Upper Shelf/

LED

Red/On steady

Circuit breaker LEDs (for upper shelf and lower

 

Lower Shelf

 

 

shelf power supplies)—Indicates that a circuit

 

 

 

 

breaker has tripped due to an overcurrent condition

 

 

 

 

with the associated power supply.

 

 

 

 

This fault condition also lights the (red) MAJOR fault

 

 

 

 

indicator (see MAJOR fault description in this table).

 

 

 

 

No alarm is generated when a shelf circuit breaker

 

 

 

 

is manually switched on () or off (O).

LED

Red/On steady

Shelf alarm cable fault LED—The shelf alarm

 

 

 

 

cables are missing, not secured, or the shelf alarm

 

 

 

 

jumpers are not configured properly (see

 

 

 

 

“Accessing the alarm module” on page 30). This

 

 

 

 

fault condition also lights the MINOR fault indicator

 

 

 

 

(see Minor fault description in this table).

Green/On steady

Shelf alarm cable validation LED —The shelf alarm

 

 

 

 

cables are properly connected to the shelves.
