• Satellite M300 - works only one USB port on the right side

  Hello

  in the series of M, Toshiba M300 satellite (red), there is a port USB combo and something else, and also another USB port ordinary on the * left * side of the laptop. There is also a USB port on the * right * side.
  Currently, for some reason, on my right, the USB port works (in other words, the laptop detects) and my left side, where there are 2 USB ports, it does not work (in other words, it does not detect it) I have no idea how solve this problem.

  And what happens if you connect the external USB mouse?
  It work?

  Why not, you can test it with the new operating system preinstalled too.

• R.620 with two INTEL X 520 Dual Port 10 GB DA / SFP +.

  We have R620s running for our VMware ESXi environment. Currently, each server has an Intel x 520 with sfp + ports 10 GB (2) and (2) gig ethernet ports. Each server also has a Broadcom 4 gig ethernet card port. Can I exchange the Broadcom card on each server with a different Intel x 520, so that each server has ports sfp + 10 GB (4) and (4) gig ethernet ports?

  Thank you.

  Hello

  jmartinich

  Ports sfp + 10 GB Intel x 520 with (2) and (2), gig ethernet ports

  Which resembles the daughterboard X 520/I350 network. You have only a NDC slot in the system, only one of those can take place. I do not show a similar adapter PCIe version.

  If you have 2 PCIe 3 slot CPU configuration while you might add just another X 520 dual port. If you have a PCIe 2 connector configuration so I am not all ports that you are wanting to get a valid population.

  Thank you

  My Thunderbolt screen has only 1 thunderbolt port, how can I Garland with 1 single port?

  It has two ports Thunderbolt.  One is connected to the cable, the other is on the back of the screen.  If you can't find the Thunderbolt port, you will have the Mini DisplayPort in the screen version.  It has three USB ports on the back.  The Thunderbolt display has three USB ports, a FireWire port, an Ethernet port, and a Thunderbolt port on the back.

  (The Mini DisplayPort version cannot be connected in a string.)

• Only one speaker works on the bottom of the phone

  All the documentation that comes with the Turbo 2 and online documentation I've seen before buying indicate that there are two audio ports on the bottom of the phone, one on each side of the Verizon logo. However, only the side right (while facing the phone) actually works. The left speaker does not work. Verizon, which did not, I called and they put someone in support of Motorola on the line. The motorcycle rep says absolutely the two speakers should work and my phone is defective. They suggested that I return it as a guarantee of Exchange. I'm happy to do, but before I did I stopped by a verizon store and checked four phones they had on display. All four phones had the same "defect". So is - can anyone clarify if both speakers work on any Turbo 2 phones?

  I was also wondering with all these mixed news, but there's a tear down video on YouTube which shows clearly there is only one speaker. I hear only on the bottom right, that nothing about ports to the left on mine.

• Model a block synchronous dual-port RAM with LabVIEW FPGA

  This question caught my attention recently.

  I am trying to model a particular design element called "RAMB4_S8_S8" with the LabVIEW FPGA module. This element is a block synchronous dual-port RAM allowing simultaneous access to two ports independently from each other. That being said, a port can perform read/write operation to this RAM while at the same time, the other port might be able to do the same thing. There are two opportunities of possible port conflict, however. The first is when both ports are trying to write to the same memory cell. The other scenario is when a port writes in a cell memory while at the same time the other port reads from it. Other than that, everything should be a legitimate operation.

  In order to reproduce this I select memory block that is integrated into my FPGA target. An interface is configured to be the playback mode, and the other is set to write fashion. For the option of arbitration, I let the two interfaces to be "arbitrate if several applicants only. Then I got a compiler error when I tried to run my FPGA code for this model in a SCTL. The error message is something like "several objects to request access to a resource through a resource configured with option interface" arbitrate if several applicants only ", which is supported only in the single-cycle Timed loop if there is only a single applicant by interface.

  This error goes away if I replace the SCTL with a simple while loop, but not what I would like to implement. So I wonder if there is a better solution to this problem, or is it just the limitation of the LabVIEW FPGA module.

  Thank you.

  Yes, you can use a form of conduct to perform the operations you want in the generations clock cycles, but all the code is inside a single SCTL. Basically, read the first address and storing in a register in a single cycle and then read the second address in the second clock cycle. This would allow you to two readings of valid memory every clock cycle 2. I have included a crude extract to illustrate the concept. The case selectors are identical with address A being connected to the memory in the true case, B in the case of fake address. Your biggest model memory dual port will be intact, but it will operate at 1/2 rate.

  Take a look at the white paper that provides more details on the construction of memory:

  Data on a target FPGAS (FPGA Module)

  The ball on the memory block indicates that memory block double port cannot be applied in a configuration of reading, which is a double ROM. access read/write port must be imitated with custom code.

• How can I put the Windows XP firewall in a port configuration 'allow all' and only block some ports?

  Without going into the details of why I need to do this, I'm putting the firewall of Windows XP in one allow all the configuration of ports and only refuse some ports I have in a list.

  I train this script via the command-line batch with the netsh firewall add portopening command.  From what I've read, if enabled the firewall denies all traffic and only allows ports with exceptions, so through batch scripts, I opened all the 65 000 + ports TCP and UDP, essentially with the firewall turned on but in a configuration of "allow all the»  I don't deny the 100 or so ports to my list that I want blocked after they are all open.

  This strategy seems to work, but the problem I waited and I now see is that svchost.exe takes 50% of my CPU time, have to deal with constantly these firewall rules.

  "From what I've seen on Windows XP, there is no way to have the firewall ON, and in a configuration of" allow all the "" because the XP firewall may not have defined port ranges, they must be defined one by one.  It looks like Windows Vista or 7 would be much easier because the firewall has got a re vamp of advanced features.

  Does anyone have a suggestion on how to realize this "allow all", deny some' strategy?  I know it's a strange use of the Windows Firewall, so let's please jump in front of a 'why would you do this incredibly stupid thing?"messages.

  Also, if it was the wrong forum (or website) to post on for this kind of question, I'd appreciate a recommendation of a more appropriate forum.

• WAP4410N shows only one SSID

  I have a 4410N put in place on my network. I use 4 VLANS on my network which I use my default VLAN 1 as the VLAN 'public' that we use to give our clients WiFi for free. I would have two SSID visible from the access point, a non-secure and connected to VLAN 1, and another set with WPA2 and connected to our Office VLAN on which the various servers and resources are available. My preference is for the two SSID be visible, because it is not a problem of major security and as the only one IT, I have no time to set up each computer that uses the network with the SSID, but I will if I have to.

  I set up the 4410N with his first SSID using our public WiFi name and does not have any security on it. I went to the page VLAN and configure it to use both the default VLAN 1 VLAN, and VLANS for the first SSID. Then I I went back to the basic settings page and added a second SSID and chose "Enabled". I went to the Security page and left most things like default (Wireless insulation between SSID is enabled) and change the security settings for the Office of SSID for WPA2-Personal. Finally, I went to the page VLAN and is the VLAN 4.

  When I return to my computer or other wireless devices, I don't see the public SSID, not the office. I have on my computer (Win7 x 64) one 'Other network' option, but the intensity of the signal on this network is lower than that of the public SSID available. Also, if I try to connect using the name SSID of the office and the password I put, do not access.

  Am I totally wrong understand how multiple SSID is supposed to work? I'm trying a lot of assumptions here. Anyway, any help that can be provided would be great!

  PS I have no idea if this would affect it, but in the interest of all possible factors of the inscription, the 4410N is powered by PoE and the switch port it is connected to is set to 802. 1 q with a value of 1 to 4 according to the VLAN.

  * EDIT *.

  After the announcement, I discovered that in the status page wireless, two SSIDS are listed, but only one (the public SSID) has a listed MAC. I guess I should add a somewhere. Where do I do this, and what is a 'safe' MAC use will not conflict with what anyone?

  * EDIT *.

  Those who appear to be 3rd party and are not optical Intel.  Even Cisco SR optics do not work with this card.

  http://www.Intel.com/content/www/us/en/Ethernet-products/optics-cables/Ethernet-SFP-optics-brief.html

  Above link: "Note: other brands of optical modules SFP + will not work with the Intel® Ethernet Server Adapter X 520 series.»

  I recommend you get the specific ones screaming in the technical guide, that those who have been tested and work. (Intel SFP nde2-SFP-1WLR or nde2-SFP-1WSR).

• Cannot send/receive at full speed with Intel dual port 10 GIG 82599 ethernet in guest on ESXi 5.5 OS

  Me to consider whether or not it is possible to send/receive to 20 Gbps throughput with Intel 82599 dual port card within a guest VM on ESXi. I use to send and receive traffic PF_RING DNA of ntop. I have configured the dual-port card Direct IO mode to allow the guest VM have a direct access to the card. For the traffic generator, I use a metal machine naked with another dual port ethernet to generate traffic. The generator of nu metal machine and ESXi have their double ethernet port directly connected via SPF + cables.

  In the first experiment, the traffic generator generates 10 Gbps of traffic on port 1. The guest VM is able to capture packets at full speed without any loss of package even for 64 byte packets, which translates into 14mil PPS. I had then invited VM pass to 10 Gbps for the traffic generator, which currently receives. However, guest VM was able to generate about 7 Gbps of traffic regardless of package size. The CPU seems to be fine at around only 20% of load. I do not understand why the VM can receive at full speed but could not pass to the line rate.

  In the second experiment, the traffic generator generates 20 Gbps of traffic on ports 2. The guest VM unfortunately can only capture at the rate of 5 to 6 Gbps per port for a total of 10-12 Gbit / s. I have the receiving process listens on each port on a different processor. Then, I got VM generate 10 Gbit/s on each port. Unfortunately, could not reach 5 to 6 Gbps per port, regardless of package size.

  The naked metal machine is only an AMD 2.2 ghz machine low range to four hearts. It can send full line ate 10 Gbps for gpbs port 1 and 20 for 2 ports. The ESXi server is actually a much beefier machine with the quad core Intel Xeon 3.2 Ghz. There is a lot of memory and CPU on ESXi machine.

  5.5 runs the ESXi server. I have 1 comments running virtual machine running experience.

  I'm quite puzzled why there is no bottleneck even in Direct IO mode. Both CPU memory seem to be good. I wonder if there is any setting that I need to be playing with in ESXi. I appreciate all help. Thanks in advance.

  It turned out that I placed the network card in the pci slot 3 which is only x 4 routing. I moved it to 1 (x 8) slot. Now, I get full 20 GIG.

• I have 2 Mozilla Firefox on my desktop. They are both version 41.0.2 - in my installation and delete I find only one. How can I delete one of them?

  I tried to update to Mozilla Firefox and I had another icon on my desktop. Now, I have Mozilla Firefox 2 and they are both Version 41.0.2. They are both exactly the same thing when I open the. I see only one on my add/remove program location so I won't delete it because I could delete them both. Can you help me?

  You can remove one of the office shortcuts if both point to the same firefox.exe in the same Firefox program folder.
  You can keep the one with the correct version information where the other is an older version of Firefox.
  Note that Firefox 42 will come out next week (Tuesday).
