7Appendix — Working 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 toconnect a host port to a host or switch. The SFP module is inserted into the port, and then a fiber optic cable is insertedinto the SFP module. The other end of the fiber optic cable is connected to an optical interface connector either in a FCHBA on a host or a switch. SFP modules are laser products.WARNING: Data processing environments can contain equipment transmitting on system links with laser modulesthat operate at greater than Class 1 power levels. Never look into the end of an optical fiber cable or openreceptacle.Guidelines For Using SFP ModulesThe storage array requires SFP modules. SFP modules convert electrical signals to optical signals that are required forFC transmission to and from RAID controller modules. After installing the SFP modules, fiber optic cables are used toconnect the storage array to other FC devices. Before installing SFP modules and fiber optic cables, read the followinginformation:• Use only Dell supported SFPs with the Dell PowerVault MD3660f series storage arrays. Other generic SFPs arenot supported and may not work with the storage arrays.• The SFP module housing has an integral guide key that is designed to prevent you from inserting the SFP moduleincorrectly.• Use minimal pressure when inserting an SFP module into a FC port. Forcing the SFP module into a port maydamage 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 from the port.CAUTION: When handling static-sensitive devices, take precautions to avoid damaging the product from staticelectricity.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.5. Connect an FC cable.See Installing Fibre Channel Cables.21
