Replacing A Drive Carrier Module - Seagate Exos E 4U106 Hardware Installation And Maintenance Manual

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 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 HS Expander 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.

Replacing a drive carrier module

A DISC drive module consists of a DISC in a carrier. DISC Drive in Carrier (DDIC) modules are hot-swappable,
which means they can be replaced without halting I/O to the DISC groups, or powering off the enclosure. The new
DISC 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 DISC to reconstruct the DISC group. Remove the top main bay cover A to
access DDICs. See
when the procedure is completed. If accessing DDICs in DISC slots 96–105, remove top controller bay cover B,
and reattach it when the procedure is completed. See also
CAUTION: Removing a DISC 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 DISCs to stop spinning, then insert the new
DISC drive module.
See CAUTION bullets regarding electrostatic discharge and anti-static protection on
TIP: The illustrations show DISC module replacement within the drive slots as you view the enclosure top panel.
