Optical Device Installation and Maintenance

Optical Device Installation and Maintenance

This section describes the Cisco SFP and SFP+ transceiver modules installation and maintenance.

Installing and Removing Cisco SFP and SFP+ Transceiver Modules

For information on installing and removing Cisco SFP and SFP+ transceiver modules, see the
SFP+ Transceiver Module Installation Notes
For details about supported SFP and SFP+ modules, see the

Cleaning Optical Devices

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.

Cisco Wideband SIP and SPA PLD Configuration Image Upgrades

The programmable logic device (PLD) configuration images for the Cisco Wideband SIP and Cisco Wideband
SPA are automatically upgraded. Both upgrade processes require no user intervention.
• The Cisco Wideband SIP field-programmable gate array (FPGA) configuration image is not persistent.
• The Cisco Wideband SPA FPGAs and Complex Programmable Logic Devices (CPLDs) use configuration

images that are automatically upgraded as needed. The upgrade information is part of the Cisco IOS
release rather than a separate file to be downloaded by users. The Cisco IOS build contains a specific
revision of the FPGA and CPLD images. When a Cisco Wideband SPA is powered up, if the Cisco IOS
build has FPGA and CPLD images that are newer than those resident in the Cisco Wideband SPA, the
FPGAs and CPLDs are automatically upgraded. The FPGA upgrade process takes about 12 minutes per
Cisco Wideband SPA. The CPLD upgrade process takes about 13 seconds per Cisco Wideband SPA.
