Is there a Cisco fanless 12 port or 24 port POE switch, gigabit?
I installed a 3750G-24 port switch in my office and the thing is loud, starting to get annoying.

I need at least 9 ports with the uplink, hence the 12 port minimum.

We have two different telecoms setup here. Anyhow, I want to move the Xerox machine with a dedicated line to another room. the dedicated fax line is using a RJ11 and ther eis also a RJ45 data port being used. The other room is setup for RJ45.

My issue is moving the dedicated Fax line. The line comes to the printer with no moving room. I'll either leave the box in place and use a longer Ethernet cable and wire it for RJ11 and move it to the other room. I haven't climbed into the ceiling yet to see if there is extra wire but I have to move it over 50 feet. I was thinking to leave the box in place and put a cable into the box and then feed it back up to the ceiling and run it across to the other room I need to put the Xerox in.

Does anyone have an easier way of doing this or any other ideas? I hope this makes sense...

Any questions please let me know.  I can also attach pictures...

I need to have a reliable power backup for my network server (and, if possible, for my workstations as well, although not as important).  I need some type of power backup that will not only keep my system running for at least a couple hours during a power outage, but also with the capability to be able to be remotely restarted (if necessary) after the power comes back on, if the power outage exceeds the battery backup time-frame.  My situation is going to be that I will be out-of-state and connecting remotely, working with a simple laptop, but need to have access to my computer network (approx. 3,000 miles away) for my daily work as well as maintaining a remote access environment for my users!  If anyone has any suggestions for me, I would appreciate hearing them.  TIA, Jim

Spectrum/Charter installed modem at local church and it cannot connect Mac laptop to Internet. The modem replaced earlier installation which failed. Charter says new installation works OK.

Should this connection work OK?

Hello - we recently installed a new ASA5516 firewall, and have been having our US users access the ASA's public address in order to install the new AnyConnect software - which has been working.  We have a user in France, however, who is being blocked apparently due to the server not being trusted and a missing security certificate.  We do not have a security certificate for the ASA yet, so we're wondering if theres a way around this without having to install a certificate - like we do with the other US users?

hi ASA 9.1 (4)

make an audio call through ASA - weird on rare occasion i can hear audio. - then same call majority of times no audio.
the call is made from tablet inside lan  to phone on inside on LAN- it goes out ASA through to internet and back in through asa.
sip and h323 and skinny inspect ON. - Ive tried turning off makes no difference.

ports for audio open  8500-8598 UDP - how can it be a port issue if it works on occasion? unless some dynamic port happening?
is it something to do with NAT ?

thanks

Anyone has preferences and why?  Would it make sense to go with Cisco WAP Aironet, etc,   if the rest of the devices are Cisco.  Switches, routers, etc.

We are provisioned Two 2960x Cisco Switches and linked up with a FlexStack Plus cables/modules. All connected devices (e.g. Windows Servers) has two UTPs connecting to the switches, one to switch A and another one to switch B. The switches are implementing Channel Group using LACP where port from Switch A and Port from Switch B are belongs to the same Channel Group for network resilience purpose. Also, we have created TWO VLAN on the switches where each VLAN span across the two switches some network device are belong to VLAN 1 and some are VLAN 2. This is a floor level implementation and we have an uplink router (Core Switch) to route packet between VLANs.

We are planning to add more devices and we are running out of switch ports. Our expansion planning are as follows:

Option 1) Add another two network switches (i.e. 2960x) to the FlexStack cluster and create additional channel groups with switch port from Switch C and Switch D. So that the new devices can connecting to the new Switch C & D while still maintaining the resilience requirement as well as able to communication with the original devices connecting to switch A & B.

Option 2) Option 1 is only feasible if we have enough room to accommodate another two switches on the same rack. If however, we need to put the new two switches on another rack with is around 10-20 meters away still connecting themselves with FlexStack Plus, we are planning to purchase a 10G SFP+ module on the switches and link up Switches A/B …

Good afternoon Experts,

Our Security Manager asked me to upgrade his existing IP camera network from 10/100 to Gigabit from our Control Room to our guard stations, roughly 150 meters away. The existing network we have been using is 2 Comnet devices, model CNFE6+2USPOE. More details on this device here:

http://www.comnet.net/comnet-products/ethernet/self-managed-switches/cnfe62uspoe.html

I decided to purchase 2 Netgear, model ProSafe-GS110TP:

https://www.netgear.com/support/product/GS510TPP.aspx

Connected with TrendNET TEG-MGBSX SFP Modules

https://www.trendnet.com/products/proddetail?prod=200_TEG-MGBSX


My issue is that I get no link light when I set up a switches in both locations. I have tested the units side by side and it all works, but for some reason when I get them set up in their specific location I no longer get link lights. I'm using the existing fiber run that the Comnet devices are on, and have confirmed it's 50/125 fiber, and I've tested the new short fiber cables we bought and they work as well. The TrendNET SFP modules should be rated at 550 meters.

In my other experience things like this just fire up, then you make sure the VLAN's are correct, but in this case I get link down in the Netgear GUI and obviously no sweet flashing green light.

Am I missing the forest through the trees here?

Thank you for any guidance.

Dear, we found an old switch Cisco 2960 in warehouse, it still works when we plug in the power but we 'd like to make sure it will not suddenly die. So how can I check the health of that switch? Can anyone please suggest some commands to check:
- When was it used for the first time?
- How long can it be used?

We want to utilize it for a new project so please help! Many thanks!

Dear Team, is there any free tool (like Nagios, Zabbix) that can monitor the status of Hardware (orange or green lights, temporary,...) ?
Many thanks in advance.

Before designing new network for the remote offices.
What information is critical (must know) before making a decision on design, connectivity, device models, etc, etc.  Just need to be prepared before throwing a design.  Want to make is a standard base across all remote offices.  
Appreciate all the recommendations and ideas!

I need to run ONE CAT6 cable to 40 offices.

Each office is to have three Ethernet points but  only ONE Ethernet point will be in use at a time.

Three Ethernet points are there for desk orientation only.

Don;t want to have to re-patch on demand etc.. Any ideas?

Hi All,
What's a good way to practice your skills on firewalls, like ASA, palo alto or any other.
It seems like you can do labs on routers and switches and build your own topology in GNS3 or packettracer but I don't know how to get familiar with firewalls, is it just a matter of you just have to get thrown in fire to learn.
thanks for your input..

Hello - we upgraded from a 5510 ASA to a 5516 recently.  On our old 5510, the home page of the ASA would present the ASDM tool.  the 5516 does not do this.  After spending an hour reading the Getting Started guide and online, I find lots of information about how the ASDM works - but hardly any help on how to actually launch the tool.  Need some help from the experts.  thanks

Hi,
Because I live in a small space I've been struggling with wifi interfering with my bluetooth devices.

Things I CANNOT do:
  • Move the router farther away: It's already as far away as it can get (about 5 feet).
  • Use the 5GHz frequency: The wifi devices in question only work on 2.4GHz

Things I've already tried:
  • The transmission power is set to low
  • Disabled Smart Connect

What settings can I change on my D-Link AC3200 router in order to make it interfere less with bluetooth frequencies? Some options are to change the wi-fi channel from 11. Other options are to change the 802.11 mode or channel width.

I spent good money on this router years ago before I used bluetooth much. Now I use bluetooth much more. Should I sell this router and get one which behaves better with bluetooth in small spaces? Other than the bluetooth interference it's been a rock solid router even when I lived in a much larger space.

My primary bluetooth uses are headphones and video game console controllers in case it matters.

I had a printer exported over WiFi on my Windows 7 desktop system so I could print on it from other computers in the house though their WiFi connecton.   Then I changed the Windows 7 internet from Comcast to AT&T.  AT&T gave me a new router with a new WiFi network name and password, so the other computers could no longer find  the printer. I redefined the WiFi connection on the other computers to the AT&T WiFi but  I'm still not prining from the other computers.  it seems the printer on Windows 7 has been exported to the Comcast router, which is dead now.   So how do I export the printer on my Windows 7 system to the new AT&T router.  If I can do that I expect the other computers will see the printer now that their WiFi points to the AT&T WiFi.

Thanks for any help.

I own an Avaya ACS509 R7 BUSINESS PHONE SYSTEM NAMED PARTNER. One of the extensions,the main programming extension number 10 is not functioning 100%.There is an illuminated button that can be designated as DND (Do Not Disturb). The button does make a click in the receiver but does not turn on the DND feature nor does the led come on. I have tried several identical phones on that  line and none of them work. All of them work different extensions. So, I must assume it is the main controller board. I am an Electronic Technician and probably can repair it IF I could locate a complete schematic diagram along with pcb board layout pictorials and part numbers/values. I do NOT need the programming manual or user's manual. ONLY a technical repair manual. They must exist somewhere since there are several locations that will repair this motherboard. I would really appreciate it if any Expert could direct me to a pdf or similar for this unit. It is also referred to as an ACS-R7 unit. Anyone assisting me will be the recipient of 735 virtual Kudos!

NOTE: This is NOT a voip system. Just a regular 20 extension phone system.
