PASANG KABEL LAN

Memasang Kabel LAN UTP (Unshielded Twisted Pair) untuk jaringan mudah-mudah susah....
yang perlu disediakan RJ45, Kabel LAN biasanya Belden(merk yang umum digunakan), Tang klip (Chrim), LAN Tester.

Kabel LAN Chrim (Tang Klip)

RJ45(Cross Adapter) RJ45

Lan Tester

Kabel UTP ada beberapa kategori , kategori 1 - 7 yang sering digunakan untuk LAN biasanya kategori 5 atau sering disebut cat-5. Berikut ini kegunaan dari kabel kategori 1 - 7 diambil dari wikipedia.
cat 1: sebelumnya dipakai untuk POST (Plain Old Telephone Service) telephone dan ISDN.
cat 2: dipakai untuk token ring network dengan bw 4mbps
cat 3: dipakai untuk data network dengan frequensi up to 16Mhz dan lebih populer untuk pemakaian 10mbps
cat 4: Frequensi up to 20Mhz dan sering dipakai untuk 16mbps token ring network.
cat 5: Frequensi up to 100Mhz dan biasa dipakai untuk network dengan kecepatan 100Mbps tetap kemungkinan tidak cocok untuk gigabyte ethernet network.
cat 5e: Frequensi dan kecepatan sama dengan cat-5 tetapi lebih support gigabyte ethernet network.
cat 6: Memiliki kecepatan up to 250Mbps atau lebih dari dua kali cat-5 dan cat-5e
cat 6a: Kabel masa depan untuk kecepatan up to 10Gbps
cat 7: di design untuk bekerja pada frequensi up to 600Mhz.

Ada dua Tipe pemasangan UTP yaitu : Tipe Cross dan Straight.
dalam pemasangan UTP yang paling penting adalah kabel urutan 1,2,3,6, sedangkan 4,5,7,8 tidak untuk transfer data.

Tipe Straight
ini paling mudah yang penting antara ujung yang satu dengan yang lain harus sama (sewarna).
standarnya adalah berwarna :

1. oranye muda
   
2. oranye tua
   
3. hijau muda
   
4. biru muda
   
5. biru tua
   
6. hijau tua
   
7. coklat muda
   
8. coklat tua
   

maka ujung yang lain juga mempunyai urutan yang sama.


Tipe Cross/Silang :
Cross cable biasa dipakai untuk koneksi dari PC to PC / PC to Router, Pokoknya semua koneksi dari alat yang biasanya koneksi melalui switch atau hub tetapi dipasang secara langsung. Berikut ini contoh posisi kabel dalam kondisi crossover.
model ini hanya menyilangkan antara ujung yang satu dengan yang lain.
1 ------> 3
2 ------> 6
3 ------> 1
6 ------> 2
sebagai berikut detailnya :
ujung yang pertama

1. oranye muda
   
2. oranye tua
   
3. hijau muda
   
4. biru muda
   
5. biru tua
   
6. hijau tua
   
7. coklat muda
   
8. coklat tua
   

Ujung yang satunya lagi :

1. hijau muda
   
2. hijau tua
   
3. orange muda
   
4. biru muda
   
5. biru tua
   
6. orange tua
   
7. coklat muda
   
8. coklat tua

Re: UTP - Standard TIA 568A-B

Nambahin dikit ajah, soal standar bukan tidak akan menimbulkan masalah jika tidak di ikuti? Afaik, standar itu dibuat sebagai panduan sekaligus kontrol performance suatu alat, dlm hal ini kabel UTP. Untuk standar yg seharusnya di ikuti sudah di atur dlm standar TIA 568A dan 568B, untuk kabel 'straight' dianjurkan untuk menggunakan 568B sedangkan kabel 'cross' satu sisi 568A dan sisi lain 568B.

UTP 568A dan 568B
Pemasangan UTP tidak mengikuti aturan Standar bukan tidak akan menimbulkan masalah. Standar itu dibuat sebagai panduan sekaligus kontrol performance suatu alat, dlm hal ini kabel UTP. Untuk standar yg seharusnya di ikuti sudah di atur dlm standar TIA 568A dan 568B, untuk kabel 'straight' dianjurkan untuk menggunakan 568B sedangkan kabel 'cross' satu sisi 568A dan sisi lain 568B. Ketika mengupgrade basis 10Mbps ke 100Mbps. apabila kita memasang UTP dengan tidak mengikuti Standar TIA sering menjadi masalah.


Cara Pemasangannya :
Kupas kabel LAN, bisa dengan Chrip Tools(TangKlip) di bagian untuk pengupas Kabel dan urutkan warna kabel yang akan kita pasang.
Ratakan Kabel yang telah terkelupas dengan cara dipotong, di Chrim tools juga ada bagian untuk memotong kabel.
Ratakan Kabelnya sebelum dimasukan kedalam RJ45.
Masukkan kabel yang tadi sudah diurutkan kabelnya dan sudah diratakan.
Tekan Kabel kedalam hingga kabel tersebut rata diujung pin.
Tekan Pin RJ dengan Chrim Tools.
Lalu Tes kabel dengan Tester LAN, pastikan semua Lampu menyala semua dengan baik.
Untuk Straight Lampu Tester akan menyala secara bersamaan.
Untuk Cross Lampu akan menyala secara silang, yaitu diurutan 1,2,3,6 (A) dengan 3,6,1,2 (B).
berarti sudah benar dan siap digunakan.

Kaspersky Anti-Virus & Internet Security 2010 9.0.0.736 - Final di 11/13/2009 01:43:00 AM

Kaspersky Internet Security 2010 9.0.0.736 - Final | 70.14 MB
Kaspersky Anti-Virus 2010 9.0.0.736 - Final | 64.17 MB

WHAT'S NEW IN KASPERSKY INTERNET SECURITY 2010:
Kaspersky Internet Security 2010 is a comprehensive data protection tool, which provides not only anti-virus protection but also protection against spam and network attacks. The application's components also enable users to protect their computers against currently unknown threats and phishing, and to restrict users' access to the Internet. The multifaceted protection covers all channels for data transfer and exchange. All components can be flexibly configured, allowing users to tailor Kaspersky Internet Security to their specific needs.

New in protection:
* Improved HIPS (Host-based Intrusion Prevention System) technology assigns a danger rating to unknown programs. The Application Control component uses HIPS to define rules for new and already known applications, which may restrict their access to the file and operating systems.
* Innovative Sandbox technology has been implemented, which uses virtualization to create a secure environment for program execution. New software can be tested in this environment, which isolates the host operating system from all changes. There is no limit to the number ofInternet browsers and other applications which can run simultaneously in a sandbox.
* Increased use of Kaspersky Security Network considerably decreases the threat response time, due to information received from other users. The service aims to minimize the time necessary to detect and neutralize new types of threats. When a user starts a program, the service checks it against white lists and Urgent Detection System lists on Kaspersky Lab's servers.
* The protection of personal user data has been extended and enhanced. For instance, Kaspersky Internet Security automatically prevents inadvertent users from accessing known phishing web sites, and blocks keylogger programs, which are designed to steal passwords and access codes.
* The new Script Emulator analyzes the behavior of scripts, to assess their potential harmfulness. It simulates the operation of the Java Script and Visual Basic Script engines, which are supported by default in Microsoft Internet Explorer and are built in to Microsoft Windows.
* The new IM Anti-Virus component ensures the safe operation of most instant messaging applications. The component scans messages for the presence of malicious objects.
* Improvements to the Virtual keyboard component provide safer entry of personal information, by protecting data from being intercepted by spyware and preventing screenshot capture.
* Significant improvements to the Anti-Spam component now provide two methods for detecting spam: exact and expert. Exact methods apply strict filtering criteria to a message, which determine unambiguously whether or not a message is spam. Expert methods investigate email messages that have passed strict filtering criteria. As such messages cannot be unambiguously considered spam, the component calculates the probability that they are spam.
* Components of Kaspersky Internet Security can be temporarily disabled, to improve computer performance. This can be useful during the use of resource-hungry applications such as network games.
* Monitoring access to phishing websites and protection against phishing attacks are performed by scanning links in messages and on web pages, and also by using the database of phishing addresses when an attempt to access websites is detected. You can check whether a web address is included in the phishing database, using the Web Anti-Virus, IM Anti-Virus or Anti-Spam component.
* Improvements have been made to all the application's existing components, including the Firewall, Parental Control, and Anti-Spam components, and particularly the Heuristic analyzer.
* The anti-virus kernel of Kaspersky Internet Security 2010 has been significantly improved, to provide more efficient malware detection. The application shows higher performance on Windows Vista operating systems, as compared to previous versions of Kaspersky Internet Security.
* Kaspersky Internet Security includes the URL scanning module managed by Web Anti-Virus. This module scans links on the web page, comparing the website addresses against its database of suspicious and phishing websites. This module is provided for Microsoft Internet Explorer and Mozilla Firefox browsers as a plug-in.
* The update procedure has been improved. Kaspersky Internet Security's databases are now updated not only according to their schedule, but also when new security threats appear.
* The creation of Rescue Disks has been improved. The service should be used when the infection reaches a level at which the computer cannot be disinfected using either anti-virus applications, or malware removal utilities such as Kaspersky AVPTool. The improved Rescue Disks provide more efficient disinfection because malware programs do not gain control when the operating system is being loaded.

New in the application interface:
* The application interface has been completely redesigned, to make Kaspersky Internet Security significantly more accessible to first-time users.
* Kaspersky Internet Security features an automatic mode in which the application automatically makes optimal decisions, so avoiding excessive requests to the user.
