HP J4121A Procurve 4000M Switch in basement closet
On the last module of the switch there is room for 1 cable and the module has an sticker with "A". The cable from this goes through the floors to the server room where it connects to an HP Procurve 1600M Switch in a 100/1000Base T module marked with an "A" (there is only one port on this module)
Another cable is connected to a misc. port on the 4000M switch and goes through the floors to the server room where it connects to Port 1 of HP ProCurve 10/100 Hub. (the MDI button is pushed in)
HP Procurve 1600M and 10/100 Hub are in a rack that is full...
I have purchased a new rack and an HP 12 port 2512 Switch (J4812A) for this rack. I don't have any experience with switches and need some help for how to connect this.
Thanks Experts for any help (This question is urgent).
