L2 switch replacement Mbps VS Gbps support & LAN cable......

In my current infrastructure, the network cable from desktops are connected to LAN jack which connects to patch panel in server room and then from patch panel to L2 switches which supports only 100mbps.
I will be replacing the L2 switches which supports 1000mbps. Now in order to get gbps throughput for all the desktops do I need to replace the cables at all the places? What about the connection from LAN jack to server patch panel?

Today, cabling plant expense, to upgrade to support gig, often is the most expensive component providing gig to the desktop.
In a similar situation, I have seen replacing switches with gig ports but not upgrading the cabling plant.  The reasoning was, the gig capable switches don't carry that much of a price premium and if plant as a whole or some parts are upgraded, you'll be able to support gig.  Parts of the cabling plant incapable of supporting gig were run at 100.  Further considerations included switches being replaced for other reasons, new features (e.g. 802.1x), and their expected lifetimes.
Users often don't see a huge improvement when moved to gig except when using Windows XP accessing servers that are across LFNs.  (NB: XP changes its default RWIN for 100 Mbps vs. gig.)

  • My Mac is a 21.5-inch Late 2009 with a 1 TB Seagate HD that must be replaced, according to Apple support, but they denied me that right because the serial is not part of the replacement program: any suggestions to get a plausible solution to this problem?

    I would want to know what are the criteria used by the people al espresslane support to deny the opportunity presented by the replacement program, given the situation that these 1 TB Seagate HD´s have had problems and certainly not only in the batch they accepted, but probable in other batches too.
    The second question is about the powerpc support that is lost when updating from Snow Leopard to Lion X: I can not read my medical application UPTODATE.
    I hope that there wil be some kind of support to help me solve that problem, this is my first petition actually.
    Now, I do not have access to my yahoo email, intermitent access to Apple home page, unpredictable access to Apple store and no access to iCloud in my iMac: when I try to access these web sites, the blue web address bar is interrupted and never goes to the end, no filling up the whole bar.
    I do not know what is the first problem, the Seagate HD or the Lion X, but my life is becoming a miserable one, not having the opportunity to enter in the raplacement program, losing the powerpc support because of the updating to Lion X, the necessity to buy Lion X again because it used to appear as a paid program, but not anymore, and finally having no access to my yahoo email, Apple home website and Apple store and no access at all to the iCloud: I am done.
    Chao, Elías.

    You can have Apple or a competent service shop replace the internal HD for a fee, unless you have AppleCare and the iMac is within its warranty period in which case it will cost nothing. If you must pay the cost will be approximately $350 US.
    PowerPC support is gone with Lion. You can install or retain Snow Leopard on another partition, and boot Snow Leopard as necessary.
    The inability to load web pages is a different problem, unless it is related to your failing hard disk.

  • LAN cable with MBP

    Hi every one, i have an EDIMAX wireless router and modem at home of a speed of 1.5 mbps ADSL at home, works ok with my MBP after some issues (i think every one knows what i'm talking about), after the last update it started to give me a hard time but after updating the last batch of APEX and AP it's ok now, my question is, how to secure my router by means of even if some one hooked there PCs to my router using LAN cables can't get access ? i'm using EDIMAX (AR-7064g+A). thanks in advance.

    The question of keeping the kids safe is not so much one of the network settings as the use of Parental Controls. This is another feature that can be accessed via the System Preferences panel. It needs a separate user account for your little ones (that will keep them away from your files as well) and then can be fine-tuned. Time-Limits in that panel seems to provide exactly what you want while Content has the access to the internet restrictions. Mind you, if they are bright (see below), they may well find a way past this eventually, so it is worth checking the logs from time to time.
    I guess from looking at your reply to Craig Brady, it is your kids who may be plugging in another computer (or accessing via your computer) using the LAN cables. As Craig says, there is not much that can be done with the setup you have now. Perhaps some more information about machine availability might be useful.

  • Replacement MBP arrived -- week 27?!?!?!

    I just received my replacement MBP today. It was shipped on Monday from Ranchero, California. This is my second replacement.
    I find it a bit strange that I've receved a Week 27, when most people here are getting Week 28 and 29 units right now. A quick search revealed that people were receiving Week 27 units at the beginning of July. I'm a bit mystified by this.
    What gives?
    Oh, and the whine is worse than my previous two MBPs. I'm not yet sure what else is wrong, though there is the same light slight leak at the bottom of my screen as the last one -- perhaps every MBP has this?

    Your replacement came out of a warehouse not off the assembly line.

  • IMac slows down wifi/LAN cable connection

    Hello,
    I came across a quiet unique and annoying problem, that I have not seen being discussed so far.
    I spend the last 3 weeks trying to solve my internet/wifi connection following all kinds of posts here.
    Problem: Wifi/Lan internet connection is slow (less than 0.8mbit/s)
    Problem only appears when I login with an iMac via wifi OR lag cable
    iMac, 2011 27`` Mac OS 10.7.5
    Background:
    I have a 20mbit/s internet connection with my provider. works fine on iPad, iPhone, appleTV HTC one mini, etc… BUT as soon, as I login with my iMac, the internet connection slows down to less than 1 mbit/s
    I have tried following solutions:
    - live box (router) was exchanged and is brand new
    - security settings on router changes (wpa2 etc)
    - all channels on router tested from 1-13
    - keychain saved passwords for Wifi and router deleted, PRAM reset
    - renewed lease of connected devices (no IP conflict)
    - shut down wifi on iMac - connection with all devices great, as soon as i switch wifi on, all devices lose their high speed connection and go down to less than 1mbit/s
    - connected iMac via LAN cable: same problem, all speed is lost
    - iMac is not in the network - speed is great
    - connected iMac via time capsule wifi, same problem. connected iMac via netgear extender, same problem
    also, if I open network preferences and start the "assist me" app and run diagnostics, all dots are green except the ISP and server, bit most of the time they switch to green immediately, but connection is still slow.
    Reception bar is on "3", so signal strength is no problem, and I´d like to emphasize that this is also happening on LAN cable. and again, if the iMac is disconnected from wifi AND / OR LAN, all other devices work fine.
    Would love to hear your thoughts!
    Thanks!

    Although I have been on Mac OS for a while now, I have never had to troubleshoot faulty network in the mac itself.
    OSX does apparently have a safe mode boot..
    OS X: What is Safe Boot, Safe Mode?
    Try that.. as that gives you the same thing as windows with all the extras left out, so you get a basic operating system only and you can see if the problem still exists.. if it does.. I would simply bite the bullet.. wipe the Mac.. reinstall the OS and then carefully reinstall your applications from original disks/downloads and move your operating files back .. but start a different user on the computer and copy back the min you need to get working again.
    If the problem still happens even in safe mode boot then do a hardware test.. because it is possible something has actually failed at the hardware level.

  • I want to force lan cable plugin during login process on 802.1x computer only weird client

    Hi
    I Configured Wired and computer only  802.1x authentications on all my switch and client on my network  ,It works without any problem .
    I have user logon script to change local administrator password each time they log on ,I recently find out they boot with light cd and change the administrator password and unplug the lan cable boot the system and login with new administrator password after
    that they plug lan cable , as they computer account is valid in active directory they are authorized and access the LAN .
    they bypass some group policy by this way,
    how can I force 802.1x wired client computer to plug lan cable during boot and login process in order to prevent bypass user login group policy  ?
    I want to force lan cable plugin during login process on 802.1x computer only weird client?
    Rigards

    Hello,
    you can disable CD/USB with GPO settings to prevent the use from it.
    And for the change from the local admin password you should consider that the CEO of the company should make clear policies so users can legally be punished if they don't work with the company rules.
    You can manage lot of settings with scripts etc. BUT there is a time where the CEO is responsible about rules.

  • Hi, I'm thinking of buying the Airport Express or Extreme for my school dormitory, would i need to plug them into the already existing school internet via LAN cable or do the products just work by themselves?

    Hi, I'm thinking of buying the Airport Express or Extreme for my school dormitory, would i need to plug them into the already existing school internet via LAN cable or do the products just work by themselves?

    Welcome to Apple Support Communities
    AirPort stations aren't modems, so they have to be connected to the modem you are already using. The AirPort Extreme and Express have a WAN port, where you have to plug an Ethernet cable that has to be connected to the modem.
    After doing this, you can set up the AirPort station by using AirPort Utility. If you have Windows, download AirPort Utility from the Apple website > http://support.apple.com/kb/dl1547

  • WAN/LAN cables

    This is more or a just curious question.  The other night we were having Internet issues.  They ended up sending us out a new router.  The next day it was all fine, so I'm thinking it might not have been a router problem.  
    Anyway the new one came and I was just looking over the installation book and realized that we have a yellow (LAN) cable from the phone jack to the WAN port on the router.   I switched it but it has probably been like that for years.  I can't imagine we switched it, although a few years ago we had router trouble, so maybe we did by accident.
    my question is just will this make a difference in hoe things run?  We weren't  having trouble before, so just curious.
    thanks

    I switched the yellow cable (the book says this is for the LAN port)  With the white cable (for the WAN port).   So we have the white cable going from the phone jack to the WAN port.   We only have a laptop, so we never have a computer hooked to the router anymore.
    What exactly is the "phone jack" connected to?
    Typically a fios router is connected to the ONT via coax though it is possible to ask for an ethernet connection in which case the ONT will be connected to the router via an ethernet cable which has 4 pairs in it - i.e.8 wires.  If this is run thru building wiring it will be a cat5 or cat6 cable that will terminate at both ends in a rj45 jack that has 8 connectors that will be wired in a specific crossover pattern. 
    A phone jack is typically wired using cat3 cable that normally are terminated in rj11 connectors straight through.
    As your yellow and white cables both fit the socket I would assume they are exactly the same using rj45 connectors - you can check this by looking at the cable where the wiring category will be stamped on it..  If you are having issues I would suspect the in house wiring but the only way to test that run is by using an ethernet port/cable tester.  There are many of them out there, not particularly cheap, I use a TS031A multi quick check from Black Box

  • Equium A60 Laptop crashes/blue screen when LAN Cable is in?

    Hi all,
    I have a Toshiba Equium A60 Laptop now for under a year.
    I am running WinXp Sp2
    Yesterday, my laptop started to crash flashing a blue screen (No time to see what it says as computer Restarts too quickly).
    I found that it only seems to crash when the LAN Cable is plugged ine.g. If I start the Laptop it will start-up as usual but when it starts to communicate with the network/router (as I can see by watching the little blue Screens in the Task Bar Bottom right) it Crashes. Ive tried a different port on the router but no luck.
    My Network card is: Realtek RTL8139/810x Family Fast Ethernet NIC
    It runs ok in Safe mode and doesnt crash.
    I updated the Driver but and it still does the same.
    I then decided to restore my Laptop back to Day One/Factory Default via the Toshiba Recovery DVD.
    When restored it worked fine all day (had internet access via the network) until I clicked: Set up a home or small office network in the control panel. It crashed again the same way. Now it will continually crash as above.
    Could this be a problem with my cable?
    Please help..Any ideas?
    Thanks loads,
    Shay

    Hi Shay,
    The blue screen of death (BSoD) can be a particularly annoying problem because it can be very tricky to trace the source of the crashes.
    Read http://en.wikipedia.org/wiki/Blue_screen_of_death for some more information on it.
    Common causes are ...
    - faulty hardware (could be the network card, or ram, or hard drive)
    - bad device drivers
    - overheating
    - corrupted software/operating system
    As you said that you've used the recovery DVD and the problem still persists, this says to me that it is a hardware issue (as long as image loaded on with no errors and DVD is in good condition).
    Easy things you could try are ...
    - changing the network cable (unlikely the problem but always worth a try)
    - checking the network card port for debris/damage
    - reseat the ram/hard drive
    - load on an operating system from scratch, if you have it (not using recovery DVD)
    If none of these work and the laptop is under warranty, get the motherboard/network card replaced.
    If not under warranty, try the debugging tool for Windows ... http://www.microsoft.com/whdc/devtools/debugging/default.mspx
    Good luck!

  • FM2-A55M-E33 won't boot if LAN cable fitted, black screen with 99 in rh corner

    Just bought a new Zoostorm 7872-1212/A computer, which has the MSI FM2-A55M-E33 motherboard.
    I installed and registered Windows 7, and download all updates etc without any problems last night.
    Started it up this morning, and it didn't post.
    All I had was a black screen, with 99 in the bottom right corner.
    Switched off, then tried again, still no joy.
    Removed all cables, re-fitted just mouse, keyboard and monitor, and it started.
    Powered of and refitted LAN cable.
    Powered on - black screen and 99.
    Powered off, bought new LAN cable, fitted it into another port on my router, powered up, black screen and 99.
    Thinking it's a BIOS setting, opened BIOS
    Set Sata drive as 1st drive, DVD as 2nd and disabled all other drives
    Set wake up events to BIOS, RTC disabled, all other events on
    Saved and powered of
    Started up, and still back screen and 99
    Anybody got thoughts?

    Thanks

    Hi,
    Based on its specs, it ONLY has USB connection and no slot for a NIC therefore you can use USB wireless print server to connect it wirelessly.
    Here are some of them:
         USB Wireless Print Servers
    Instructions and driver should come with the box.

  • Connecting MacBook Air to LAN cable?

    Hi
    Currently sitting in Singapore in a serviced apt that does not allow me to connect wirelessly to the internet. I have to connect a LAN cable to a laptop... How do I connect one to a MacBook Air?
    TIA

    Hi,
    Just head over to Wheelock Place on Orchard Road at the Apple Center (2nd Floor, I think) and ask for the USB to Ethernet adapter.
    That should let you plug in your Air to your LAN cable.
    The other thing you can do is get an Airport Express (from the same place). Just plug your LAN cable into it, configure it, and you've got wireless - easy!
    Hope that helps.
