Half-height drives
The half-height automation panel has very similar features to the full-height version. The exterior
dimensions of the panel are smaller than those of the equivalent panels for drives designed for installing
on servers and panels for standalone drives, in order to allow the whole drive to be fitted into the
half-height form factor with no overlap.

The bezel is 4.1 mm thick.
Automation interface
The HP LTO-5 tape drive supports connection to an automation device via the serial ADI port or via
an Ethernet port. The ADI port supports the HP proprietary ACI protocol for connection to legacy
libraries and the sADT protocol. The Ethernet port supports the Internet ADT (iADT) and iADT Discovery
(iADT_DISC) protocols defined in the ADT-2 draft standard.
NOTE:
The sADT protocol is covered by two standards:
• For ADT-2, see the T10 ADT-2 Standard and the relevant ANSI standard when it is released.
• For ADC-3, see the T10 ADC-3 Standard and the relevant ANSI standard when it is released.
As the Ethernet port can be connected to devices outside the library, the drive provides support for
security in the form of optional authenticated connections. Authentication makes use of X.509 certificates
which are installed in the drive via SCSI commands defined in the proprietary Security Configuration
Protocol.
The serial automation controller connection supports a HP proprietary Automation Controller Interface
(ACI) protocol and the Automation/Drive Interface (ADI) transport protocol (ADT). Because of the
differences in these two protocols it is not possible to interleave ACI and ADI frames/commands. It
is therefore necessary for the serial automation controller connection to operate in either ACI or ADI
Mode. The tape drive defaults to ACI Mode after a power-on or hard reset if the
Sensea/ACI_LIN_SEN_L input is activated on the ADI/ACI connector. Otherwise the drive defaults
to ADI Mode. See “Automation interface” on page 70.
Connections between the library and the drive may use either or both of the physical connections:
• sADT only
• iADT only
• iADT and sADT
