每个OMNIBUS A12提供十二个PCI扩展插槽。可以用于插入UGX显示卡、OMNISCALER、四模拟视频卡、流视频卡、双RGB输入卡与四SDI视频卡等。

    尽管OMNIBUS A12的底板基于标准64位 / 66MHz PCI总线，强烈推荐不要插入上述卡之外的其它卡。由于无驱动程序支持，其它卡将无法工作，同时还存在OMNIBUS A12或者插入卡损坏的风险。

    在OMNIBUS A12前活门后面的最下面位置，有一个电源开启 / 关闭开关。最上面则是蜂鸣器复位按钮，用来确认冗余电源模块故障。在这两个按钮之间，有两个LED；左边的绿色电源开启LED指示电源是否开启。右边的红色待机 / 组件故障LED指示冗余电源模块无法运行。

  Each OMNIBUS A12 provides 12 PCI extension slots. Can be used to insert UGX display card, OMNISCALER, four analog video card, stream video card, double RGB input card and four SDI video card.

   Although the base plate of OMNIBUS A12 is based on the standard 64-bit / 66 MHz PCI bus, it is highly recommended not to insert cards other than those mentioned above. Other cards will not work without driver support, and there is also a risk of damage to the OMNIBUS A12 or the insert card.

   At the bottom of the OMNIBUS A12 rear trap, there is a power on / off switch. Above is the buzzer reset button to confirm the redundant power module failure. Between these two buttons, there are two LEDs; Turn on the green power source on the left. Red standby on the right / component fault LED indicates redundant power module can not run.
