Component replacement guidelines
CAUTION:
Removing a component significantly changes the air flow within the enclosure. Components must be
installed for the enclosure to cool properly. If a component fails, leave it in place in the enclosure until a
new component is available to install.
Use the following guidelines when replacing a component in the HPE StoreOnce System or the HPE
StoreOnce 5100 System Capacity Upgrade enclosure.
• Before replacing a component, verify its status to ensure that it needs replacement. To verify component
status, check the status LEDs, event logs, product-specific logs, and management utilities for component
health and location information.
• Parts can be damaged by electrostatic discharge. Keep parts in electrostatic containers until needed and
ensure you are properly grounded when touching static-sensitive components.
• HPE recommends waiting until periods of low storage system activity to replace a component.
• When replacing components at the rear of the rack, cabling might obstruct access to the component.
Carefully move any cables out of the way to avoid loosening any connections. In particular, avoid cable
damage that might be caused by:
◦ Kinking or bending.
◦ Disconnecting cables without capping. If uncapped, cable performance might be impaired by contact
with dust, metal, or other surfaces.
◦ Placing removed cables on the floor or other surfaces, where they might be walked on or otherwise
compressed.
