Hardware required for the Remote Wake-up function of the computer

When the internet cafe network administrator wants to remotely manage and use the main client of the Internet cafe, the Remote Wake-up technology of the computer is required, that is, Remote Boot through the LAN. In this way, no matter how far the accessed computer is from us, it can be started as long as it is in the same LAN.

This article briefly describes the hardware requirements of computers for the Remote Wake-up function.

Computers that can be remotely woken up have certain hardware requirements, mainly manifested in the NIC, motherboard, and electrical source.

1. Motherboard

The motherboard must also support remote wakeup. You can check whether the "WakeonLAN" item exists in the "PowerManagementSetup" menu of CMOS. In addition, the motherboard that supports remote wakeup usually has a dedicated 3-core socket to power the NIC (PCI2.1 standard ).

Because the current motherboard usually supports the PCI2.2 standard, you can directly provide the network adapter with the + 3.3VStandby power supply through the PCI slot, even if you do not connect to the WOL power cord, you can also achieve remote wakeup. Therefore, A 3-core socket may no longer be provided. Whether the motherboard supports the PCI2.2 standard. You can check whether the "WakeonPCICard" item exists in the "PowerManagementSetup" menu of CMOS.

2. Nic

Whether Remote Wake-up is possible. One of the most important components is the network card that supports WOL. My company's TF-3239 supports WOL. The NIC of the Remote Wake-up computer must support WOL, but the NIC used to wake up other computers does not support WOL. In addition, when multiple NICs are installed in a computer, only one of them is set as Remote Wake-Up.

3. Power supply

To achieve remote wakeup, the computer must be installed with ATX power supplies that comply with the ATX2.01 standard, and the + 5VStandby current should be at least 600mA.

The above are the hardware required for the Remote Wake-up function of the Internet cafe computer, and hope to help you.
