Working With SFP Modules and Fiber Optic Cables 31BWorking With SFP Modules andFiber Optic CablesEach storage controller can have up to four FC host ports. A small-form-factor pluggable (SFP) module is used to connect a host port to a host orswitch. The SFP module is inserted into the port, and then a fiber optic cableis inserted into the SFP module. The other end of the fiber optic cable isconnected to an optical interface connector either in a FC HBA on a host or aswitch. SFP modules are laser products.WARNING: Data processing environments can contain equipment transmittingon system links with laser modules that operate at greater than Class 1 powerlevels. Never look into the end of an optical fiber cable or open receptacle.Guidelines for Using SFP ModulesThe storage array requires SFP modules. SFP modules convert electricalsignals to optical signals that are required for FC transmission to and fromRAID controller modules. After installing the SFP modules, fiber optic cablesare used to connect the storage array to other FC devices. Before installingSFP modules and fiber optic cables, read the following information:• Use only Dell supported SFPs with the PowerVault MD3600f series storagearrays. Other generic SFPs are not supported and may not work with thestorage arrays.• The SFP module housing has an integral guide key that is designed toprevent you from inserting the SFP module incorrectly.• Use minimal pressure when inserting an SFP module into a FC port.Forcing the SFP module into a port may damage the SFP module orthe port.• You can install or remove the SFP module while the port is powered on.
