通用硬件平台及相应的架构系统和先进夹层卡供电方法
本申请要求于 2007 年 10 月 30 日提交中国专利局、 申请号为 200710164395.9 , 发明名称为"通用硬件平台及相应的架构系统和先进夹层卡 供电方法"的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及通用硬件平台以及基于该平台的通用硬件平台架构系统和先 进夹层卡供电方法。
背景技术
为满足电信和计算等应用中对集中计算和处理的需求，基于模块应用的灵 活性以及通用化、标准化等特点，提出了电信和计算通用硬件平台架构（TCA: Telecommunications Computing Architecture ), 其中具体包括高级通用硬件平台 架构（ ATCA: Advanced TCA )和小型通用硬件平台架构（ MTCA: Micro TCA ) 等类型。
以 MTCA系统为例， 基本结构如图 1所示， 包括 MTCA平台和先进夹层 卡（ AMC： Advanced Mezzanine Card )。 MTCA平台通常包括机框和平台管理 服务系统，其中机框为系统各模块提供物理结构支持以及所使用的电源和信号 通道等， 平台管理服务系统提供 AMC的管理和运行环境， 主要包括交换控制 模块（ MCH: MTCA Carrier Hub )和电源模块（ PM: Power Module )。 以下， 参照图 1 , 对 MTCA系统的各个部分进行说明：
机框： 机框通过背板为 MTCA系统的各个模块提供连接接口和相互之间 的连接通道， 其中包括： 提供给 AMC的插接口， 如图 1中的接口 1和接口 2; 连接 MCH 和其他各模块的智能平台管理总线 （IPMB: Intelligent Platform Management Bus ), 包括连接 MCH和 PM的 IPMB-0与连接 MCH和 AMC的 IPMB-L; 连接 PM和各个插接口的硬件信号通道和负载电源通道。 图 2是各 模块在机框中的排布形式的一个示例， 图 2中机框包括" Tier 2 (层 2 ) "和" Tier 1 (层 1 ) "上下两层， 有 14个槽位， 位于槽位 1的两个电源模块 PM1和 PM3 分别给 Tier 1和 Tier 2的插接口供电，位于槽位 2的 MCH对电源模块 PM1和 PM3和 AMC进行管理， 位于槽位 13和 14的 MCH和 PM2、 PM4与槽位 2 和 1的 MCH和 PM1、 PM3互为冗余，槽位 3 ~ 12的 20个插接口提供给 AMC。 显然 MCH和 PM可以釆用可插拔模块的方式连接到机框上， 为清楚起见， 本 文中所称插接口指机框为 AMC提供的插接口。
AMC : AMC 通常支持热插拔， 是一种现场可更换单元 （FRU: Field Replaceable Unit ),具体类型包括数字信号处理（ DSP: Digital Signal Processing ) AMC、 中央处理器（ CPU ) AMC、 网络处理器（ NP: Network Processor ) AMC、 接口 AMC、存储 AMC等。通常使用的 AMC规格如图 3所示，包括双宽全高、 双宽半高、 单宽全高、 单宽半高四种。 在 MTCA系统中不同规格的 AMC可 混合配置， 根据需要进行机框槽位的分配， 例如， 图 2中的槽位 3和 4可以支 持 1个全高双宽 AMC,或者 2个半高双宽 AMC,或者 1个半高双宽 AMC + 2 个半高单宽 AMC, 或者 4个半高单宽 AMC。 目前， 如图 4所示， 单宽和双宽 的 AMC均只提供一个连接器， 即标准连接器 40, AMC可以通过标准连接器 40 直接插到机框背板的插接口上。 标准连接器区包括负载电源通道的接口、 硬件信号通道的接口 （例如检测 AMC在位的 PS1 ( Present Signal 1 )在位信 号 1 ) 以及 AMC上的模块管理控制器（MMC: Management Controller )与软 件信号通道 IPMB-L的接口等， 关于 AMC的标准连接器区具体的管脚定义和 信号交互等内容可参考 AMC.0规范。 此外， 如图 5所示， 还为 AMC定义了 可设计辅助连接器的辅助连接器区二 （AMC ZONE 2 ) 和辅助连接器区三 ( AMC ZONE 3 )。
PM: PM 负责通过与各个插接口连接的负载电源通道为插接口上连接的 AMC提供负载电源， 通常为 +12V电源。 PM上通常设置有增强模块管理控制 器（EMMC: Enhanced Management Controller ), 能够根据从硬件信号通道获 取的插接口的 AMC在位检测信号等信息为相应的插接口提供负载电源。
MCH: MCH上设置有 MTCA承载管理控制器（MCMC: MTCA Carrier Manager Controller ), MCMC通过 IPMB-L与各个 AMC的 MMC连接， 实现 MCH对各 AMC的管理； MCMC通过 IPMB-0与 PM的 EMMC连接， 实现 MCH对 PM的管理。
在对现有技术的研究和实践过程中， 限于 AMC标准连接器的定义， 现有 TCA系统中提供的与 AMC标准连接器适配的 TCA平台不能满足 AMC可能 出现的多样化功能电源需求（本文中， 将 AMC在负载电源需求之外的其他类 型的电源需求称为功能电源需求），例如 +48V的以太网供电（POE: Power Over Ethernet ) 电源、 90V 20Hz的交流振铃电源等， 限制了 AMC功能的扩展。 发明内容

具体实施方式
本发明实施例提供一种通用硬件平台， 其基本结构如图 6所示， 包括： 背板 001 , 用于提供负载电源通道 B和信号通道 C。 本文中， 负载电源通道 指按照通常的规范， 背板上用来提供负载电源的电源通道。 背板 001通过若干 个插接口 A-1 ~ A-n来向先进夹层卡 AMC提供负载电源通道 B和信号通道 C;
AMC通过一个或一个以上的插接口插接到背板上以后，即可与负载电源通道 B 和信号通道 C连接；
平台管理服务系统 002, 用于通过信号通道 C获取插接在背板上的 AMC的 供电需求信息； 根据获取的供电需求信息确定所连接的 AMC的功能电源需求； 按照确定的功能电源需求通过与 AMC连接的负载电源通道 B , 向 AMC提供相 应的功能电源。
下面， 对上述基本结构进行分析。 清楚起见， 以下将具有功能电源需求的 AMC称为功能 AMC。 上述通用硬件平台提供的逻辑结构满足： ①识别插入到背板上的功能 AMC。
识别所使用的供电需求信息可以釆自单个插接口， 也可以釆自多个插接 口。供电需求信息可以是软件信号也可以是硬件信号，或者是两种信号的综合。 供电需求信息的内容和连接方式可釆用如下两种定义方式：
a、 专门定义。 这种情况下， 背板需要提供专用的连接信号通道， 相应的 功能 AMC也需要在现有的标准连接器之外设计适配的辅助连接器， 可设计在 标准连接器的辅助连接器区二或辅助连接器区三。
b、 基于现有标准连接器提供的管脚和连接信号通道。 这种情况下背板的 结构可无须更改； 根据功能 AMC对背板提供的与标准连接器适配的插接口的 使用方式可具体分为如下两种情况：
bl、 功能 AMC通过对自身标准连接器提供的信号和管脚的复用来提供供 电需求信息， 此时， 背板仅需要为功能 AMC提供一个与标准连接器适配的插 接口， 本文中将这种与 AMC标准连接器适配的插接口简称为标准接口。
b2、 功能 AMC在标准连接器的辅助连接器区二或辅助连接器区三设计辅 助连接器来提供供电需求信息， 此时， 背板需要为功能 AMC提供两个标准接 口。
②为功能 AMC提供功能电源。
可以使用专门的电源模块 ,也可以扩展原有提供负载电源的电源模块的输 出能力来提供功能电源。本发明中背板通过共享负载电源通道的方式来输出功 能电源， 这种情况下背板的结构可无须更改； 功能 AMC可通过对自身标准连 接器提供的负载电源通道的复用来获得功能电源，另外通过对输入的功能电源 进行转换获得负载电源， 此时结合前述情况 bl , 背板仅为功能 AMC提供一个 标准接口； 当然， 功能 AMC也可以通过在标准连接器的辅助连接器区二或辅 助连接器区三设计的辅助连接器来输入功能电源， 此时结合前述情况 b2, 背板 为功能 AMC提供两个标准接口。
当然，上述各种不同的识别和电源提供方式也可以在同一通用硬件平台中 混合使用， 例如， 可在背板上同时配置不同类型的插接口， 根据插接口的类别 按照对应的方式进行管理，插接口类型包括： 提供给仅使用一个标准连接器的 功能 AMC的插接口（该类插接口兼容使用标准连接器的普通 AMC ); 提供给使 用一个标准连接器和一个辅助连接器 (该辅助连接器兼容标准连接器设计 )的 功能 AMC的插接口组合（该类插接口组合中的两个插接口均兼容使用标准连 接器的普通 AMC ); 提供给使用一个标准连接器和一个辅助连接器（该辅助连 接器不兼容标准连接器设计） 的功能 AMC的插接口组合。
上述通用硬件平台为 AMC供电的方法可归纳为： 通过背板提供的信号通 道获取插接在背板上的先进夹层卡的供电需求信息；根据所述供电需求信息确 定所述先进夹层卡的功能电源需求；按照确定的功能电源需求通过背板提供的 与所述先进夹层卡连接的负载电源通道，向所述先进夹层卡提供相应的功能电 源。
以下分别对基于上述基本结构的通用硬件平台和通用硬件平台架构系统 进行详细说明。
实施例一、一种通用硬件平台， 本实施例中的通用硬件平台提供软件信号 通道来传输 AMC的供电需求信息， 逻辑结构如图 7所示， 包括背板 11和平台管 理服务系统， 本实施例平台管理服务系统包括交换控制模块 12和电源模块 13。
背板 11 , 用于提供负载电源通道 B1和第一管理总线 C1 ; 提供连接交换控 制模块 12和电源模块 13的第二管理总线 Dl。 背板 11通过若干个插接口 Al-1 ~ Al -n来向 AMC提供负载电源通道 B 1和第一管理总线 C 1。
交换控制模块 12, 用于通过与 AMC连接的第一管理总线 C1获取 AMC的电 源配置信息； 通过第二管理总线 D1将获取的电源配置信息反馈到电源模块 13。 由于 AMC可以通过一个或一个以上的插接口插接到背板 11上， 为描述清楚起 见， 假定 AMC使用的插接口之一为 "接口一"， 交换控制模块 12通过属于接口 一的第一管理总线 C 1获取 AMC的电源配置信息。
电源模块 13 ,用于根据交换控制模块 12提供的电源配置信息确定与接口一 连接的 AMC的功能电源需求； 按照确定的功能电源需求通过与该 AMC连接的 负载电源通道 B1向该 AMC提供相应的功能电源。 当然， 被用来向 AMC提供功 能电源的负载电源通道 B1可以选择属于接口一的负载电源通道， 也可以选择 属于与该 AMC连接的其他插接口的负载电源通道。
电源模块 13具体可釆用如图 8所示的结构， 包括：
电源电路 131 , 用于对输入电源进行转换， 转换后的电源包括一种或一种 以上的功能电源；
增强模块管理控制器 EMMC 132, 用于通过第二管理总线 D1获取 AMC的 电源配置信息， 根据获取的电源配置信息确定 AMC的功能电源需求， 按照确 定的功能电源需求生成软件控制信号；
控制电路 133 , 用于根据增强模块管理控制器 132的软件控制信号， 将相应 的一种转换后的电源提供给与 AMC连接的某一条负载电源通道 B 1。
电源模块 13可仅考虑输出功能电源， 当然也可以兼容输出负载电源， 这种 情况下， 将图 8中电源电路 131输出的某一路功能电源更换为 12V负载电源输出 即可， 此时负载电源通道 B1可被选择输出功能电源和负载电源。
下面， 对本实施例通用硬件平台的结构进行分析。
①识别插入到背板上的功能 AMC。
背板 11提供的第一管理总线 C1作为获取 AMC的供电需求信息的软件信号 通道， 可以基于现有的软件信号通道 IPMB-L定义， 这样， 接口一中与识别功 能 AMC有关的部分的设计与现有标准接口的设计兼容。 背板 11提供的第二管 理总线 D1可以基于现有的软件信号通道 IPMB-0定义， 交换控制模块 12的 MCMC按照 IPMB -0定义的方式与电源模块 13的 EMMC通讯。
AMC中存储的 FRU信息， 在功能 AMC中， 该 FRU信息中包含有新增的电源配 置信息， 其具体内容可以是该功能 AMC所需要的功能电源的标识信息或其它 配置信息等。
②为功能 AMC提供功能电源。
在本实施例中，通用硬件平台可以通过属于接口一的第一管理总线获取功 能 AMC的识别信息， 再通过属于另一插接口 （假定为接口二） 的负载电源通 道向功能 AMC提供功能电源。 这种情况下， 接口一可按照标准接口设计， 接 口二可按照标准接口设计 (负载电源通道被选择输出负载电源和功能电源 ), 也可以专门设计。 基于现有 AMC的规格， 接口二可位于接口一的辅助连接器 区二， 相应的功能 AMC为全高规格； 或者， 接口二可位于接口一的辅助连接 器区三， 相应的功能 AMC为双宽规格。
在本实施例中， 通用硬件平台也可以既通过接口一获取功能 AMC的识别 信息， 又通过接口一向功能 AMC提供功能电源。 这种情况下， 负载电源通道 被选择输出负载电源和功能电源，接口一可按照标准接口设计， 只是相应的功 能 AMC中需要设计电源转换电路，对输入的功能电源进行转换获得负载电源， 以满足负载电源需求。 这种结构下， 功能 AMC无须使用辅助连接器。
通过上述分析可知， 背板提供的插接口可以包括不同的类型， 并不是所有 插接口都需要与 C1连接； 例如， 若背板上某些插接口专用于向功能 AMC提供 功能电源， 则这种类型的插接口由于不需要与平台服务系统进行软件信号交 互， 因此可以不支持与 C1的连接。
下面给出基于实施例一通用硬件平台的通用硬件平台架构系统， 如图 9所 示，包括通用硬件平台和先进夹层卡 14;通用硬件平台釆用实施例一中的结构， 包括背板 11、 交换控制模块 12和电源模块 13; 先进夹层卡 14包括连接器 141和 模块管理控制器 MMC 142;
背板 11 , 用于提供负载电源通道 B1和第一管理总线 C1 ; 提供连接交换控 制模块 12和电源模块 13的第二管理总线 D1 ;
连接器 141 , 用于通过背板 11提供的一个或一个以上插接口， 插接在背板
11上；
模块管理控制器 MMC 142,用于通过连接器 141 ,以提供 FRU信息的方式， 向交换控制模块 12提供电源配置信息；
交换控制模块 12,用于通过与连接器 141连接的第一管理总线 C1获取 MMC 142提供的电源配置信息； 通过第二管理总线 D1将获取的电源配置信息反馈到 电源模块 13;
电源模块 13 ,用于根据获取的电源配置信息确定先进夹层卡 14的功能电源 需求； 按照确定的功能电源需求通过电源通道 B1 , 在与连接器 141连接的负载 电源通道上提供相应的功能电源。
基于实施例一中提供的通用硬件平台的结构， 连接器 141可以釆用一个标 准连接器的结构， 或者一个标准连接器加一个辅助连接器（位于辅助连接器区 二或三， 兼容标准连接器设计）的结构， 或者一个标准连接器加一个辅助连接 器（位于辅助连接器区二或三，不兼容标准连接器设计）的结构。 图 9中以 A1-1 作为获取 AMC的电源配置信息的接口一， 连接器 141示例性的釆用一个标准连 接器加一个兼容标准设计的辅助连接器的结构， 此时 B1可选择输出负载电源 和功能电源， 能够为与 A1-1连接的标准连接器提供负载电源， 因此图 9中画出 了 B1与标准连接器的连接关系。
本实施例中通过平台管理服务系统釆用软件信号通道对背板上插接的先 进夹层卡的供电需求信息进行识别，从而根据先进夹层卡的需求向其提供所需 要的功能电源。 由于釆用了基于信息识别的电源提供方式， 能够灵活的选择输 出功能电源， 充分满足先进夹层卡可能出现的多样化功能电源需求。 同时， 软 件识别信号的传输和功能电源的提供可兼容现有标准接口的定义进行设计，对 现有设备改动小， 容易实现。
实施例二、 一种通用硬件平台， 与实施例一相比， 本实施例中的通用硬件 平台除了提供软件信号通道以外还提供硬件信号通道来传输 AMC的供电需求 信息， 逻辑结构如图 10所示， 包括背板 21和平台管理服务系统， 本实施例平台 管理服务系统包括交换控制模块 22和电源模块 23。
背板 21 , 用于提供负载电源通道 B2、 第一管理总线 C2和硬件信号通道 E2; 提供连接交换控制模块 22和电源模块 23的第二管理总线 D2。 背板 21通过若干 个插接口来向 AMC提供负载电源通道 B2和第一管理总线 C2， 图 10中示例性的 画出了两个插接口 A2-1和 A2-2。
交换控制模块 22, 用于通过与 AMC连接的第一管理总线 C2获取 AMC的电 源配置信息； 通过第二管理总线 D2将获取的电源配置信息反馈到电源模块 23。 由于 AMC可以通过一个或一个以上的插接口插接到背板 21上， 为描述清楚起 见， 假定 AMC使用的插接口之一为 "接口一"， 交换控制模块 22通过属于接口 一的第一管理总线 C2获取 AMC的电源配置信息。
电源模块 23 , 用于通过与 AMC连接的硬件信号通道 E2获取 AMC的在位检 测信号； 根据交换控制模块 22提供的电源配置信息以及通过硬件信号通道 E2 获取的在位检测信号，确定是否需要在与提供在位检测信号的硬件信号通道 E2 属于同一插接口的负载电源通道 B2上提供相应的功能电源； 按照确定的结果 在负载电源通道 B2上提供相应的功能电源。 假定提供 AMC的在位检测信号的 硬件信号通道 E2属于接口二，接口二与接口一可以是同一个插接口，或者接口 二可以是接口一以外的另一插接口。在后一种情况下， 可以通过预先规定的槽 位分配方式来确定接口一和接口二的关联关系， 例如，对于两层结构的背板可 以将位于背板上下两层的相邻两个插接口作为接口一和接口二， 相应的功能
AMC釆用双宽规格， 具有标准连接器和位于辅助连接器区三的辅助连接器； 也可以将位于背板同一层的相邻两个插接口作为接口一和接口二，相应的功能 AMC釆用全高规格， 具有标准连接器和位于辅助连接器区二的辅助连接器。 清楚起见， 图 10中以 A2-1作为接口一， 以 A2-2作为接口二。
电源模块 23具体可釆用如图 11所示的结构， 包括：
电源电路 231 , 用于对输入电源进行转换， 转换后的电源包括一种或一种 以上的功能电源；
增强模块管理控制器 EMMC 232, 用于通过第二管理总线 D2获取 AMC的 电源配置信息， 根据获取的电源配置信息确定 AMC的功能电源需求， 按照确 定的功能电源需求生成软件控制信号；
控制电路 233 , 用于通过属于接口二 A2-2的硬件信号通道 E2获取插接在接 口二 A2-2上的 AMC的在位检测信号； 用于根据增强模块管理控制器 132的软件 控制信号和接口二 A2-2上的在位检测信号，将相应的一种转换后的电源通过属 于接口二 A2-2的负载电源通道 B2提供给 AMC。
清楚起见， 图 11中只画出了电源模块 23到一个插接口的一路输出， 多个插 接口的情况可类推。 此外， 为提高电源输出控制的可靠性， 硬件信号通道 E2 提供的在位检测信号， 也可以同时提供给增强模块管理控制器 EMMC 232, 与 电源配置信息一起作为其判断 AMC的功能电源需求的依据， 该部分连接在图
11中以虚线画出。
与实施例一中类似， 电源模块 23可仅考虑输出功能电源， 当然也可以兼容 输出负载电源， 这种情况下， 将图 11中电源电路 231输出的某一路功能电源更 换为 12V负载电源输出即可， 当然， 相应的 EMMC 232, 还可以生成控制负载 电源输出的软件控制信号， 此时属于接口二 A2-2的负载电源通道 B2成为功能 电源和负载电源的共享通道， 控制电路 233根据软件控制信号和在位检测信号 选择在属于接口二 A2-2的电源通道 B2上输出负载电源或者一种功能电源。
下面， 对本实施例通用硬件平台的结构进行分析。
①识别插入到背板上的功能 AMC。 本实施例中， 对从软件信号通道 C2获取的供电需求信息部分的分析与实 施例一类似。背板 21提供的传输在位检测信号的硬件信号通道 E2可以基于现有 的检测 AMC在位的 PS1信号来定义， 这样， 接口二 A2-2中与识别功能 AMC有 关的部分的设计与现有标准接口的设计兼容。 由于 PS1信号属于标准槽位定义 范围， 因此图 10中同样为接口一 A2-1连接了硬件信号通道 E2。 显然， 在接口 二与接口一是同一插接口的情况下， 即识别功能 AMC的软件和硬件通道属于 同一插接口， 该插接口也能够与现有标准接口的设计兼容。
②为功能 AMC提供功能电源。
本实施例中， 对功能电源的提供的分析与实施例一类似， 不再赘述。
下面给出基于实施例二通用硬件平台的通用硬件平台架构系统， 如图 12 所示， 包括通用硬件平台和先进夹层卡 24; 通用硬件平台釆用实施例二中的结 构， 包括背板 21、交换控制模块 22和电源模块 23;先进夹层卡 24包括连接器 241 和模块管理控制器 MMC242;
背板 21 , 用于提供负载电源通道 B2、 第一管理总线 C2和硬件信号通道 E2; 提供连接交换控制模块 22和电源模块 23的第二管理总线 D2；
连接器 241 , 用于通过背板 21提供的一个或一个以上插接口， 插接在背板 21上；
模块管理控制器 MMC 242,用于通过连接器 241 ,以提供 FRU信息的方式， 向交换控制模块 22提供电源配置信息；
交换控制模块 22,用于通过与连接器 241连接的第一管理总线 C2获取 MMC
242提供的电源配置信息； 通过第二管理总线 D2将获取的电源配置信息反馈到 电源模块 23;
电源模块 23 ,用于通过与连接器 241连接的硬件信号通道 E2获取 AMC的在 位检测信号； 根据获取的电源配置信息以及 AMC的在位检测信号， 确定是否 需要在与提供在位检测信号的硬件信号通道 E2属于同一插接口的负载电源通 道 B2上提供相应的功能电源； 按照确定的结果在负载电源通道 B2上提供相应 的功能电源。 假定获取 AMC的电源配置信息的第一管理总线 C2属于接口一， 提供 AMC的在位检测信号的硬件信号通道 E2属于接口二：
①若接口二是接口一以外的另一插接口； 则连接器 241包括一个标准连接器和一个辅助连接器， 辅助连接器位于标 准连接器的辅助连接器区二或者辅助连接器区三；标准连接器用于提供与接口 一的连接接口，辅助连接器用于提供与接口二的连接接口。 图 12以这种情况画 出， 并且假设 B2能选择输出功能电源与负载电源， 因此同样为接口一 A2-1连 接了 B2。
②若接口二与接口一是同一插接口；
则先进夹层卡 24还需要包括电源转换模块 243 ,该模块示意图如图 13所示， 用于对从连接器 241输入的功能电源进行转换， 转换后的电源包括负载电源和 功能电源， 分别提供给相应的功能电路和负载电路使用。
本实施例中通过平台管理服务系统釆用软件和硬件信号通道对背板上连 接的先进夹层卡的供电需求信息进行识别，从而根据先进夹层卡的需求向其提 供所需要的功能电源。 由于釆用了基于信息识别的电源提供方式， 能够灵活的 选择输出功能电源， 充分满足先进夹层卡可能出现的多样化功能电源需求。 同 时， 识别信号的传输和功能电源的提供可兼容现有标准接口的定义进行设计， 对现有设备改动小， 容易实现。
为更好的理解实施例二，下面分别就接口一与接口二不是同一插接口和是 同一插接口的情况给出实际应用的例子。 在应用例中， 假定功能 AMC的功能 电源需求为 +48 V的 POE电源。
示例一、 适用于双宽规格的功能 AMC的 MTCA系统， 系统逻辑结构示意 图如图 14所示。
该 MTCA系统的背板具有双层结构，上下两层相邻的插接口作为接口一和 接口二， 以上层 Tier2的插接口作为接口二， 以下层 Tierl的插接口作为接口一， 所有插接口均兼容标准接口设计。 相应的功能 AMC的连接器包括一个标准连 接器和一个兼容标准连接器设计的辅助连接器，辅助连接器位于标准连接器的 AMC ZONE 3连接器区， 提供 POE电源通道和硬件控制信号的连接， 对于功能 AMC内部如何支持 POE功能可参照电气和电子工程师协会的 802.3af标准来设 计， 本示例不做限定。 由于辅助连接器不需要支持 IPMB-L, 因此图 14中没有 画出 Tier 2连接辅助连接器的插接口上的 IPMB-L总线。 由于本示例分析过程中 不涉及 Tier 1的 PS1信号和供电方式， 因此图 14中也没有画出 Tier 1的硬件信号 通道和电源模块。
下面参照图 14对本示例系统的管理和控制过程进行详细描述：
图 14中给出了一个位于 Tier 2的普通单宽 AMC的连接情况、 一个双宽功能 AMC的连接情况和分别位于 Tier 1和 Tier 2的两个空插接口的连接情况。
传输 PS1信号的硬件通道（以下简称 PS1通道）分别连接位于 Tier 2的各插 接口和电源模块， PS1在电源模块内部被上拉， 当某一插接口插入普通单宽 AMC时， 普通单宽 AMC内部会把该 PS1信号线拉为低电平， 因此当电源模块 的 EMMC检测到某根 PS1线为低时， 可以判断该插接口有普通单宽 AMC插入， 从而控制为其提供负载电源输出。
本示例中， 利用 PS1的不同电平来判断双宽功能 AMC的插入， 即， 在双宽 功能 AMC内部把 PS1上拉到高电平。 当电源模块的 EMMC检测到某一 PS1为高 电平时， 该插接口可能插入了双宽功能 AMC或该插接口为空， 此时， 需要利 用双宽功能 AMC位于 Tier 1的连接，如 IPMB-L总线连接，来区分这两种可能情 况。 MCH可以通过 IPMB-L总线读取 Tier 1的槽位应用信息， 对于双宽功能 AMC , 在 FRU信息中会保存与 POE相关的电源配置信息， 双宽功能 AMC的 MMC可以读取到这些电源配置信息， 并且通过 IPMB-L总线与 MCH的 MCMC 进行通信， 反馈电源配置信息给 MCH , 因此 MCH可以获知该插接口插入了双 宽 POE模块。 MCH的 MCMC可以通过 IPMB-0总线把电源配置信息反馈给电源 模块的 EMMC , EMMC综合 PS1的电平以及利用 IPMB总线进行通信获得的电 源配置信息， 即可准确的判断某一插接口是否插入双宽功能 AMC。
在 Tier 2空插接口的情况下， 虽然 PS1也是高电平， 但 MCH无法通过 IPMB-L总线从对应的 Tier 1的插接口读取到电源配置信息 ,因此 MCH可以获知 该插接口没有插入双宽功能 AMC , MCH的 MCMC可以通过 IPMB-0总线把该信 息通知给电源模块的 EMMC,电源模块通过对 PS1信号和 IPMB交互信息的综合 分析， 可以判断某 Tier 2槽位是否为空槽位。
本示例中， PS1信号除了输入到 EMMC用于进行插入 AMC类型的判断外， 还作为硬件控制信号， 分别连接到各路电源的控制电路上 （控制电路中包括 POE电源控制部分和负载电源控制部分）， PS1为高电平是打开 POE电源的硬件 控制条件， PS1为低电平是打开负载电源的硬件控制条件。 另外， EMMC还根 据 PS 1信号的状态和通过 IPMB总线通信获得的信息， 在作出插入 AMC类型判 断后， 输出软件控制信号， 控制 POE电源和负载电源的开关（软件控制信号可 使用 POE使能信号 POE— EN和负载电源使能信号 POW— EN , POE— EN为高电平 是打开 POE电源的软件控制条件， POW— EN为高电平是打开负载电源的软件控 制条件）。 软 /硬件控制信号与电源输出的关系如表 1所示， 其中 0表示低电平， 1表示高电平。

Figure imgf000016_0002
综上所述， 本示例 MTCA系统对 Tier 2的 POE电源输出的管理和控制步骤 下：
1、 电源模块检测 PS1信号， 获取 PS1的电平状态； 当 PS1为低电平时， 判 断插入了普通单宽 AMC; 当 PS1为高电平时， 判断插入了双宽功能 AMC或没 有插入 AMC, 此时：
a ) 电源模块要求 MCH提供读取相应的 Tier 1插接口的模块信息， MCH通 过相应的 Tier 1插接口的 IPMB-L总线与位于 Tier 1的模块进行通信， 并通过 IPMB-0总线把信息反馈给电源模块。
b ) 电源模块根据 MCH反馈的信息， 例如是否有 POE电源配置信息， 判断 该 Tier 2插接口插入了双宽功能 AMC还是空插接口。
2、 电源模块根据对插入 AMC类型的判断， 输出相应的软件控制信号， 结 合硬件控制信号， 共同控制电源控制电路， 输出 AMC需要的电源到共享电源 通道上。
本示例中利用 AMC ZONE 3辅助连接器区实现 POE供电， 实际应用中， 也 可以利用 AMC ZONE 2辅助连接器区来实现 POE供电， 这种情况下， 接口一与 接口二是位于同一层中的两个相邻插接口， 对应的功能 AMC釆用全高规格， 连接和控制方式可参照本示例设计， 不再赘述。
示例二、 适用于使用单个标准连接器的功能 AMC的 MTCA系统， 系统逻 辑结构示意图如图 15所示。
该 MTCA系统的背板的插接口与对应的功能 AMC的连接器均兼容标准 AMC连接器区定义。 下面参照图 15对本示例系统的管理和控制过程进行详细 描述：
图 15中给出了一个普通单宽 AMC的连接情况、 一个单宽功能 AMC的连接 情况和一个空插接口的连接情况。
PS1通道分别连接各插接口和电源模块， PS1在电源模块内部被上拉， 普 通单宽 AMC内部把 PS 1信号线拉为低电平， 单宽功能 AMC内部也把 PS 1下拉到 低电平， 因此当电源模块的 EMMC检测到某一 PS1为低电平的时候， 该插接口 可能插入了普通单宽 AMC或单宽功能 AMC。
此时，对于单宽功能 AMC,在 FRU信息中还应该保存了与 POE相关的电源 配置信息， 单宽功能 AMC的 MMC可以读取到这些电源配置信息， 并且通过 IPMB-L总线与 MCH的 MCMC进行通信，反馈电源配置信息给 MCH,因此 MCH 可以获知该插接口插入了单宽功能 AMC。 MCH的 MCMC可以通过 IPMB-0总线 把电源配置信息反馈给电源模块的 EMMC, EMMC综合 PS1的电平以及利用 IPMB总线进行通信获得的电源配置信息， 即可准确的判断某一插接口是插入 普通单宽 AMC还是单宽功能 AMC。
本示例中，电源模块内部对输出电源的控制方式与示例一相同，不再赘述。 本示例中软 /硬件控制信号与电源输出的关系如表 2所示， 其中 0表示低电平， 1 表示高电平。 PS1 POE— EN POW— EN 电源输出 描述
0 0 0 所有电源关 正常状态
断， 无输出
0 0 1 输出 12V的 正常状态， 插入普通单宽 负载电源 AMC
0 1 0 输出 48V的 正常状态， 插入单宽功能
POE电源 AMC
0 1 1 非正常状态， 不允许出现
1 所有电源关 正常状态
断， 无输出
显然， 当插入单宽功能 AMC时， 单宽功能 AMC只能从共享电源通道上获 取 48V的 POE电源， 因此，单宽功能 AMC需要设计电源转换电路，从 48V的 POE 电源上转换得到内部需要的负载电源。
综上所述， 本示例 MTCA系统对 POE电源输出的管理和控制步骤如下：
1、 电源模块检测 PS1信号， 获取 PS1的电平状态， 当 PS1为低电平时， 判 断插入了普通单宽 AMC或单宽功能 AMC, 当 PS1为高电平时， 判断没有插入 AMC„
2、 当 PS1为低电平时， 电源模块要求 MCH读取相应插接口的模块信息， MCH通过相应插接口的 IPMB-L总线与模块进行通信，并通过 IPMB-0总线把模 块信息反馈给电源模块。
3、 电源模块根据 MCH反馈的模块信息， 例如是否有 POE电源配置信息， 判断该插接口是插入了普通单宽 AMC还是单宽功能 AMC。
4、 电源模块根据对插入 AMC类型的判断， 输出相应的软件控制信号， 结 合硬件控制信号， 共同控制电源控制电路， 输出 AMC需要的电源到共享电源 通道上。
通过上述实施例可以看出，本发明实施例通过平台管理服务系统对背板上 连接的先进夹层卡的供电需求信息进行识别 ,从而根据先进夹层卡的需求向其 提供所需要的功能电源。本发明实施例的通用硬件平台由于釆用了基于信息识 别的电源提供方式， 能够灵活的选择输出功能电源， 充分满足先进夹层卡可能 出现的多样化功能电源需求。 进一步的， 软 /硬件识别信号的传输和功能电源 的提供可兼容现有标准接口的定义进行设计， 对现有设备改动小， 容易实现。
