7Appendix — Working With SFP ModulesAnd Fiber Optic CablesEach storage controller can have up to four FC host ports. A small-form-factor pluggable (SFP) module isused to connect a host port to a host or switch. The SFP module is inserted into the port, and then a fiberoptic cable is inserted into the SFP module. The other end of the fiber optic cable is connected to anoptical interface connector either in a FC HBA on a host or a switch. SFP modules are laser products.WARNING: Data processing environments can contain equipment transmitting on system linkswith laser modules that operate at greater than Class 1 power levels. Never look into the end ofan optical fiber cable or open receptacle.Guidelines For Using SFP ModulesThe storage array requires SFP modules. SFP modules convert electrical signals to optical signals that arerequired for FC transmission to and from RAID controller modules. After installing the SFP modules, fiberoptic cables are used to connect the storage array to other FC devices. Before installing SFP modules andfiber optic cables, read the following information:• Use only Dell supported SFPs with the Dell PowerVault MD3860f series storage arrays. Other genericSFPs are not supported and may not work with the storage arrays.• The SFP module housing has an integral guide key that is designed to ensure you insert the SFPmodule correctly.CAUTION: Use minimal pressure when inserting an SFP module into a FC port. Forcing the SFPmodule into a port may damage the SFP module or the port.• You can install or remove the SFP module while the port is powered on.• You must install the SFP module into a port before you connect the fiber optic cable.• You must remove the fiber optic cable from the SFP module before you remove the SFP module fromthe port.CAUTION: When handling static-sensitive devices, take precautions to avoid damaging theproduct from static electricity.Installing SFP ModulesTo install SFP modules:1. If all the FC IN ports have an SFP module installed, go to step 5.2. Remove the SFP module from the static protective package.3. Remove the protective cap from the SFP module and SFP port.NOTE: Store the protective caps for future use.4. Insert the SFP module into the host port until it clicks into place.32
