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 SFP+s with the Dell PowerVault MD3600f series storage arrays. Other generic 
SFP+s 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.
• 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 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.
WARNING: When handling static-sensitive devices, take precautions to avoid damaging the 
product from static electricity.
Removing SFP+ Modules
To remove SFP+ modules:
1.
Remove the FC cable from the SFP+ module.
See 
2. Unlock the SFP+ module latch. For SFP+ modules that contain wire tabs, unlock the SFP+ module 
latch by pulling the wire latch outward 90°.
