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.

2 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. 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.

3 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) 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.

4 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).

5 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.
