4. While grasping the swing-arm handle, pull upwards to lift the HS Expander and remove it from its slot.

Installing a HS Expander module

Refer to Figure 67 on page 74 and Figure 68 on page 75 when performing this procedure, but ignore the
directional arrow—since you will insert the module into the slot—rather than remove it.
Important: Handle the HS Expander module carefully to avoid damage to the connector and swing arms.
1. Check for damage, especially to all module connectors.
2. Align the controller HS Expander module for use in the module slot that is accessible from the top
panel along the right wall of the enclosure.
3. Insert the controller module into the slot, and gently press down on the module until it seats firmly in
its connector.
4. Verify that the HS Expander Status LED is off. Verify that the front panel LED states show no amber
module faults.
5. If replacing multiple HS Expanders, repeat steps 1 through 4.
6. Reattach top lid "A" when you complete the procedure.

Replacing a drive carrier module

A disk drive module consists of a disk in a carrier or sled.
Disk Drive in Carrier (DDIC) modules are hot-swappable, which means they can be replaced without
halting I/O to the declustered array or powering off the enclosure. The new disk must be of the same
type, and possess capacity equal to or greater than the one being replaced. Otherwise, the storage
system cannot use the new disk to reconstruct the disk group. Remove the top lid "A" to access DDICs.
See Figure 9 on page 12 for enclosure lid locations and labeling. Reattach top lid "A" when the procedure
is completed. If accessing DDICs in disk slots 96–105, remove top lid "B", and reattach it when the
procedure is completed. See also Figure 11 on page 13 for disk slot indexing..
CAUTION: Removing a disk drive module impacts the airflow and cooling ability of the enclosure.
If the internal temperature exceeds acceptable limits, the enclosure may overheat and
automatically shut down or restart. To avoid potential overheating, wait 20 seconds to allow the
internal disks to stop spinning, then insert the new disk drive module.
See CAUTION bullets regarding electrostatic discharge and anti-static protection.
