Nexus 5548UP L3 card swap out for L2 cards

Hi everyone,
I have two Nexus 5548UPs and I am going to swap out the L3 cards and put in L2 cards.
I can't seem to get a straight answer out of TAC so I thought I'd try here.
How will this affect the current configuration (apart of course from removing the L3 capability)?
Will swapping the cards clear the config?
Will swapping the cards clear the licenses?
It's a very simple config so that doesn't worry me that much .. but if it will clear the licenses installed than I need to take action on that.
Thanks,
BR

I made a mistake without realising and the interface e1/3 was showing "Interface Ethernet1/3 is down (Inactive)". After spending sometime trying to figure out what was wrong with that interface or switch, it turned out to be that i forgot to add the vlan 40. Now the config looks like this:

When battery being calibrated fully depletes, can I swap out for another?

My question is about calibrating a battery, based on Apple's instructions (http://support.apple.com/kb/HT1490).
I have two batteries for this computer.
When I'm calibrating one of them, and get to steps 4 and 5, and the computer has shut down, does the battery being calibrated need to remain in the computer, thus rendering the computer effectively out of service for the five hour duration? Or can I take it out, and either use the computer from AC power or another battery?

It's best to leave it in during forced sleep yes. The idea is to drain the battery as low as possible - after the MBP is goes into forced sleep, it's still pulling charge from the battery to power the RAM. After a while in that state, though, the MBP often powers off completely. If that occurs before the end of the 5 hour hold period, it's fine to pull the battery and use the other, then shut the MBP off, put in the discharged battery, and connect to AC before charging to full/

Swapping out Graphics card on HP Envy 17-k251na

Hello! I have a feeling that i may have been given the wrong information by the assistant i bought my machine from in PC world...
I was assured i would be able to swap out my graphics card, which is a NVIDIA GeForce GTX 850M (4 GB DDR3 dedicated)
and upgrade.
I was also told i could upgrade the processor.
I've been told by a few people that this simply isn't true and to upgrade the Graphics Card i'd need a whole new motherboard... but the term "dedicated" is what's confusing me... am i wrong in thinking that it works seperately and the term "intergrated" means that it's part of the motherboard?
I spent a lot of money on this laptop on the premis of what the assistant told me! Ultimately that i would be able to upgrade this laptop as time went on. (I want to primarly want to use this for gaming)
I'm hoping what people are telling me is all hear say.. it doesn't seem to make sence to me that i can choose between two different graphics cards to run games with and they'd BOTH be intergrated into the mother board....
The other one that's in my machine is an Intel Graphics HD 5500.
Also this machine has a 1 TB HDD and an 8GB SSD, i'd like to also swap out for a larger SSD... i was also told that this was possible.
Hoping for good news here, any help woud be appreciated!

Right now the links to your product manual are down but assuming the 17-k200 series is like the 17-k000 and 17-k100 series there is no easy access to the hard drives and memory. That is, no customer accessible panels on the bottom you can open by just removing a screw. Further, there is no graphics "card" to just "swap out". "Dedicated" and "integrated" refer to the use of memory. An integrated video card shares system memory; i.e. the RAM supplied by the RAM modules you clip into the RAM slots. Dedicated video memory is memory built into the video chip. On a laptop, both kinds of video cards are soldered to the motherboard and cannot be upgraded. Your laptop has "switchable" graphics and most definitely has two different video chips soldered onto different places on the motherboard.
As for the processor, you already have one of the newest and best laptop processors offered. The video you have is also pretty top-notch. I am always a bit baffled by people who buy a laptop with the idea of upgrading it. Laptops just do not work that way. Components are way crazy expensive. Your processor is so new there are none to be purchased but when it does become available it will be over $350. On the very few super expensive engineering and high-end gaming laptops that do have a kind of removeable graphics card (mxm) high-end ones run at least $450. So even if you could do the upgrades, which you cannot, you would be looking at over $1000 with labor. I understand people do not appreciate the cold reality of this.
And just to hit you with more bad news, on your model the CPU might be soldered to the motherboard so it cannot be upgraded at all. I can confirm when your Manual is back online.
Upgrading memory and changing the hard drive for an SSD also requires extensive complex disassembly.
You have one of the best consumer laptops on the market. There is just not much upgrade headroom. It sounds like what you really want is a gaming laptop. HP makes one called the Omen which sells for about $1500-1800US, and would be a little stronger than what you have, particularly in the graphics. But even that is kind of a middle of the road thing. You can order a custom gaming laptop from a company like Sager and it is going to cost upwards of $2500 for the very best. Maybe you can complain to PC World and just return the one you have and start over a little wiser for the trouble.

Thinkpad Edge S430 - Swapping out optical drive for HDD?

Hi There
I just ordered myself an S430 with a 128gb SSD HDD included. I didn't see an option to replace the optical drive with a secondary HDD (e.g. a 500gb) so have the optical drive in as standard. Now, I would have rather changed this out for a secondary HDD or for a Blu-Ray drive, thinking I could do this myself once bought...Looking at other posts it looks like you can swap out the optical drive for a Blu-Ray drive, although I would preferably get a secondary drive over the Blu-Ray, but I'm hesitant over a few things:
Is this possible to do myself (swapping out for either secondary HDD or blu-ray drive) without voiding the warranty? (I got it with 2 year warranty)
Is it actually possible to do at all? (swapping out for a secondary HDD)
Thanks
Solved!
Go to Solution.

Unfortunately, I have found no hard drives that are compatible for your optical bay. I do believe the reason you can change out your optical drive is to change to a blue-ray or CD, or DVD, maybe a player or burner. But like I said, I have found no hard drive that can fit in your optical drive. You may be able to find what I could not but I have been looking all over the web.
I know how you feel, my computer at home can not have any hard drives in the optical bay as well.
Best regards,
Alex

Swapping out CD rom's

Hi all,
First i would like to apologize if i am posting in the wrong area. My friend gave me a older mac and i have no idea what type it is or anything. No model # on outside. I can describe it to you.
It has 2 handles. One in the front and one in the back. It is all gray. The drive in this MAC needs to be swapped out for a good drive. Can anyone tell me what type of MAC I have and how to remove the CD drive. The drive is enclosed in a case and there was only 2 screws in the drive from what i can tell, but the drive doesnt come out. What else is holding it down?
Any help will be appreciated.
Thanks,
Chris

Sure sounds like a G5. Maybe you could find it by looking through this site:

Yes, there are third-party cards that will work. QuickerTek has one that should work.

Can I swap out a iPhone 4 sim card into a iPhone 5 with the same carrier?

Here is the situation. I used to have Sprint as my personal cellphone carrier and just had bought an iPhone 5 when my employer put me on a business cellphone plan that they pay for. They bought one of the bargain basement original iPhone 4 handsets (not to be confused with the 4S) for employees to use, also on the Sprint network. The phone is owned by them; the plan is paid for by them. We just get to use it. As a result, I decided to just close out my personal cellphone account, even though it was a better phone. I used my 64GB iPhone 5 as my iPod, it worked great for music, apps, books, etc that I needed, and I just used the 8GB iPhone 4 just for phone calls and text messages.
Well recently, with the 5C and 5S being released, I wanted to know if the iPhone 4 could be upgraded by my employer to a new handset, preferably a 32 GB 5C or a 16 GB 5S. My employer has been slow to respond, because there are so many employee accounts to weed through and most are perfectly fine with an older phone. I am not, because the new operating system is slower on an iPhone 4 than an iPhone 5.
I want to ask my employer if its possible to get the SIM card from the iPhone 4 just swapped out into the iPhone 5. Is that possible? I understand that there is a size difference in the SIM cards. Is this something I could do myself, just pop it out and pop it in in the new handset? Or is this something that will require going to my employer to do, or to a Sprint store and have them do it? Do I have to be concerned with warranties being voided if I want to do this? (Keep in mind the iPhone 4 is my EMPLOYER's property, and they pay the bill as well. My inactive iPhone 5 is MY PROPERTY and has no current cellular service.)

I want to ask my employer if its possible to get the SIM card from the iPhone 4 just swapped out into the iPhone 5. Is that possible?
No, iPhone 4/4S uses micro-sim and iPhone 5/5C/5S uses nano-sim.

LMS User Tracking for NEXUS 5548UP

Dear,
A while ago I received a ticket from one of our customers because User Tracking was not working for NEXUS 5548UP on LMS 3.2. I opened a TAC case for this but this was normal since it is a Datacenter switch. Now the customer came back on this because they really want to see which server is connected to which switch port. I understood from the TAC engineer this is not on the roadmap to integrate in LMS 4.x. They want to know if there exists another product (they thought about DCNM) and wanted to know how this integrates or works together with LMS...
Kind regards,
Sven Laureyssens

My latest understanding of User Tracking and Nexus 5K series is that it is not supported due to a limitation of the MIB support in the NX-OS.
The current DCNM (release 5.2) is distinct from the LMS and Cisco Prime umbrella but that wil be changing a bit moving forwad as DCNM is enhanced and rolled into the Cisco Prime family. Last I heard there should be some information coming out of Cisco Live this week and a new release will have some additional functionality and better integration. Still, I doubt we'll see UT for the 5K due to the NX-OS limitation.
One way to do what you're asking apart from use of any of the Cisco products is to enable LLDP on your Nexus and servers. That will at least give you the ability to pull the information from the NX-OS command line ("show lldp neighbor")

Graphics Card Swap Outs

PCs using MS operating systems can just swap out graphics cards. I want to buy the 17" MacBook Pro, but want the ATI Mobility Radeon X1800 instead of the 1600 currently packaged in the system so I can game as well as use it for business.
Question: Can you just swap out the 1600 and replace it with the 1800, or is the proprietary system too inflexible to allow that? A wantabee Mac owner.....

I want to get a 17" macbook pro with an upgraded ATI card, the 1800 or the 1900 - but there is NO WAY TO TALK TO TECHS! It is not a hard switch, bet there is no special requirements as it is just a faster model that fits in the same PCI express slot. I want someone IN THE TECH DEPARTMENT to tell me that the Mac is so propriety that it is totally inflexible to make that adjustment. OR, tell me that the new operating system 17" will have the new 1800 or 1900 ATI card - I will wait to buy then. Otherwise, I will go get the Dell 2010 that has the 1800 already in it (BUT i WILL NOT BE HAPPY ABOUT THE BUY.) By the way - it was your own sales agent at an Apple store that told me the 1600 was a dog compared to the 1800.....

Swap out 1.25DP for 1.42DP?

Hello everyone,
Happy Columbus day holiday to everyone(for Monday). I have presently a Power Mac G4 MDD 1.25DP machine with 2GB memory. Is it possible to swap out the 1.25DP for the 1.42DP, and if so, what kind of speed/performance am I really going to see? First off, is it worth it? 2ndly, will I notice anything at all with the DP 1.42 in place of the 1.25DP? Bear in mind, I am not looking to go to another machine, as I just got this MDD machine and love it very much compared to the G4 Digital Audio machine I have.
I did some research and it appears that the dual processor 1.42 has the same bus speed as the 1.25DP MDD machine. Therefore, is it possible to swap out the 1.25DP and insert the 1.42DP? I also noticed that the bootROM is different on the 1.42DP machine: 4.6.0f2 versus 4.4.8f2 on my 1.25DP machine.
bottom line: from a DP 1.25, is it really worth it to go with the 1.42DP? What percentage of performance gain will I see, and if at all, can it be done? Money is not a problem for me, as I saw this processor and heatsink for less than 250 on ebay a few nights ago.
Thanks,
Nadav

Hi Carl,
Thanks for the reply. 13.6% doesn't really seem a whole lot in performance/speed gain, does it? Anyway, I did call a technician from colorado and he told me about 10-15 percent is all I would notice, and that for each 100mhz up to 500mhz, the speed and performance is really really miniscule, so as of right now I am now concentrating my efforts on getting just the copper heat sink as it has a cooling pump which should aid in lowering my processors down a bit further. Although, as I type this temp monitor reports the cpus running at 92.8 degrees fahrenheit. Now, another thing thats bothering me is the internet speed. My roommate has comcast high speed wireless - doesn't seem to be high speed though it is. Problem: I periodically lose connection or it slows down and gets sluggish.
I am using an airport extreme PCI card(802.11g). Its a Belkin FD57000 card which is similar in speed and strength to the airport extreme card by apple.
Is there a way to boost the wireless performance of a PCI wireless card, or better yet, boosting the performance of wireless internet at all? That seems to be the only bottleneck I am experiencing. His computer which is in the other room not too far from me is a PC running windows 2000 professional and he has a white wireless router.
periodically, I have to turn it off and turn it back on just to get the thing to speed up, but is the problem associated with my card or my mac? I don't think it is, but I was wondering if there is a way to boost speed performance of wireless service. Personally, I prefer wired since really its better and more secure + it NEVER EVER(at least when I had it at one time) dropped service at all.
Thanks Carl,
Nadav

Can I swap out my mechanical HDD for a Solid State?

Can I swap out my mechanical HDD (7200 RPM, 320Gb) for a solid state drive? If so, am I able to purchase such a drive, like the ones that come standard in Macbook Pros on the Apple site? Can I purchase an item like this from Apple?
If not, could someone point me in the right direction?
Also, on the same note, is it possible purchase replacement Mechanical HDD (like the one I already have) from Apple; if so, a link please?
Cheers!

You'll find everything you need here, swapping them is easy just get the right tools and take it slowly.
