8 port infiniband switch

Ordinary computers do not have a generic input outlet (GPIO), but sometimes I would like to enter a switch quantity. For example, let the user pull the pull rope switch to start an application, such as a contact switch to determine whether the door is open or closed, such as .... Demand is so simple, you are not willing to spend dozens of yuan to buy a single c

Demonstration of port aggregation configuration and troubleshooting of Huawei switch s5700Huawei port aggregation is divided into two types: manual Load Balancing eth-trunk link and LACP eth-trunk link. I will only introduce the former here. The manual eth-trunk can be regarded as an interface, which can be access or trunk. After creation, the configuration is ex

printer can be modified. The higher the baud rate, the faster the transmission speed. If the printer has a dial switch, you can adjust the 7th or 8 bit switch to adjust the baud rate, if you do not have the dial switch, you can download the setting tool on the official website of Jiabo to modify the print baud rate.

Solution to the error "err-disable" on the switch port Instance: We pulled an MSTP line from the customer's IDC room. After connecting to the Cisco 3750x, the port lights will not light up, and the port will not light up after it is changed, the error "err-disable" is reported because the client has a loop. Fault sympt

How did we find out that Serv_u occupies IIS 80 ports, and we can refer to this article in the cloud-dwelling community. IIS Another program is using this file and the process cannot be accessed. How do I see which program has the TCP 80 port open? Use the Open port view software active ports to make it clear at a glance. The following are the specific solutions: Serv_u Version 6: You can set the next PAS
