0234f2127790ee8e43bd225251c66c69cc9ce41.jpg) # 3.7 Shelf SEEPROM The SEEPROMs are located at the rear side of the backplane. The Shelf SEEPROM is a repository of the shelf-specific information, capabilities of the system and other user configurable options. The SEEPROM contains as example: • A list of which slots are connected together • How the update channels are routed • How many slots are in the system • What the maximum power is to each slot • The serial number of the Shelf • The backplane topology etc. The Shelf Managers use this information to provide functions such as electronic keying, controlling the power state of the system, etc. The Shelf Managers cache the information that is stored in the SEEPROMs so that the SEEPROM is only needed when the Shelf Managers are first inserted or when the Shelf is first turned on. The redundant SEEPROMs ensure that if one is corrupt or non-functional, the second can provide the necessary information. The Shelf Manager selects what set of information is correct and then synchronizes the two SEEPROMs from the internally cached of the SEEPROM information. # 3.8 Logic Ground The ATCA Backplane provides a mechanism to connect Logic Ground and Shelf Ground. To connect Logic Ground and Shelf Ground, the mounting screws at the positions marked by arrow must be fixed. Figure 4: Logic Ground ![GND\nGND](.atca-80606pd-50-1g048-1000-10/00e5a39bf59e9aace3ee3ed24f303e06c5946622d284dd729f566ab41389536a.jpg) ![The image features a blue square with a white lowercase letter 'i' centered inside it.](.atca-80606pd-50-1g048-1000-10/9bb410742798f8a266486954fe40e035defafa107c7120b0a760dcc25381e47d.jpg) By default, Logic Ground and Shelf Ground are isolated, the chassis is shipped without the mounting screws at the marked positions. # 4 Air Filter # 4.1 Introduction The ATCA Shelf provides a front-replaceable air filter. The filter element is an open cell polyurethane foam special coating to provide improved fire retardation and fungi resistance. The filter meets the requirements of the Telcordia Technologies Generic Requirements GR-78- CORE specification. Figure 3: Air Filter ![Technical diagram of a server rack with labeled components, showing internal structure and numbered parts.](.atca-80606pd-50-1g048-1000-10/14731a299e3440ce4f6454e544bcaf407858f32ab9cfd5c61aef6a5094373899.jpg) 1.

Before powering-up the Shelf, make sure that the Shelf Ground terminals are connected to Protective Earth (PE) of the building. The ATCA Shelf provides a Shelf ground terminal at the upper rear side. The Shelf ground terminal provides two threads (M5) with a 16.0mm spacing between thread centers to connect a two hole lug Shelf ground terminal cable. Figure 4: Shelf Ground Terminal ![M5\n16 mm](.atca-80606pd-50-1g048-1000-10/3f41a34b9a7665b1742a8c2008684795c8bfe89b3ae75ff9cd630c8035a4a678.jpg) Please note that in a typical telecom environment, the VRTN path of the -48V supply is grounded to Protective Earth (PE) of the building. # 5.1 Specification of the Shelf Ground Connection Cable Required wire size: AWG8 Required terminals: Use only two hole lug terminals. (Terminal used: PANDUIT part no. LCD8-14A-L) # 6 Fan Trays # 6.1 Introduction The 6 Slot ATCA Shelf contains two hot-swappable Fan Trays arranged in a side to side configuration for maximum air flow. The Fan Trays are locked into the Shelf by a mini compression latch with indicator. A hot-swap push button is used to provide hot-swap functionality. The Fan Trays are intelligent FRUs and plugged in at the left and right front of the Shelf. Each Fan Tray contains six 92mm fans (245m3 /h (146CFM) each). The Fan Tray is controlled via an on-board IPM controller. Figure 5: Fan Tray ![Technical diagram of a server rack with labeled components and a control panel showing switches and indicators.](.atca-80606pd-50-1g048-1000-10/89b9e31e9d8a74d9068d3e6aa15d8064925bf4551f1e43ba8a2b234b0dbf636b.jpg) 1.

Mini Compression Latch # 6.2 Fan Control Model The onboard IPM controller is located on the Fan Tray and has 2 operation modes: # 6.2.1 Shelf Manager Mode As soon as a Shelf Manager is plugged-in and becomes active, the IPM controller switches automatically into the Shelf Manager mode. The Shelf Manager performs management of the Fan Tray through the two independent bussed IPMB connections. When the Fan Tray is first inserted into the system, the fans start at full speed and then decrease to the specified speed by Shelf Manager. The circuitry on-board the Fan Tray uses a PWM signal to control the speed of all the fans. Lower speeds reduce acoustic noise and power consumption and increase the lifetime of the fans. The speed of each individual fan is monitored. If any of the fan speeds drops below the desired fan speed, a System Event Log (SEL) entry is logged by the Shelf Manager. The Shelf Manager then generates alerts and sets alarm conditions as necessary. The system is designed to run indefinitely with any single fan failure. When one fan fails, all other fans are increased to full speed. The Fan Tray has sufficient cooling capacity to keep the Shelf cooled with a single fan failure. # 6.2.2 Autonomous Mode When no Shelf Manager is present, the Fans are controlled by the IPM controller. The fan speed depends on the setting of DIP switch on board. With a Micro DIP switch you can select either the exhaust temperature from the left Fan Tray or the fixed fan speed as reference to control the fan speed. By default the fixed speed of 50% full speed is used to determine the fan speed. When setting up the DIP switch, “1” stands for on and “0” stands for off. ![The image shows a small, black rectangular electronic component, likely a DIP switch, featuring three white square toggles arranged horizontally. Above the toggles, the text 'ON' is printed in white. Below each toggle, the numbers '1', '2', and '3' are printed in white. Three brass-colored metal pins extend from the bottom of the component.](.atca-80606pd-50-1g048-1000-10/ba8ddb00a8f8cc49bb7e478c031659c8994a6381a44f950216d848acc744056c.jpg) Table 4: Micro DIP switch settings

The Shelf Manager has access to these signals via IPMB. # 6.4 Fan Tray Indicators The front panel includes a green Fan Tray OK LED, a red Fan Tray Fault LED, and a blue Hot Swap LED. The Hot-Swap push button indicates to the Shelf Managers that the Fan Tray is about to be removed. Its use is optional, but it is provided so that service personnel can be trained to look for a blue LED to be illuminated on any active component before removing it from the system. Once the operator pushes the Hot Swap button, the Shelf Manager is informed of the pending extraction. When the Shelf Manager feels it is “safe“ to remove the Fan Tray, the blue Hot Swap LED illuminates solid. Table 5: LEDs on Fan Tray front panel

Before working ensure that the power is removed from the power connection cables. The Shelf supports Power Entry Modules (PEMs) with DC voltage power input. 日 The Shelf can be powered using a regular telecommunication power supply of -48/-60 VDC with a VDC return. The specified voltage range is from -40.5 VDC to -72 VDC. The Shelf supports redundant power supplies but the two supplies should be independently powered. # 7.1 Introduction Two pluggable DC power modules are located at the rear bottom side of the Shelf. The power supply modules are plugged-in from the rear side and are hot-swappable. To provide a redundancy they are arranged in a 1+1 configuration. # 7.2 Power Distribution Figure 7: Power Distribution ![**Blocks:**\n* **Fan Tray 1** (Vertical bar on the left)\n* **ShMgr1** (Top left)\n* **SAP** (Top center)\n* **ShMgr2** (Top right)\n* **Node Slot 6** (Blue box, top of middle column)\n* **Node Slot 5** (Greenish box)\n* **Node Slot 4** (Blue box)\n* **Node Slot 3** (Greenish box)\n* **Hub Slot 2** (Blue box)\n* **Hub Slot 1** (Greenish box)\n* **Fan Tray 2** (Vertical bar on the right)\n* **PEM A** (Bottom left, containing 'Branch 1' and 'Branch 2')\n* **PEM B** (Bottom right, containing 'Branch 1' and 'Branch 2')\n\n**Connections:**\n* **Fan Tray 1** connects via green lines to **ShMgr1**, **Node Slot 5**, **Node Slot 3**, **Hub Slot 1**, **PEM A (Branch 2)**, and **PEM B (Branch 2)**.

Each PEM provides power terminals for 75A power feed. Each power feed consists of a –48 VDC cable and its corresponding return cable. The feed is protected by a 60 A fused switches. The power is divided in 2 output branches towards the backplane. Overcurrent protection is provided by 40 A fuses in output each branch. The power filtering consists of filtered power terminals and a discrete line-filter for each power branch. The input voltage range for the Shelf is from -40VDC to -72VDC.In each power feed, voltage measurement is implemented, by means of a dedicated voltage monitor device. The PEM (together with all shelf related FRUs) are protected against wrong polarity up to +57 V DC, but it does not block wrong polarity voltage being applied to shelf-related FRUs and to Zone 1 power wiring of payload slots. Suppressor diodes are included in the feed chain that provide protection against a K.20 pulse of 500 V being applied to its input (K.20 surge pulse, "Basic level", Table 7, pulse type 7.3, 500 V applied to -48V and -48V RTN branches at the same time against shelf ground) so that the PEM itself and other shelf-related FRUs can sustain this level of pulse.

For maximum fault tolerance, the two DC PEMs should be independently powered by a separate Feed A and Feed B. A single DC PEM is capable of supplying the 335 watts of power to each blade slot and the necessary power for the PEMs, Fan Trays, and Shelf Managers. If two DC PEMs are in service, each DC PEM is hot-swappable after removing the power input cables from the DC PEM. # 7.3.2 DC PEM Signals The DC PEM provides signals for: • Voltage monitoring • Current monitoring Circuit Breaker Trigger Status • Fuse Monitoring Status of the Hot Swap Controller • Temperature The I²C devices on the DC PEM board are connected to Master-Only I²C bus of the Fan controller board. The Shelf Manager has access to these signals via IPM Bus of Fan Tray. # 7.3.3 DC PEM Indicators The front panel includes the following indicators: • In-Service LED (green) Out-of-Service LED (red) • Hot Swap LED (blue) Table 8: LEDs on DC PEM front panel

# 8 Thermal # 8.1 System Airflow Path The 6 slots ATCA Shelf provides an airflow using two Fan Trays at right and left sides of the Shelf. Each Fan Tray has 6 fans moving air from the right side to the left side of the Shelf in a push-pull arrangement. This arrangement provides excellent airflow as well as fault tolerance in the unlikely event of a fan failure.

Upon request also a version with on-blade shelf management is available. With on-blade shelf management, the I²C components of the PEMs and the SEEPROM are connected to the internal I²C bus on the Fan Trays. The on-blade Shelf Manager has access to these components via the IPM controller of the Fan Trays.

For explicit software documentation refer to: • Pigeon Point Shelf Manager User Guide • Pigeon Point Shelf Manager External interface Reference # 9.2 Introduction The Shelf Manager is a 78mmX280mm board that fits into a dedicated Shelf Manager slot in an ATCA Shelf. The Shelf Manager has two main responsibilities: 1. Manage/track the FRU population and common infrastructure of a Shelf, especially the power, cooling and interconnect resources and their usage. 2. Enable the overall system manager to join in that management/tracking through the System Manager Interface, which is typically implemented over Ethernet. The Shelf management based on the Pigeon Point Shelf management solution for AdvancedTCA products. The Shelf management software executes on the pigeon point Shelf Management Mezzanine 700 (ShMM-700), a compact SO-DIMM form-factor module, installed on the carrier board. The carrier board includes several on-board devices that enable different aspects of Shelf management based on the ShMM-700. These facilities include I2C-based hardware monitoring/control and GPIO expander devices. To maximize availability, the ATCA Shelves are designed to work with two redundant Shelf Managers.
