2.7.1 LED and Button Descriptions
This section describes the LEDs, buttons, and connectors on the module and UPAS.
LEDs on the Far Left Side of the UPAS
• Green PWR (Power) indicator LED for UPAS: Lights when unit power is
switched on.
• Red Status indicator LED for UPAS: Lights during boot up.
LEDs and Button on the UPAS under the Left Module Slot
The LEDs and button on the UPAS enclosure under the left module slot function in
conjunction with the USBTracer module inserted above it:
• Green REC (Recording) LED: Lights when the unit is recording.
• Orange TRG (Triggered) LED: Lights when the unit triggers on an event.
• Green UPLD (Upload): Lights when unit is uploading data to PC.
• Manual Trigger push-button: Allows a manual Trace capture.
LEDs and Button on the UPAS under the Right Module Slot
The LEDs and button under the right module slot are reserved for LeCroy generator
modules such as the USBTrainer USB Traffic Generator (described in Traffic Generation
(2.0) on page 277):
• Green HS: Illuminates when Hi-Speed is being generated.
• Orange Classic: Illuminates when Full or Low Speed is being generated.
Classic also illuminates during power-on testing and is turned off at the end of
the power-on cycle. If the LED blinks at the end of this cycle, the hardware is
faulty.
• Green Intelliframe: Illuminates when Intelliframe traffic is being generated
using Intelliframe mode, an intelligent adaptive traffic mode. If off, the
generation is in Bitstream mode. See “Traffic Generation Modes: Bitstream
vs. Intelliframe” on page 291 for more information.
• Start/Stop: Push-button allows manual Trace capture.
