The compliance statement is located on the module. Before powering the library off to remove a card, review the LEDs on the back of each card to ensure there is no activity (see "Interpreting Library LEDs" on page 4-17). Removing a Card 1.

replacing cards and major assemblies.
Failure to follow proper procedures could lead to intermittent failures or
premature hard failures.
CAUTION
The Fibre Channel printed circuit boards may contain a laser system
(GBIC or GLM module) that is classified as a
“
Class-I Laser Product
”
under a U.S. Department of Health and Human Services (DHHS)
Radiation Performance standard according to the Radiation Control for
Health and Safety Act of 1968 and EN60825-1(+A11) safety of laser
products. The compliance statement is located on the module.
Before powering the library off to remove a card, review the LEDs on the
back of each card to ensure there is no activity (see
