GCM16和GCM32全球控制管理器产品指南说明书

GCM16 and GCM32 Global Console ManagersProduct GuideThe Global 2X2X16 Console Manager (GCM16) and Global 4X2X32 Console Manager (GCM32) are the next generation digital keyboard-video-mouse (KVM) console managers that provide KVM-over-IP and serial console management technology in a single appliance. Either console lets you access and manage all servers remotely, even to the system BIOS, using your existing IP infrastructure.The GCM16 has 16 target ports and supports up to 2 local users and 2 remote users, and the GCM32 has 32 target ports and supports up to 2 local users and 4 remote users. Figure 1 shows these two models.Figure 1. The Global Console Managers: GCM16 (top) and GCM32 (bottom)Did you know?The GCM16 and GCM32 Global Console Managers provide enhanced remote management, access, and security capabilities with out-of-band access to servers, network equipment, and other devices with serial configuration or console ports all from a single appliance. This unified approach improves staff efficiency by reducing the time required to remotely diagnose, reconfigure, repair, or restore servers as well as network devices and other hardware with serial configuration or management consoles, or both.The serial capabilities of these appliances enable connecting and managing nearly any device with a serial port directly from the console manager, including switches, routers, and PDUs. SSH and Telnet connections are supported.Click here to check for updatesFeature comparisonThe GCM16 and GCM32 replace the GCM2 Global Console Manager. Table 2 compares the console switches.Table 2.

The GCM16 Global Console Manager has identical connections except it only has 16 ARI ports, whereas the GCM32 has 32 ARI ports.Figure 2. Connections on the GCM32 Global Console ManagerNote: Figure 2 shows the rear of the unit. There are no connectors on the front of the unit.FeaturesDetails about the features of the GCM16 and GCM32 are as follows:Number of local concurrent users:The GCM16 and GCM32 console switches enable one or two local user to access any attached servers. If the target device is currently in use, the user attempting to gain access will be given an opportunity to force a connection to the device if their preemption level is equal to or higher than the current user’s level. If the user attempting to gain access has a lower preemption level, the active user will be asked if they wish to give up control to the new user (a timeout is also configurable).The GCM16 and GCM32 both support two independent local users as shown in Figure 3. One local user attaches to the VGA and USB ports on the console switch as shown in Figure 2. The second local user attaches to a tiered (slave) console switch (see "Tiered consoles" below for more information). These two ports are independent of one another (that is, not pre-emptive or shared). This configuration allows you to place a console in every rack, for local connectivity to those servers complete with local KVM access, plus tier up to a master console that has local KVM access to all the servers attached to all attached console switches.Figure 3. Two local users in a tiered configurationLocal user connections:Local displays are connected to the console switch using VGA analog connections. Keyboard and mouse must be USB attached and two USB ports are provided for this purpose. Two additional USB ports are provided for the attachment of devices such as optical drives or memory keys. These devices can be made available on remote target systems provided Virtual Media Conversion Options are used to connect to those target systems. Note, however, that the Virtual Media Conversion Option does not support chaining of target systems.Target systems:The GCM16 has 16 target system ports (known as analog rack interface or ARI ports) and the GCM32 has 32 target system ports. These can be directly attached to systems with the appropriate USB or PS/2 conversion option connector on the end. These connections use standard CAT-5 cables. You can increase the number of connected target systems by two methods: chaining or a tiered arrangement of switches (more about these below). Both methods mean that each of the 16 or 32 ports will have multiple systems connected to it. You can mix connection methods.Remote access via Ethernet or Modem:Remote access to console switch and to the target systems is via a Web browser. The switch provides agentless remote control and access. No special software or drivers are required on the attached servers or client. Access is normally via a standard Ethernet network, requiring that the console switch be connected to the network via one or both Ethernet ports. Connecting both ports provides redundancy. Additionally, if a modem is connected to the modem port on the console switch and the modem is connected to a telephone (PSTN) system, then you can dial the console switch via your modem and establish an out-of-band connection to the console switch using the Point-to-Point Protocol (PPP) for remote control. V.34, V.90, or V.92 connections are supported.Conversion Options:These are cable-connector combinations that are connected between the CAT-5 cables from the console switches to the target systems. The figure below shows the conversion option cables that can be used with the console switches. The part numbers are listed in the Part number information section.The Virtual Media Conversion Options (VCO and VCO2) supports the virtual media capability of the console switches; however, they do not support chaining.Note: The KVM and USB conversion options are withdrawn from marketing.Figure 4. Available conversion optionsThe built-in memory of each connection option helps simplify configuration by assigning and retaining unique server identification codes for each attached server. This integrated intelligence enhances security and helps prevent unauthorized access to a server through cable manipulation. The connection option is powered directly from the server, providing Keep Alive functionality even if the server is not powered on. Supported video resolutions are listed in the following table.The GCM16 and GCM32 switches also allow you to use smart cards to ensure access is authorized. Smart cards are pocket-sized cards that store and process information. Smart cards such as the Common Access Card (CAC) can be used to store identification and authentication to enable access to computers, networks, and secure rooms or buildings. Smart card readers are connected directly to the switch via one of the USB ports, or they can be connected to any remote workstation that is running the remote browser interface or DSView management software and is connected to the switch using an Ethernet connection.Note: For smart card use, the target device must be connected to the console switch using the Virtual Media Conversion Option Gen2 (VCO2), part number 46M5383.Use of encryption:The GCM16 and GCM32 support encryption for KVM signals and for remote media. Available encryption levels are 128-bit SSL, DES, 3DES, or AES. These are configurable via the browser interface.True serial capabilities:The GCM16 and GCM32 switches support Serial Conversion Option (SCO) cables that provide serial capabilities through Telnet. The capability provides a proper serial connection, not serial-to-VGA conversion. You can launch an SSH session or a serial client from the on-board Web interface to connect the targets that are connected to the GCM16 and GCM32 switches with an SCO cable. The SCO includes a separate USB-to-barrel power cord adapter - see Figure 2. Connect the USB end of the adapter to an available USB port on the target system to supply power to the SCO.Managing Intelligent Power Distribution Units:The dedicated Power Distribution Unit (PDU) ports on the GCM16 and GCM32 switches support the direct attachment of certain Avocent-branded Intelligent PDUs and can provide the ability to view and manage these units directly through the switch. Lenovo Intelligent PDUs are not supported.Tiered consolesTiered consolesYou can tier multiple rack console switches to enable access to additional servers. In a tiered system, an ARI port on the main rack console switch connects to the ACI port of a tiered rack console switch (see Figure 3 for locations of these ports). Consider a tiered configuration if you want to manage servers connected to multiple switches from one central location. For example, you could have a primary GCM16 console switch with 16 switches tiered underneath it that all have servers chained on their ports.The GCM16 and GCM32 support two levels of tiering. The use of virtual media and smart card authentication are both supported only when primary and secondary switches are GCM16 or GCM32 console switches.Figure 6 shows an example of tiered consoles.Figure 5. Tiered consolesIf there are local users attached to other tiered consoles, each can control target systems connected to that specific console. The local user at the primary console (Local user A in Figure 6) can preempt other local users if necessary.The GCM16 and GCM32 support up to 1024 target systems in a tiered configuration.Physical specificationsTrademarksLenovo and the Lenovo logo are trademarks or registered trademarks of Lenovo in the United States, other countries, or both.

发电机状态监视系统(GCM)说明书一工作原理发电机状态监测器(GCM)包括一个离子室检测器(ICD)、电表/报警盘、记录器、流量计(差压表)、过滤器/电磁阀及流量设定阀。
它是设计用于氢气压力高达100PS1G(磅/平方英寸表压)(7巴)的。
从发电机来的氢气经过过滤器电磁阀组件、ICD及流量设定阀。
该ICD产生一个由电位计放大并施加在记录器或盘式表上的电流。
在正常运行情况下,该输出电流是一个由流量及氢气压力而决定的定值。
当有颗粒、例如由于超温而产生的颗粒存在时,此电流将下降,控制回路将打开一个触点,琥珀色的安全灯将熄灭,而红色的报警灯将点亮。
用于外部报警的SPDT(单极双投)接触也被触发。
一旦该回路报警了,它可以通过按在电表/报警盘上的“ALARM SEQUENCE RESET”按钮而被重新设定。
该报警是有故障保护的,并将在电源发生故障的情况下触动SPDT外部报警触点。
通过ICD的正确的流量是由位于ICD出口侧上的柜内侧的流量设定控制装置设定的,而在电表/报警盘上的报警设定控制则设定报警跳闸点。
在正常运行情况下,在过滤器/电磁阀组合中的过滤器是被旁路掉的。
当前面板上的“FILTE”按钮被按下时,该电磁阀被启动,全部气体通过过滤器而除去颗粒。
其目的是为了确定一个报警状态是真实的或者是设备故障的结果。
假如报警是真实的,并确有颗粒存在于气流中,按下“FILTE”按钮将导致输出电流返回至正常、安全的水平。
当该按钮被按下后,红色的FILTE灯应亮着。
GCM所有的组件均放置在一个单独的小室中。
对所有型号均配备有一个试验颗粒源。
当按下一个按钮而启动该源时,颗粒被引入ICD;通过生成一个模拟的报警信号校核其运行。
GCM配备有一个集成的自动采样器。
当GCM发警报时,氢气通过一个可移动的收集器,它捕捉了由热力分解产生的颗粒。
然后该收集器可以被送到试验室,以分析过热的来源。
GCM可以与通常位于控制室内的GCM自动报警装置相连接。
该自动报警器监测GCM 的输出并将其显示于一个表计或记录器上。
当输出下降时,该过滤器自动地插入;该自动报警器决定了是否有一个GCM故障存在,或验证报警状态存在。
该自动报警器控制自动采样器,仅在为了证实一个报警时才启动它。
假如GCM输出超过了预设定的上限或下限,或者GCM流量降至设定极限以下,该自动报警器就提供警告指示。
二试验颗粒源在电位计/报警盘上的“PARTICLE TEST”按钮开关启动试验颗粒源。
一个红色的导向灯“VERIFIED ALARM”(检验报警)表示该源已启动。
颗粒由在试验源中的加热线上的涂层所产生,它包含着用于50次或更多次试验的足够的材料。
该源应仅在氢气纯度及压力适于发电机正常运行、且GCM在“安全”模式时才被启动。
触动该“PARTICLE TEST”按钮应将使输出电流在约5秒钟之内产生一个明显的下降。
一旦GCM有了报警,该颗粒源的电源将被自动断掉。
假如保持“试验”按钮被按下20秒钟之后仍无反应,则需更换试验颗粒源。
通过按下“FILTE”及“PARTICLE TEST”按钮,核查过滤器及电磁阀。
输出电流不应发生变化且无报警。
切勿将“PARTICLE TEST”按钮保持按下超过20秒,并且应在释放“FILTE”按钮之前先释放它。
三报警步骤1.无自动报警如果有一个报警指示,需检查记录图表。
假如报警是由于过热,记录的电流迹线应显示电流在几分钟或小时内会有一个逐渐的下降。
假如电流下降并立即恢复至正常水平,该报警很可能是瞬间电力中断的结果;在此情况下,应通过按下“重置”按钮重新设定该报警。
假如确实显示电流有一个确定的、持久的下降,并且“流量”读数是正常的,按下“过滤器”按钮。
(在流量显示上有一个大于20%的下降,表示在电磁阀或过滤器中有过量的限制,对此应加以调查)。
输出电流应返回至接近其正常值。
假如确实如此,则该下降是铁芯故障或是其它颗粒源譬如发电机中过热导致的,应采取恰当的措施。
假如在“过滤器”按钮按下的情况下,电流仍维持在报警水平以下,则表示GCM的某一个组件有故障,这可使用“故障寻找”中概述的程序确定其位。
当“自动采样器”系统被启动了,通过GCM入口的流量增加,ICD的流量可能减少。
对于风机差压低的发电机这个效应将达到最大,尤其是当入口管很长时。
在有些情况下,ICD流量可能为零。
由于这个原因,可能有必要等待,直至“自动采样器”流量已在进行上述报警验证程序之前被关闭。
2.有自动报警该“自动报警”自动地确定是“GCM故障”引起了GCM输出的下降,还是由于发电机过热引起了“证实的报警”,从而可以采取适当的纠正动作。
因为“自动采样器”仅在一个报警已由“自动报警”证实之后才被启动的,任何从“自动采样器”来的ICD流量的变化,在“自动报警”被使用时,将不会影响报警的证实。
四自动采样器“自动采样器”的操作是自动的,毋需另外的注意。
假如不需要自动运行并且未安装有“自动报警”,则在TB2上的端子7及8之间的连接应该被去掉。
假如安装了“自动报警”,则扭开在报警屏上的“MANUAL START ONL Y”指示器,即可禁止“自动采样器”的自动操作。
如果到GCM的交流电先被断开然后恢复,虽然“报警”灯可能亮着,但该采样器将不会被启动。
通过按下采样器控制上的“START”按钮,在任何时候都能收集样品。
在预先设定的时间间隔之后,该流量将被自动地停止。
该流量的停止可先于按下采样器上的“停止”按钮。
五定期检查和维修为了确保GCM的连续可靠的性能,建议进行下列的定期检查:每天:1.检查流量,“FLOW”上指示应为1.5;如有必要,用“流量设定”控制设定为正常。
2.检查输出电流轨迹,它应在记录器或表计上的箭头处(显示)。
每周:按下“过滤器”按钮,指示器灯应亮,假如电磁阀在工作,应有一个可听到的滴答声。
流量或输出中应无变化或仅少量变化。
假如流量指示值下降超过20%,过滤器可能受限制了。
假如输出显著地增加,可能有一些颗粒存在于氢气中。
每月:启动“试验颗粒源”。
在发电机停机期间,建议维持给GCM供电,特别是在高湿度时期。
其目的是避免水分冷凝在ICD及电位计/报警中的关键绝缘器上。
假如安装了记录器,可将其电源停下,以停止图表驱动。
六详细说明1.离子室检测器(ICD)ICD包括一个离子化区及一个离子收集室,均包含在一个压力外壳内。
气体首先通过离子化去,它包含一个低能级的α源(钍232)。
然后产生的离子和气体一起传送至离子收集室,在那里有一个电极维持在对地-1 0伏。
由于离子非常小,它们对质量有一个高比例的电荷,将其放在一个电气场中,它们有一个高的活动性。
10伏的电势是足够引起大部分离子被吸引至收集电极上;在该处,它们产生的电流由电位计指示。
当气体中存在有颗粒时,某些离子将吸附着他们。
这些颗粒,即使在显微镜下也看不清,也比离子大了许多倍。
因此,颗粒—离子组合的电荷与质量的比减少了许多(千分之一左右),故其可动性低。
这意味着现在仅少数被吸引至收集电极,导致至放大器的电流减少。
试验显示:当一个面积大约为13平方厘米的芯材,在一个典型的发电机内侧,被足够地加热到使珐琅涂层退色时,电流将减少50%。
在正常的发电机运行下,在氢气中的颗粒浓度基本为零。
图5显示:当“流量”计的设定维持在1.5,纯氢的典型的离子室输出电流及体积流与压力的函数关系,它显示在一个已知的设定值下,电流依赖于氢气压力;压力增加电流就减少。
但是,假如当压力变化时不重新调整流量,此效应将被部分地抵消;压力的增加导致发电机的一个较高的风扇差压,从而增加了流量,这将减少电流的变化(流量减小,输出电流下降)。
所绘的是体积流量(而不是惯常的标准流量),因为它更逼真地确定离子室性能。
该电流曲线在约2巴处有一个峰值;体积流率降低引起压力增加,电流就减少。
当压力降低至2巴以下时,电流再次下降;这是因为较低的气体密度允许一些α颗粒在它们产生离子之前到达离子室的壁上。
2.电位计/报警回路只要GCM输出高于报警水平,它将置继电器K2于安全模式中。
当GCM输出下跌至50%以下时,置K2于报警模式。
从而即使GCM输出上升至50%以上,输出触点将留在报警模式,直至按下“重置”(RESET)按钮。
在流量计中一个磁性操动的簧片开关控制流量报警回路。
在正常流量时,该开关闭合并短路了电路板B3上的固态继电器K1的输入端子。
在低流量时,该开关打开,它使K1通电,并施加交流线电压至“自动报警”中的流量报警回路。
该流量报警开关在工厂中已调整好在流量减少约20%时打开。
由于流量压差与流量的平方成比例,这相当于一个流量指示减少约36%。
3.自动采样器假如未安装“自动报警”,任何时候GCM由“安全”变成“报警”状态,采样器将启动,一股气体流将在一个规定的时间内经过收集器,此时流量将被关闭。
一个盖子联锁装置可避免当校核电位计零位或使用“试验颗粒源”时自动启动采样器。
该流量能在任何时候用手启动或停止。
当安装有“自动报警”时,继电器K3被更换。
但是一个适配器将传送“自动采样器”控制于“自动报警”屏,因此采样器只有在一个报警被证实时,才被启动。
七故障查寻由于没有移动部件、高温组件或危险的调整,GCM应长期无故障地工作。
如果有任何运行困难,要核查电源及所有连接处。
1.回路保护GCM回路由一个位于电位计/报警盘上的5安培断路器保护。
跳闸时其按钮将伸出,并可见一个红光带。
在确定并纠正了跳闸原因后,压下按钮以重新置位。
2.无流量指示并无输出电流●阀门被关闭,或至发电机的管道有堵塞。
●至发电机的不正确的连接导致零或低的差压。
3.负流量指示●至发电机的连线接反了。
●流量计有故障。
4.不稳定的流量●在通往发电机的管道中、或GCM的管道中有液体进入。
●“流量设定阀”中有污物。
5.流量良好,但输出电流低或无。
●到ICD的-10伏连接开路或短路了。
●电位计坏了。
●至电位计的电缆开路、连接被断开,或短路了。
●表计或记录器坏了。
●电源坏了。
●ICD中输出对地短路。
6.输出电流超限,甚至在流量为零或流量低时也超限●可能由于离子室中进入了纤维,造成短路、或ICD内有导电通路。
●供电有故障。
●电位计有缺陷。
●R1开路,或在反馈回路中开路,或R5开路。
7.输出良好,但报警不重置●A2或B2组件有缺陷。
●K1有缺陷。
●K2有缺陷。
●R6或相连的接线有缺陷。
●S2有缺陷,核查“遥控重置”。
8.输出低于50%但回路不报警●R6(报警设定)有缺陷或未恰当地调整●A2或B2组件有缺陷●K1有缺陷●K2有缺陷●S2短路,或在“遥控重置”回路中有短路。
9.过滤器灯持续亮着●S3有缺陷。
由于输入信号可能被过滤器去掉,在此情况下GCM将不会探知一个故障。
为了临时操作,可通过断开电磁线圈回路中的2针连接器(J4),对电磁线圈断电。
