Hi - currently we have several Cisco 2960-24PC-S 10/100 POE switches, that we are going to be replacing with Cisco Catalyst 2960X-24PD-L POE switches, because of age and the need for the gigabit connection. My question is (my limited Cisco knowledge) that we have SFP Modules that we cant seem to figure out the model #. In the inventory on the switch it shows up next to the Description as "1000BaseSX SFP", and the serial number below it. Does anyone know if these are compatible with the 2960X switches?

Hello,
I have few offices that I need to support, I always assist remotely the business users.
Was wondering if there is a KVM switch that connects to the internet, and then I can plug it to a computer via USB and VGA so I can control the machine remotely, even via the bios. Kinda like HO iLO.

Any recommendations ?

Hello Experts,

I am trying to design WLAN solution in open facility, due to cabling\connectivity issue following proposal is provided:

Assume a lager circular facility and outdoor APs (around 120 aps) need to be installed at peripheral.

 we don't have POE option and to install multiple switches thus I need to validate following solution will work?

1.  run fiber across the periphery.
2. connect fiber end to Switch and trunk it with vlan 10, define dhcp scope for vlan 10
3. splice fiber across the periphery at AP connectivity point.
4. use fiber to Ethernet converters.
5. we can use external power injectors.

would appreciate your help in validation.

TIA

Dear experts,

I have wireless keypad for my laptop -windows 10.

I use it both for my  normal text typing as well as for c language.

Is there a separate set-up required for keypad when using it for typing languages syntax (for instance || and \)

The reason is I do see the key strokes on the keypad but when I type it types different characters.

Kindly guide me to switch between these two requirements.

Thank you

Hi,
I would like to setup a home network on 4 desktops.
1) Dell Precision T7500 Workstation 10 years old
2) Dell Inspiron Quad core desktop 10 years old
3) Lenovo ?? small desktop 6-7 years old
4) Custon built new desktop high spec i9 CPU etc
Currently I am connected to Virgin broadband and router
has 4 ports, only 2 available for computers.
What type of hub do I need to accomplish this.?
It's not essential that all four computers be connected to the internet
Two would be sufficient. I have no intention of sending data out over the internet.
The main function would be to share files between all four computers.
Any help/advice most appreciated.
Thanks
Ian

I have a Seagate Central NAS drive at home and it has been working fine until just recently.

I can no longer connect to the NAS contents through Windows Explorer; I see it listed on network items but am unable to view the contents. I am able to connect to the Seagate Manager which shows me the IP address connection, users etc etc; I can change its name and it is reflected in Windows Explorer which shows that it is connected to the network.

I have read that it is something to do with Server Message Block v1 (SMB v1) settings which have been updated in Windows 10. I have tried updating the firmware on the NAS but it says it is already running latest firmware.

Any suggestions for overcoming this?? NAS holds all of our files; documents, music, photos etc.

Need a pocket Bluetooth transmitter.

I have a Sony $20 clip-on microphone I really like, but instead of plugging it into my pocket MP3 recorder, I want the sound to go right to my PC and become part of my video.

Is this what I need?

https://www.amazon.com/Bluetooth-Transmitter-Receiver-Adapter-Headphones/dp/B01M9B2YSV/ref=sr_1_8?ie=UTF8&qid=1527646460&sr=8-8&keywords=bluetooth+wireless+transmitter

Something tells me this thing needs power.

I need a battery powered BT transmitter that take a normal jack from a microphone.

What do you suggest I use??

Thanks

Hi all,

TIA.

I plan on having a small public facing web site to allow for licensing of a client app sitting on the server I use for internal use.

I understand the best way to do this is through the DMZ. I have not done this before and I want to ensure I do this properly, is the attached diagram correct or should I be going in a completely different way?

Thanks

We have purchased a Netgear Nighthawk X10 ad700 model R900 router and we are unable to use it.
The issue is when we configure the router, they are getting connected but then they are automatically getting reset within an hour. we are not able to configure again for the day.
Can someone help us to sort out this issue?

As you can see from the pic below, there is inconsistency in the aggregated links. Sw2 has 3 members in po10 and sw1 only has 2. How will the traffic for vlan1 flows from sw2 to sw1? Will it take ten1/9/3 into its decision to send the frames to sw1? How about sw1 STP, will it block e2/9? Thanks

I am looking for a Program or Script to dial remote Hayes AT Modems and log results. We have a large number of Hayes compatible modems connected to Verizon POTS lines. Many of these modems are in locations where there are frequent service interruptions. We would like to automate testing the availability and logging results. Is anyone aware of how we can do this?

We have a Technicolor Modem/wireless router combo device given by Spectrum.  When Spectrum tech first set it up I could connect to is wirelessly and I could see the public wan IP as ie. 1.2.3.4.  We plugged it into our Sonicwall device and everything is working fine.  Bridge mode is enabled and we have a dynamic public ip so I set it to DHCP.   I just want to know why  I'm getting a address of 192.168.0.5 showing on my WAN.  I was expecting to see the public ip instead like 1.2.3.4.

Good Day,

I am thinking of sharing internet between two different offices. Kindly advise the best device to use, because we got fiber into the first office and don't want to pay multiple internet fees for the other office.


Based on google maps the distance is roughly: 250Meters, these buildings are the tallest around.

I need a 95% always working system , as internet is very key to e-commerce operation.

Do I run another fiber or simply use a bridge?

Hi Experts

Could you point how to check if an internet modem/ instalation is using Optical Fiber in oposition to a coaxial cable?

I means in hardware characteristics and speeds.

Thanks in advance

We have an APC AP9631 network card for a UPS that I think is defective. When I assign it an IP address through the front panel of the UPS, the settings don't save. I replaced the card with another one and it works.

APC wanted me to try doing a remote connect through a serial cable but that didn't seem to work. Now we have had to send the UPS to site and I can't get to it anymore.

APC says they haven't confirmed the card is defective so can't replace it. Has anyone seen the behaviour above and were still able to fix it?

From a best practice standpoint which is better, ASA on the edge or a router on the edge of your network?


off of the top of my head ASA on the seem like a better design, however, I have seen some networks in the passed with Router(Edge) then ASA.

Hi, we have a switch that is outdoors, and it gets to be about 110-120 degrees here in the summer. I need something that can handle that type of heat - a 8-12 port gig is OK.

Please let me know what works.
