Cisco 12000 series router 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.
Optical Device Installation and Removal
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.
