This document contains the steps in replacing a SAS expander module in a 4U enclosure. More detailed information is
found in the Hardware Maintenance and Installation Guide (HMIG) for the Exos Corvault 4U106, Exos E 4U106 storage
systems, and Exos AP 4U100 Integrated Storage Servers. You can find the documents located at

To remove and replace a SAS expander module:
1. If you plan on removing all SAS expander modules, properly shut down the storage enclosure.
2. Retrieve the new SAS expander module in its static-protected container, ready to access and use it upon removal of
the faulty one.
3. (Optional) As an extra safety measure while installing drive modules, support the storage enclosure with a
mechanical lift to avoid any potential issues caused by downward forces.
4. Facing the front of the rack cabinet, loosen the storage enclosure chassis flanges by twisting the top captive
thumbscrew on each side of the storage enclosure to the left.
5. Lower the pull handles then gently and steadily pull the storage enclosure out on its rails until it locks in the service
position.
6. After locating the main bay cover's front or rear latch, depending on the location of the SAS expander module you
need to replace, push on the tab, release it by pressing the latch away from the front or rear panel and toward the
hinge, then resting the open half of the cover on the closed half.
7. Locate the SAS expander module you need to replace from its location against the chassis sidewall and opposite the
auxiliary bay.
NOTE: The fault LED for each SAS expander module is on the component side of SAS expander module and has a steady
or blinking amber LED if a fault condition exists. Otherwise, it is off to indicate the SAS expander module is functioning
normally.
8. Grasping a release latch in either hand, simultaneously lift both release latches away from center until it disengages
from the SAS riser sideplane.
9. Lift straight up on the SAS expander module, carefully removing it from its slot and set it aside.
