R & M launches new generation LC Duplex compact fiber optic connector

Yasir Irfan Yasir Irfan Profile: Yasir Irfan


I started my career as a Structured cabling Designer, I am certified Systimax SCS guy, for me there is no better product than Systimax. I was literary addicted to the products from Systimax. I know Systimax since the days of AT&T, then Lucent Technologies, Avaya Systems and at this stage a Comscope company. No doubt Systimax SCS products are great. By it was my friend working as Area Manager R & M Saudi Arabia changed my perspective about R & M SCS products.


R & M happens to be Swiss cabling Specialist Company, which recently launched the new generation of its LC Duplex compact fiber-optic connector system. For the first time ever, this system has integrated laser protection and a lock for the connector. With these safety features, LC can now be used more easily in office buildings, residential buildings and highly com-pact computing centers.

According to the press release from R & M

“A laser shutter provides integrated protection against laser beams, an international first in this product category. A flat spring in the adapter opens when the connector is unplugged and covers the fiber stub. No laser beam can escape from the adapter. Any danger of injury is therefore ruled out, allowing the LC to be utilized risk-free in publicly accessible applications such as Fiber-to-the-Desk and Fiber-to-the-Home. R & M  also offers a semi-transparent dust cap that enables the connection to be visually checked safely.”

Building a Data Center! think green.

Yasir Irfan Yasir Irfan Profile: Yasir Irfan


We are working on building a new Data Center for our Organization, mean while I did lot of research and gathered some information on what standards the data center to be established. These days everyone is talking about the green Data centers, which triggered me and I was just thinking about our planet. Yes we will plan a green data center, but to do so we need some guidelines and standards.

 I figured out an ideal data center can be only established if we follow the TIA 964 standards. Following resources helped me to come out with an ideal RFP for the tender which we are releasing soon.

First and foremost the document published by Search Datacenter is good you should have a look at this document and the website has many valuable information related to data centers.  

APC does have lot of documents, the white paper published by APC by the title “Data Center Projects: Standardized Process” did help me a lot to draft the RFP.

Cisco Systems even though they never build data center but they do provide solutions and does have a dedicated section called Cisco Data Center 3.0 where you can find lot of valuable information.

Other web site which really amazed me was of Panduit, they really have data center solutions, especially the cable management stuff and the specially designed Net Access cabinets for the Cisco Nexus 7000 series Switches.   

R & M the Swiss cabling specialist does have special cabling products for the data center as well as their white paper is worth while reading as it contains all the information needed to build a green data center.

Hopefully we try to establish our data center based on the TIA 964 standards and ofcourse it will be green.

Yasir Irfan Yasir Irfan Profile: Yasir Irfan


It’s my habit to always  try something new or some interesting. As we have a huge project coming up, hence  I am in the process of testing many windows supported netflow analyzers.  Since I am aware of Manage Engine Netflow analyzer I thought for a change let me start over with Scrutinizer netflow analyzer.

I just went to the Scrutinizer web site and downloaded the latest Scrutinizer netflow analyzer; there support seems to be good, the moment I downloaded the  Scrutinizer netflow analyzer I received an email offering a trial key with few faqs of the Scrutinizer netflow analyzer.

FCoE (Fiber Chanel over Ethernet) is a standard now

Yasir Irfan Yasir Irfan Profile: Yasir Irfan


On 3rd June 2009, the FC-BB-5 working group of T11 completed the development of the draft standard and unanimously approved it as the final standard. The following day the plenary session of T11 approved forwarding the FC-BB-5 standard to INCITS for publication as an ANSI standard.


Cisco Systems has significantly contributed to the definition of FCoE in the FC-BB-5 standard through multiple technical submissions. Cisco has led the FC-BB-5 working group holding the chairman position with Claudio DeSanti.

One of the most significant technical challenges for the working group has been the definition of the addressing mode for FCoE, with two schemes proposed, FPMAs (Fabric Provided MAC Addresses, proposed by Cisco) and SPMAs (Server Provided MAC Addresses, proposed by Brocade). The final standard recognizes the superiority of the Cisco scheme by stating that FPMAs are the only addresses mandatory to implement.

The standard is at:

All of this is wrapped in an intuitive, easy to use interface that makes sense for LAN-sized installations up to complex networks with hundreds of devices.

The creator of this appliance Ernie did a great job by including nice collection of pre- configured open source software’s which includes the following


    – FreeBSD UNIX v6.2 RELEASE built to Ernie’s specifications
    – PERL v5.8.8 and many carefully selected modules
    – PHP v5.2.4 that I custom compiled from source

Following study materials will definitely help you to pass Cisco CCNA 640-802 Exams – Part 2

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

In my first post  I was talking about the books required to pass Cisco CCNA 640-802 exams, once you are done with The CCNA Official Exam Certification Library (CCNA Exam 640-802), and with the boson Exsim practice exams which are always very helpful to understand the concepts as well as an idea about the questions you might face in the real Cisco CCNA 640-802 exams.


The best idea would be to practice the labs , in order to ease this Cisco Press came up with an excellent product CCENT 640-822 Network Simulator, which is good for the gentlemen who has no exposure to real routers and switches, it’s good for hands on experience.  Also I have reviewed the CCENT 640-822 Network Simulator which explains the details of labs included with screen shots as well.

Cisco Press will release the next part of the CCNA 640-802 Network Simulator on 24th of June 09. SO that you can practice well for the labs covered in the Cisco CCNA 640-802 exams.
