- Q:What are the phone, power, and cable companies in Pomona, Ca?
- Verizon for phone SCE (So cal edison) for power Charter? for cable I think. Get Direct TV it's better Gas is So cal gas.
- Q:cables? Power strip? thanks
- you will want HDMI cable for each component that has an HDMI connection. ie: cable box, home theater playstation3/xbox 360 whatever you may have the only way to make complete use of your 1080P is to use HDMI for everything you can. Power strip of course is a given. you should be good as long as you have the cables.
- Q:i hooked up all my 4 gauge power ground cable from the batteries of my truck i passed both of them thru the fire wall but what i was wondering is will i have a problem since its the power ground coming thru the same hole thru the fire wall or will i be all good ? somebodyy help
- you should never run your ground to your battery, to your amp.. it should be as short as possible, and attached to bare metal , like the frame. and if you have an issue with one, you could very quickly have an issue with both.. I REALLY hope you fused at least the power wire!!!!!
- Q:Copper core power cable laying cable sets what fixed
- BTS is 2G base station, a wireless network consists of N BTS and several BSC, each BTS need to access the BSC through the transmission network. 2G base station transmission interface is mostly 2M interface. SDH (Synchronous Digital System), is a technical system developed by ITU, is a transmission technology. SDH line side (that is, out of the cable) is 155M, 622M, 2.5G, 10G optical interface. Branch side (then business network equipment, including base stations) are more than 2M, FE, GE also has 155M optical interface. DDF and ODF are patch panels, DDF digital patch panels, ODF fiber patch panels. SDH line side of the ODF frame, is received on the outgoing cable, DDF frame service network equipment, in the base station is then BTS. Set the patch panel is mainly for easy maintenance, you can label on the patch panel, each interface business type is very clear. The communication system diagram in the base station is this: BTS - DDF - SDH - ODF - another bureau.
- Q:I don't want to run it under the car, but I can't find a place to run it through the firewall... Do I need to drill a hole?
- Look under the storage compartment on the passengers side. look under the dashboard on the drivers side, locate holes then look on the inside of the cars side skirts you should be able to remove the skirting and lay cable under there.
- Q:a usb cable has 5 volts and 2.5 watts. so can it still power if it has 5 volts and 1.5 watts
- Uh...YES! The voltage matches and the current will be regulated by the resistance of the device being powered. It will work fine.
- Q:When i want to connect two SATA hard drives do I need some power cable on slave or just to connect it with sata cable and that'it? Because I did it like that and it's not recognized. And I don't have second SATA power supply cable in my computer.
- Don't have to worry about master/slave with SATA, however, if you also have EIDE hard drives in your system, you may have to set your BIOS to enhanced or some other cooperative mode to use them all at the same time.
- Q:My friend I were going to play his second Xbox 360 n his living room. Went to turn it on and the RROD turned up with three lights. So we took this one and hooked it up to the cables in his room. And guess what? No RROD... So, I am lead to belive that the Xbox 360's power cable is the one that causes the RROD. Only problem is that most people can' test this due to not having a second power cable. So post your ideas about this idea. Could Microsoft be lying to us by saying that the malfunction is inside there console. I'm only 14 and i figured this out. So, how is it that no one else has??
- The xBox gadget has overheated and could no longer artwork except it gets repaired. subsequently, the three RRoD. under is a internet site that sells a selfmade restore equipment, yet once you're no longer extremely technically savvy, i'd advise getting it professionally repaired. Microsoft expenditures $one hundred is the prolonged guarantee is void. further: My undesirable, you're top that that's hardware failure fairly than overheating; that's been a on a similar time as on account that i've got worked on my own and that i could no longer think of of a extra useful thank you to describe it.
- Q:I took a vacation last week in Victorville, Ca and i brought my 360, well when i was ready to come back home i packed everthing but my Xbox 360 power cable, now im stuck at home and can't play my 360 or nothing..=[. And i don't wanna order it online. I need some help where to find this.
- are u missing the whole power source or just the end cable? the end cable is the same power cord has a computer
- Q:how do i install the power cord on the 8600 gts. Is just attaching one of the two receivers on the cord to the graphics card and the other end plug in one to a power thing the right way.
- Some specialized power supplies have the power cable built-in and you can plug that directly into the card. If you don't have one of these, then the card probably came with a cable that requires you to plug in two 4-pin power cables (same type that plugs into your CD drive off your power supply) and then the other 6-pin end snaps into your video card.
