Component replacement guidelines

CAUTION:
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 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. For more information on interpreting
the LED displays, see
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.
