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 Working With SFP+ Modules and Fiber Optic Cables

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°.
