hey guys
had a question
i have a cisco catalyst 24 port 3560 switch with POE
the company is small, we have all 24 ports being used at the moment, but here is the thing, our phones are VOIP, so there are really 12 ports being used by phones, and the users computers plug into the phones,
the other 12 are devices that do not need/have phones, such as network printers, copiers, etc
is there anyway to add a switch to this switch so i can free up 7 ports for more phones? meaning, unplug all the cables that are going to the ports on the switch that is there that do not need phone connections, and plug in a switch, then plug in all the devices to that switch? let me know your thoughts, we are trying to avoid purchasing another switch.

You can get hold of another switch and uplink it to the Cisco. Just plug one of the cisco switch ports into a port on the new switch. You can then move devices that don;t need PoE onto the new switch and use the free'd up Cisco ports for more phones.

Are all of the devices being moved to the additional switch in the same VLAN? If so, then no config change it necessary. Just use one of the ports that was connected to a device and connect it to the new switch instead.

If the devices are in different VLANs then things get... interesting. You'll need to create a trunk between the two switches.

Correct.
