are configured with 3 Seagate Barrucade 7200.7 120GB SATA interface hard drives and a RAID 5 mode disk array with ARC1120 SATA RAID cards. The optical drive device is a normal CD-ROM drive. There is no USB interface and no positioning indicator on the front panel, which will be slightly inconvenient to use. Super-yi 2806VS server Back IO panel provides 1 PS/2 mouse interface, 1 PS/2 keyboard interface, a serial port, a VGA interface, a Gigabit network interface (Intel 82

E1 cable, so can only use 100M cable instead, as long as the line does not do too long, should not be a problem.The interface of the E1 card is the Rj-48 interface. RJ48 is the interface for serial lines such as T1/e1, and the RJ45 of Ethernet is the same. For different transmissions, the signal definition is not the same, and I do this test by T1/e1 Trunk and Digital Voice Port (RJ-48). The following are the signals of each stitch: Pin1 Signal 1 rx

1. First confirm if there is a network card Check the computer peripheral interface for RJ45 network cable interface. Generally in the back. As shown in the following illustration: 2. If the computer is configured with a network card, see "Device Manager" has no network card equipment Right-click on the Desktop Small computer icon, select "Manage", select "Device Manager", and see if there is a network card device under the net adapter.

Technical features based on PON technology The PON system consists of optical circuit terminal (OLT), Optical Network Unit (ONU) and optical distribution network (ODN), which uses topological structures with dots to many points. Passive refers to all of the passive devices and optical fibers from Olt to ONU, and does not require any power source equipment. Pon All Optical Network has three networks in one business cap

Port Rate In addition to backplane bandwidth, throughput, and so on, the port rate is a measure of the switch is an important indicator. Now the port speed is: 10M, 10/100m, 1000M, 10/100/1000m. The corresponding interface physical characteristics are also different. When choosing a switch specifically, pay special attention to the higher port generation value of the high speed port.

on the convergence layer switch are flashing. After the investigation to determine the problem is due to the broadcast storm caused by a plug in the original switch on the redundant network cable was used by the company's staff to plug the other end also on the switch, both ends of the RJ45 interface to the same switch port caused by the whole network broadcast storm. The problem is solved when the network cable is unplugged. This type of wiring fai

"A typical datacenter environment is typically a room full of equipment and a security officer, and most of the data center floors are uplifted and the following space is used to place cables." But that doesn't mean they can be independent, even if they don't require the control of the device or the software. Hein continued, "We've invested a lot of money to build the best room to meet our 99.999% uptime n

physical and performance characteristics, 6 types of systems are different from those of super 5 systems. (a) Physical properties 6-type System products of the twisted 4-wire cable and RJ45 connectors are unchanged. Cabling system architecture and definitions have not changed. And almost everything else has changed. The entire 6-class system, which conforms to the current draft, requires all manufacturers to really redesign their products. The new

, as the original Super 5 systems are very popular. According to statistics, the 2005 class six system has occupied more than 60% of the wiring market share. But the fact is that all of the six types of systems that have been installed can only do the same thing as a super five system, that is, the Ethernet network that transmits the largest 1Gb, gigabit bandwidth, cannot be larger. The type of the 7-type system (the draft international standard defines a bandwidth of 1000Mhz) is not available f

Many readers have set up WiFi wireless networks in their homes. But do you think that the traditional wireless network construction is very troublesome? You know, before we buy ADSL cat, wireless router and so on multiple settings and smooth connection to implement wireless LAN. But now it's not so much trouble that we can make WiFi surfing easier with a t
