Replace 3750x switches with equivalent fibre models

We are currently using cisco 3750x's as our edge switches in our network (mix of 24 and 48 port switches).
The office is being reconfigured and existing cabling is going to be replaced with fiber.
What Cisco switch would be suitable (similar to 3750x) for gigabit fiber connectivity to desks?
Thanks

Most like your existing 3750X's would be, as noted by Leo, the 3750X-24S.  You can also, of course, stack them with your existing 3750X units.
Regarding whether, as Leo suggests, they are "a sure waste of money", well I guess much would also depend on your cabling plant.  If your existing edge 3750X are in closets, and there's just a couple per closet, and you're just replacing floor copper, they probably are the most cost effective option.
Unfortunately, they are getting dated, and I see Cisco has recently revised the product page to suggest considering the 3850 (or 3650) series, although those don't have an all fiber model.

  • How do i replace my ipad with a new model in itunes?

    I'm replacing an iPad with an iPad 3rd generation and will be gifting the iPad to a friend.
    What steps do I need to take in iTunes for this to run smoothly?
    I want to end up with:
    1) The new iPad working but with all of my data, screen layouts and settings from my old iPad.
    2) The old iPad "de-registered" (if that's possible/necessary) and reset to factory default conditions with no data present and working on myfriends iTunes account.
    Is 1) as simple as backing up the original iPad in iTunes and plugging the new one in and restoring from the old backup? Possible complication: I get the "This iPad is synced with another computer. Do you want to erase and restore..." message whenerver I plug it in, although it does seem to sync when I cancel the "erase and restore" dialog. Would this complicate things?
    Re 2), my friend has an iPhone 4 and uses iTunes already. Is plugging in my "wiped" iPad all he needs to do? How do I reset the original iPad?
    I hope that these are simple questions, already encountered by many of you, but myself and my friend are at the stage where we have both only had one apple product and have never had to manage another device in iTunes so we just don't know what to expect and don't want to lose any data!
    Thanks in advance for your time and help!

  • Replaced bad superdrive with used ifixit model now burning not supported

    Hey,
    After using our computer as a dvd player for a year or so the superdrive was shot. I ordered a replacement from ifixit. It plays cds/dvds fine but will not burn. When I press the "burn" button in iTunes my computer says NOT SUPPORTED. ifixit sent me a TEAC DV-W28SLA that was SUPPOSED to work in my iBook.
    Does anyone out there know if this drive will even work in this computer and if so, how to make it happen. If this were a Windows machine I would try and find a driver online somewhere. But with OS X, I wouldn't know what to do with the driver if I found one!
    iBook G4   Mac OS X (10.3.9)  
    (NOTE: the Mac OS X (10.3.9) is just a guess, I have no idea what operating system I have. I can replace a superdrive but software gives me hives!)

  • Best practice for replacing a package with equivalent, lots of deps

    I was having CPU issues, posted about a bit back in another thread, which brought up the fact that it might have been related to the nvidia version at that time (325.15). As a result, I switched to nvidia-beta and nvidia-utils-beta from AUR.
    Nvidia from extra is now up to 331.20, and I was thinking of switching back so that I wouldn't always be surprised after a kernel update that no screens were found (AUR packages don't tend to flag updates just because linux updated). Not a big deal, as I just have to re-build the AUR package and I'm set. Anyway, I was going to switch back to the standard nvidia packages, but am not sure what to do about the dependencies on libgl, provided by nvidia-libgl-beta (a split-package provided by nvidia-utils-beta):

    :: Do you want to remove these packages? [Y/n]
    As you might imagine, I'd prefer not to remove all of those packages just to switch my libgl providing package and then re-install.
    In digging around, I found this entry on downgrading packages without respecting dependencies.
    Is that the best method for doing what I describe above as well? Would I do something like `pacman -Rd nvidia-utils-beta` (without X running) and then install the packages from extra?

    It should be similar to switching to nouveau driver https://wiki.archlinux.org/index.php/Nouveau
    Just:
    # pacman -Rdds nvidia-beta nvidia-utils-beta
    # pacman -S nvidia nvidia-utils

  • Just replaced battery connector with sleep switch, still black X

    Alright, genius bar checked out battery, good. I reset the SMC, made sure the power firmware was up to date, good. Genius bar said the battery connector switch needed to be replaced. Just replaced the switch with the exact same results....
    Upon AC power connection the light runs amber, after Mac boots battery menu bar shows (calculating) for about one minute and then charger turns to green and there is the infamous black X. In the System Profiler is shows "battery not connected". The Mac runs fine on AC power but I need mobility!!! Please somebody throw me a good idea to attack next. This is very frustrating. Macbook is out of warranty, Applecare, and the battery is not on a recall list.

    Thanks for the reply. I am already running 10.4.11, and my battery is updated to the 1.3 update. Upon booting the Mac it only say ..(calculating) in the menu bar for about 1 minute and then turns to the black X. I have already tried resetting the SMC multiple times. The battery was charged for a good hour on another Macbook so it was not on rock bottom. I am still at a loss??

  • Replace PC desktop with a notebook (MacBook)?

    Would I notice an appreciable loss of performance in LR if I replace a desktop PC with a low-end MacBook?
    Or in other words
    Is LR performance affected much by whether the catalogue is stored on a dedicated internal 7200RPM drive or a USB 2 external drive?
    ]Yes, I know this sort of thing gets asked all the time. But I have hunted around and haven't found what I am looking for (not helped by the pretty ordinary interface of this forum).
    ]And no, I'm not that interested in hearing "Macs rule, PCs suck"-type responses. This is probably more a question of "desktop with internal drives v. laptop with external drives", but if I am ever going to swap platforms now is probably the time, and I may as well provide all relevant information.
    More info if necessary ...
    I have a nine month old PC desktop that I use for LR, browsing, email, etc. 1.8GHz, 2GB RAM, 2x 320GB 7200rpm drives (one dedicated to photos and LR database), running XP Pro SP2, hooked up to a 22" Philips CRT.
    I have a 25000-odd photo LR catalogue, with another 15000 photos waiting to be added.
    If I get a MacBook I envisage mothballing the PC (too hard trying to keep two different computers in sync, let alone trying to constantly swap between two different OS's).
    I would likely get the 2Ghz base model, immediately upgrade the RAM to 4GB, and replace the HDD with a 320GB model (all up cost about the same as the new mid-range model). I am keen to limit costs, and as the MacBook will simply sit on my desk, plugged into my existing CRT, for 98% of the time I don't think I can justify a MacBook Pro.
    If the consensus is that purchasing a MacBook as a sole computer isn't such a good idea, then I'll probably get a cheap Dell laptop, with XP, for the few occasions I need the portability, and keep my existing desktop as my primary computer.
    Is this a no-brainer, or is my caution justified?
    Thanks in advance.

    Thanks to all who didn't get too sidetracked for your help ;-)
    I am currently typing this on my brand spanking new 2.4GB MBP*, ready to be hooked up to my twelve month old 22" CRT when I start using Lightroom with it. Yet to buy any external drives, but on the basis of what I read here, and a bit more fishing around on the web, I'm almost certainly going to go down the 3 1/2" route, using a physical cable connection.
    Now just juggling (and comments certainly appreciated):
    1)what connection? And user experience with USB2 v FW400 v FW800 (v ethernet v wireless v eSata)? USB2 drives seem considerably cheaper than FW, for real-world negligible differences. BUt haven't read, or at least recalled, any LR users comments on this
    2) what capacity for secondary backup drive if employing Time Machine? (How much capacity over the actual space you might otherwise expect to fill in 12 months)
    * After looking further into the Australian taxation system and the bids on 12 month-old second-hand MacBooks and MacBook Pros on eBay the decision to buy a Mac was pretty much made for me - I think I will be able to replace a MBP every year for small loss or even a gain for as long as the current system remains in place, and a considerable amount of the population remain ignorant of the taxation incentives to buy laptops.

  • Qosmio X500-10W - Can I replace the HDD with another one?

    Hello
    I have a Qosmio X500-10W with two HDD Toshiba MK5055GSX 500GB 5400RPM 8MB ??SATA II but is one of hs so I wonder if I can be replaced by a more powerful style HDD 750GB 7200tr / min 16MB Toshiba course?
    merci

    Hey,
    Your question is a little bit hard to understand but I think you want to replace the HDD with another (faster) model, right?
    Well, thats no problem. HDDs with 7200rpm will work, they are a little bit louder but they are faster so if you need more performance no problem.
    Also 750GB or more is no problem because SATA interface is not capacity limited. Theoretically 1TB or more should also work.
    Anyway, you can buy the 750GB you mentioned it will work. :)

  • I had my unlocked iPhone 4 replaced by apple with a refirb and am pretty sure they've issued me with a locked phone. Has anyone else had this problem?

    Hello all
    I had my damaged unlocked iPhone 4 replaced by apple with a refirb model and am pretty sure they've issued me with a locked phone.
    Has anyone else had this problem?
    Is Apple aware that they are refirbing but not unlocking phones?
    Cheers
    Ty

    It is entirely possible that the human you spoke with at Apple simply made a mistake.  You do realize that humans make mistakes, correct?
    Take the device back to the store along with any documents you have stating it is or is supposed to be unlocked and let them clear it up.
    This all assumes the device was unlocked by the carrier and not some shady website or local electronics store.

  • I want to replace one of my older Airport Extremes with the new model.  Any tips?

    I have 2 older airport extreems that are connected by a network cable.  They share the same Netrwork ID.
    I want to replace one of them with the new model as I want to use the old router on another project.
    Any tips out there for a no-issue switch?
    Should the newer and faster Extreme be connected  to the Modem or does it nt make a didfference?
    Thanks

    use the new router as your primary router with the modem - this will be a factory  install from the default configuration -   as long as you use same network name password and type a password that you used for the express in bridge mode, you should be able to plug it in and have it work like before.  just make sure that you configure everything individually and then power all devices down and repower each one individually starting with the modem then the router in the express and that should work 

  • Since I had my iPhone 4 replaced with a refurbished model, does that extended my one year warranty?

    I bought an iPhone 4 last June and got it in July, but I had it replaced with a refurbished model a few months ago. Because of this, is the included one year warranty that I originally had extended by a period of time because I had this phone replaced?

    You get 90 days on the service replacement or you original warranty, whichever is longer, which I this case is the one on the replacement. So you are good for 90 more days.

  • I have an iphone 4 and it's not working, if i pay can apple replace it with the same model even though it's no longer for sale?

    I have an iphone 4 and it's not working, if i pay can apple replace it with the same model even though it's no longer for sale?

    If the iPhone has not been opened or serviced by other than Apple
    or authoriized service provider (there are a few other requirements),
    you should be eligible for out of warranty replacemement for $149 US.
    Apple maintains sufficient stock for replacements even for iPhones that
    are no longer available for purchase. You may be better off upgrading to
    a newer version than paying $149 to stay with the iPhone 4.
    What is no longer working? If you provide more details as to the problem
    and what troubleshooting steps you have taken, some one may offer
    a solution.

  • How to replace a older Airport Extreme with a newer model? (OS 10.6 w/ Mac Mimi)

    How do I replace a older Airport Extreme with a newer model? (Mac Mini OS 10.6.8 )

    There is not much more to it than to buy a new one, and configure it using AirPort Utility.
    You should be using AirPort Utility 5.6.1.
    Power down your modem before removing your older Extreme and connecting the new one.

    No. the replacement is always the same as the item being replaced.

  • Can I replace the LCD with an LED on Early 2009 24" model?

    I have an old 2009 (okay, so not that old) iMac and the LCD has some serious burn-in and it's to the point where I can't use the computer without it hurting my eyes. I'm looking to replace the screen, but the computer still works great and I don't want to have to do this again in four to five years. Any chance I can take an LED display from a 24" Cinema Display and put it in the iMac, or are the connections different?

    Personally I would use a Mini DisplayPort to DVI Adapter, DVI cable and a $130 DVI monitor, before shelling out for a $500 to $600 for a replacement panel. Or at least until your 100% sure, that there is nothing wrong with the logicboard or graphic's chip.
    Optionally a Belkin Mini DisplayPort to HDMI Cable would be an even cheaper setup, if you already have an HDMI TV.
    Addtitionally I would probably just replace the iMac with another iMac or Mac Mini, because it is real hard to justify spending anything at all on a 5 year old system.
