It is possible that the ports are busted already.

We have a Linksys SRW2048 48-Port Gigabit Ethernet Switch. The problem is, that we can't get a connection on the 8 ports on the very right side. What could be the problem, how can we solve it?


Disconnect all the Ethernet cables from all the ports.
Connect one of those eight "bad" ports to your laptop.
See if the port works when it is the ONLY active port.
If not, move the cable to the next of the eight "bad" ports, and test again. Repeat.
Move the cable to one of the 40 "good" ports, and test.
If it works, then you have a hardware problem with that "group" of 8 ports.

Your choice to use only the 40 "good" ports, or to replace the router, if you need those last 8 ports.

Netgear FSM7352S - VLAN not connecting


Create the same VLAN on all the switches that will need this VLAN. All ports that link to another switch should have ALL VLAN's set to tagged.
This one VLAN should not have an IP address on any of your switches. This way it won't get routed by any of your users.

Fsm750s 48 port - we had ports 9,10,11,12 go out in a storm - can they be repaired? power on/off didn't reset - going into the Netgear via IP and disabling and enabling also did not work


Unfortunately, nothing to be done other than replace it if you need the ports. You could in theory replace the chip or chips that got burned up but it would probably not be worth it and it it's an ASIC(likely) you'll probably not even be able to source it.

Trying to connect 4 dsl routers to 48 port switch


Are you trying to set up router ?
You can set up your router manually, without the CD.
Make sure that your computer is able to go online directly through the modem.
If your computer is able to go online through the modem, that means the modem is working fine.
You will need to connect the computer to the router and the modem to the router.
open the set up page of the router and change the settings of the router according to the ISP.

The purpose of hp procure switch 2626


There is nothing special about these switches other than that they are managed. Managed means they have some means of connecting to them and "managing" them like you do when you configure a wireless router by going to some ip address in your browser to access the configuration. They usually are able to communicate statistics, set up virtual subnetworks, monitor ports, mirror ports, control which ports can access which others, set speed limits on ports, etc... A normal switch is "dumb", there is nothing to configure and it just does it's thing, connecting anybody and everybody that are connected to any of it's ports. Procurve switches are popular because they are great switches, there are other managed ones that can be had for much less, I use 48 port managed Linksys that have/exceed these capabilities for way cheaper... examples
