Devices
When planning to use the router, consider the number of devices and the
anticipated demand. This determines the number of ports required and in turn the
number of routers.
The router uses SFP transceivers in the 8-Gbps Fibre Channel (FC) ports, but
some FC devices may not use the same transceivers. Consider whether the FC
device you want to connect the router to uses SFP or gigabit interface converters
(GBIC) transceivers, and choose fibre optic cables accordingly. Use LC-type
cable connectors for SFP transceivers and SC-type cable connectors for GBIC
transceivers. Also consider the transmission speed compatibility of your devices,
host bus adapters (HBAs), switches, and SFPs.
