Electronics Protection Pigeon Point BMR-AST-ATCA Reference Design Page 2 / 9 The BMR-AST-ATCA Design is one of a series of Pigeon Point Board Management Reference (BMR) designs. This member of the series provides an IPM Controller (IPMC) or Carrier IPMC for AdvancedTCA and custom derivative architectures; it is based on the ASPEED AST2500 integrated remote management processor from ASPEED Technology.

2 This Design includes support for the advanced remote redirection facilities of the AST2500, which allow remote keyboard, video and mouse (KVM) hardware, as well as remote media, to be used as if it were attached to the local main CPU, potentially greatly simplifying management of large numbers of blade servers that integrate such IPMCs. The subset variant AST2520 is also supported, but without the remote redirection features, since it does not include the necessary hardware. This Reference Design is delivered in a Pigeon Point Board Management Starter Kit (which is detailed in a separate Product Brief). The kit includes: Schematics for the core of an IPMC based on an ASPEED 2500 family device, ready to be adapted for your board or other intelligent Field Replaceable Unit (FRU)

3 Linux-based foundation layer adapted for operation on the ASPEED-based IPMC Linux-based IPMC application firmware, delivered in source form and with development tools ready for simple and quick adaptation to your requirements One-stop support from Pentair experts for schematics, firmware and software used in developing and delivering your Pigeon Point BMR-based IPMC Complementary support, if needed, from ASPEED Technology for special hardware aspects of applying an AST2500 family device to the specific needs of your board The photo above shows the core of a BMR-AST IPMC. The key active components are: The AST2500 integrated remote management processor External DRAM and Flash Dual IPMB buffers to isolate the IPMC from the dual redundant IPMB-0 implemented on the backplane An IPMC implemented with this solution can be a Carrier IPMC, with the additional capability of managing subsidiary intelligent modules, each incorporating a Module Management Controller (MMC).

4 The next photo shows a Reference implementation of two instances of the carrier-based logic that hosts a module site. Each site or pair of sites is managed by a special module hot swap controller from Texas Instruments, the TPS2359.

5 Compliance tested with Polaris Networks ATCA and AMC Testers Highly adaptable, including for custom, derivative management architectures Usable for blades in bladed systems or for main system boards in non-bladed systems, such as appliances Independent of number, size and physical form factors of boards Board hot swap support available, but need not be used Interface to higher level management can be based on either I2C or Ethernet, among other options Allows integration of standards-based boards with proprietary architecture boards within a single bladed system, if desired Custom derivative management architectures can leverage support for intelligent hot swappable subsidiary modules, with similar potential for integrating both standards-based modules and proprietary modules, if desired Substantial CPU power can potentially support additional customer management applications Full support for core IPMC hardware requirements 32-bit ARM11 processor operating at 600 MHz IPMI-aware monitoring of designated AST2500 analog sensors Supports AST2500/2520 variants, with reduced features for AST2520 Payload voltage monitoring (including 48V supply) Support for external digital (DS75 or AD7417) thermal sensors Direct LAN attachment interface or sideband LAN attachment interface implemented via the standardized Network Controller Sideband Interface (NC-SI)

6 Capable of handling IPMI over LAN (including Serial over LAN, upgrades, IPMB trace access and other extensions) extended inactive state management, including extended management power support ATCA hot swap interfaces (handle and blue LED) Dual redundant IPMB-0 Hardware address detection from backplane FRU LED management Payload power supply controls (multiple voltage levels) Control of E-Keying governed fabric interfaces Optional persistence of above controls across IPMC resets Optional local System Event Log (SEL) Optional infrastructure for non-intelligent Rear Transition Modules UART-, LPC/KCS- or LPC/BT-based payload interface UART-based serial debug interface Full support for additional core Carrier IPMC hardware requirements Intelligent module (including AMC and IRTM)

7 Payload and management power control / monitoring for each module site, including payload power current measurement Tight compliance with specification constraints on power control, including fast trip circuits for payload and management power to quickly respond to serious fault conditions, disabling power within 300 ns Electronics Protection Pigeon Point BMR-AST-ATCA Reference Design Page 4 / 9 Control of fabric E-Keying governed interfaces, both for modules and for on-carrier switches terminating module links. Control of clock E-Keying governed interfaces, both for modules and for on-carrier clock-related devices Optional persistence of above controls across Carrier IPMC resets Management of on-carrier IPMB-L, the primary management communication path with the MMCs of installed modules Supports a separate logical IPMB-L segment for each module site, so that IPMB-L activity or problems on one leg do not affect the other legs Optional inclusion of additional AMC carrier-oriented hardware, such as a Base Interface Ethernet switch, in extended power domain.

8 With resulting coverage by extended inactive state management Optional support for advanced KVM and media redirection Leverages hardware support in the AST2500 Payload CPU uses USB and PCI Express (PCIe) to connect with AST2500 ports; AST2500 can redirect normal KVM and media operations on those ports to remote physical devices (typically on a LAN-connected remote management console) With appropriate configuration, unmodified OS and application software on Payload CPU can use redirected peripherals transparently As shown in diagram below, two USB ports and a PCI Express (PCIe) port on the Payload CPU interacts, through the IPMC Ethernet interface, with a remote console as if the remote keyboard/mouse, installation drive and video monitor were directly attached to the Payload CPU.

9 Optional support for special purpose functionality Telco (dry contact) alarm management, including choice of IPMI interfaces: ATCA-defined or Pigeon Point specific Shelf FRU information SEEPROM access Small footprint Core IPMC can fit in the following footprint: 43mm x 49mm AMC site-specific logic for a pair of sites can fit in about 700mm2, including a TPS2359 supporting both sites Comprehensive, readily adaptable firmware All mandatory and many optional IPMI/ATCA/AMC commands supported over the backplane IPMB-0 and IPMB-L Carrier IPMC manages installed AMCs and represents them to the Shelf Manager as defined by , with similar representation extended to the carrier payload Numerous Pigeon Point extension commands, primarily used over the payload and serial debug interfaces Payload alert notifications over payload interface for sensor events and receipt of reset/shutdown commands PICMG firmware upgrade support Simple but highly flexible configuration of firmware features Electronics Protection Pigeon Point BMR-AST-ATCA Reference Design Page 5 / 9 Sophisticated, support for firmware upgrades Firmware upgrades over any IPMI interface to the IPMC.

10 With redundant copies and automatic fallback after failed upgrade IPMC is fully functional during upgrade Bootloader can be upgraded without using JTAG Framework for managing firmware upgrades that include changes in data structures that are preserved across IPMC resets to eliminate disruptive upgrades IPMC FRU Information implemented as additional component, allowing FRU Information upgrades independently of firmware Optional upgrades via IPMI over LAN interface Open source ipmitool supplied as upgrade agent compliance means that any compliant upgrade agent can upgrade any compliant IPMC Support for either non-intelligent or intelligent Rear Transition Modules (RTMs) Includes specific hardware and firmware support for interface between front board and non-intelligent RTM (that is, one with no Module Management Controller or MMC) Support for intelligent RTMs (that is, MMC-equipped) using built-in Carrier IPMC hardware and firmware support Allows compliance with ATCA requirements regarding how an RTM is represented by the IPMC Choice of serial interface protocols (SIPL variants) supported via UARTs to payload processor and serial debug interface SIPL-TM, based on IPMI-defined Terminal Mode of the Serial/Modem Interface, SIPL-BM based on IPMI-defined Basic Mode, Either protocol selectable individually for either serial interface SIPL-TM.
