4. While grasping the swing-arm handle, pull upwards to lift the HS Expander and remove it from its slot.
Installing an HS Expander module
About this task
Refer to Figure 33 on page 62 and Figure 34 on page 63 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.
Procedure
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 Step 1 through Step 4
6. Reattach top lid “A” when you complete the procedure.
Replacing a drive carrier module
Procedures for the removal and installation of 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 disk groups, 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 11 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 12 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.
