Knowledge of PCI-E card

(1) PCI-e network card: LED indicator
In general, each PCI-E card has a LED (Light Emitting Diode Light Emitting Diode) indicator, used to represent the different state of the network card, to help us to see whether the card is working properly. The typical LED includes Link / Act, Full Power and so on. Link / Act represents that a connection is active, Full represents whether full-duplex, and Power is the power instructions.

(2) PCI-E network card: the main chip
PCI-E network card’s main control chip is a core component of the network card, the performance of a network card is good or bad depend on the chip. PCI-E network card 's main control chip is generally using a 3.3V low-power design, 0.35μm chip technology, which allows it to quickly calculate the data flowing through the network card, to reduce the burden on the CPU.

(3) PCI-E network card: remote wake-up function
Remote Wake Technology (WOL, the Wake-on-LAN) is a network card in conjunction with other hardware and software, a technique of remote boot via the LAN, no matter how far the computer is from us, or in what position, as long as in the same LAN , can be activated at any time. This technique is ideal for environment requiring remote network management. If there is such a request, you should pay attention to whether the network card has this capability.
