connecting 2 switches

[trauts14]

i have an 8 port poe switch. 4 ports are poe. i need more poe ports so if i buy another switch and connect the 2 will i run into problems or signal lose? i figured by buying another small switch it would be cheaper than buying a 12 or 16 port poe switch.

for what it is worth the poe is for my network camera.

No problem Today's switches can be "daisy-chained" by connecting one port on each together. Older switches had a dedicated "uplink" port for this.

Just be cautious that the devices plugged into the PoE ports follow the rules and are PoE compatible or if they don't use PoE, that they do not use the extra wires for PoE.

I'm not sure how this relates to PoE with gigabit though.

Note that most but not all consumer network cameras send power over ethernet but it is NOT the IEEE 802.3af standard which is up to 48V. If you have a simple consumer camera that runs on 5V or 12V, you don't use a PoE switch- instead use a little box called a power inserter. I would't call a camera running on 5V/12V "PoE" as PoE means 802.3af.

PoE switches supporting 802.3af are $$$$.

If the switches are basic un-managed switches, then just connect an ethernet cable on port 8 of each and that will give you 14 useable ports, of which 8 would be PoE (if you get the same switch model again).

Plug your cameras into the PoE ports on either switch and you will be just fine.
