sgmii sfp

Recently debugged the lattice Sgmii interface. The initial schema for the project is probably the same, for debugging.The architecture on this side of the FPGA is tri_mac to sgmii and then out of PCs. In fact, Sgmii nuclear comes with a PCs core, the most deceptive is that PCs must be external clocks, and finally there is no way to generate only a PCs core and

What are the advantages of a small pluggable (SFP) port for a Gigabit Ethernet switch? How do I connect the four SFP ports of a d-link DGS 1248 t smart switch? I think the main advantage of the SFP port is the flexibility to connect to the network. The SFP port is a hot-swappable input/output device that can be plugg

These days, when HP acquired H3C, it was rare to see 3COM with 3 O-markers. But the problem, a year ago a project bought a 3COM switch 2924-SFP plus switch (PS: pure switch, no readable data). At that time saw a default management IP in the back, so log in to the Web interface configuration can be. Later the project bought H3C S5500 switch, do not have this switch, so idle.Due to the recent equipment is more tense, need to enable, the problem came, bu

The SFP is the abbreviation for the small FORM pluggable and can be easily understood as an upgraded version of the Gbic. The SFP module is half the size of the Gbic module, and can be configured with more than one port number on the same panel. The other features of the SFP module are basic and gbic consistent. Some switch vendors call the

How to disable the SFP module on H3C vswitches and other devices? The following warning is displayed: OPTMOD/4/PHONY_MODULE: GigabitEthernet1/0/2: This transceiver is NOT sold by H3C. h3C therefore shall NOT guarantee the normal function of the device or assume the maintenance responsibility thereof! This is a warning when SFP module is used on H3C vswitches, routers, and other devices. It generally means t

1. What is GBIC? GBIC is short for Giga Bitrate Interface Converter. It is an Interface device that converts Gigabit electrical signals into optical signals. GBIC is designed for hot swapping. GBIC is an Interchangeable product that complies with international standards. The gigabit switches designed with GBIC interfaces share a large market share due to flexible exchange. 2. What is SFP?

the port specification when purchasing the device. You only need to select the GBIC corresponding to the required transmission interface, and it is easy to make adjustments as needed. The current GBIC has a Small version (Small Form-factor Pluggable, SFP), also known as mini GBIC (mini GBIC ), The size is about half of the original size, which not only saves costs, but also doubles the port density of network devices. Term 3 Small encapsula

, what's more, the installer simply overwrites the system files of the new and old versions (many games and irresponsible applications do this ).What are the consequences of overwriting system files? It is hard to say that if you are lucky enough, you may not have any problems. But in most cases, it is to make your system unstable or crash at some specific time. In this case, Microsoft engineers use the DLL Hell-the Windows system uses the Dynamic Link Library (Dynamic Link Library) to share all

is an integer representing a specific signal. We ignore it temporarily. The previously assumed function body defines the sigfunc function. Therefore, the declaration of the sigfunc function can be as follows: Void sigfunc (INT ); Now, if we want to declare a pointer variable pointing to the sigfunc function, we may name it SFP. Therefore, SFP points to the sigfunc function. *
