SG300-28P: System LED not on. everything else working.

Hi Everyone,
Nice to meet you all.
I received an used SG300-28P today and immediately I found its System LED never lits. I upgraded the firmware to the latests but did not make any difference. So far I have configured the switch for my environment and everything is working fine including VLAN, L3 routing and PoE works on all ports.
I am puzzled, not sure what's wrong with it. In the System Summary of the Web GUI it indicates the System LED is constantly on. But the physical one is just dead (never lits including boot)
I hope its just the LED itself, the switch is definately out of warranty. What diagnostics can I run myself to understand it?
Thanks,
Mark

Hello Siming,
If everything is working properly on the switch, then you shouldn't be worried about the system led. The system led itself is simply not working.
This is the information you need to know about the system led:
Off - If the system led is off, it means the switch is not powered on (which in your case is false, since you told us the switch is working as it should, so that means you have a faulty led)
Green - If the system led is green, it means the switch working normally. If the system led is green and it flashes constantly, it means the switch is using the factory default IP address (192.168.1.254) to access to the switch. If it is solid green, it means that the switch has either an IP assigned via DHCP, or statically by the administrator.
Amber - If the system led is amber, it means there is a problem with the switch
As you can see, you won't be able to get information about the system led when is green or amber, since it is not working.
I would suggest that you properly configure system logs on the switch, perform constantly backups to the running/startup configuration, and keep track of which IP address you are using to access the switch GUI/CLI, that way if you forget your IP address, or if there is a problem with the switch, you know where to find the correct information.
Please let us know if you have further questions.

HP Deskjet 2514 will not scan, everything else works

I have a Deskjet 2514 all-in-one.
The printing and copying services work just fine.
However, everytime I try to scan, the power button begins to blink.
I tried to print a test page and it printed some kind of error code page.
I've tried unplugging it, waiting and re-plugging. It is not in a surge protector, but in the wall.
Everyone in the house who uses this all-in-one use Windows 7.
I need to be able to scan, so please give me solutions I can use.
Thank You.

Safari pages are darkened and unresponsive. Internet is fine. Syncing with MacBook did not solve problem. Everything else works fine.

Safari pages are darkened and unresponsive. Internet works fine. Syncing to MacBook didn't help. Everything else works fine, including a different browser and apps that use the internet. Safari responds to searches and bookmark changes, but pages are not clickable. Help, please.

Have you tried a reset ? Press and hold both the sleep and home buttons for about 10 seconds, after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot. Also have you cleared the cache : Settings > Safari > Clear Cache (and Clear History). Also, if your equipment list is correct, you update to 4.3.3

This an IPOD I bought used. Everything else works fine. It syncs to my computer and plays my music but will not connect to the USB interface in my car. My wife's IPOD, which seems to be identical, works fine. Any ideas?

Then my last suggestion is to Reset it, while connected to the BMW Audio.
Toggle the Hold switch, make sure you dont see the red mark when you do the next step
Reset the iPod -> Press Menu and Center button simultaneously for about 10 secs or till the Apple Logo comes ON
Then release the buttons

ITunes, app store, iBooks store, etc won't load and I can't figure out why. I tried rebooting and it didn't help. Everything else works fine. Help please?

iTunes, app store , iBooks store, etc won't load and I don't know why. Everything else works fine, and I've rebooted it. The problem is still there and I know I have a good Internet connection. Help please?

Have you tried disconnecting and re-connecting to your network ?. And when you say rebooted do you mean a reset ? If not then try that : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
You could also try closing those apps completely. From the home screen (i.e. not with any of those apps 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the iTunes, App Store and iBooks apps to close them, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.

Can I get help with podcasts? When I try to open the podcasts, itunes crashes, says "itunes has detected a problem and must close", or the spanish equivalent since my xp is in spanish. everything else works fine, it even downloads podcasts and syncs.

The only other thing I can suggest is to use the Repair option for iTunes.
Download the iTunes programme (do not uninstall your current iTunes) and then "install" the new copy. At some stage you should see an option to "install" or "Repair". Take the Repair option.
Once you've done that, if you still have a problem, I don't know what else to suggest, except to search through the discussions to see if anyone else has had the problem and managed to fix it.

I just updated to windows 10 and I have no audio, everything else works fine

i have no Audio, sounds or volume afte the update/upgrade to Windows 10. This is NOT the case yesterday when I did not have Windows 10 updated/upgraded into my Sony Vaio Laptop. Everything else works fine, it's taking a usb logitech mouse among other things. My Audio jack will not function so earbuds will not do the trick. I have found a old PS3 usb headseat seems to work, following that logic a usb speaker set would do the same. If you have a HD Cable you can link your laptop to a HD TV and use the TV's speakers. What can I do to fix my audio problem?

Hi judedudemude!

Thank you guys,

My Iphone 4S cannot play music without headphone. Everything else works, such as alarm, siri, notifications, etc..., except music out loud. I tried everything, but there is no explanation on why it does this.

My Iphone 4S cannot play music without headphone. Everything else works, such as alarm, siri, notifications, etc..., except music out loud. I tried everything, but there is no explanation on why it does this. If siri and alarm work fine, it cant be a internal sound system problem, and it is just for music without headphones plugged in or any other sound system.

Hi shanny202.
Really strange problem you have there. I have a few questions though.
Please try again and try to make the phone as a new without restoringen with you iCloud-data or backup-data from iTunes. Maybe it is something wrong with the data (strange).
Anyway, i think you should call Apple Support or visit an Apple Store, don't forgot to make a Genius Bar reservation.

I'm experiencing a similar problem.
I have a MacBook Pro Late 2011. I was using Lion (not Mountain Lion) with CS3 with no problems. Recently I installed a new hard drive in my computer and used Time Machine to transfer all my files and settings (still with Lion; I did not try to open any Adobe applications at this point). Then I udpated to Mavericks. Upon trying to open one of the Adobe applications, it told me I needed to reinstall CS3. I inserted the original disc and followed the instructions on the ReadMe file. I went to Applications > Utilities > Adobe Installers > Add or Remove Adobe Creative Suite 3 Design Premium. I did a reinstall, and at the end, it said that some of the components failed to install (see screenshot):
I did a partial install (not all CS3 applications), so there could have been more errors than this if all applications were installed. The applications themselves appear to work fine, but when I try to run the updater, it tells me I have no internet connection.

Acrobat updater works just fine [after I install the manual updates till 9.2.0].
Can you tell me where to find these manual updates? I looked on this page:
http://www.adobe.com/support/downloads/collection.jsp?collID=1&platform=Macintosh
but I don't see 9.2.0 for any of the CS3 applications.
The CS3 that I purchased (Design Premium) came with Adobe Acrobat 8. I tried to manually install the 8.1.1 update. It said, "Please choose the copy of Adobe Acrobat Professional to update", but the application is grayed out (see below). I did not try to install any other manual updates, yet.
I'm not sure what to do here besides use my CS3 applications the way they are without updating them ever. (I would rather not subscribe to the Creative Cloud.) Any help will be appreciated. I might try doing a complete unintall followed by a fresh install.

HT4059 Can't update iPhone4S software 6.1.2 to 6.1.3, because there is unknown error 3198. What is that error? Everything else works, but the update.

Is there any explanation for the error 3195. I can't find reasonable answer.
Everything else works, but the new 6.1.3 has not updated, bevause the mysterious error 3198.

Thank you for attention, about the error code. It was 3195, but it is no longer problem, because I managed update iPhone by my homecomputer. The PC in my work wasn't "up to date". Case is closed.

You cannot connect to iCloud.com from an iOS device, you can only connect from a computer. You can access any of the data in your iCloud account from the appropriate apps on your device (mail, contacts, calendars etc)
