ws-x4148-rj45v with linksys spa942

Unanswered Question
Feb 21st, 2007

I've got some WS-X4148-RJ45V blades in a Catalyst 4506, and some Linksys SPA942 voip phones. Is there any way to get these phones to power from the 4148 blade? Perhaps force power on a port-by-port basis? Or will I need to replace them with 4248s?



I have this problem too.

Hi Anthony,

There is not need to supply external power supply.

Is phone cannot get power from switch port,

You can configure and test following way,

Switch# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)# interface fastethernet 5/8

Switch(config-if)# power inline auto

Switch(config-if)# end

This example shows how to verify the inline power configuration for the Fast Ethernet interface 5/8.

Switch# show power inline fastethernet 5/8

Interface Admin Oper Power ( mWatt ) Device
