Removing and Replacing Cards
CAUTION This library contains very sensitive electrical components. It is important
to follow the proper procedures to prevent electrostatic discharge (ESD).
Use wrist-grounding straps and anti-static mats when removing and
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.
Removing a Card
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).
1. Note the library configuration settings (if you will be downloading
new firmware), and power off the library.
2. Note how the library is connected and the placement of the card, and
then remove all external cables attached to the card.
3. Loosen the two thumbscrews on the card by hand or with a
screwdriver.
4. Remove the card by gently pulling it outward.
