What kind of HP switches should I I get for our new VoIP system?

[Nido1]

We are going to implement a new VOIP system soon and I'm wondering what kind of HP switches should I get? There are 80 employees in the building who will use the IP telephones and interent. Anyone please suggest PoE HP switches. Should we get procure layer 2 or layer 3 switches? Two (2) switches for ground floor and two (2) switches at first floor. Thanks!

Truly difficult to give you a reasonable answer: it all depends on Network Topology (both physical and logical) you are planning to deploy (as example: do you need a Switch Layer 3 capable which will act as Core - no need PoE+ on Core - for your infrastructure? ...or do you need that Voice dedicated VLAN has its dedicated DHCP Server managed by the Core Switch? "entry" level access switches like 2530 (no SFP+ capable) / 2540 (SFP+ capable) PoE+ are/aren't good enough? do you need to stack - virtual switching - at access level or not? do you prefer a modular switch at Core like 5400R zl2 or a 3810M will suffice? ...and so on...).

It's not only a matter of configuring and transporting a (tagged) Voice VLAN up to the access ports to then connect VoIP Terminals (note: a Voice VLAN is supported basically on every actual Aruba switch series...), it's more related on how you are planning your network topology.

Thank you Parnassus for your valuable reply. We need 4 POE switches 24 ports at access layer. These switches will connect 80 employes to VOIP and internet as well. I will share a complete toplogy and other details with you next week. Thanks again!
