Precautions Specific to WWN Cards
Observe the following precautions for these cards:
•
Wear an appropriately grounded ESD wrist strap when handling and installing device blades and cards. Follow
electrostatic discharge (ESD) precautions. Wear a wrist grounding strap connected to chassis ground (if the chassis is
plugged in) or a bench ground.
•
The device will operate with one WWN card, but will be in degraded condition. If you have removed a card, be sure to
replace as soon as possible.
NOTE
Do not use steps in the WWN card and WWN card bezel removal procedures to disable logical switches and
power down the device.
DANGER
For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.
CAUTION

devices in their static-protective packages until you are ready to install them.
