4.2 Monitoring SwitchMaster™ Bridge Operation
SwitchMaster™ Eight Segment Bridge operation is monitored by observing
Bridge Status and Segment Status LEDs on the SwitchMaster™ Bridge front
panel.
Monitoring Bridge Status LEDs during Operation
SwitchMaster™ Bridge Status LEDs are located on the SwitchMaster™
Bridge front panel.
NOTE: When the SwitchMaster™ Eight Segment Bridge is functioning
normally, the eight Status indicators cycle in a steady roll. STATIC Bridge
Status LED displays, whether illuminated or not illuminated, indicate
critical SwitchMaster™ Bridge error for which Transition Engineering
Technical Support should be contacted.
At power on or reset, the SwitchMaster™ Eight Segment Bridge cycles
through three distinct operational phases. The operational phase, and the
transitions between operational phases, are monitored by the Bridge Status
LEDs.
Patterns observable in the Bridge Status LEDs include:
•
Power on diagnostic test patterns
(phase 0)
•
Software loading pattern
(phase 1)
•
Operation pattern
(phase 2)
Phase Transitions
The SwitchMaster™ Bridge Status LEDs flash for twenty seconds, indicating
transition from phase 0 to phase 1 and then from phase 1 to phase 2.
