The RMU resides in each system and is pre-installed at the factory. The RMU
allows remote access via a Web browser to the library. All available functions,
as described below, are completed without the need of a dedicated server (or
separate software).
The RMU performs the following functions:
Provides remote operation of all library Operator Panel functions via a
Web browser.
Allows you to check the status of the system, firmware levels, and other
useful information.
Updates RMU, drive, and Library Controller firmware.
Supports Simple Network Management Protocol (SNMP) and acts as an SNMP-server,
generating SNMP traps and responding to SNMP requests.
Supports Library Management Information Base (MIB) version 2.0.
Detects a power loss and generates an SNMP trap for notification.
Enables the retrieval of library, drive, and RMU diagnostic files.
Allows RMU configuration changes such as network, users, and date/time
changes.
