2 GB, and a disc drive with an EIDE interface. 2 ). five 9332 m fast Ethernet NICs, such as SMC 10/100 EtherPower (four cards are used to connect nodes in the cluster, and the other one is used to connect one node in the cluster to other networks .) 3). Five RJ45 cables that are sufficient to connect each node in the cluster system using five unshielded twisted pair wires 4). 1 Fast Ethernet (100BASE-Tx) hub or switch 5). One Linux installation d

provides a common RJ45 interface) it is used to connect to the corresponding switch. In addition, you can physically Insert the HBA into the PCI or PCI-E slot as a nic, so the usage of this device is very similar to a nic, many people confuse it with a common Nic or a common fiber optic Nic. Of course, some iSCSI HbA cards can be used as common network cards, but the price is very luxurious. The conventional definition of HBA is the I/O adapter that

Vro configuration is not easy for beginners. As a basic knowledge of vro, this article takes Cisco2501 as an example to introduce the general configuration process of vro for your reference When configuring vro. Cisco2501 has an Ethernet port AUI), a Console port RJ45), an AUX port RJ45) and two synchronous serial ports. It supports DTE and DCE devices, supports EIA/TIA-232, EIA/TIA-449, V.35, X.25, and EIA

What are the six parts of the integrated Cabling System (note)? What is the composition of each of the six parts?1) Workstation subsystem, horizontal routing subsystem, inter-

type of panel usually does not include dust spring covers, but uses a plug-in type dust cover. The advantage is that the RJ45 module can be installed on the panel in any way of 90 ° or 45 °, and has good functions. Another European style is represented by French, German, and British products. These panels are usually equipped with dust-proof spring labels and replaceable labels, and their products are quite elegant, fully embodies the personality sty

ANSI/TIA-1005 standards, type 6 cables or better cables can be used to connect hosts or devices in industrial environments. Category 6 cables Support 1 GB network in the range of 100 meters and 10 Gb network in the range of 55 meters. The 6e Cable supports 10 Gb network in the range of 100 meters. Compared with Category 5 and category 5e cables, Category 6 cables are not susceptible to crosstalk and external EMI noise. Industrial Ethernet cables are designed to withstand physical erosion of cab

achieve 10GB network within 100 meters. Compared to Category 5 cable and 5e cable, 6 kinds of cables are not susceptible to crosstalk and external EMI noise. Industrial Ethernet cables are designed to withstand the physical erosion of cables by a more severe industrial environment. When installing type 6 cables, ensure that the RJ45 connectors and sockets are also up to 6 classes. The best way to do this is to use a predetermined plug cable and inst

, connect the crystal Head of the network of professional nouns known as RJ45 connection sockets, is specifically used to connect the ends of twisted-pair lines. By making the RJ45 connection header, we can connect the network cable with the network card or concentrator device. The crystal head of the market a good general piece of money, the best to buy those crystal head material more hard brand credit, s

Tools for making crystal head of wire Wire pliers (for connecting crystal Heads) In fact, the tool is very simple, on one, the production is also very simple mainly to pay attention to the Crystal Head model, now the most commonly used standard is: Tia/eai 568B, there is a tia/eai 568A their wiring slightly different, making crystal head first will be crystal head with a card down side, there are copper side facing up, The one with the openings facing its own body, sorted from left to right 12

Second, the standard development direction of copper cable wiring system In the Gigabit 1000base-t and the following Ethernet transmission medium, CAT5e, Cat6 and so on copper twisted pair line has the absolute superiority, along with the copper cable twisted line as the transmission medium 10GB (million Gigabit) Ethernet IEEE 802.3an The 10GBASE-T specification was formally approved in June 2006, which supports the

In discussing this issue, a problem needs to be made clear: we know that in the early San storage system, the data transfer between the server and the switch was done through fiber, because the server was transferring SCSI commands to the storage device and not the IP protocol of the normal LAN network, so it needed to use FC transport. So the SAN is called Fc-san, and the late advent of the San with the IP protocol package, you can completely walk the normal LAN network, so called Ip-san, which

Whether it is a LAN, a metropolitan area network or a wide area network, it is usually made up of networking devices and transmission media, such as NIC, hub, switch, router, cable, RJ45 connector, etc. As the scale of the network continues to expand, the number of devices that make up the network is expanding rapidly, equipment varieties are also constantly refurbished, if the day-to-day maintenance of these equipment, not regularly to their maintena
