How to connect two switches without causing conflicts

Hi All,

I have just installed about 15 Mobotix IP Cameras on a 24 Port POE Switch in a school. The system consists of the 15 cameras, 2 Synology NAS boxs and i used my laptop plugged into the switch to program everything.

The school already has a small existing network in place to access the internet etc, I now need to connect my switch to theirs somehow so that they can view the cameras, playback etc. I do not have access to configuration of their switch, router etc other than physical access.

How will i connect the two switches together without causing conflicts to either network. My network uses all static IP Addresses, I am not sure about theirs, Could i put a second router or such between the switches???? Any ideas????

Any help would be greatly appreciated,

Thanks,

Stephen

If the cameras IP addresses are not in the same subnet as the other equipment in the network, you have to put a router, yes. But you have to configure one interface of the router with an IP from their network. If you have such an IP, it is ok.

If they are both on the same vlan (subnet) you can just plug your switch into theirs.
The dhcp they (most likely) have running will detecht the cameras ip as being in use and just give out ip's around that range.

Yes there is no problem logging on to one of their computers to find out what subnet they are using or get an IP address to use, If i put in a second router how will the switch know to route internet traffic through the original router and Camera traffic through the new router,

Will the DHCP server definitely pick up i am already usind a handful of IP addresses and keep away from these, Do i just use a crossover cable to connect the two switches???

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

the dhcp will know what is in use.
and a crossover will do the trick.

Is there a better way to connect both switches other than crossover, I want the data to be transferred as quick as i can, It becomes very noticeable if there is a delay especially in playback.

I have joined two switches like this before and it has ended up slow retrieving data, What do you think??

the quickest way is crossover
putting a router in between will only add an extra hops and cause a small delay.

Is there any special uplink port or anything i should use on the switches or is there any odds, I assume use gigabit if its available???

Thanks

unless you have managed switches that will shut of the port if they detect more than 1 device behind it, any port will do.
and if they are both gigabit switches, that will be the quickest way.
