Appendix—Working With SFP
Modules and Fiber Optic Cables
Each 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 or switch. The SFP module is inserted into the port, and then a fiber
optic cable is inserted into the SFP module. The other end of the fiber optic
cable is connected to an optical 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 links with laser modules that operate at greater than Class 1 power
levels. Never look into the end of an optical fiber cable or open receptacle.
Guidelines for Using SFP Modules
The storage array requires SFP modules. SFP modules convert electrical
signals to optical signals that are required for FC transmission to and from
RAID controller modules. After installing the SFP modules, fiber optic cables
are used to connect the storage array to other FC devices. Before installing
SFP modules and fiber optic cables, read the following information:
• Use only Dell supported SFPs with the Dell PowerVault MD3600f series
storage arrays. Other generic SFPs are not 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 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 or
the port.
• You can install or remove the SFP module while the port is powered on.
