Performance Monitoring
This chapter defines the M1-3 front panel LED indications and the
Performance/Status Menu report registers. M1-3 performance can
be monitored with the aid of:
• Front Panel LEDs
• Performance/Status Menus
The M1-3 provides a statistics buffer that stores event data. The
event data thresholds are configured in the Performance/Status
Threshold Setting submenu.
When a threshold setting is exceeded, the M1-3 stores that data in
the statistics buffer. If the M1-3 encounters an error, it notifies the
SCM of an alarm condition. Both the SCM and the M1-3 display an
alarm indication (LEDs).
NOTE: The alarm LED color is dependent on the type of alarm.
M1-3 LED Indicators
The M1-3 front-panel LED indicators change color to indicate when
errors are found at the T3 or T1 line (red or amber) or system
equipment problems (red). Errors are recorded in the status report
of the Performance/Status Menu. The are three M1-3 LEDs:
• T3 port
• T1 port
• System
Power On Self
Test
The M1-3 front-panel LED indicators flash red and green in rapid
succession during self test. The firmware implements a power-on
self-test (POST) each time the M1-3 is powered. The POST
implementation validates the functionality of each major hardware
subsystem in less than 10 seconds.
