Solved: WS-X6348 Module use for non-POE?

frank_nye · ‎01-28-2008

We have two WS-X6348 48-port RJ-45 power-over-ethernet (POE) cards in our 6509 switch. We do not need to use these cards for POE. Can they be used for non-POE devices without any problem? Does the card have to be configured as such? We are worried about damaging equipment (non-POE device, the WS-X6348 card or the 6509 chasiss itself).

Can anyone render any advice relating to this?

Thank you!

Frank,

Yes, you can use this module for non-PoE devices. The switch uses CDP to determine if the connected device needs power or not. See the following link for confirmation.

Brandon,

Thanks for the reply. I see that it does state that the switch is smart enough to know an IP phone from a NIC card and not send power if it doesn't need it.

I had also found a section in the Cat 6500 Switch Software Configuration Guide entitled "Setting the Power Mode of a Port or Group of Ports" which shows a sample of the following command:

set port inlinepower 2/5 off

I'm not sure if I should use that just to be sure or if that command is form something else all together.

Thanks for your assistance!

Sincerely,

Frank Nye

Frank,

You could certainly use this command to turn off power capabilities to a switch port. It's not necessary in your scenario as the switch will not supply power to a device that does not need power, but it wouldn't hurt anything.

While you can use the WS-X6348 card with Non-PoE Device, I would also take a look at the power consumption of this module, so you can provision your power supply accordingly.
