Storing and handling components
It is recommended to use these guidelines if you do not install replacement
components immediately:
l
Storage location temperature must remain constant ranging from -40° to 158°F
(from -40°C to 70°C).
l
Store on a dry surface or floor, away from direct sunlight, heat, and air
conditioning ducts.
l
Store in a dust-free environment.
CAUTION
ESD damage can occur when components are mishandled. Always wear an ESD-
preventive wrist or heel ground strap when handling the S4048–ON and its
accessories. After you remove the original packaging, place the S4048–ON and
its components on an anti-static surface.
Replacing a fan module
The S3048-ON supports two airflow direction options. Do not mix airflow types in a
chassis; you can use only a single airflow direction in a chassis. If the airflow directions
are mismatched, the S4048-ON powers down in one minute.
To run the system, the three fan module slots must have operating fan modules. If you
do not install a module in each slot, the system shuts down in one minute.
CAUTION
ESD damage can occur if components are mishandled. Always wear an ESD-
preventive wrist or heel ground strap when handling the S4048–ON and its
components.
Procedure
1. Remove the replacement fan module from the electro-static bag and place it on
an anti-static surface.
