• HP ZBook F0U66EA and integrated Thunderbolt port question

  Hello!

  The Thunderbolt on HP ZBook F0U66EA port will work with the new Thunderbolt optical cable to 30 m? Or for only 2 meters copper cables?

  Tnks!

  The zBook works with any cable Thunderbolt, copper or fiber.  Copper to Fiber Converter is in the cable itself, not the PC, and the cables can operate with any port Thunderbolt.

  Fiber optic cables have a much greater range than copper cables, but they won't deliver power to the terminal, the terminal must be powered from wall.

• IP address on the cell phone?

  I have a question and couldn't find a definitive answer, so I'm here. As the line object suggests, cell phones have an IP that are associated with them, if I'm NOT using a wifi connection?

  For example, if I visited a forum I am a member and do not connect, is not the forum would know it of me? Would they see as something associated with Verizon? How does it work?

  System/network/security engineer by trade, I do not know what as a fingerprint.

  If you visit a web site, the web server sees your IP address. If you come on the WiFi from home your IP address usually maps near your location - at least on the State level. If your IP address is working and your work is giant Corporation, your IP address may map to a head office in another State.

  If you use 3G (or 4 mythical g) then you hit a cell tower, which is connected by fiber or copper back to your cellular provider office is close and then usually connected by fiber to one of their main offices where you arrive finally on the internet. It's our main office, that the IP address of your phone is usually associated - if you are on AT & T, which is repeatedly Dallas, Texas.

  Many web sites may report that your IP address and where they think you are are:

  http://whatismyipaddress.com/ is a site, but there are many others. Keep in mind that any physical location data connection can get embusked quickly and companies pay other companies to constantly updated lists of what the IP is there - way phone numbers get reused and assigned to different people on different streets.

  In regards to Web sites remember who you are if you do not have to connect - this is done with cookies and MrNoSox said. Some sites also use Flash Shared Objects, which are Flash cookies. cookies operate on all browsers and no matter what type of connection. Your IP address is recorded as well, but sites assume that it passes between the visits and allowing cookies on your computer - so regardless of the connection mode, they see the cookie and know it is come back you.

  Some customer companies of using cookies and IP address block - this is why Canadian users cannot watch HULU.com - the ip address corresponds to the Canada and they can get a deposited cookie on their machine too - but most often they are only blocked by its IP address - whole countries can be blocked.

• Port of UTP on WLC4402

  I searched ORC almost all, but I can't find the answer: do I need a GBIC int the 4402, or can I use the utility of 1 Gbps port?

  I understand the service port is just for the management, but I can't find if I need a GBIC. I have a UTP network only...

  Thanks for any response,

  Marcel

  You must use the SFP (smaller than the GBIC, but does the same thing) with modules SFP fiber or copper port. 2 SFP ports on the 4402 are indispensable to connect wireless to wired infrastructure. The switch ports to which you connect the SFP ports to be in trunking mode and can be in the etherchannel mode too if you use the offset on the controllers feature. If you do not use the function of offset on the controller, it is recommended that two ports connected to the same switch because of the way the network processing unit (npu) on the functions of controller to tie together the two ports.

• Question about Nexus and catalyst

  Hello

  I have a few questions on Nexus switches and how they compare with the catalyst.

  With the 2248TP Nexus can be managed without needing a switch like the Nexus 5 k parent?

  It would not be a good review of select Nexus as a catalyst?

  That snap Nexus would be a good catalyst replacement 3850?  It's in terms of cost and bandwidth capacity.

  When you buy SPF + transievers of these switches, they come in pairs for two switches or just a transiever?

  Kind regards

  Waqas

  Hello

  With the 2248TP Nexus can be managed without needing a switch like the Nexus 5 k parent?

  No, 2 k switches need a switch to parent, it might be a 5 k, 6 k, or a k 7.

  It would not be a good review of select Nexus as a catalyst?

  It depends on your need.  The 3850 is mainly a copper switch with fiber uplink.  5Ks are mainly a switch of fiber with copper modules, that you can buy.  The Nexus series does not support POE, but make the 3800 series.  So, everything depends on your applications.

  That snap Nexus would be a good catalyst replacement 3850? It's in terms of cost and bandwidth capacity.

  NEXUS series is designed for data center with a lower latency, the faster chips, the flow rate, etc... If you are designing a data center, you want the Nexus series.  Usually, the Nexus is more expensive than the 3800, but this isn't always the case.

  When you buy SPF + transievers of these switches, they come in pairs for two switches or just a transiever?

  When you buy the 2ks, they come with 8 FETs, which can be used to connect a 2ks to 5, 6 or 7ks through 4 uplinks.  FETs are Cisco propriatry optical and may not be used between the 2ks, and parent switches.

  If you need any other optical, you will have to order them separately.

• I need a Switch

  I am currently a student working on a project that got designig a network for a small business. So I was hoping that someone could suggest what turned off, I have to use the range of Cisco products. I'm going to need about 285 ports spread across 5 floors. So I think I'm going to need a combination of 24- and 48-Port switches. the network is 100 Mbps. Some of these ports are going to be for Voip, going to need a VLAN. I'm new on this isn't so sure what information you need exactly. I also need a gateway router that can handle both VoIP. Any help would be greatly appreciated.

  Thank you

  gebewick

  Let's see if I can be useful. Can you answer a few questions first on this network that you design?

  (1) what kind of applications will run on the network other than the voice?

  (2) what type of permit VOIP PBX will deploy you? (The manufacturer makes a difference because many of them use proprietary protocols)

  (3) usually 258 ports require several deployments of enterprise-level, do you know how many connections to the LAN and voice by floor connections?

  (4) what type of uplinks will be necessary between switches? Fiber or copper? 1 G or 10G maybe?

  That should be enough to start. Let me know if you have any questions.

• 10GB Ethernet - Fibre Channel

  Most of my clients can hold 10 000 to 15 000 ther budget for:

  Storage

  Infustructure network

  HBAs for ESXi host

  Are there tool or a way to find solutions for businesses who want to enter the field with Essentials more, but because of the e/s, we need more storage gigabit NIC.

  Is the next logical leap of 1 gigabit 10Gbe? Or is it Fiber Channel?

  Hey...

  "fibre channel" is essentially a storage architecture...

  You are considering fiber ethernet by opposition to the copper perhaps?... 1000BASE-SX or LX for example...

  That there is no increase in bandwidth over copper gigabit... It is used to connect longer distances, copper CAN... or connect two buildings where a connection copper between two buildings with two blocks of independent electricity is against the regulations (it is the case in the United Kingdom),

  The next viable step upwards of copper gigabit "done, team/shared resources" several gigabit copper... or 10GBE which maybe more fiber or copper.

  We use dual 10GBE fiber in our ESX host and our Center database to the production and satellite floor data centers.

  Hope that helps... after if is not the info you wanted... :-)

• Copper Fiber media converter

  Hello

  Cisco does not 10GBASE-T transceiver in his wallet for the UCS fabric interconnects, is it possible to connect the fabric of interconnections to 10GBASE-T infrastructure? I think any sort of a media converter or not...

  Thank you

  There is no "converter", you need a new switch to do, as 5596 T link.

  You are welcome.

• copper MXI noise immunity

  Ladies and gentlemen,

  Advice me please on the copper MXI link noise immunity.

  that is, crashes to the top or other problems with it

  Hi Current 93,

  The MXI - 4 and MXI-Express conform to the standards of the immunity measure, control of process and Laboratory Equipment - 61326.  This information, as well as to other EMC nonconformities found in the section titled 'Electromagnetic compatibility' in the MXI-4 kit and MXI-Express user manuals.  Second, the two protocols have error correction to ensure that the data are received successfully, even in a noisy and hard environment.  If you are concerned about the loss of data on a copper line, have you considered using a fiber optic cable?

  Comparing MXI to Ethernet, the two cables have error checking and are quite tolerant in noisy environments.  Problems with data loss on your MXI lines?

  Thank you!

• can I use both optical and fiber sfp modules?

  Hello

  I have 2 stacked 3548 P PowerConnect switches. The top switch got uplink fiber of 1 MM (G1) to another switch in a different building. If the top switch has 1 free uplink port and the lower 2 switch free uplink ports. Recently, we bought 2 servers Poweredge R620 and I would like to connect them to the Gigabit ports. The 'normal' switch ports allow only 100 Mbit/s, so I plan to buy 2 modules SFP 1000Base-T (for copper) to connect to them.

  Is this feasible? Can I use G2 on the top switch for SFP 1000Base-1 T? Is this allowed?

  Kind regards

  Erik

  Yes, it's quite feasible. The connection will be configurable the same 100 Mbps ports. Here is a link to the part number for the 1000Base-T transceiver.

• Reference Dell 6248P - Port fiber

  Hello

  I am trying to connect to port 1/xg1 (fiber Slot) on my Dell 6248P switch SFP 1 G and it's not working.

  Is that the port takes in charge only 10G?

  Thank you.

  Hello

  1/xg1 ports are 10G only. The front ports support SFP 1 G. The front ports are ports combo for 45-48 in order to use copper or fiber port, but not both.

• Question of the 6248P fiber port legacy.

  Hello

  I inherited two switches 6248P outgoing Manager (I arrived after his departure) and would like to know if the switch can add a port for a 10GBASE-SR fiber connection.  One of the switches is in place and in the course of execution attached to a 3COM older who manages currently one end of the fiber and the second unit was still in the box but has a Module SFP + 10GE (2-port) plugged into the back of it.

  Is - this module fiber or cable? Is it possible to get the fiber for this device? And what role do we need?

  Any help is appreciated.

  Page 11 of this document shows different switches 62xx expansion modules.

  i.dell.com/.../Expansion-Modules-for-Dell-PowerConnect-Switches-January2012.pdf

  Page 59 of the user guide also talks expansion modules.

  FTP.Dell.com/.../PowerConnect-6248p_User%27s%20Guide_en-US.pdf

  It looks like the module you have.

  accessories.dell.com/.../PopupProductDetail.aspx

  It provides 2 SFP + ports capable of supporting optical transceivers 10 G-BaseSR, BaseLR - 10 G and 10 G - BaseLRM. In addition, it also supports Active and Passive Direct Attach Copper cables SCXI.

  I hope this information helps.

• 3548 stacking ports... Fiber?

  I noticed, under system, advanced settings, General settings, there is an entry of stackable port with the ability to select the copper Ports or fiber.

  35xx switches can now use fiber for stacking ports?

  Someone at - it tested?

  An excerpt from the user for the 3500 model switch Guide.

  

  The front includes number of ports RJ-45 24 1-24. The top row of ports is marked with odd numbers 1-23, and the bottom row of ports is marked with the numbers 2 to 24. In addition, the façade also contains ports G3 - G4, which are copper ports and ports G1 - G2 which are fibers. G3 - G4 ports can be used as ports for stacking or used to transfer a standalone network traffic.

  I can spend some time looking into this.  At the moment it does not look like that is possible. I will update the post with all possible information that I can find.

• Tests of the fiber of a switch cables

  Hello world

  I have two new Cisco switches connected to each other through a fiber cable.

  Does anyone know of CLI commands to test the fiber of any one of the two switches cable?

  (I know that there is the command "test cable diagnostics... etc".)  But this only works with copper)

  Thank you

  There is nothing to test the fiber directly, other than an instrument of separate fiber as a light meter or an OTDR Tester

  What happens usually is to compare levels of TX and RX optics on both sides, to ensure that the signal is understood, so its scope, you should be OK. Optical levels are usually found in the transceiver interface see the display interface controllers or view the details of the interface, you may need to search to find it, don't be confused by the TX and RX thresholds

  For example, if on the first optical levels facing show is 1/TX and RX is - 5, face to face a 1 TX and RX - 22 the face is RX'ing much more wrong signal as the first side. 6 dBm is loss overall in one direction and the other way is 23, which would indicate a connection problem. Notes; a - 40 or - 50 or - 80 means no signal

• uplinks - fiber to Ethernet converters

  Hello

  I plan to use the fiber to Ethernet converters for all rising 25 and will connect to WS-C3750X-48PF-S.

  I got WS-C3750X-24 s - E in mind but need of copper as well as connections to connect routers and some other systems.

  Is it a good idea to use these converters for all uplinks or should I consider WS-C4506-E?

  You can look at the X 4500 also. They work very well as a distribution switch. Personally, I would stay away from media converters. It's one thing to fail and the majority of them have little visibility when something is not bad. However, if you decide to go with them I would look at Transition Networks.
