CAUTION This library contains very sensitive electronic 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 contain a laser system 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.
Removing a Card
1. Review the LEDs on the back of each card to ensure there is no
activity on the card (see “Using Library LEDs to Diagnose Status” on
page 5-4).
2. Note the library front panel configuration settings (if you will be
replacing the controller card), and power off the library. These
settings include:
• Password
• Network Access
• Mailslot
• Fibre Channel or SCSI IDs
3. Power off the library. Do not remove cards while the library is powered
on.
4. Note how the library is cabled and the position of the card.
5. Remove all external cables attached to the card.
