When a prack is received, a match is needed, and if matched, the retransmission clock can be aborted. The so-called match refers to the Prack and the temporary response in the same session, and rack in the method, cseq-num,response-num in this pair of messages are consistent. The so

(1) Wiring color identification management method, suitable for the integrated wiring System project scale is small, the user information point quantity is not many, the network structure is simple and is dispersed, only a few main lines or a few floor wiring frame, usually uses the color marking management plan. (2) Wiring Intelligent management mode, apply to the integrated wiring syst

special and timely posters, to give the brother a praise?Asset Management functionsThe above are some small changes in the interface, the following for everyone on a few hard dishes.Rack free SpaceWhen the server is on the shelves, it will occupy and separate the space of the cabinet. It is a very important daily work to understand the occupancy of each rack and the size of free space in the whole machine room. The 3d is the right place to look: We h

and manufactured for Internet cafes, small and medium-sized enterprises, and schools. It has the most outstanding features, outstanding stability, outstanding throughput and strong load capabilities, rich and easy-to-use features. It supports CABLE/xdsl modem access, or Ethernet access. Provides four 10/100 Mbps LAN ports and one 10/100 Mbps WAN port. The WAN port can be connected to xDSL, Cable Modem, leased line, LAN, and so on. It supports DDNS, DHCP server, and network address translation N

dedicated tool to install other parts of the module in place.5. According to the configuration of the manufacturer, the shielding layer of the module can be reliably connected to the copper foil, and the whole shielding part of the module can be reliably installed in place.6. to avoid the impact of bending torque caused by cable laying on the connection between cables and modules, the bending and torsion stress release device should be installed after the module is installed, fix the shielded c

equipped with a vertical axial, upward exhaust strong exhaust fan, but this fan has no effect on the current standard IT cabinet, because now all the rack-mounted IT devices are in the forward wind, rear air exhaust. Proper cabinet layout is important to ensure proper temperature and sufficient air. The "face-to-face, back-to-back" Cabinet layout method is adopted. In this way, the cold air outlet is arranged in the middle of the two racks to form a

It is inevitable to consider how to improve the high performance, high availability, high computing capability, and good scalability of E-commerce servers, and Server Load balancer. Due to the differences in the IDC network structure design, it is generally divided into front-end servers, application-layer servers, backend database

There are still many areas worth learning about in the smart Integrated Wiring System. To do a good job in the smart Integrated Wiring System, we should not only carefully design the scheme, but also design a reasonable scheme, pay attention to related matters during implementation. It is far from enough to send the "pain" of "neural peripheral" to the Administrator, simply sending a local prompt on the LCD screen of the Rack manager, you must also us

Generate several kilowatts of heat during operation, so there is a high requirement for cooling. Considering that a large data center is equipped with hundreds of racks, the detailed plan and careful planning are particularly important. The floor is raised through the bracket, and the communication cable trough is suspended under the floor. The space under the floor is used for air circulation. Racks and cabinets are installed on the overhead floor, and the floors are equipped with heating and

and weak current shafts ). 3) The use area of telecommunications rooms should not be less than 5M2 square meters. You can also adjust the size of wiring equipment and network settings installed in the project, that is, to increase or decrease the area of use between telecommunications. The calculation basis for the area used in the above telecommunications: In general, the wiring equipment and computer network equipment of the Integrated Wiring System are installed with 19 inch standard
