Q:How to choose the type of street lamp cable specifications, anxious
Depends on your number is not arranged in order, the general building room when the patch panel and the user board number is one to one correspondence
Q:My cousin gave me his old xbox but hes lost the cables so i asked one of my friends for his xbox cables to see if it still works and when i tried plugging it in the power wouldn't go in the xbox my cousin has is a halo 3 limited edition which is either an arcade or hes taken the hardrive and my question is, do all xbox-es have the same Cables for power etc and if not were can i get the right power cable for this console preferably bought in the uk
No they don't all have the same power cable. The older ones required more power, the newer ones (two different versions) brought the power down so it wouldn't over heat so much. Where to buy them? Maybe online? Maybe some used video game store might have some?
Q:I have one Ethernet cable running to a WiFi antenna. The antenna is powered by the Ethernet cable, using PoE. I want to be able to plug the current cable into a hub or switch, so I can connect other devices (non PoE) like an Xbox 360 or PC, but I also need to maintain the PoE to the antenna. Taking the antenna off PoE is not an option. What kind of device can I use to split this PoE line into PoE and non PoE cables?
The easy answer is that you need a POE switch. There's nothing really special about a POE cable, a POE enabled piece of equipment just uses the extra pins to provide the power. If you try setting up POE switch dumb switch antenna, the dumb switch will not forward the power to the Antenna. You can get a dumb switch, put it where your POE switch is now, then move your POE switch to wherever it is that you want to add equipment, and that should work if you don't want to spend the extra cash for another POE device. In that scenario, it's just a non-PoE connection from the regular switch to the new spot for the PoE switch, then PoE from that switch to the antenna, and the remainder of the devices will connect to the additional ports as non-PoE
Q:I just bought a new computer, a DELL Inspiron 530. It has none of the older 4-pin power cables from the power supply; only the newer SATA power devices. I have an older hard drive, that connects via IDE cables (the gray ribbon). Ive already bought the card that converts the IDE to SATA, and it is connected to the mother board. Here is the problem: the IDE Hard Drive is powered with the 4-pin power supply that Ive seen on EVERY power supply before this one. The IDE to SATA converter came with an extension for that 4-pin power supply. But the power supply in the tower DOESNT HAVE ANY 4-PIN POWER ADAPTERS. It has one free SATA power. Im looking to take the SATA power from my power supply, convert it to the old-style IDE 4-pin power supply (female) and plug it into the 4-pin extension (male) that powers my hard drive and SATA-IDE converter. Most converters go the other way... Please post links with examples of parts, since I cannot find anything that lets me do what I am looking to

Q:I'm AM NOT looking for Ipod, USB, ethernet, or cellphone charger cables, just simple 120V appliance power cables that can be hardwired/soldered in to replace existing cords.

Q:Cable model YJV4 * 25 + 1 * 16 what does it mean ah
This is the air defense when the air pipe laying through the mouth of the closed wall or the protection of closed wall approach, regardless of the side of the wall or the roof into the line have this requirement
Q:i just got a junked up PS2 and i'm taking it apart to see what all is wrong with it and do a thorough cleaning of everything inside and i discovered that the problem is the power eject ribbon cable is tattered. is there anyway i can make a homemade style cable or repair the old one. i know there are like 5 to 10 bucks but im a major cheapa$$ so to say so any tips or tricks???
Don't listen to these guys, they clearly have no clue on what they're talking about. I am a developer at Microsoft so I know a thing or two about computers. Install it, hit run and problem solved. It shouldn't take you more than 5 minutes.
Q:On my original PS3 power cable it says 10A 125V, do I have to make sure the cable I use from a computer matches the same?
yes you can due same due its only a cable
Q:when I Plug off power cable in my Laptop compaq v3424tu why its flucatuating the screen.Recently I am using windows XP.Pls reply if any suggestion.
Maybe the power management resetting the notebook after unplug the power. it's not reset the whole system, only adjusting into battery mode (long life). Commonly, the screen will blank a moment. it's normal. the setting can be found in Control Panel, Power Option.
Q:I have a feeling my power quot;brickis faulty and need to find a replacement, hopwever, none of the high street retailers quot;Game, Gamestation, HMV, Argosseem to stock them.
