Juniper Networks Juniper M-series M10i - Manual (Page 70)

One tricolor per port:
■ Off—Not enabled
■ Green—Online with no alarms or failures
■ Amber—Online with alarms for remote failures
■ Red—Active with a local alarm; router has detected a failure
LEDs
■ SONET alarms:
■ Alarm indication signal—line (AIS-L)
■ Alarm indication signal—path (AIS-P)

■ Bit error rate signal fail (BERR-SF)
■ Bit interleaved parity (BIP) error B1
■ Bit interleaved parity (BIP) error B2
■ Bit interleaved parity (BIP) error B3
■ Loss of frame (LOF)
■ Loss of pointer (LOP-P)
■ Loss of signal (LOS)
■ Far-end bit error: remote error indication—line (REI-L) (CV-LFE)
■ Far-end bit error: remote error indication—path (REI-P) (CV-PFE)
■ Payload mismatch (path label mismatch) (PLM-P)
■ Payload unequipped (unequipped STS at path level) (UNEQ-P)
■ Remote defect indication—line (RDI-L)
■ Remote defect indication—path (RDI-P)
■ SDH alarms:
