Replacing an HS Expander module
Procedures for the removal and installation of HS expander modules.
This section provides procedures for replacing a failed HS Expander module. Illustrations in HS Expander
replacement procedures show top panel views of the enclosure, with the module properly oriented for
insertion into the top panel of the enclosure near the right wall.
If a HS Expander module fails, the remaining modules are sufficient to maintain operation of the
enclosure. You need not halt operations and completely power-off the enclosure when replacing only one
HS Expander module.
See CAUTION bullets regarding electrostatic discharge and anti-static protection in the “ESD
precautions” on page 55 section.
Tip: The illustrations show controller fan module replacement as you face the enclosure front and view
the top panel. See also Figure 11 on page 12 and Figure 9 on page 11
Removing an HS Expander module
About this task
CAUTION: Removing this hot-swappable PCBA disrupts the enclosure’s airflow. Do not remove
the PCBA until you have received the replacement. It is important that all CRU module slots are
filled when the enclosure is in operation.
Procedure
1. Remove the top lid “A” to access the HS Expander module. See Figure 9 on page 11
2. On the faulty HS Expander, grasp each of the two plastic swing-arms between thumb and index finger
as shown in the figure below.
