Precautions
● Remove and insert an optical module with even force. Excessive force may
damage the appearance or connectors of the optical module.
● Do not frequently or quickly remove or insert an optical module; otherwise, it
may be damaged.
● There are four links connecting to an optical module. If you want to replace
the 8 Gbit/s Fibre Channel interface module (eight ports)/16 Gbit/s Fibre
Channel interface module (eight ports), ensure that all working links have
backup links. You are advised to disable the ports of the switch that connect
to the 8 Gbit/s Fibre Channel interface module (eight ports)/16 Gbit/s Fibre
Channel interface module (eight ports) and switch the services on these ports
to backup links to avoid interruption during the replacement.
