VoIP Power-over-Ethernet – How to Connect a POE Phone to a Non-POE Switch

power-over-ethernetvoip

I'm working on a project where I need to make a network for all PCs in the site.
I need about 8 Ethernet sockets in each office of the site.
I found that there's already two Ethernet sockets in each office but they are connected to VoIP phones (Siemens openstage 15) .

So, I bought d-link switches (des 1008a) for each office and decided to expand the network inside each office by connecting one of the already existing sockets to the dlink switch and then connect the PCs and phones to the new switch.

The problem arose when I connected the VoIP phone to the dlink switch, it didn't boot up.
I discovered that the phone is powered through Power Over Ethernet and when connected to the normal non-PoE dlink switch it doesn't work even though the main cable entering to the DLink switch is coming from a POE switch. The phone works only when connected to the cable coming from the POE switch.

When I searched for the power specs of this specific phone model (Siemens Openstage 15) I found these specs ..

How can I solve this situation without expanding new cables from the main POE switch?

A little late to the party on this one, but just came across this myself today.

Plug the VoIP phone into the PoE switch like normal. Then have the port from your VoIP phone that is labeled "PC" connect to your non-PoE switch and distribute to the rest of your PCs with the rest of the open ports from your non-PoE switch.

This may be what PsychoData is saying, but it wasn't clear to me. So kudos to you if it was :)
