GEI/O控制板DS200SIOBH1ABA具有20個(gè)跳線和3個(gè)開關(guān)塊，每個(gè)塊中有6個(gè)開關(guān)，總共有18個(gè)開關(guān)。它還配有一個(gè)LED和一個(gè)40針連接器。原始板上的GEI/O控制板DS200SIOBH1ABA上的跳線帶有出廠默認(rèn)設(shè)置的跳線。安裝電路板之前，您可以查看印刷材料中的信息，了解跳線的替代設(shè)置以及它們?nèi)绾胃淖冸娐钒宓牟僮饔行┨€只有一個(gè)受支持的位置，因此無(wú)法更改。
當(dāng)您發(fā)現(xiàn)必須更換板時(shí)，最佳做法是將新板上的跳線設(shè)置為與舊板上的跳線位置相匹配。通過(guò)這種方式，板將發(fā)揮相同的作用，并支持驅(qū)動(dòng)器性能。首先，卸下將舊主板固定在主板機(jī)架中的螺釘，然后用雙手將主板從驅(qū)動(dòng)器中取出。小心不要讓主板碰到驅(qū)動(dòng)器中的其他組件。在附近找一人干凈干燥的表面，將靜電保護(hù)袋展平。把舊木板放在袋子上，打開裝有更換板的密封保護(hù)袋，將板滑出。雙手提著，放在舊板子旁邊。將開關(guān)設(shè)置為與舊板上的開關(guān)位置相匹配。

由于光端口采用SFP (small form factor pluggable)收發(fā)器，因此只需要填充所需的端口。VMIACC-5595 SFP光模塊可以是多模(短距離)或單模(長(zhǎng)距離)光模塊的組合。該特性允許在小型網(wǎng)絡(luò)中節(jié)省成本并優(yōu)化系統(tǒng)。對(duì)于較大的網(wǎng)絡(luò)，幾個(gè)VMIACC-5595組件可以級(jí)聯(lián)，允許多256個(gè)節(jié)點(diǎn)的托管集線器陣列。

每個(gè)端口再生串行光信號(hào)，消除了插入損耗和電纜衰減的問(wèn)題。信號(hào)再生也減少了抖動(dòng)。RS232端口提供了通過(guò)簡(jiǎn)單的PC串口監(jiān)控和控制反射存儲(chǔ)器網(wǎng)絡(luò)的能力。以太網(wǎng)端口功能允許用戶通過(guò)局域網(wǎng)(LAN)或Web瀏覽器遠(yuǎn)距離監(jiān)視和控制集線器IS220UCSAH1A 在 QNX 操作系統(tǒng)上運(yùn)行。它有一個(gè) Freescale 8349、667 MHz 處理器。
該板使用的電源額定值為 18-36 V dc，12 瓦。該板可在 0 到 65 攝氏度的溫度范圍內(nèi)使用，并且不需要風(fēng)扇進(jìn)行冷卻，即使在 大額定溫度下也是如此。該板可用于 NFPA 1 類，Div。2個(gè)應(yīng)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.
