Nexus 9396PX Data centre switch not booting.

Nexus 9300 switches are not loading with code and getting the below error.
Loader> prompt and i tried with boot command and no luck.
Do we need crossover cable for netboot from tftp server?
Configured the IP setting in the nexus through Set command.
PC-------------Nexus9300(mgmt0) port.

Thanks Colin,
I was thinking towards a 6500
For a small setup with currently about 20 clients, and looking towards increasing that to about 50 in the next year, would a single / pair of 6500's be a suitable core.
Is there any benefit in setting up an MPLS core with routers etc, I have done it in labs but can't see how to scale it for a real world implementation.
I am thinking the VRF separation on the 6500 is going to be sufficient and forget MPLS?

Linksys switch not booting

I have a Linksys switch model SRW248G4P that is not booting. After connecting to the console, booting process stops imediately after loading the diagnostic image file. Is this switch toast? Anyone knows what is the warranty on this type of switch?

hi
Obviously the excellent support technicians at our Small Business Support Center, quickly determined that the product could not be fixed locally for a number of reasons.
My apologies that you have to go through the time involved with the replacement of your switch.
Next time you need a low cost Small Business switch, check out the rereshed SRW series. So many many new features, including Layer 3 switching, Green technology etc....enjoy

Cisco Nexus 5596 does not boots up after NX-OS upgrade 5.1.3.N1.1 to 6.0.2.N2.5 [CSCun66310]

Hello Friends,
Just want to save your precious time & effort, while doing Nexus 5596 upgrades so wanted to share some useful info which you can have a look prior to your upgrades of Cisco Nexus 5596 device.
I recently ran into trouble when upgarding one of datacenter switch Nexus 5596 does not boots up and after investigation from Cisco TAC it comes out to be Bug documented below.
https://tools.cisco.com/bugsearch/bug/CSCun66310/?reffering_site=dumpcr
My Upgrade path of device was : 5.1(3)N1(1)  to 6.0(2)N2(5).
Since this upgarde involves upgrade of Bios and Power sequensor, I was having some doubts to get this succesfully upgraded, But there was more twist involved in this upgrade which I came to know after contacting Cisco TAC for my died Nexus 5596 device and got info that if you have below impacted version in your Nexus 5596 device and you are planning to do Upgrade, then you migh RUN into this serious BUG aftre which device won't come up at all and only Option left is to replace with RMA device.

You can check hardware version using below command from your device.
5596# show sprom sup | inc H/W
H/W Version     : 1.1
So please be carefull when planning your Nexus 5596 upgrade and verify above things as this Bug is not present anywhere in Upgrade docuemntations unfortunately.
Hope this will help and save someone's precious Time.

Today "upgraded" our switch (N5k-C5596UP) to from 5.1(2)N1 to 7.0(5) and after reboot no life from the switch either. Even no console response. show sprom sup | inc H/W shows 1:0.
Only thing we could do is RMA the switch. So what must I do with these switches? Have still to do 3 of them.

IMac will not boot up. Need to transfer data iMac (2006) iMac (2009)

I have an iMac (built/sold late 2006 -400 Firewire) and an iMac (built/sold late 2009 - 800 Firewire).
I have connected computers with a 400 to 800 Firewire cable.
The old iMac will not boot to desktop. It was suggested to hold down the "T" key and then power up the iMac. This was done and the old iMac shows a "Y" shaped icon that appears to be a Firewire icon. The old iMac does not show up on the desktop of the new iMac.
I would like to transfer data from the old iMac to the newer one. Suggestions ?
Thanks.
old iMac OS 10.4.xx
new iMac OS 10.9.2

She's holding T down on the old computer.
Which is the way it has to be done. The old computer's hard drive will mount on the new computer.
To use FireWire target disk mode
Make sure that the target computer is turned off.
If you are using an Apple portable computer such as a PowerBook or MacBook as the target computer, plug in its AC power adapter.
Use a FireWire cable to connect the target computer to a host computer. The host computer can be powered on.
Start up the target computer and immediately press and hold down the T key until the FireWire icon appears. The hard disk of the target computer should become available to the host computer and will likely appear on desktop. (If the target computer is running Mac OS X v10.4 Tiger, you can also open System Preferences, choose Startup Disk, and click Target Disk Mode. Restart the computer and it will start up in Target Disk Mode.)
When you are finished copying files, locate the target computer's hard disk icon on the desktop of the host computer and drag it to the Trash or choose Eject (or Put Away) from the File menu.
Press the target computer's power button to turn it off.
Unplug the FireWire cable.
(my emphasis).
Excerpt from: http://support.apple.com/kb/ht1661
The terms are Target and Host. The old iMac is the Target, the new one is the Host.

I can not boot my MacBook Pro. How do I get and save the data that is not backed up??

I can not boot my MacBook Pro running on Lion 10.7.4. I pressed control, comment P and R keys and O got to the disk utility, then I tried to repair disk and it can not be repaired. I get a message that tells me to back up as much data as possible ?. But if I can not open the computer how can I save my data??
I have a back up until 2 weeks ago on time machine. but the work of the last 2 weeks is extremely important how can I get it??
If I use m time machine backup do I loose the additional data of the last two weeks!,
Please help.. It's a huge amount of work that I have done and can not loose it

If it were me, I'd get a new hard drive or SSD and put it in an external enclosure. Boot into the recovery partition, format the new drive (not the old one) and install the OS to it. Shut down the Mac, open it up, and swap the drives. You may be able to read your data from the old one externally if you're lucky. If you're very lucky you may be able to use Migration Assistant to move all your stuff to the new drive.
Look at ifixit.com for the exact procedure to get to the drive on your model. If it's a unibody it's pretty simple.

MDT 0xc0000098 The windows boot configuration data file does not contain a valid OS entry

hello,
i installed WDS+MDT for OS deployment. all was working fine.
Now i need our branch office to be able to deploy OS as well.
I installed a new Win 2008R2 server, and installed the WDS service on it.
When reading about this on the internet i saw i need, on the MDT at our main office, to make a link, under "Advanced Configuration" - "Linked Deployment Shares" to the new WDS server (I used this: http://www.balm.se/?p=115")
when doing so i entered the UNC path to the new server and then, on the created link, i right click and choose "Replicate now".
after doing so, i tried booting a laptop just to see if there is any impact, and now, I'm getting this error:
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. insert your windows installation disk and restart your computer
2. choose your language, and then click "Next"
3. Click "Repair your computer"
If you do not have this disc, contact your system administrator or computer manufacturer for assistance.
File: \Boot\BCD
Status: 0xc0000098
Info: The windows Boot Configuration Data file does not contain a valid OS entry.
I know that usually when I'm getting this message, it means that a previous MDT installation was started and did not finished correctly, and the are some [stuff] on the HD, so i do a partition erase and start over and all working fine.
Now it's not working. I tried several computer, even new ones, and NADA.
someone know the cause?
I know I read something, i don't remember where or how to find it, that when doing the steps I did, it alter\change some ini or xml, or something like this. is that true? any one know on what file do i need to look and see if something is misconfigured?
thanks a lot for your help

For a branch solution I would use DFS(R) rather than linked deploymentshares.
If there is infrastructure at the remote sites you could use the MDT environment at your main site, and then at each other site use an existing server or build a new server (VM is available). Create a Deploymentshare on each sever
and copy the contents of the MDT environment from the first site into this share. Next you will have to add the WDS service to each site's server. For WDS add the boot image. Of course as Keith noted ensure that you
have the same versions of MDT and the WAIK/ADK on all systems
You can use DFS to replicate to all of the other sites, but you will still have to create a deploymentshare, and install WDS at each site. So each site talks to its own WDS server you can use the DefaultGateway parameter instead -
[Settings]
Priority=Default, DefaultGateway
[Default]
SkipBDDWelcome=YES
[DefaultGateway]
192.168.10.1=Bergen
192.168.20.1=Oslo

DeployRoot=\\MDT-Bergen\DeploymentShare$
[Oslo]
DeployRoot=\\MDT-Oslo\DeploymentShare$

My macbook pro is not booting up.I haven't backed up my data .apple is offering me to replace the device . could you please help me on hoe do I back up my data

Please help me back my my data . My system is not booting up.There is some hardware issue.
Apple is ready to replace my device. But before that I need ro back up my data.

OK - now it's great that you got into the Recovery partition. When you hold down the option key, do you see your internal hard drive as well? If so, try booting into it and making sure that you set it as your start-up volume in System Preferences.
If you don't see your hard drive...
What you should do now is open Disk Utility. You want to see if it recognizes "Macintosh HD" (or whatever you've named your hard drive). If it does, select it and select "Verify Disk". It is likely that you will find some errors - if you do, select "Repair Disk". If the disk repairs successfully, you might want to just reboot and see if you can boot into your normal disk.
If there are no repairs needed after you verify your disk, try repairing permissions. You'll usually always have some permissions that need to be repaired. After this, try booting into your regular disk.
Good luck - call back - I'll be up for quite some time.

Phone will not boot, any hope to Recover Data?

Is there a way to get data off a phone that will not boot up?
My phone is constant rebooting. It reboots over and over and hangs on the eyeball screen, never getting to the home screen. (I plan to do a Factory Reset.)
I hadn't done a back up recently, and had been saving photos on the phone memory rather than the SD card (lesson learned.)
Is there any way to recover any of the data before doing a Factory Reset?
I am aware of the "Volume Down, Power button" start up to do the reset - is there anything there that will allow it to be connected to the computer to copy files off?
... By the way, I have started the phone using Volume Down / Power start up and selected "Recovery" and I get the icon of a phone with a red triangle with an "!" inside it, but my computer does not recognize the phone when it is plugged in via USB.
Thanks.

I regret to hear that Safe mode is not working correctly. Below I have provided the instruction just in case.

Data Recovery off of a drive that will not boot

I have a server which will not boot into windows, I really just need to grab a few files off of it, I have downloaded several types of software and of course there is a limit on how much it will restore then it wants you to pay, the size is about 52 gb's, I used to use WINPE, does anyone have a piece of software that is free that I can recover this data since I can not boot into windows?
This topic first appeared in the Spiceworks Community

Did you do this:
Repair the Hard Drive
Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. Select the external volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. Quit the installer to restart the computer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
See if this works to repair the drive.

Mac Pro will not boot, power light flashes once and then Mac switches off

One of our Mac Pro's will not boot. When pressing the power button the light will come on briefly and the Mac will just turn off again.
I have unplugged the power cable and held down the power button for 10 seconds but this did not help.
Any suggestions for me before I call up Apple?

Most indications from flashing power lights are telling you that there is not enough working memory to start up.

IMac will not boot into OSX after startup disk switch in control panel.!

I am having trouble with my son's iMac DV SE (graphite) running Classic and OSX (10.3.9). Typically, the computer runs in OS9 as the startup system because most of the kids' software we run is old and uses Classic. Over the weekend, I changed the startup disk to OSX in the control panels and restarted the computer so I could install some new software. The computer will not boot past the gray apple and progress indicator. I have tried resetting the PRAM, booting from the CD and restarting with the options key depressed to no avail. (Can't do a Safeboot either.) I was able to put the iMac into target mode and access the control panels via my laptop and restart in OS9. I thought I had resolved the issue causing the startup problem, but I was wrong. Now I can't get past the gray apple or access the hard disk through target mode (the iMac hard disk does not appear on the laptop's desktop). Is there a way to force the computer back into OS9 other than holding down the option key at startup? When I try this, I get the hard disk icon, but I can't move it off of OSX. Thanks in advance for any help.

Is there a way to force the computer back into OS9 other than holding down the option key at startup?
Holding down the OPTION key will only work if OS 9 is on a different partition than the OS X installation. If they are on the same partition, it won't work.
One way to get it back to OS 9 is to boot from the OS 9 or OS X installation disc. Then set the control panel, or preference pane, to boot from the OS 9 installed on the hard drive.
Another way is to boot from the OS 9 install disc and perform a clean install of OS 9. This will create a new OS 9 System folder and it will NOT touch any other files on the drive. KB 58176, Mac OS 8.5, Mac OS 9: Performing a Clean Installation

Complicated problem: Laggy Macbook Pro, now not booting

I am facing a very complicated issue with my unibody Early 2011 15" Macbook Pro (2.2 ghz core i7, 4gb 1333mhz ram, amd radeon 6750m, if you need hardware details).
I guess the issue started after my computer started to get laggy for no reason at all: it was never the GUI that lagged, but whenever I would perform some data-dependent tasks such as playing a video, or trying to open a big file. This lagging did coincide with some of my friends playing around with magnets around my computer (which may have possibly corrupted hard disk data).
After it got laggy, another major problem hit my MacBook, where I plugged in an old, broken USB into one of the ports by accident, and the computer suddenly shut it self off. The computer then seemed to have no power at all, with no response to pressing power button, or the battery indicator button. I feared the worst: that my logic board had been fried, so I immediately took my computer to the Apple Reseller. The technicians there said it was no problem at all, just that my motherboard had shut itself of in order to protect itself from a USB power shortage, and he unplugged and replugged this one small component on the logic board, which I am guessing is the Power Management Unit, and my computer miraculeously started booting.
So then, I get back home, and the laggy problem is still there. I just had to cope with the problem for a few days, until I go back to the Apple Reseller, but then suddenly, after a restart, the computer started not even booting. The grey apple icon would blink, and turn into a circle with a cross icon. Checked online, and this is apparently related to corrupted system files. This is where I began to suspect that the USB shut-off from few days ago, did more damage than the technicians thought: maybe related to the hard disk, or RAM.
But then again, it could have just been a coincidental corrupt hard disk from my actions, so I wiped/repartitioned my hard disk, and restored the OS and my files from a TIme Machine Backup. Again, the problem was still there, so I thought it might be to do with my backed up system files, so I did a fresh install of Lion.
The fresh install of Lion seemed to eliminate all lagging problems, but after I started copying my files and installing applications from Time Machine, the lagging problem gradually returned. So another question arose, was it a faulty hard disk, or a corrupt file or application that was making it laggy? To check if it was my hard disk, I did a zero-over erase of the entire disk with Disk Utility, and sure enough, the writing process failed in the middle.
After thinking I zeroed in on the problem, I replaced the hard disk in my Macbook Pro with another 750gb Toshiba SATA drive, and did a clean install of Lion. Once again, the laggy problem was gone, but just like the old hard disk, the laggy problem returned after I started copying files over and installing applications. Switching applications would take forever, and accessing folders on my hard disk would also be laggy. Playing videos was impossible, but the GUI (dock, spaces, etc) were all very responsive.
Now, I thought the problem is either with faulty RAM, or my hard disk reader is broken (since two hard disks, although the original one was faulty, both failed). I read online that the Apple Hardware Test (AHT) can help identify and pinpoint hardware problems, so I inserted the 2nd disk that came with my computer (Applications Install), and pressed D, but then nothing came up. After countless attempts, I maybe thought it was the wrong disk, so I inserted the 1st disk (OS Installer), and held D while booting, but still, AHT would not load.
After countless attempts at loading AHT, all of which led to me forcing shut down/holding power button after seeing the Apple logo, brings the problem to where I am at now: my Macbook does not boot into the login screen. After the Apple logo, and the spinner wheel have appeared, the screen turns white and the display becomes an infinite loop of switching from a gray color, to a white color.
This problem is frustrating me very much, because there are so many possible causes, and the problem persists even after reinstalling the OS, and even replacing the ard drive. The logic board shutoff could be the cause, but then again, the lagging problem started way before it happened. Somebody please tell me what is the problem, and what I should do? Thanks in advance.

Didn't know my magnets were strong enough to corrupt hard disks.
Yes, it's a method used to destroy data on a hard drive as it's recorded using magnetic fields, either "on" or "off" to represent the 1's and 0's that make up the basic building blocks of your data.
But, the magnet does not explain why the hard disk reported an error when being erased with zero-over option.
When the driver software has a problem reading the data on the drive, it assumes it's a bad sector, then maps it off and uses a spare. You likely ran out of spares.
I just tried zero-over erasing the second, good hard disk that replaced the original, but again, it fails. Is this a common problem with the zero erase option?
No.
or is it something to do with my hard disks, or some sort of damaged hardware in my computer?
Well this is drive #2 and it's new, and you get the same problem.
It's either something your doing, (like moving the hard drive/ computer while it's operating thus the heads are striking the platters) or it's a hardware defect, or perhaps the magnets did other damage we can't see, perhaps it's magnatized the computer and that's affecting the hard drive or electronics.
May be a loose or defective cable.
It's time for a hardware evaluation at this point.
