IS200VCMIH2BEE是一款雙面板。電路板的背面主要是電阻和電容。電路板的正面更復(fù)雜，包括連接器端口(包括兩個(gè)背板)、電感/扼流圈、tp測(cè)試點(diǎn)和集成電路。連接的前面板有三個(gè)IONet端口和一個(gè)陽串行端口。它有一個(gè)復(fù)位按鈕、兩個(gè)固定螺釘和四組LED指示燈(一組3個(gè)、一組6個(gè)、一組8個(gè)和另一組3個(gè))。)面板上還標(biāo)有公司標(biāo)志和板號(hào)。

IS200VCMIH2BEE

The IS200VCMIH2BEE is part of the Unit Data Highway (UDH). It functions as the main communication control board. The data is read and transmitted to other boards via Fiber Optic Ethernet (IONet).
VCMI boards can be designed for simplex or TMR(three-mode redundancy) applications. The simplex board has one IONet port, while the TMR board has three. The IS200VCMIH2BEE board is a TMR board.
IS200VCMIH2BEE uses SIFT voting (software-implemented fault tolerance.) The data is broadcast as a packet to all remote racks. VCMI boards at these remote locations extract the appropriate packet data.
The IS200VCMIH2BEE is a dual panel. The back of the circuit board is mainly resistance and capacitance. The front of the board is more complex and includes connector ports (including two backplanes), inductors/chokes, tp test points, and integrated circuits. The connected front panel has three IONet ports and one positive serial port. It has a reset button, two setting screws, and four sets of LED indicators (one set of three, one set of six, one set of eight, and another set of three). The panel is also marked with the company logo and board number.
