Management Port
The Management port provides a connection to the 10/100/1000 network or a direct
connection to a PC's 10/100/1000 Ethernet adapter. The Management port is used for the
following:
• Configuring the Xgig1000 chassis using the Xgig Web Utility
• Controlling the operation of Xgig application-specific blades
• Retrieving data collected by Xgig application-specific blades
Console Port
The Console port is a 9-pin serial port on the back of the chassis. The Console port is used
for the following:
• Minor troubleshooting
• Basic administration
The Console port can be used for all system configuration through a command line inter-
face. Configuration commands are passed to Xgig by connecting the Console port to a
terminal or to a PC with a terminal emulation program using a cross-over cable. However,
configuration is usually performed using the Xgig Web Utility over the internet through the
10/100/1000 Ethernet management port.
Trigger/TTL Ports
The TTL Input and TTL Output ports provide a means of sending or receiving an electrical
signal between the Xgig and other instruments for triggering purposes.
The trigger-out pulse is approximately 200ns wide, active-high, LVTTL (3.3V). The trigger-
in can handle 3.3V or 5.0V inputs, also active-high. Use 50 ohm cables with these ports.
Cascade Ports
The Cascade In and Cascade Out ports provide a means of time-synchronizing up to four
Xgig, Xgig5000, and/or Xgig1000 chassis. Cascade Ports are used to share domains and
send triggers between chassis.
Cascade ports use standard RJ-45 connectors and straight through CAT5 cables to
connect chassis, but use Viavi proprietary protocol to communicate between cascaded
units.
