• Tecra A2 - what is the difference between the cooling modules Tecra A8?

  Hello

  I have Tecra A2 and my fan is almost 'dead '. So I think to buy a new one.

  And here my question:
  "What are the differences between Fans (P000401740) A2 and A8 (P000463770) for example?"

  Because despite the construction of the "rotor" as well as details of construction of the case they seem to be exactly the same.
  If I buy this A8, it would work with my laptop?

  Kind regards
  Christopher

  Hello

  I m not very well what s the difference between these two modules of cooling but the fact is that the motherboards are just different and I doubt that a cooling module that was not designed specifically for the Tecra A2 series would correspond with A2 motherboard and case.

  That's why I recommend buying a cooling module which has been designed especially for this series!
  I think you can order the Toshiba ASP.

• Problem with a SIP Trunk between VCS and CUCM

  Hello world

  I created a SIP Trunk between control VCS (X7.1) and a CUCM 8.6.

  I followed this Cisco_VCS_Cisco_Unified_Communications_Manager_Deployment_Guide_CUCM_6-1_7_8_and_X7 - 0.pdf deployment guide.

  The trunk is in place, but I have the following problem: I can ring since an EX90 recorded on the VCS for a registered on the CUCM 9951 but when I take the call, I have a busy signals (audio and video). When I on the EX90 9951 ring, I have the following message on VC: can not reach the contact.

  I have a 503 service unavailable status on the call history and "call rejected" on the event log.

  My transformation is OK and the call is sent to my neighbor CUCM zone

  You have an idea to solve this problem?

  Thanks for your help

  Best regards

  Hello

  Yes, it's true! It seems at first glance a problem with codec negotiation when I see the reason 47 code.

  in any case set the region to G.711 trunk phone in case if you have different device pool and the trunk region and ip-phones.

  make G.711 end to end and test again.

  Thank you

• Trunk between SRW2048

  Hi all, I need to put a trunk between two SRW2048 connected via a fiber link, in order to leave a vlan to share between them.  My configuration is: switch A: - default untagged VLAN 1 - 10 of VLAN ID custom, named "wifi" - port 47-online fiber, defined as 'trunk', the two Vlan 1 and 10 are joined with the trunk - port 11: I want that he the VLAN 10, in order to see the 11 switch switch B: - by default without tag VLAN 1 - port custom VLAN ID 10 named "wifi" - port 48-online fiber, defined as 'trunk', the two Vlan 1 and 10 are joined with the trunk - port 11: I want the VLAN 10, to see the way 11 switch has tried to set the two port 11 mode "general", tag, joined only in VLAN 10, but I could not bind on the optical fiber. I tried many configurations for the two port 11, but they does not work. I think the 48 and 47 of fiber ports configurations are ok.  I hope you can help me thank you Alessandro Note:-yesterday I updated both firmwares to 1.2.2d; After that, I have an error in recording 'VLAN of Ports' setting on both switches. I check all the parameters. They seems ok, but this page (and only this) gives this error: line = 1 Type = unknown value = null value error diagnosis = may be lack of parameters (join1) in the page.  -I turned the 'enable 802. 1 x' flag on 'Security' => "' 802.1 x Settings"-I'm not using GVRP; " When I join the port to VLAN it gives me an error 'web' on Internet Explorer version 6 and 8, and I'm not able to reach the ports of vlan. On the other hand, I see the VLAN custom between switches only if I attach somethings to 11 ports (I use a dhcp server on one port and dhcp on another client).

  Only, I was struggling with today myself. That's what I had to do to get the VLAN on the trunk ports between SRW2048 and a SLM2024. Make the port numbers to the top, but you get the idea.

  SRW2048

  1-12 of Harbour = VLAN 1

  13-15 = port 3 VLAN, unidentified, mode = generally accept the type of weft = all, pvid 3

  40-43 = 2 port VLAN, unidentified, mode = generally accept the type of weft = all, pvid 2

  Port 47/48 = VLAN1, 2, 3 VLAN Trunk port = port should be vlan1, 2, 3 has joined to make you think it's the tag for 2.3 (check it, I'm 100% I added the and when I checked once again, they were gone.) "I think that changes to other environments will remove them?)

  SLM2024

  1-10 = VLAN 1

  14 = 3 VLAN, unidentified, mode = generally accept the type of weft = all, pvid 3

  16-18 = 2 VLANS, unidentified, mode = generally accept the frame type = alll, pvid 2

  12 (Trunk port) Add VLAN 1,2,3 with 2.3 tagged port

  Setup like that I could get access to all three VLANS on the trunk.

• VLAN Trunking between 6248 and 2848

  Hello

  I have a Powerconnect 6248 switch connected to a 2848 and I try to get a VLAN on the 2848.

  VLAN working and properly receive DHCP addresses, traffic lanes and DNS runs on the 6248.

  The Protocol DHCP, DNS server is connected to port 1 on the 6248.

  When I create a Trunk port on 3 the 6248 Port, allow all VLANS through it, creating a trunk on port 1 of the 2848 on VLAN10 and try to plug in devices inside, they can see all other devices connected to the L3 switch.

  The two switches are running the latest firmware and the L3 on his own works as expected. I can't get any kind of circuits working at L2, tried with normal cable and crossover switch.

  Here is the config of the L3 6248. Switch 2848 L2 has a blank canvas with 10 VLANS created on ports 1,2,3,4 with port 1 as the trunk port installation.

  Any ideas pleeease? Anyone? It drives me crazy.

  After turning off spanning tree on the 2848, all works now.

  VLAN, trunking everything.

  Thanks for the help! :)

  I hope that if someone else can use what it took me ages to develop. I plugged on Netgear switches etc and they seem to work.

  The issue was going on between the dell 6248 and 2848, Spanning tree is enabled on the default 2848. If I was going to the Netgear via the 6248, then at the 2848 switches worked.

  My config on the l3 also works very well if someone would use :)

• Vlan trunk between switches traffic encryption

  Hello

  Can someone guide me to some documents and other resources on how to encrypt the traffic between 2 switches. The switchces will be connected with fiber and use the marking dot-1 q. And I wan't to encrypt all traffic to shared resources.

  I was thinking about L2TP, but I have not found a good description on how to implement this. I have two 3750 switches, I thought I could use.

  Thank you for any input,

  Hello

  Thanks for the reply. I had a look at effect and it seems good. I would have liked to use something P2P but also limit the amount of MAC addresses on the "wire". But let me first give you an understanding of the task:

  We have two sites, linked by fiber, and we want to create a trunk VLAN everywhere and to expand the broadcast domains to you another site.

  The carrier FOOL, has a limitation on the number of MAC addresses, they allow the service to fiber, 100.

  We also encrypt the datatraversing this connectivity.

  MACsec wuold work 100% exept the source and dstination MAC addresses are still sent (at least according to https://docs.google.com/viewer?a=v&q=cache:LEf2qOmYZyYJ:www.ieee802.org/1/files/public/docs2011/bn-hutchison-macsec-sample-packets-0511.pdf+&hl=en&gl=za&pid=bl&srcid=ADGEESgmAHXpDOY0RBAE-Rv1HDpu_C_gkeSPN4cv6NGgyP0M1aXVu0UqzCfxo8t_P41ep6J37k4OLKnjfp1M9hoTDHxY22WGz2h7yB7YRLyPvRUbGS8TICzvEMlG92xqbhy6RWFugmnj&sig=AHIEtbTfu0LQIJejdYidE6yzq4lpPifxjQ
  )

  And who tempt me to eat in the limit of MAC 100.

  Ridiculous I know, but we are looking for an out-of-the-norm plan...

• Setting up QoS on SGE2010 to support VoIP trunks between PBX

  People, I'm stumped on how to configure QoS on my SGE2010 in support of my Toshiba CIX PBX VoIP trunks.  The infrastructure is simple:

  PBX (1)<==>SGE2010 (1)<==>SGE2010 (2)<==>SGE2010 (3)<==>PBX (2)

  where PBX (1) and PBX (2) are connected by three SGE2010 which are resources shared via fiber between the buildings.  I have not combined VoIP and are on their own VIRTUAL local area network switch.  All the rest was child's play in these switches but I have no experience with QoS and does not help the Administrator's guide.

  Jim

  Hi Jim,.

  The QoS of basic service should be everything you need for the switch. QoS works for traffic of penetration only. Basic behavior dictates QoS, if you upstream assigned QoS, the switch will approve the values as is. If there is no QoS upstream, the traffic of penetration will be marked according to how the traffic is classified. All output of the switchport traffic will not be noticed.

  On a dish network, 1 vlan, the default CoS value untagged 0, what is relevant for the packages. You can change these values from 1 to 7 for the traffic untagged. That reference the charts CoS for values of 1 through 7 in average.

  Strict priority for QoS queue will depend on how the traffic is marked. With strict priority, the highest value traffic will be allocated first on the output port. So you should drop.

  The part that most have problems with the DSCP values. These are defined on the DSCP to queue. You will notice a queue next to a DSCP brand. This traffic is ranked on that contains the package. Voice traffic typically DSCP 46, which by default has a line higher, I think that 3 by default. The switch will put the DSCP value for the traffic of penetration or trust the brand of penetration. But it will not note traffic out.

  I hope that clarifies a bit your request.

• VMPlayer between conflicting WWAN module on the HP Mini netbooks - how to climb as bug?

  On a HP Mini 5101 netbook, integrated WWAN module (Qualcomm - module high speed Mobile HP un2400) does not connect when the VMPlayer is installed.  The player has no need to run, only to be installed.  If the player is uninstalled, the WWAN module runs.  Bluetooth/WLAN modules are not affected.

  Not done that for geek factor, but to run a virtual machine of our CMDB application on netbook in case of loss of access to the data center and DR site.

  LiveChat HP helped but concluded because a third-party application conflict with the Qualcomm WWAN module, is the problem of third parties.  We stopped process/services but could not get around.

  I've seen a few similar reports on google with laptops HP and WWAN.

  The environment is Windows 7.  Latest drivers WWAN, VMWare Player.  The symptoms are HP Connection Manager is running, but if the on option comes with the message 'select supplier '.  Once you try to connect with HP Connection manager PC does not (except with power hard off).

  How I climb this VM as a bug between the reading software and WWAN module.

  Thank you

  There is a new Version of the HP Connection Manager (V.3.1.3.11), which solves the problems. The network card is also usable in a virtual machine with a NAT configuration...

• Has anyone set up a trunk between switches PowerConnect 2716 and Intellinet 523554?

  I have a client who has three switches Intellinet 523554 in the core switches and various on the edge, including a PowerConnect 2716 switch. The firewall is a Sonicwall, which is plugged into one of the Intellinet switches, and there are three new SonicPoints that plug in the PowerConnect switch. To the best of my knowledge, even if X 0 (LAN) and X 2 (WLAN) are related to the SonicWall, I need to keep these separate networks. If I plug them both in the VLAN 1, network crashes (I presume due to a storm of broadcasting). On all switches, I created 2 VLANS, left 1 VLAN not identified and configured the appropriate access and if necessary junction ports. Two types of switches use the web-based configuration and it is just not a lot of parameters to be set. VLAN 1 traffic goes OK on the trunk, but VLAN 2 does not work. I'm not familiar with the configuration of the Intellinet switches, so I sent an email into their support. Unfortunately, for the chutes, that's what the rest of the world calls aggregation of links, so I have no help from them yet. I am quite confident that the configuration is as good as it can get.

  Has anyone else tried this and been successful? Any thoughts? The PowerConnect switch runs 1.0.1.07 firmware. Thank you

  The marking of VLAN is the feature you're looking for, 802. q. 1, Page 10 of the user guide describes in detail the configuration of VLANS on switches Intellinet.

• How to switch a microphone directly between enhanced and not improved?

  Calls between Microphone.getMicrophone () and Microphone.getEnhancedMicrophone () on the same mixing unit apparently does not work very well.  Choose the following code:

  " < = xmlns:fx s:Application ' http://ns.Adobe.com/MXML/2009 "

  xmlns:s = "library://ns.adobe.com/flex/spark".

  You will be able to hear you speak at first, but as soon as you click on the application, you will no longer be able to hear your voice.  I saw this sort of thing in other scenarios.

  To make a long story short, if you call getEnhancedMicrophone() for a device, then try to call getMicrophone() for the same device, the device stops providing any audio input.  The same is true vice versa.  However if you call getEnhancedMicrophone() for one device, then getMicrophone() for a different device, and then return to the first and call getMicrophone() for it, the device will work just fine.

  Why?  Is it possible to just pass parameters improved and unimproved for the same device, without reaching out to an independent device?  Thank you!

  On your reference to Microphone, you have these constants that you can assign your options:

  http://help.Adobe.com/en_US/FlashPlatform/reference/ActionScript/3/Flash/Media/MicrophoneE nhancedMode.html

  As you can see, MicrophoneEnhancedMode.OFF disables the extended mode. You must set your microphone .blog property equal to disable references improved, or use one of the other relevant options to enable it. Therefore, you should always use improved as long as you can turn on or off.

• 802 1 q trunk between ESX server and router Cisco

  Hello team.

  I want to create 3 VLANs on my server ESXi, each with 2 VMS and these VLAN transported by an external Cisco "router on a stick", that is to say router with a configured ethernet wth 3 subinterfaces, each of them for each of VLAN (IP subnets) inside the ESXi server.

  I built the following image to explain my purpose. First it is possible to implement on ESXi? I guess it is.

  Advice will be greatly appreciated.

  Best regards, Rogelio ([email protected])

  

  It will work very well. Ive done a similar thing in the past, but rather than use sub interfaces I used Lass rather on a layer 3 switch.

• Variation of thermal EMF of the PXI-2530 modules

  This message/question is a companion of my the most recent message in another thread.

  In addition to watching some resistance higher than expected that affected current measurements using modules PXI-2530 multiplexer 4W topology, I saw systematic variation in track-to-track blood pressure measurements. Tensions would increase gradually through the 16 channels in a configuration by measuring the voltage at the terminals a resistor 1.5 kOhm with 0.5 au crossing (75 uV). I've identified that the thermal EMF of the reed in the PXI2530 module switches is on the same order of magnitude of these measures and set out to quantify the differences EMF thermal track-to-track between my three modules.

  Test method: I have a TB-50 which is configured to mux the signals of tension for a DMM. I connected each of the four DB-50 one cable of 176 pins to this block and collected with a PXI-4071 pressure readings set to 7.5 digits precision in the range of 100 mV and > 10 GOhm impedance. For most channels, it took several minutes for the voltage stabilize - or at least appear that it was to stabilize.

  I enclose three graphs. Note that the vertical scale is the same on each.

  Data that triggered this survey was collected with MUX1, via connector P2 to voltage. The magnitude was not quite the same-probably related to the phenomenon of stabilization time, but obviously the worst group of channels three multiplexer modules.

  The three modules were all bought at the same time (about 2 years ago), but had only limited its use in the first year or more. The three now have various 'mileage' based on my use. But MUX1 clearly behaves differently two other modules. The

  I changed my test conditions to spend 0.5 au via a higher resistance to thermal EMF less important. The PXI-2530 sheets indicate that thermal EMF must be less than 50 uV. In most of my measurements, it is. But not for MUX1!

  Any thoughts?

  Thank you

  Jeff

  Hi Jeff,

  You can check that all the three modules are PXI-2530, not PXI-2530 b (while, as the PXI-2530 b parts slightly higher thermal emf)?

  Specification of emf thermal 50uV of the PXI-2530 is a typical value, is not a guarantee of spec.  See a few channels higher than the spec is not a cause for alarm, but it shows that we must take account of this in our measurement error.  Note that the industry standard for the technical measure thermal emf is to close the relay, wait a few minutes and then take a measure of tension.  For example, if you scan through a switch faster than a relay per minute or so, the thermal emf will be less predictable and stable.  A single module performs worse at these low voltages is not indicative that this module is a failure, etc. the module is fine.  Unfortunately, the reed relays have more emf thermal relay of the armature, mainly because of the many layers of metal in a Reed compared to a frame (each metal junction is a source of emf if these metals are not the same).

  Thermal EMF is proportional to the temperature, it may be interesting to note the position of the chassis of the less powerful module.  Placing hottest modules (scanners, Ara, RF, etc.) will reduce the thermal emf.
