The physical interfaces include the dual power plugs for the redundant power supplies, the power and reset buttons, the serial port, the LAN Port RJ-45 connector, and up to six slots containing additional network connectors. The power and reset buttons light up to indicate power and hard disk activity respectively. Each RJ-45 connector is accompanied with Light Emitting Diodes (LEDs), including green and orange LEDs on the LAN Port, and Link/Activity and 10/100Mbps LEDs on the 10/100BASE-TX LAN ports.
