Laser Safety Information
The optical drive in this system unit is a classified as a Class 1 level Laser product. The
optical drive has a label that identifies its classification.
The optical drive in this system unit is certified in the U.S. to conform to the requirements of
the Department of Health and Human Services 21 Code of Federal Regulations (DHHS 21
CFR) Subchapter J for Class 1 laser products. Elsewhere, the drive is certified to conform to
the requirements of the International Electrotechnical Commission (IEC) 60825–1: 2001 and
CENELEC EN 60825–1: 1994 for Class 1 laser products.
CAUTION:
Invisible laser radiation when open. Do not stare into beam or view directly with
optical instruments.
Class 1 Laser products are not considered to be hazardous. The optical drive contains
internally a Class 3B gallium–arsenide laser that is nominally 30 milliwatts at 830
nanometers. The design incorporates a combination of enclosures, electronics, and
redundant interlocks such that there is no exposure to laser radiation above a Class 1 level
during normal operation, user maintenance, or servicing conditions.
Data Integrity and Verification
Warning:
Bull NovaScale Servers are designed to reduce the risk of undetected data corruption
or loss. However, if unplanned outages or system failures occur, users are strongly
advised to check the accuracy of the operations performed and the data saved or
transmitted by the system at the time of outage or failure.
