Sun Fire 280R cable connections
The following figure shows where cables connect to the back of the back of the Sun Fire
280R platform.
Label Function and Troubleshooting Considerations
1 PCI card slots - Cables connect NMS cards to the MultiVantage (DEFINITY) system
or to digital telephony lines. Problems here may interfere with receiving and
handling calls.
2 Serial connector a - The cable connects the video monitor to the IR system.
Problems here may cause the video monitor to appear blank, even though the IR
system is still processing calls.
3 Serial connector b - Cable connects the IR system to the external modem, which
controls dial-up access to the system for Avaya support technicians. Problems here
might mean that Avaya support technicians are unable to access the IR system for
troubleshooting.
4 Parallel connector
5 UltraSCSI connector
6, 7 USB connectors (four) - Two of these connectors are reserved for the keyboard and
mouse that are part of the country kit. If a keyboard is not connected, and the IR
system is rebooted, you may not be able to log into the IR system. Your
organization may use the remaining USB connectors for other purposes.
