# 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:** Busied IPMB\n\n**Blocks:**\n* Six vertical rectangles labeled 'ATCA Board'.\n* Inside each 'ATCA Board' is a smaller rectangle labeled 'IPMC'.\n* Two large rectangles at the bottom labeled 'Shelf Manager 1' and 'Shelf Manager 2'.\n* A legend box containing 'IPMB-A' (next to a dashed line) and 'IPMB-B' (next to a solid line).\n\n**Connections:**\n* A horizontal bus line runs across the middle of the diagram.\n* From each 'IPMC', a vertical line extends downwards to the bus. The lines alternate in style: Solid, Dashed, Solid, Dashed, Solid, Dashed (from left to right).\n* From 'Shelf Manager 1', two vertical lines extend upwards to the bus: one dashed and one solid.\n* From 'Shelf Manager 2', two vertical lines extend upwards to the bus: one dashed and one solid.](.atca-80606pa-50-1g047-1000-10/8b26e5f1efb414812a3e271132fecb46516d74dcd5e573fa57a83260d1d8da42.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-80606pa-50-1g047-1000-10/304e16100846eae59c57637945c9b4fef9dd6af2443c309f49a985bd8cf85aed.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 numbered parts and structural details.](.atca-80606pa-50-1g047-1000-10/a5063761a0c965b780196186a923d8405ccf6e61c7dbbaf0718478857b80a1f5.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-80606pa-50-1g047-1000-10/d0cf93e93a725879029bcd04182d68e1ec247295ce6d487365233b9305d7a89d.jpg) 日 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 onboard IPM controller. Figure 5: Fan Tray ![Technical diagram of a server rack with labeled components and red annotations pointing to numbered parts](.atca-80606pa-50-1g047-1000-10/ccf00ae7429af259c0faf0e1c49e4dedb3b0878b1917249eabf859c967295d0b.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 onboard 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 black rectangular electronic component, specifically a 3-position DIP switch. The word 'ON' is printed in white at the top center. Below this are three white rectangular toggle switches. Underneath the toggles, the numbers '1', '2', and '3' are printed in white from left to right. Three brass-colored metal pins extend downwards from the bottom of the component.](.atca-80606pa-50-1g047-1000-10/92c5492f4876c37b48dafe1319ba135ad948d089c30a5acb7784e0c1e790eb41.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 Power Supplies are not included with the Shelf. The Shelf accepts Huawei R4850 serial power supplies. The Shelf can be powered with 230VAC line voltage or 240HVDC input depending onPSU type. # 7.1 Introduction Two pluggable AC power supplies are located at the front bottom side of the Shelf. The power supply units are plugged-in from the front side and are hot-swappable. To provide a redundancy they are arranged in a 1+1 configuration. The Output voltage of the PSUs is 53.5V DC. Because the nominal supply voltage for ATCA systems acc. to the PICMG specification is 48V DC, all signal names in this Manual with exception of this chapter are related to 48V DC. The PSUs are plugged into a Power Distribution Board (PDB) where the power is divided in 2 output branches towards the backplane. The power input is provided by an AC mains/line module with IEC 320-C20 connector with switch. The R4850XX series PSU only support communication on the CAN bus, but not support communication on the I2C bus, on the Power Distribution Board, there is one functional modular to implement the CAN bus to I2C bus bridge so that the R4850XX series PSU can be managed through the I2C bus. # 7.2 Power Distribution Figure 7: Power Distribution ![The flowchart depicts a system with two power supply units (PSUs), two connectors, and a bus bridge.\n\n**Labeled Blocks:**\n* **PSU1** (Blue rectangle, top left)\n* **PSU2** (Blue rectangle, bottom left)\n* **J2** (Grey rectangle, top right)\n* **J 10** (Grey rectangle, bottom right)\n* **CAN I2C Bus Bridge** (Yellow square, center)\n* **AC Input** (Text label, appearing twice)\n\n**Connections:**\n* **PSU1** connects via black lines labeled **-53.5 V** and **RTN** to **J2**.

The Shelf Manager can monitor the PSUs through the IPMC of the fan tray. The fan tray access the PSUs through an I2C bus to CAN bus bridge on the Power Distribution Board, since the PSUs only support CAN bus communication. Table 8: Basic Specifications for the PSUs

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 onboard 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.
