enclosure. All enclosure bays must be populated with a module
or blank for the enclosure to cool properly. If a module fails,
leave it in place in the enclosure until a new module is available to install.
• Parts can be damaged by electrostatic discharge. Use proper
anti-static protection. Refer to the documentation that shipped
with your system for additional information.
