Attention notices

An attention notice indicates the possibility of damage to a program, device,
or system, or to data. An exclamation point symbol may accompany an
attention notice, but is not required. A sample attention notice follows:
Laser safety
When using an NVRAM5 or NVRAM6 cluster media converter, the storage
system must be installed in a restricted access location.
This equipment contains Class 1 laser products, and complies with FDA
radiation Performance Standards, 21 CFR Subchapter J and the international
laser safety standard IEC 825-2.
Attention: In the United States, use only SFP or GBIC optical transceivers
that comply with the FDA radiation performance standards, 21 CFR
Subchapter J. Internationally, use only SFP or GBIC optical transceivers that
comply with IEC standard 825–1. Optical products that do not comply with
these standards may produce light that is hazardous to the eyes.
Usage restrictions
The optical ports of the modules must be terminated with an optical
connector or with a dust plug.
Attention: Do not bend a fibre cable to a radius less than 5 cm (2
in.); you can damage the cable. Tie wraps are not recommended for
optical cables because they can be easily overtightened, causing
damage to the cable.
CAUTION:
This product contains a Class 1M laser. Do not view directly with
optical instruments. (C028)
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)
