What is a backplane assembly

A backplane (or “backplane system”) is a group of electrical connectors in parallel with each other, so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a computer bus

What does a backplane do?

A backplane is the circuitry that provides connectivity between the different modules on a switching or routing device. … For network monitoring and management, backplane capacity (or backplane bandwidth) is a very important concept. Backplane capacity acts as a cap on the maximum throughput of a network device.

What is backplane in chassis?

A backplane is similar to a personal computer’s motherboard and sometimes a term improperly used to describe the computer’s motherboard. The backplane is a printed circuit board containing connections (slots) for expansion boards and allows for communication between all connected boards.

What does backplane mean in computers?

A backplane is an electronic circuit board containing circuitry and sockets into which additional electronic devices on other circuit boards or cards can be plugged; in a computer, generally synonymous with or part of the motherboard.

What is a backplane PCB?

Definition. The term Backplane PCB generally refers to larger format printed circuit boards that are used as backbones for connecting several PCBs together to ultimately form a computer bus. Typically, they do not contain active components; rather, they serve as a connection center between active duty PCBs.

What is a backplane switch?

As explained, backplane is a circuit biard that connects several connectors in parallel to each other. Switch backplane generally refers to the switch fabric. When we talk about the switch backplane capacity, this refers to the maximum throughput when the switch is fully in use.

What is the backplane on a server?

Basically, a backplane is a board (also known as a PCB or printed circuit board) with a bunch of connectors (or slots) that allows a server to access multiple drives.

What are backplane connectors used for?

Often referred to simply as a backplane, this special type of printed circuit board is used as a support structure for connecting other PCBs. The backplane connector adds mechanical strength and stability while also acting as a plane for integrating other system components called daughterboards.

Is a backplane a motherboard?

A backplane is generally differentiated from a motherboard by the lack of on-board processing and storage elements. A backplane uses plug-in cards for storage and processing.

What is a PCIe backplane?

Designed to provide the most PCIe slots on the market while battling the harshest conditions. Each PCIe backplane is built to operate at peak performance on sea, land, air, or space across mission-critical applications and programs worldwide.

What is power supply backplane?

The power supply backplane carries 12V power from the power supplies to the power distribution board over a pair of bus bars. It also delivers 3.3V standby power over a three-pin wire cable. Caution – The system supplies standby power to the power distribution board even when the server is powered off.

What is the backplane in LCD?

Explanation: The ac voltage applied between the segment and a common element is called the backplane(bp). In which each segment is driven by an EX-OR gate.

What is line card in Cisco router?

The MSC, FP, and LSP card, also called line cards, are the Layer 3 forwarding engine in the Cisco CRS 8-slot Line Card Chassis Enhanced router. … A line card can be paired with different types of PLIMs to provide a variety of packet interfaces, such as OC-192 POS and OC-48 POS.

What is a passive backplane?

Passive and Active Although resistors may be used, a “passive” backplane adds no processing in the circuit. An “active” or “intelligent” backplane may have microprocessor or controller-driven circuitry that adds a little or a whole lot of processing.

What is a midplane?

Definition of midplane : a plane passing through something in such a way as to divide it into symmetrical halves.

What is backplane speed?

Backplane bandwidth is a measure of the bandwidth of the internal architecture of the switch. The term is thrown around pretty loosely to refer to anything internal to the switch that doesn’t refer directly to the packet forwarding rate of the forwarding engine. The Backplane speed depends on the type of switch. (

What is OIR in Cisco?

Online insertion and removal (OIR) enables you to replace faulty modules without affecting system operation, which is similar to hot-swapping. OIR commands are issued before removing a module and after installing a module. When performing OIR, an identical module must be used to replace the original one.

What is backplane bandwidth?

The backplane bandwidth of the switch is the maximum amount of data that can be throughput between the switch interface processor or the interface card and bus. The backplane bandwidth marks the total data exchange capability of the switch, and the unit is Gbps, also called the exchange bandwidth.

What are the two categories of SBC?

Single board computers are now commonly defined across two distinct architectures: no slots and slot support. Embedded SBCs are units providing all the required I/O with no provision for plug-in cards.

What are PCIe expansion cards?

The term “PCIe card” and “expansion card” simply refers to hardware, like graphics cards, CPUs, solid-state drives (SSDs), or HDDs, you may add to your device through PCIe slots, making both catch-all terms for a variety of components.

Which statement best describes the purpose of a math co processor?

The math co-processor performs all of the logic functions on behalf of the processor.

What is liquid crystal state?

Liquid crystals (LCs) are a state of matter which has properties between those of conventional liquids and those of solid crystals. For instance, a liquid crystal may flow like a liquid, but its molecules may be oriented in a crystal-like way.

What is an LCD controller?

The LCD controller is a small microprocessor that converts the customer’s software code (aka firmware) to information that the LCD can understand. The LCD screen then displays graphics, characters, images and numbers to be seen by the end user. … This allows the customers product to monitor the LCD.

What is the purpose of a line card?

A printed circuit board that provides a transmitting/receiving port for a local area network (LAN) or a carrier’s telephone or wide area network (WAN). Line cards plug into telephone company switches and high-end routers, which have a modular chassis that accepts a range of cards.

How many ports does a line card have?

Each physical interface controller can support up to four physical ports and there can be up to four physical interface controllers on a PLIM.

What is a digital line card?

A line card or digital line card is a modular electronic circuit designed to fit on a separate printed circuit board (PCB) and interface with a telecommunications access network. … A line card can terminate a line supporting voice POTS service, ISDN service, DSL service, or proprietary ones.
