Questions about this item

How loud or hot does the Firebox M390 get when running continuously?

The appliance has eight Gigabit RJ-45 ports and one expansion slot; no fan noise or thermal data is published by the manufacturer.

What cables or modules do I need to connect the eight 10/100/1000Base-T ports?

Standard Cat5e or Cat6 Ethernet cables with RJ-45 plugs are required for each of the eight ports.

Will the Firebox M390 work alongside my existing 10/100 switches and older routers?

Yes, each port auto-negotiates down to 10 or 100 Mbps so legacy 10/100 gear connects without configuration changes.
