DD580, DD565, DD530, and DD510 Systems 51Hardware OverviewHardware InterfaceConsole port Monitor(VGA) porteth0eth1Figure 18: Hardware interface panelKeyboardportThe hardware interface panel is where you connect to a Data Domain system with a serial console,a monitor and keyboard, or through an Ethernet connection. See Figure 18 on page 51. TheEthernet interfaces eth0 and eth1 are for data transfer to the Data Domain system or foradministrative access over a network. Both Ethernet interfaces are 1000 Base-T Gigabit copperports that can accept 10/100 Base-T or Gigabit connections. The four USB ports below the Ethernetports are currently not used.Each Ethernet connection has two LEDs, one on each side. The left LED is the Link/Activity LED.When the LED on the left side is dark, the port has no live connection. The LED glows green whena link is established and flashes green with transmit/receive traffic. The speed LED (on the rightside of the connector) indicates 1000-Mbps operation when amber, 100-Mbps when green and10-Mbps when off.
