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.
