Before you begin

Observe the following precautions when replacing a module.

CAUTION:

• Removing a module significantly changes air flow within the

enclosure. All enclosure bays must be populated with a module

or blanking panel 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.

NOTE:

Port-colored (purple) latches on components mean the

component is hot-swappable. It can be removed and replaced

without having to power the system down.

NOTE:

All disk enclosures will ship with two I/O modules installed and

ready for use. However, in some of the configurations, they will

only cable up and use one of them. In those environments, the

I/O module is not hot-pluggable. An I/O module is only

hot-pluggable when both are in use but one has failed or is

failing.

NOTE:

Illustrations in this document may show modules or a chassis

that differ from your device. However, replacement procedures

are the same for all chassis that use this component.
