Working with SFP modules and fiber optic cables

Each storage controller can have up to four Fibre Channel host ports. You use a small-form-factor
pluggable (SFP) module to connect a host port to a host. 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 connects to
an optical interface connector in a Fibre Channel HBA on a host. SFP modules are laser products.
CAUTION:
This product might contain one or more of the following devices: CD-ROM drive, DVD-ROM drive,
DVD-RAM drive, or laser module, which are Class 1 laser products. Note the following information:
v Do not remove the covers. Removing the covers of the laser product could result in exposure to
hazardous laser radiation. There are no serviceable parts inside the device.
v Use of the controls or adjustments or performance of procedures other than those specified herein
might result in hazardous radiation exposure.
(C026)
CAUTION:
Data processing environments can contain equipment transmitting on system links with laser modules
that operate at greater than Class 1 power levels. For this reason, never look into the end of an optical
fiber cable or open receptacle. (C027)

Handling fiber optic cables

Attention: To avoid damage to the fiber optic cables, follow these guidelines:
v Do not route the cable along a folding cable-management arm.
