Changing the management IP of Huijue fiber optic switch
If the switch supports Layer 2/Layer 3 mode switching, directly configure a management IP address on the service interface after the interface is changed to the Layer 3 mode. Or, assign a static IPv4 or IPv6 address, default gateway, and DNS server with the commands ip address, ipv6 address, ip static. It is shutdown on all network switches. My network is using the IP addresses from the Vlan 410 interface as the management IP. The switch in question is a Cat 3750G configured as a layer 3 switch (IP routing is enabled). This is the core switch in my network. Step 3 Set HyperTerminal parameters: baud rate to 115200, data bit to 8, parity to none, and stop bit to 1. Management IP address configuration on a service interface varies depending on whether a switch supports Layer 2/Layer 3 mode. While making an ICT inventory in an organization I came across a network switch that seems to be locked-down.

Drilling holes in the casing of the construction site s electrical distribution box
Casing drilling systems employ a specialized casing drill bit which is located in front of a DTH hammer, which drills into the ground while simultaneously placing a casing in the hole. In the electric welding processes, flat sheet stock is cut and formed, and the two edges are welded together, without the addition of extraneous metal, to form the desired tube. This is not a drill in the common sense, because it is not. 'Down hole' Casing advance drilling systems (CAS) are a critical part of modern drilling operations, revolutionizing how construction foundations, water wells and Geothermal energy wells are drilled.
