More complaints against the new system
Earlier I have written that the new systems that they have sent us was somewhat not the one we needed, now I have a problem with one of the new systems in my lab. The LCD monitor stopped working. Suddenly it went blank. The power LED is still working but no display. Fortunately I have a old CRT monitor in perfect condition at my disposal. I just love CRT monitors for their reliability.

Receipt Printers
I was amazed to find that there are still receipt printers which uses thermal and inkjet technology these days. I though that most used dot matrix technology which provides very low cost printing. But I am wrong - Have a look at this epson receipt printer range. There are dot matrix, inkjet, thermal printers available in the market. Is the heat sensitive paper for thermal printers costlier than normal paper? I think so - but then I am not so sure these days.

Home Theater Seating
Whether you have just installed a fancy new home theater in a box from Denon or Sony, or you are simply excited about a more comfortable and ergonomic TV watching experience, here are some tips for constructing an ideal home theater seating setup. First, bear in mind that there are numerous types of seats, including rockers, loungers, and traditional furniture adapted to theater watching.
Typically, single and dual chairs are often priced higher than rows (three pieces or more interlocked) because it is easier (per unit) to mass-produce theater seating. Legacy theater seats can be bolted to the floor using butterfly screws, such as the Tapcon screw. Loungers and rockers can be moved around for your viewing convenience.
Where should you set up your home theater seating? Experts recommend taking a measurement of the diagonal length of your HDTV or movie screen. Double this length, and then measure from the base of your screen out into the viewing area. Center your seating. Once you have made these measurements, connect your audio system accordingly, so that you do not distort the sound field by putting any one speaker too close to the sitting area.
Once you have decided your sweet spot, it is time to shop fabrics and consider ergonomic choices. Leather, suede, and velour fabric options are all available. Assembling, un-boxing, and installing your own theater seats can take at least half a day, so be prepared to invest the time. Since there are practically no showrooms in the world designed to house theater seats, your best bet is to find well-priced theater furniture on the Internet.

Cell phone signal boosters
Cell phone signal boosters, including wireless repeaters and inline cell phone boosters or cell phone amplifiers, extend cellular service in poor coverage areas by amplifying both transmit and receive signals. These cell signal booster amplifiers reduce problems with dropped calls and signal fades while improving service range, voice quality and access. These multi-mode amplifiers are designed to offer a cost-effective solution for use in buildings and mobile installations.
Cell phone repeaters are an emerging technology of bi-directional cellular amplifiers. If you are suffering from weak cellular signal, then a cellular repeater system can help you by improving the cellular reception that you experience. It does this in two ways:
1. A cellular repeater system will include an antenna which sits outside your building, where the cellular signal is stronger, and feeds this strong signal into your building through a low loss cable.
2. The cellular repeater system actively boosts this signal through the bi-directional amplifier. It is a bi-directional amplifier because both incoming and outgoing signals are boosted.
After a rocky start, cellular repeater technology has much improved and now there are a variety of repeaters which are licensed by the FCC, the body which monitors the communications industry. Be sure to look for this endorsement when buying a repeater, but rest assured that all cellular repeaters from the established manufacturers such as Wilson Electronics, Clear Voice and Wi-Ex zBoost have this accolade included. Cellular Repeaters come in a number of different flavors e.g.. In-Vehicle versions, Large building versions and standard home/small office versions.
Cellular Repeaters (Wireless)
Wireless boosters improve the cell signal for multiple users simultaneously without a physical connection to the phone or device. Models are available for vehicle, home, office, RV and marine applications. Amplifiers are available both standalone and as part of complete repeater kits.
Inline Boosters (Direct Connect Amplifiers)
Inline boosters connect directly to a cell phone or cellular data card providing improved signal to a single user at a time. When combined with the appropriate cellular antenna they provide optimum cellular signal enhancement.

Sell your Used Cisco Gear: Helpful Tips
by Razvan Marian Jr @ articlesbase.com
Cisco Systems has become a name synonymous with high-quality networking hardware. It’s no wonder that many companies build their network around this brand. In addition to their robust feature-set and useful product life, Cisco products also have great investment protection and can be resold to help recoup a portion of their cost.
There are many reasons companies get rid of hardware. Sometimes companies replace dead equipment that is no longer functioning properly. In this instance, equipment can be salvaged or recycled, which amounts to getting small amounts of money for the value of the raw materials. However, more often companies are either upgrading or downsizing, in which case the equipment they are selling on the secondary market is still functioning perfectly but is no longer an integral part of a network.
There are a number of ways to go about selling your equipment on the secondary market.
EBAY
eBay is the world’s garage sale. Not only that, eBay is a great place to buy and sell used networking hardware. If you perform a search for terms like “cisco router” you will find a slew of models, both new and used to choose from. Often listed at low starting bids or “buy it now” prices, products can be acquired for a fraction of the cost of new. While these prices can sometimes be lower than what would be paid when sourcing from a reputable vendor, there are some risks that go hand in hand with buying and selling any network hardware on eBay.
For one, many eBay users post items that they may or may not currently have in stock. If an order comes in, they search the inventory of other brokers to find it at a lower cost than it was sold. This means that if they can’t source it immediately, you may be forced to wait for more time than you expected, while they source one. If you are selling used equipment, you will have to deal with buyers who may be suspicious about your listing. You should use clear language in your description, assuring the prospective buyer that the item you listed is physically in stock.
Secondly, there may be significant costs associated with freight and shipping. A fully loaded Catalyst 6500 model weighs a lot. You may end up paying a large amount of money to ship it to the buyer. This can sometimes be an unexpected cost the buyer may not be comfortable with. If you are shipping a piece of networking gear, make sure to always require insurance. This prevents any liability for items that are damaged in shipping. Since the shipper is the one who has to file a claim, this can be a real headache. Conversely, you can avoid the whole issue of shipping by stipulating that your auction will be “local pick-up only.” This means that you will not be required to complete the sale of your item if the winning bidder is not able to pick-up.
Lastly, you may be competing against vendors/members who offer a product guarantee. Most reputable vendors offer some sort of warranty for end-users, ranging from 90-days to 1-year. By not including a guarantee on your item, you may lose potential bidders who feel more comfortable having some kind of warranty on a large investment.
You can sometimes offload equipment quickly and easily on eBay; however, because of this fact, a number of established vendors utilize this service as well. In this instance, you are competing against a technology specialist who has the experience, inventory, and leverage to appeal to a large segment of buyers. In the end, your greatest weapon is price.
SECONDARY MARKET
The secondary market is a great, safe way to purchase used Cisco hardware. There are many vendors spread out across the country offering discounted gear and product guarantees. Because most companies actually house inventory, buyers stand a good chance of getting a required order filled quickly and packaged professionally. However, distance is still a factor when placing an order, as shipping charges can add substantial cost to an out of state transaction.
Finding the right company for you can be accomplished by performing specific searches in any of the major search engines. Instead of simply searching for “buy used cisco” or some other relatively general term, you can modify your search by adding a qualifying geo-specific keyword such as “San Francisco” or “sf.” The search phrase “San Francisco used cisco” will return a number of companies that are located in your geographic region, and thus will minimize shipping costs and transit time. Also, by using Yahoo’s local search filter, you can perform a general search like “buy used cisco” and then filter results to show only those companies that are physically located close by. All you need is to be logged into a Yahoo account to take advantage of this feature.
Specialized technology vendors may also offer full-service liquidation services to manage all aspects of the buying process, which minimizes the effort required on the part of the seller. Liquidation services make the most sense for companies with large amounts of hardware that they need to unload. Instead of finding buyers for individual pieces and sourcing a salvage company to recycle the unusable equipment, you can work with one point of contact who will manage all the logistics, transportation, and valuation of an entire lot of gear. This allows you to focus your energy on your core, revenue-producing activities.
The timeline from your initial communication and RFQ to an offer and full payment can depend on both the company and the size and type of the lot. Some companies offer a quote and deposit payment in as little as 48-hours of a RFQ, with the remaining balance paid upon receipt and inspection of all equipment. Your final offer will take into account the model/make, condition, and the current market demand for the used hardware. The entire process can take anywhere from 5 working days to 2 weeks. Make sure to find a company that you feel comfortable working with, as there a quite a few small brokers that do not have the capital or bandwidth to efficiently handle your business.
With adequate research and due diligence, you can find the appropriate marketplace to sell your used cisco hardware and receive fair value for your surplus equipment.
