•
Unknown Port
Indicates that the floating Jammer license dongle has been removed, and the Jammers have
been terminated. In this case, the port icons turn white to indicate that the ports have changed
to an unknown state. From this state, the ports can be configured to operate as any other
licensed function.
Port Selection and Other Indicators
•
Selected
(port icon background is Blue)
Indicates the port is selected as part of the domain. You can select a port that is locked or has
triggered and assign it to a domain. However, you may not be able to lock the port or start a
capture if the port is locked by another user.
•
Unselected and Unlocked
(port icon background is White)
Indicates the port is not selected as part of the domain and is not locked by another user.
•
Locked
(lock appears in the port icon)
Another user or another instance of TraceControl owns the port-pair. The port-pair is
unavailable for capture.
• Port Triggered
Indicates that data received on this port has triggered the ports of the domain.
• Port Locked and Triggered
Indicates that data received on this port has triggered the ports in another user’s domain. The
port is locked by another user.
•
License Missing
Indicates that the license key for this port is invalid or missing. The port is not usable until a
proper license key is entered. The licensing for different functions is entered using the Xgig
Web Utility. See
“Licensing for Xgig Multi-Function Blades” on page 44 for more
information.
Xgig Port Selection by Chassis or Blade
Ports are displayed within blades, and blades are displayed within chassis. Port-pairs are the unit
that is added to the domain selection. As a shortcut for all Xgig chassis, you can select a chassis
and add all its ports to the domain by clicking on the logo above the chassis name. You can also
click the blade area surrounding ports to add all the ports in the blade to the domain.
Select TTL In or TTL Out
Each chassis in the Port display has a TTL IN and a TTL OUT port, representing the TTL In and
TTL Out ports on the chassis. A physical connection to pass trigger information between two
systems must be established using a BNC cable for Xgig or an MCX cable for Xgig5000 and
Xgig1000 to use this feature. To use the chassis as the sending device, you must connect the TTL
Output port of the chassis sending the external trigger to the receiving device. To use the chassis as
the receiving device, you must connect the TTL Input port of the chassis receiving the external
pulse to the external sending device.
Caution: Improper connection of BNC or MCX input and output cables can cause serious
damage to the system. Please double-check to make sure that the TTL Input port and/or TTL
Output port of a chassis are properly connected to other Viavi devices or blades.
