Substitutes for Pricey Cable, Radio, and Phone Services

Web-based technologies can offer services that can work as great, cost effective substitutes for Cable TV, landline phones, cell service, and DSL. These are the next wave – they offer cheap services and same functionalities. You even get discounts, special offers and the like. Read on to fine out more about it.

Substitutes for TV and Movies

Services like Apple iTunes, BlockbusterOnDemand, Zune, Amazon, and Jaman give you thousands of shows and movies on a paid, per-show basis somewhere around $3 for a movie and $30 for a full season of a premiere TV show. Moreover, sites like Hulu, Crackle, Comcast, and many others offer free movies and TV shows. And all of this is without even mentioning YouTube.

Substitutes for Phones

Services like Skype, RingCentral, Google Voice, my1voice, and other VoIP services offer great replacements for calling up people from your landline phones at extremely low rates (or even free).

Then there are services like Truphone and Fring to replace your cell phone – and others like SpinVox, YouMail, PhoneTag, and Google Voice to replace your voice mail service. Further, you can send free SMSs from any of the IM apps or email abound on the web.

The exact features of the service might vary but the fact they cost almost nothing is something that is common in all of them.

Substitute for Satellite Radios

If you don’t want to shell out huge subscription charges for that expensive satellite radio, you can consider some of the web-radio services like Last.fm that is absolutely free. Although some others like Pandora may have paid versions, these radio services make the radio experience mobile by letting you tune in from your smartphone. You can even think of chucking out that old car radio once you get used to the internet radio services.

Although some of the older generation services of say, cable service providers, may still be necessary given your lifestyle – you can think of going for the minimal subscriptions to these services. Explore the web – and unleash the content that is being offered for almost next-to-nothing costs.

How To Verify If There Is Any Problem With My Monitor / Repair A Monitor Which Is Not Working

This post is part of the series Boot-up Troubleshooter.

When you are having boot up problems, the easiest one to troubleshoot is the monitor.

First check if the monitor’s power lights are glowing. If it isn’t then may be it isn’t getting any power. Check power cables and sockets to make sure all the plugs and cables are working fine. If you have one of the new monitors, then you’ll have some flashy message of some sort shown up on the screen which indicates to you that something is not fine with your monitor.

Sometimes it is very obvious, but then I’d like to still point it out, check the ‘brightness’ setting and make sure it’s not turned down inadvertently.

One of the other common cause can be because of the Windows application, Advanced Power Management (APM). Using APM users can set time out for different components of the system to go to standby mode. This is very useful to save power. When APM is used to set time out for monitors, a slightest movement of the mouse will bring the monitor back to life, if it’s gone to the standby mode. You should make sure if this is working fine and is not the cause of the problem.

To check that APM is not enabled by default on your PC,

> right-click the Desktop, click Properties,

> Screensavers –> Settings.

From here you can alter the APM setting to your choice or turn it off completely. Advanced Power Management is a Windows application that can cause a monitor to appear to be ‘dead’ Always check this possibility first.

Well if everything seems to be right and still the monitor doesn’t show up, then try replacing the monitor to with a working set, this acts as the last line of defence. This will let you know if the monitor is faulty and if it is, then you should think about a replacement.

Monitors are dangerous and lethal in terms of high voltages they carry. You should try and look inside only if you have enough experience. If not apart from risking your monitor, you may be risking your life as well !!

What Is Over Head Cabling

As opposed to a raised floor cabling deployment an overhead deploymet has all the cabling such as power network and so on running above a false overhanging ceiling and are terminated through the ceiling and rack vents to the Rack patch panels.

One of the key benefit of false ceiling based cabling is that it is less expensive that a raised flooring. Even sometimes if the cooling system is not going to share the same false ceiling then a false ceiling can be completely avoided and only simple raceways can be mounted on the true ceiling and cables can pass through that. It would obviously cut down your cost significantly but the aesthetic look of the room will go for a toss. Plus, as the wires are open in this case, they are more prone to accidental damage.

Also, here gravity plays a major role in disturbing the deployment. Due to the weight of the wire itself, they can come out from the patch panel and get disconnected. So, here try avoiding any kind of suspended cabling and try to use the cables which get properly locked after connecting.

But one more major issue with overhead wiring is that in such case if you are going to couple the same space ( between the false and true ceiling ) for both cabling and circulating chilled air, it become somewhat difficult, because by virtue, hot air is supposed to rise up and cold air is supposed to settle down, and hence pushing cold air from top instead of using the top for venting out the hot air from the top is not the ideal situation.

And if you even don’t couple both cabling and cooling to the suspended ceiling then also it posses a challenge because you can’t have exhaust vents on the top because first the cable will get bad due to the constant flow of hot air through it and second they will create obstacles for the hot air to go out efficiently making it difficult. But for a small datacenter with lesser number of servers and racks, keeping the cost factor in mind suspended ceiling is a better choice

What Is Raised Floor Cabling

In a standard raised floor cable setup. Horizontal and vertical bars are placed on the actual floor which creates a raised grid like structure. Inside this grid, flat panels are fixed and under this raised surface, all tupe of cabling is laid out. In some cases the chilled air is also pumped through this false flooring.

Raised floors is a good in terms of aesthetics as long as the complete cabling goes beneath the false raised floor and reaches the servers through the bottom cable sockets of Racks. So, it is mostly invisible from outside making the place look cleaner and neat. The other benefits of Raised Floor cabling are heat management and easy access to the hidden cables.

Cables in a raised floor setup should be run through the raceways ( cabling channels ). This helps protect them from interferences caused by power cables, security devices and fire suppression systems which are also generally laid down in the same raised floor area. Raceways also help in the distribution of cool air.

Almost all type of cabling such as structured network cabling, electrical cables, KVM wires and if required telephone wires, all go through this grid and pass through the bottom of each rack location power receptacles. Then these wires are passed into and connected through the Rack patch panels. The child air is pumped to the room through the placement of solid and perforated floor tiles.

And as discussed earlier using a raised floor setup one can make most of the patch cords and pathways invisible by keeping them away from the sight. This not only enhances the aesthetic value of the room but also makes the devices less prone to damage or getting manhandled.

But, one problem which we face most often with false flooring deployments is that, if your datacenter is scaling up rapidly and you have not planned the growth properly while deploying the datacenter, then there is a chance of the false flooring not taking the load of the equipments. But with a bit of planning such kind of issues can be tackled easily.

What Are The Different Type Of Cabling Techniques In Data Centers

We take a look at most commonly used cabling techniques in data enter and discuss their advantages as well as downsides.

There is a dire need for better cabling management in your datacenter. It’s not just about the network cables, but also the KVM, Power and all other sort of cables which you use in your datacenter. Cabling management, if not done properly, may lead to major operational complications such as cooling problems difficulty in identifying cables, performance loss and so on.

Cabling Pathways
As we all know datacenters have high density networks and equipment. And, high density equipment requires high density cabling systems. These high density cables are essentially Flat ribbon like cables which eat uo less area and can be easily stacked and structured. Higher density cabling components can help reduce the amount of floor space, rack space and associated costs.

Along with the high density cables, proper cabling raceways and pathways in the datacenter are a must. These pathways make sure that the cables are isolated from any other kind of interferences. So for example, a network cable and a power cable running parallel could cause loss of quality in the network stream due to interference. The raceway makes sure that the cables don;t just hang in between and get tangled.

Generally the pathways consist of a combination of accesses under a raised flooring system or overhead cable tray or both. Now we will have a look into the difference and benefits between the two approaches :

1> Raised Floor Cabling

2> Over Head Cabling.
