I need some advice as I am not very knowledgable on HP Procurve switches. I currently have a main HP Procurve 4202-48G (J8771A) with a Procurve mini-GBIC module (J877A) connected to a HP Procurve 2810-24G (J9021A) with a GBIC module. These are about a 100,000sq/ft apart so fiber was used. They are connected and stacked using a fiber connection. A Homaco rack unit is installed at both ends for the fiber. Please see the attached pictures. We just inherited 2 HP Procurve 4000M 80 + 48 Port 10/100 Switch J4121A.
Switch 1 - 80 Ports (10x J4111A) Single Power Supply
Switch 2 - 48 Ports (6x J4111A) Dual Power Supply
Will these be compatible with my current setup? Could I replace my Procurve 2810 with this? I like all the additional ports compared to my current 2810-24g
