Should not be any problem stacking the PoE and Non- PoE 62xx switches. There is a stacking kit you can purchase: Each PowerConnect 62xx series switch stacking module kit will includes: •One stacking module card •One three meter stacking module cable [IMAGE] console>enable console#show switch    Management Standby   Preconfig     Plugged-in     Switch        Code SW  Status     Status     Model ID       Model ID     Status        Version --- ---------- --------- ------------- ------------- ------------- ----------- 1   Mgmt Sw               PCT6224       PCT6224       OK             2.2.0.3 2   Stack Mbr  Oper Stby PCT6224P      PCT6224P       OK           2.2.0.3 3   Stack Mbr             PCT6224       PCT6224         OK 2.2.0.3 console#
I just want to be sure that there are no issues stacking the 6224P with the non-PoE 6248.   I'd also appreciate knowing what module(s) I'd need to add to my order to connect these two switches. Thanks.
