Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Can I load an image onto a Cisco 3850 switch which has no IOS by attaching an external DVD player to the USB port and use the command prompt to acces the burned image on the DVD pkayer disc?

I want to buy: a 4bay qnap server, but wish to confirm, How can I configure the device as a SCSi storage attached to a Windows Server.

Will this process work for it: https://www.qnap.com/tr-tr/how-to/tutorial/article/how-to-create-and-use-the-iscsi-target-service-on-a-qnap-turbo-nas   ?

I have a communication box(please refer to the attached image)  attached to the side wall of the house, IMG_1757.jpg, it contains the phone lines, internet service cable inside, , there is no way to put a lock on it, only a few screws to hold the cover, but I would like to secure it, anyone have an idea how to secure it? drill holes to hang a paddle lock? add security steel bar?  this box is very critical to me because it's connect to the alarm system.

I rewired my house with CAT6, and have a problem terminating the jacks at the end.

I bought IDEAL CAT6 jacks, which i've never really used before.  

I spent several hours on the CAT6 jacks, and I found it to be very uncomfortable.  the inner core is a nuisance -- i know it's for the better(less attenuation?)
the wires fit into the jack very loosely and i could barely guide the 8 wires in order into the terminating jack.  Once I crimped it, it was fairly loose as well -- i could pull and without exerting so much effort pull the wire back out.

i wired it once, tested it -- it failed -- no signal whatsoever.
i didn't know what was wrong and re-wired it a seocnd time, and still uncomfortable -- and failed again.

i searched for documentation and the internet is innuntdated with info on the old system using CAT5/CAT5e, and many videos even claim to show how to terminate CAT6, but don't get into the sled and liner.

i tried once more with the sled and liner using a poor IDEAL schematic, and then gave up.

after a while, of frustration i thought why not just try the CAT5e jacks -- and in 5 minutes I did what took me 4 hours previously.  felt comfortable --slid in snug, crimped strong. and tested perfectly.

my question:

can anyone provide a detailed CAT6 patch termination document including whether or not the sled and liner are necessary, and any other specifactions ( i think the wires didn't even fit in the liner)

my second question:

is performance going…

I just purchased a used Dell PS4000E SAN and have logged into the device and reset the grpadmin password.

I'm currently connected to the Dell PS4000E SAN with a serial to USB console cable (using HyperTerminal for Windows 10) and logged on with the grpadmin account.

Please provide me with step-by-step instructions on how I can reset this device back to its factory default settings and set it up for use within a Server 2016 and VMware environment.

In the groups of apartment that I stay, there's  a free Wifi for the community
which I could access from my phone/laptop when I move around the vicinity.
However, a reading room right in the centre of this area, the Wifi signal is
often cut off (or intermittently at 1 bar).

Is there anything I can get/install so that I could get the signal in the reading
room (which is a 5m x 3.5m room with glazed glass panels in front, a thick
wooden door & concrete walls on the roof & other sides of walls)?  Even if
I open the wooden door, the Wifi signal strength did not improve.

Until I shift my chair & laptop & sit just 1m outside the wooden door, then
I get 3-4 bar signal.

I don't mind a USB dongle with a 4m USB extender cable (which could be
slipped under the door but do recommend specific eBay/Amazon links
to the items that could be shipped to Singapore.

Btw, I don't have access to the AP and I can't get the management/admin
of this community to boost the signal so this is not an option.

Trying to determine the best MTU value w/Sonicwall TZ300 (latest firmware) on a cable connection.

I understand the ping command, then narrow it down till there is zero packet loss then add 28.
The ping test I'm using for example is:  ping www.yahoo.com -f -l 1492

My question is this...

What should the initial MTU settings be on the Sonicwall WAN port when performing the ping test?  Obviously it would cause the ping test to fluctuate.
Thanks in advance.

I have a (hopefully very simple question) regarding routing in a hyper-converged environment. In the simplest form, let's say we have a single HC node (HyperFlex, SimpliVity, etc.), and the VMs being hosted on this node are within a typical Web/App/DB hierarchy - so, all in different VLANs/subnets, virtual firewalls in-between, etc.

Given the above, would communication between the different tiers (W/A/DB) require exiting the HC node to an external routing device, or would the virtualization hypervisor somehow be able to handle this? (Let's assume NSX is off the table.)  This would seem to be a "normal" deployment for any HC environment, in that the more condensed the environment, the higher demand for internetwork connectivity.

I'm trying to get to whether a Layer 3 physical switch is "normal" for these environments to handle this inter-tier traffic, or if there are more efficient options.

Thank you

What is the process to reset the password for the grpadmin account password on a Dell PS4000E SAN when the password for the grpadmin account isn't known?

We have already tried the default password of grpadmin and this hasn't worked.

Is there any process for resetting the grpadmin account password back to the default password of grpadmin or setting it to something else when we don't have any of the logon account passwords for this device?

Are there any utilities or methods I can use to determine the IP address of a Dell EqualLogic PS4000E Storage Area Network (SAN) device when it's IP address and subnet mask info are unknown?

This SAN device was pulled from a working network and I am looking for a way of logging into it but first need to determine its IP address.

Are there any Dell, EqualLogic, or third-party utilities that will help me do this?

I am purchasing a used Dell EqualLogic PS4000 SAN.

We don't know the password for logging onto this unit.

We don't need to save any data on this unit.

Can someone explain me on high level Cisco licensing differences?  I understand there are lanbase, ipbase, and ip services.
For some reason Cisco sold me core switches 3850 with lanbase, but access switches with ip base licensing.  Not a production impact but Cisco TAC  raised a concern.
I need to buy more access switches.  What licenses should I get for those?  And is there a pricing difference?

Thanks in advance.

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
