Table 4 describes the BIP LEDs and indicators.

Table 4 BIP LEDs and indicators

Item	Label/Icon	Type	Color/State	Description
1	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).
2		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).
3		LED	Green/On steady	Shelf alarm cable validation LED —The shelf alarm
				cables are properly connected to the shelves.
