Command Line Interface

The command line interface (CLI) is used exclusively by Oracle support to configure
and diagnose the library. Service representatives can access the CLI through the
electronic control module using either of the following:
Serial Port Connection on the HBCR card (RS-232) and a HyperTerminal
■
connection to enter the commands
Ethernet Port Connection (ports 1A, 2A, or 2B) on the HBCR card and a secure
■
shell (PuTTY) to enter the commands

Redundant Electronics

The optional redundant electronics (RE) feature is available for failover protection for
the HBCR controller card. With the RE feature, each library has two HBCR controller
cards. If the active library controller experiences errors, operations switch
automatically to the stand-by library controller, with minimal disruption to library and
host operations.
RE is not available for libraries that use the direct FC-SCSI connection to hosts (refer to
the SL3000 Host Connectivity Guide and the SL3000 User's Guide).

Robotics

The robot in the SL3000 library is called a TallBot. Each library can have either one
(standard) or two TallBots (redundant robotics option). TallBots retrieve and insert
cartridges into CAPs or slots and mount or dismount cartridges from tape drives.
TallBots move along two rails on the rear wall of the library. One rail is at the top of the
library and one rail attaches to the floor. Two copper strips in the top rail provide
power and a signal path between the TallBot and library controller (HBCR) card.
Power is supplied from +48 VDC 1200 W load sharing supplies (see
and Cooling").
TallBots contain a bar-code scanner that reads the configuration blocks in each module
during library initialization and identifies volume serial numbers (VOLSERs) of
cartridges during CAP entries and audits.

Redundant Robotics

The optional redundant robotics feature increases the speed for robotic operations and
allows library operations to continue if one robot fails. Redundant robotics requires
240 VAC, 2N power, and two PEMs or two AEMs.

Cartridge Access Ports - Rotational

The cartridge access port (CAP) is a vertically-mounted, rotating cylinder with two
removable 13-slot magazines.
The Base module comes standard with a CAP.

card (8 Gb) for Fibre Channel interface connections. This card is not
shown in the figure but is installed below the HBCR card.
