• LaserJet M1536 printing and scanning Issues (cable network)

  Good,

  So I have a LaserJet M1536 I installed the drivers on my computer to WIndows 7 (64-bit). It worked fine for printing until last night and I can't for the life of me it works again.

  I have the computer plugged into the network, and it worked until I tried to scan a document. It would not work, and then after that nothing would print. The e-print on a mobile device will work but not from my windows machine. I tried to run the doctore scan and it says everything is working.

  I then uninstalled the drivers and I downloaded the latest version of the HP technical support.  Still doesn't solve it.

  After that, I have disabled the firewall on the computer (the windows firewall and the firewall that comes with my suite Norton anti-virus. Still no luck.

  I restarted the printer, my PC, my network (modem and router) several times.

  Is someone can you please help me solve my problem, because it is really holds my productivity and I spend a lot of time on this issue.

  What I am doing wrong? The only thing I have not tried is assign a static IP address to the printer.

  

  Thanks for letting me know TFroehlichIII.

  What type of router you use, or you use a server like the one mentioned post?

  When you add the printer port, must be a TCP/IP port.

  I have a few other things you can try.

  Power cycle the router, restart the computer, then on the printer.

  Check the IP address, to ensure that it is the same thing.

  Then run the Add Printer Wizard.

  You can always restore your computer to an earlier era where everything was working properly. It could be a Windows Update or a router that has caused this problem.

  For Windows 7 system restore.

  How to refresh, reset or restore your PC on Windows 8.

  If the problem persists, I recommend to call the HP Technical Support for assistance. They can remotely to your computer and see more of what's going on. Call the 800-474-6836.

• LAN/WAN design issues: redundant network core design and equipment

  Dear all,

  I have a growing network that has inherited the reliability and scalability issues:

  (Example from my existing network)

  

  We pop connected with us through lines of CF, that LSPS are connected to our CF traverse on persistent organic pollutants.

  Now, it is necessary to make the core of switching (switch with "?" mark) redundant

  because this is the point of concentration of all connections outside.

  I got an appointment in order to study new equipment (now it's just Catalyst 3560) for this network block.

  Unfortunately, the budget is pretty low.

  I have the following considerations:

  I think that the main problem is that most of the connections is L2 trunk links and it is difficult to prevent this.

  It seems that I need to duplicate all the links to LSP FC, pop and branches (this seems doable) and rely on STP! (this seems bad)

  with all of these links.

  Currently, I have two options for the basic block:

  1. two Catalyst 3750 have duplicated links. (CSW1 LSP1, CSW2-LSP1) and rely on STP

  2. a switch Catalyst 4500 series with two redundant supervisors (probably, they allow to buy if there are strong arguments) have reproduced links and rely on STP.

  These two options do not look good because I have to rely on STP with LSP.

  I would use redundancy features and L3 protocols, but do not know how to avoid trunks

  I have no experience with the material of fantasy as a Catalyst 4500/6500 series.

  Could someone please advice me alternatives for options of design and of the hardware and confirmation or withdrawal of my options.

  Also, I would be grateful if someone could help me find strong arguments for the acquisition of Catalyst 4500 series light up the core.

  Thank you much in advance.

  Best regards

  Max

  Hi Max,.

  in the diagram and description that you provided the switch, you need to replace is a dashboard device that works only for the moment, in L2

  If you plan to go L3 communications in this device, you should review your design to the whole of the network and also review/discuss with MS how that can be converted into L3 communications

  If you want to keep the same as L2 and introduce it into the device or devices for redundancy, I'd rather have two redundant devices of a redundant chassis that I mean pair of 3750 is more reliable chassis 4500 with equipment redundant as soup, UPE however its a reliable option as well and again for sure

  If you rely on STP for redundancy, what is the problem here? It is time of convergence or what is your concern?

  hope this helps

• HP OfficeJet 6700 - issues of networking after computers changed from cable wireless...

  We have changed our whole yesterday and left two computers (a Mac and a Windows 7 PC) be wireless to connect to the router.  The installation of the printer has not changed (it is set up wireless for everything).  The Mac has had no problem finding the printer and print as usual.  The PC was not able to print from.  It shows the printer as a faded option.  Print jobs that were sent in the print queue, but does not print.  I downloaded and used the doctor printing & scanning HP, including the wizard on the printer wireless, but have failed to get the connection works.  I appreciate any help you can offer.  Also, I apologize if I'm wrong at all since this is my first post and first visit to this forum.  Thank you!

  So if the Mac can see and print to the printer, which indicates that it is connected to your router OK.

  So, on the PC, go to start > Control Panel > devices and printers and delete the printer.

  Then, add the printer with this method:

  1. make sure the printer is on and connected to your network. Verify that you can access the printer's internal web page by accessing its IP address before continuing. Get his IP address for a network Test printed on the front of the printer.

  2. click on > start > Control Panel > devices & Printers.
  3. click on add a printer
  4. Select local printer
  5. Select create a new port and select Standard TCP/IP Port, and click Next.
  6. under device type, select TCP/IP Device. Under the name of host or IP address, enter the IP address of the printer. Click Next.
  7. Select Hewlett-Packard in the list of manufacturers and select and select your printer model. Click Next.
  If your printer model is not in the list, then select disk provided, browse the CD that came with your HP printer and select the first file begins with hp and ending with INF. click Open, then OK. Select your printer model. Click Next.
  8. If prompted, use the driver that is currently installed.
  9. He will ask the name of the printer - enter a new name or use the one existing. This will be the name of the printer that you select from other applications.
  10. we may ask you to share the printer. Choose No.
  11. the printing area of Test Page is displayed. Go ahead and print it out.
  12. click on finish.

• Issue of network 1415 CM

  Can the cm1415fnw use the ethernet network connection say 192.168.1.100 and also use the network on a different network wireless connection 192.168,30.100. allowing computers on each network to print to the printer?

  Hi-network,

  No, if you have the Ethernet cable is plugged in it will disable the wireless on this printer. Can't have the printer connected to two different networks simultaneously.

• Troubleshooting an issue of network ESXi

  I've done memory up gradation of a virtual machine and power, it works in a different ESXi in the same cluster, who do not have virtual machines.

  The virtual machine is not the ping requests, but able to access by using the console.

  However, the virtual machine is on the same switch distributed in the two ESXis.

  When I turned on in the old ESXi, it pings fine.

  No possible explanation?

  However, the virtual machine is on the same switch distributed in the two ESXis.

  In this case I would start checking the host's physical network connections and the physical switch settings, i.e. the tag/untagged, allowed VLAN...

• Issue of network design

  You want advice on which Setup is better in terms of network speed and configuration. That would provide the best performance among the following options:

  Multiple trunks in vDS using road based on the physical load of NIC

  vPort channel through several N2Ks in vDS using road based on IP Hash (I know that this is a requirement for Port channels)

  Or some other editing? I would like TO connect 2 x 10 GB straight in the N5Ks, but don't have the cards right now. These will be just for normal VMs on the side business of the House... no DMZ or something funky like that on the initial Setup.

  Thoughts?

  Thanks in advance.

  Unfortunately, the answer is not as simple as that. My gut response is "it depends."

  In most of the solutions that I have held, I have a requirement of customer care for a large number of machines virtual workstation 'type' to be deployed - a result is a lot of density VM on my guests. All virtual machines have only a NIC in the result, the way that handles vswitch that their movement would not benefit from the etherchannel for defined reasons application - I don't have multiple NICs to level VM to enjoy multiple NICs nationwide vSwitch, so I can't use multiple paths in an etherchannel link. No gain.

  So to answer your question directly with this type of scenario, no, there is no gain.

  Different scenario: I have a server VM. multiple NICs, stuck. Network cards present the vswitch. The vSwitch is on an etherchannel. It should work faster, no? The answer is not necessarily - it depends. Often, servile NIC bring several physical interfaces to a logical interface presented to the switch - therefore, a MAC address. Don't forget the LACP discussion? When you have defined "route based on source MAC hash", there isn't that one MAC - and LACP will assume only link. Hash of the IP? I've seen a few examples of what I call 'miracles' on the side of the machine virtual NIC, but for us, simple mortals who do not want to be network stacks re-writing all the time, what an interface.

  Once again, no gain. How to solve this problem? You could split the servile NIC and that they present multiple MAC addresses in this case (and it takes the server config to use this configuration in this way), or multiple IP addresses, or extreme measures. Books-the measures a little load balancing. Not the shot I would - I don't like not called late into the night to fix the unnecessarily complicated links.

  Moreover, one is easier simply apply a faster link. If we compare the economy of the whole of thinking necessary to solve an etherchannel (and remember, it is not a two-way entity by itself, you should pay attention to both ends) to what it would cost to slap in a 10 Gbps connection, I know which I take the road.

  Lots of shine of profound details in there, but I think that somewhere in the middle is the answer you're looking for. I hope this helps.

• Issue of network redundancy

  Hi guys,.

  Just a quick question/precision.

  On the ESX hosts in our environment, all hosts have 8 physical network interface cards.

  The way in which we have our network configuration is that the IP subnet that the Service Console runs on (10.9.8.X) is also our internal network IP subnet.

  The way I have my setup of the guests is with two physical network adapters on this network goes into the same virtual switch.  For the Service Console, the network adapters are configured as active / standby.  For the internal network, they are configured as active/active.

  What is the correct/preferred way to set this up not only for the Service Console redundancy, but also to have NIC teaming to achieve a greater bandwidth on our network inside?  Or should I try to use some of the other empty NIC ports to finish to remove the Service Console of this IP subnet?

  James

  It is good to have 8 ports.

  A good way to implement an ESX Server is as follows.

  3 ports for network of VM and the Service Console, put them on the same vSwitch and configure the vlan trunking.

  2 port for vMotion (preferabbly on a separate vlan or a network)

  3 ports for IP storage, iSCSI/NFS

  I would use teaming on each vSwitch (static LACP)

  I do not know what type of storage going you...  The above is a good and redundant installation.

• Introduction the issue of networking

  I'll put up small data center. have 2 ESX servers. each has 8 network cards. 6 connected for now...

  I setup networking in 2 different ways and try to understand completely having 1 vSwitch with everything attached to it and have 3 switches to separate different traffic. What am I winning or losing in both cases? See attachment

  Thanks in advance

  the fact of having everything on a vSwitch work? Yes. It is recommended? lol best practice design uses multiple vSwitches for different functions. Also do not forget that a good HA configuration will also be an additional service on your SAN vSwitch console port in the vlan San.

  you won't see a big boost to the speed of movement. traffic travels only a those ports at a time for a request. It's not as if you have 1 link of 8 GB of bandwidth, you only 8 links 1 GB of bandwidth. balancing techniques will tell what hose will be sent the request.

  I also noticed that you have your console for service on the same vlan as the traffic of your VM. best practice suggests that you must have from the VLANS separated.

  the suggestion above that I gave about 3 vSwitches overcomes single NIC, expansion slot of NIC, on the NETWORK adapter and the physical switch failure. EDIT* if you have stacked physical switches, or you have a link or 4507. 2 separate physical switches aren't best practices. but stacked switches will not work.

• 4 issue of NETWORK card configuration

  Hi all

  So now all of my ESX servers have 4 NETWORK cards and are all connected to the store shared via fiber connections.  My current setup is as such.

  pNic0 - & gt; vSwitch0 - & gt; Portgroup0 - & gt; (Service Console)

  pNic1 - & gt; vSwitch0 - & gt; Portgroup1 - & gt; (Vmkernal for Vmotion)

  pNic2 - & gt; vSwitch1 - & gt; Portgroup2 - & gt; (The Vm network - runoff of all VM group of port)

  pNic3 - & gt; vSwitch1 - & gt; Portgroup2 - & gt; (Same VM network as pNic2)

  It would be more benifical for redundancy and performance if I put it to the top in this way rather:

  pNic0 - & gt; vSwitch0 - & gt; Portgroup0 - & gt; (Service Console)

  pNic1 - & gt; vSwitch0 - & gt; Portgroup1 - & gt; (Vmkernal for Vmotion)

  pNic2 - & gt; vSwitch1 - & gt; Portgroup2 - & gt; (The Vm network)

  pNic3 - & gt; vSwitch1 - & gt; Portgroup3 - & gt; (The Vm network)

  and pNic0 configuration of failover for Teddy portgroup1 while pNIC1 is the failover of Teddy portgroup0, then leave 1 default port id base vswitch failover load balacning.

  Here's how we do are 4 NIC configurations

  vSwitch0:

  Service Console - vmnic0 (vmnic2 is a stanby)

  vMotion - vmnic2 (vmnic0 is a watch)

  vSwitch1:

  Machine Virtual Port Group - vmnic 1 and 4 (the two active)

  Load balancing based on the original virtual port code

• Photon: Dropped calls and network connectivity problems

  I bought my Photon August 18 and he was not long for me first to the problems with network connectivity.

  The phone displays signal on the phone, but when you try to call, send text messages or surf the web. Zilch.

  A soft reset works every time. I've had some experience with the issue of the "appeal of ghosts", but had no network connectivity so often that he was too much a problem. Restores the soft 3-4 per day.

  I took the phone to the Sprint store and they told me that my phone verified and were not hardware problems that may be found. I said at the time on the update of the software of MR5 and was anxious to see how the phone after the update.

  I received the update on Wednesday and the phone worked fine. No appeal of ghost, no network connectivity not problems, only dropped the call.

  Now, Friday morning, I lost network connectivity despite seeing the strength of the signal and had to perform a soft reset to regain connectivity. My wife and I bought this phone at the same time. She had many calls interrupted before the update and we both experienced after that update eventhough signal showing on the phone is at least two if not more bars.

  Is this a known issue? Is it going to be/CAN this be corrected by a software update? Is this phone a lemon and he'll remember?

  I LOVE this phone. I don't want to get rid of it, but...

  Seriously. It's a phone! Making calls should be the FIRST thing that is done right.

  Please, someone, Motorola, reassure me that this isn't a lemon and that network problems are going to be fixed. I CAN wait, but I don't want to get stuck with two phones for $200 that need to be pampered just to be usable.

  Thank you

  TC

  Yes, it turns out that be was a buggy phone. Two stores tested Sprint phone for reception of the signal and they said that it spent; but as said the technician in the second store, the tests they take place the phone in ideal conditions.

  The two stores I've visited, said they were ready to replace the phone, but my first visit came just before the MR5 update software while I was willing to wait to see if the update corrects the problem. It didn't, but the replacement of the second store phone works fine with upgrading to MR5 and really no problem.

  I'll go ahead and mark this question as a response, but if you experience the same problems of chance complete loss of all network connectivity (Sprint or otherwise), I recommend getting the phone replaced. It is a bad camera.

  Oh and the technician at the second store mentioned the network problems. It has been a problem for them, but the most telling proof of the issue of network is random dropped calls. So if from time to time, you lose a call under the conditions of good network signal, it's probably not your phone and Sprint. I have almost that many abandoned calls as of late, so it could have been the wrong phone I had that really amplified the problem... or... Sprint has got some of the bugs in our region.

  Thank you for looking in. I hope that your problems are as easy to solve as mine and I hope that you are still within your 30 days so that you get a new replacement.

  Best wishes

• How can I get my LaserJet on my network?

  If you are having trouble getting your LaserJet printer on the network, then this video will help get installed it and on the network.

  The video makes reference specifically to the LaserJet 1102 printer, but the process is the same for other consumer model LaserJet printers.

  This video is for Mac users.  This video is for a printer LaserJet 1217, but the process is the same for other LaserJet printers.

  EDIT

  I found these videos on the YouTube Channel of Support HP printer .

  I hope that these videos will provide the community with their issues of network installation on LaserJet printers.
