It's not only the selection of the appropriate type of server racks and cable that you purchase, but the management of the cabling, power, and heat generation that are very important.

CABLES

Cables can be fed into the racks from above (ceiling) or below (floor) and organized with vertical or horizontal cable managers inside or outside the racks. Depending on the type, number, weight, diameter, etc., cable guides must be chosen to supply the optimal solution. This depends on whether you have copper cables (Cat 5, 5e, 6. 6A, 7) and the specific manufacturer. Fiber optic cables vary if they are duplex jumper or multi-fiber cables (MTP) and by manufacturer. We have supplied various inside rack cable management solutions including patch panels, managers with fingers, loops, rings, and outside rack solutions with ladder racks, cable trays, cable runway, etc.

POWER

There are many levels of power units (usually 15, 20, or 30 Amp) available to supply power to the switches and servers mounted in the racks. These units vary from basic multi-outlet power strips without breaker or switch to mutifuction units including Amp meters, temperature, and moisture sensors. Some units can be accessed from a remote office or home on the Internet.

HEAT control

Server rack cooling in the datacenter rack space depends on the number of switches and servers, as well as the arrangement of the rackmount server cabinet and cables. Too many copper cables in the floor can block the free flow of cooling air. The size and layout of fans and blowers installed in the racks affects the efficiency of cooling. The use of cold aisle/hot aisle cabinet arrangement to keep the hot air from mixing with the cold air can help the data center run much more efficiently. Details such as the watts/rack and the BTUS to be handled are important in the accurate design of a computer center so that sufficient cooling is supplied.

WPA upgrade to WPA2

TO upgrade your wireless network security to WPA2 follow these steps:

1. Upgrade your wireless routers firmware to the latest firmware. linksys and Dlink wireless routers manufactured in the last two years will have WPA2 compatiable firmware ababilable.

2. Download the windows xp patch for WPA2

3. Download your wireless adapters most up to date firmware.

4. After you install your new firmware and driver restart your wireless router and computer.

5. Now go to your wireless routers web interface, proceed to the security tab and choose WPA2. You will have the options of WPA2 Mixed , WPA2 RADIUS and WPA2. Mixed WPA2 will let you use either AES or TKIP encryption. WPA2 by default only uses AES. WPA2 radius uses AES and will authenticate users via a RADIUS server. Home users should use WPA2 mixed or WPA2. Enter in your passphrase and logout.

6. Some wireless adapter will not let you use windows xp zero confifuration utility to run WPA2. Some companies will make you utilize their third party software for WPA2 support. This is often the case if you are using Windows 2000 or using a older adapater. To configure your adapter go to the adapter properites choose wirleess networks and choose which network you want to configure. Choose the same WPA2 option that you selected on your wireless router and enter the passphrase.

7. Dont forget to make your passphrase as compicated as possible to avoid brute force attacks
