Figure 6-6 SPA Removal
This completes the procedure for removing a SPA from the SIP.
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.
