Cables and connectors | You can install any transceiver supported
by the PIC. Note:
To extend the life of the laser, when a PIC is not being
actively used with any valid links, take the PIC offline until you
are ready to establish a link to another device. For information about
taking a PIC offline, see the request chassis pic offline command in the Junos OS System Basics and Services Command Reference. |
LEDs | One tricolor per port: - Off—Not enabled
- Green—Online with no alarms or failures
- Yellow—Online with alarms for remote failures
- Red—Active with a local alarm; router has detected
a failure
|
Alarms, errors, and events | - SONET alarms:
- Alarm indication signal—line (AIS-L)
- Alarm indication signal—path (AIS-P)
- Bit error rate—signal degrade (BERR-SD)
- Bit error rate—signal fail (BERR-SF)
- Bit interleaved parity (BIP) error B1, B2, B3
- Far-end bit error: remote error indication—line
(REI-L), far-end line coding violations (CV-LFE)
- Far-end bit error: remote error indication—path
(REI-P), far-end path coding violations (CV-PFE)
- Loss of frame (LOF)
- Loss of pointer (LOP-P)
- Loss of signal (LOS)
- Payload 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:
- Administrative unit alarm indication signal (AU-AIS)
- Bit error rate signal degrade (BERR-SD)
