Table 6.2 CMM and SMM/SMM-1 Connectors and Status Indicators
Connector/LED Description
Craft Terminal Interface RS-232 port, DB-9 connector. Connects to laptop computer with
Craft Management Software installed. Note that connection to a
CMM-1 is not allowed when the CMM-1 is daisy-chained to an
SMM-2.
DC/Communication
Connector
Multi-pin connector. Connects to chassis backplane. Carries DC
power and communication signals into and out of the module.
Status LED Indicates the overall status of chassis, all other installed modules,
backplane voltages, and internal temperature. Any minor or major
alarms within any power supply or application module is also
indicated.
■ Solid Green = All monitored functions within defined limits.
■ Solid Yellow = One or more functions operating beyond minor
alarm threshold but has not exceeded the major threshold.
■ Solid Red = One or more internal functions operating beyond a
major alarm threshold.
■ Off = Not defined.
■ Blinking (any color) = LED blinks during initialization and when a
user monitors the chassis using CMM with the Craft
Management Software.
PS 1 & PS 2 LEDs Indicates the status of the power supply installed in slot PS 1 or PS 2
slot, respectively.
■ Solid Green = All internal functions operating within set limits.
■ Solid Yellow = One or more internal functions operating beyond
a minor alarm threshold but has not exceeded the major
threshold.
■ Solid Red = Power supply is not installed. Power supply not
connected to AC or DC power. One or more internal functions
operating beyond a major alarm threshold.
■ Off = No module installed.
■ Blinking (any color) = LED blinks during initialization and when a
user monitors PS1 or PS2 with the Craft Management Software.
Fans LED Indicates whether fan currents are within set limits.
■ Solid Green = No alarms. All fan currents within defined limits.
■ Solid Yellow = One fan has been removed or is operating
beyond either a major or minor alarm limit. Two or more fans
are operating beyond a minor alarm limit.
■ Solid Red = Two or more fans have been removed or are
operating beyond a major alarms threshold.
■ Blinking (any color) = LED blinks during initialization process and
when a user is monitoring a fan with Craft Management Software.
