DS200SIOBH1ABA

GEI/O控制板DS200SIOBH1ABA具有20个跳线和3个开关块，每个块中有6个开关，总共有18个开关。它还配有一个LED和一个40针连接器。原始板上的GEI/O控制板DS200SIOBH1ABA上的跳线带有出厂默认设置的跳线。安装电路板之前，您可以查看印刷材料中的信息，了解跳线的替代设置以及它们如何改变电路板的操作有些跳线只有一个受支持的位置，因此无法更改。
当您发现必须更换板时，最佳做法是将新板上的跳线设置为与旧板上的跳线位置相匹配。通过这种方式，板将发挥相同的作用，并支持驱动器性能。首先，卸下将旧主板固定在主板机架中的螺钉，然后用双手将主板从驱动器中取出。小心不要让主板碰到驱动器中的其他组件。在附近找一人干净干燥的表面，将静电保护袋展平。把旧木板放在袋子上，打开装有更换板的密封保护袋，将板滑出。双手提着，放在旧板子旁边。将开关设置为与旧板上的开关位置相匹配。

由于光端口采用SFP (small form factor pluggable)收发器，因此只需要填充所需的端口。VMIACC-5595 SFP光模块可以是多模(短距离)或单模(长距离)光模块的组合。该特性允许在小型网络中节省成本并优化系统。对于较大的网络，几个VMIACC-5595组件可以级联，允许多256个节点的托管集线器阵列。

每个端口再生串行光信号，消除了插入损耗和电缆衰减的问题。信号再生也减少了抖动。RS232端口提供了通过简单的PC串口监控和控制反射存储器网络的能力。以太网端口功能允许用户通过局域网(LAN)或Web浏览器远距离监视和控制集线器IS220UCSAH1A 在 QNX 操作系统上运行。它有一个 Freescale 8349、667 MHz 处理器。
该板使用的电源额定值为 18-36 V dc，12 瓦。该板可在 0 到 65 摄氏度的温度范围内使用，并且不需要风扇进行冷却，即使在 大额定温度下也是如此。该板可用于 NFPA 1 类，Div。2个应用程序。

The GEI/O control board DS200SIOBH1ABA has 20 jumpers and 3 switch blocks with 6 switches in each block for a total of 18 switches. It also comes with an LED and a 40-pin connector. The jumpers on the GEI/O control board DS200SIOBH1ABA on the original board come with a factory default set of jumpers. Before installing the board, you can review the information in the printed material to learn about alternative Settings for jumpers and how they change the operation of the board. Some jumpers have only one supported location and therefore cannot be changed.
When you find that you must replace the board, the best practice is to set the jumper on the new board to match the jumper position on the old board. In this way, the board will play the same role and support drive performance. First, remove the screws that hold the old motherboard in the motherboard rack, and then remove the motherboard from the drive with both hands. Be careful not to let the motherboard touch other components in the drive. Find a clean, dry surface nearby and flatten the bag. Place the old board on the bag, open the airtight protective bag containing the replacement board, and slide the board out. Take it in both hands and put it next to the old board. Set the switch to match the switch position on the old board.
Since optical ports use small form factor pluggable (SFP) transceivers, only the required ports need to be filled. The VMIAC-5595 SFP optical module can be a combination of multi-mode (short distance) or single-mode (long distance) optical modules. This feature allows for cost savings and system optimization in small networks. For larger networks, several VMIAC-5595 components can be cascaded to allow an array of more than 256 nodes of managed hubs.

Each port regenerates the serial optical signal, eliminating insertion losses and cable attenuation. Signal regeneration also reduces jitter. The RS232 port provides the ability to monitor and control reflective memory networks via a simple PC serial port. The Ethernet port feature allows users to remotely monitor and control the hub IS220UCSAH1A running on the QNX operating system via a local area network (LAN) or Web browser. It has a Freescale 8349, 667 MHz processor.
The board uses a power supply rated 18-36 V dc, 12 watts. The board can be used in a temperature range of 0 to 65 degrees Celsius and does not require a fan for cooling, even at large temperature ratings. The board is available for NFPA 1 class, Div. 2 applications.
