SFP modules
Statement 3:
CAUTION:
When laser products (such as CD-ROMs, DVD drives, fiber-optic devices, or
transmitters) are installed, note the following:
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 controls or adjustments or performance of procedures other than
those specified herein might result in hazardous radiation exposure.
DANGER
Some laser products contain an embedded Class 3A or Class 3B laser
diode. Note the following.
Laser radiation when open. Do not stare into the beam, do not view directly
with optical instruments, and avoid direct exposure to the beam.

The storage subsystem supports a fiber-optic interface for host and storage
expansion enclosure connections. You must install a Small Form-factor Pluggable
(SFP) module in each interface connector on the controller where a fiber-optic cable
is to be installed. Do not install an SFP in any port that will not have a fiber-optic
cable attached. Remove any SFP from any port that does not have fiber-optic
cables attached.
The DS5020 storage subsystem host ports support 2, 4, and 8 Gbps Fibre Channel
speeds. The DS5020 storage subsystem drive ports support only 4 Gbps Fibre
Channel speeds.
