Installing SFP modules

The FAStT100 host ports require SFP modules. SFP modules are used to convert
electrical signals to optical signals that are required for fibre channel transmission to
and from RAID controllers. The FAStT100 supports two types of SFP modules: one
with a plastic latch and one with a wire latch. After you install the SFP modules, you
use fiber-optic cables to connect the FAStT100 to other fibre channel devices.
Before you install SFP modules and fiber-optic cables, read the following
information:
v Do not mix long-wave SFPs and short-wave SFPs on a single storage server.
v The SFP module housing has an integral guide key designed to prevent you from
v Use minimal pressure when you insert the SFP module into a port. Forcing the
v You can insert or remove the SFP module while the port is powered on.
v The operational loop performance is not affected when you install or remove an
v You must insert the SFP module into a port before you connect the fiber-optic
