Online Insertion and Removal Cisco ASR 1000 Series Aggregation Services Routers SIPs and SPAs support online insertion and removal (OIR). SPAs can be inserted or removed independently from the SIP. OIR of a SIP with installed SPAs is also supported. For more information about performing OIR, refer to the "Preparing for Online Removal of a SIP" section on page 5-2. Optical Device Maintenance Any contamination of the fiber connection can cause failure of the component or failure of the whole system. A particle that partially or completely blocks the core generates strong back reflections, which can cause instability in the laser system. Inspection, cleaning, and reinspection are critical steps to take before making fiber-optic connections.
