Extending Cisco Phone Switch

Hi,

I have a couple of 24-port Cisco phone switches (3560G, PoE series) ... all of the ports are used, and I need to add another couple of phones to the network.

Is this as easy as obtaining any PoE switch (as I do not have any power adapters for the Cisco phones) and extending it that way, or do I need a special kind of switch, or special configuration?

If I can't simply extend by hooking up a switch, what do I need to do?

Thanks.

Adding another POE switch will do. It will make things easier for you if you're adding the same kind you're already using.

So, you would recommend adding another 3560G? Adding another 9-port PoE Cisco switch might work, but might complicate things? I'm not up on configuring/managing Cisco voice stuff, so whatever I would need to plug it in and have it work, is what I'm probably after.

(Sorry ... not 9-port, but 8-port :))

Go with what you have already.

sr ... could you elaborate? The only thing I already currently have is 48 used ports (no free ports and no extra PoE switches).

PowerEdge Tech,

If you got a second 3560G, you could then use the CAB-SFP-50CM= SFP interconnect cable to connect the two together rather than creating an port channel between the two.

dvon ... if I understand what you're saying, currently one of the existing 48 ports might be being utilized to connect the two switches ... if that is the case, I could free up two of those ports by using the special cable you mention? I will definitely look at that when I get to work on Monday as a short-term fix, but I think I would prefer a solution that allows me the single port I need now, but also allows me the ability to add additional phones later.

Thanks.

I see. jm said it would be "easier" to use another of the same switch. Since I'm after a solution that is as simple as possible to implement, would you recommend the same, or will any PoE switch work to simply plug it in and have it work?

DvonHoltz

P.E.T., correct, you want to use another 3560 to take advantage of the CAB-SFP cable

Thank you all for the input. Thanks eeRoot for explaining "why" the same (or similar) model would be better.
