PowerVault MD1xxx Family Serviceability Capabilities
• All the major PowerVault MD1xxx Family components are easily accessible and
replaceable even when in a rack.
• PowerVault MD1xxx Family storage enclosures are equipped with LED indicators for
visual status reporting on the status of internal components.
• A PowerVault MD1xxx Family storage enclosure’s audible alarm notifies users of
critical/non-critical status. (For details, see PowerVault MD1xxx Family Hardware Owners
Manual). Status is also reported to the host system’s management tool, Server
Administrator. (For details, see the OpenManage User’s Guide.)
• PowerVault MD1xxx Family storage enclosures use the Dell Update Utility (DUP) for
downloading firmware during serviceability. In a daisy-chain configuration, all EMMs in the
configuration are updated via a single DUP instance on the host. After a firmware
download, all updated enclosures and the host server must be power cycled for the
changes to take effect.
