1 Product Overview

Configuration Overview

The minimum configuration consists of a 3U base module, designated Module 1, containing: the front control panel, one robotic hand, a mailslot with four slots, a power supply, and one tape drive (with options to add a second drive tray, a second power supply, or both). It stores up to 30 tapes in two, removable 15-slot magazines (one on the left side and the other on the right side). You can designate up to three reserved slots in the base module left magazine to be used for storing cleaning or diagnostic tapes.

Up to nine 2U expansion modules (designated Module 2 through Module 10) can be added to provide additional tape slot capacity (see Figure 1-1). The expansion module is connected to the base module by an expansion cable that has USB Type A connectors (see Figure 1-2). The expansion module controller receives power over the expansion cable.

Expansion modules ship without tape drive trays or power supplies. When the first tape drive tray is installed in an expansion module, a power supply must also be installed to provide power for the tape drive. A second power supply can be added for redundancy. One power supply provides adequate power for two tape drive trays.

Library System Indicators

A set of library status indicators are located on the front control panel above the left magazine (see Figure 1-3) and on the robot CRU at the back of the base module.

• Locate LED and push button switch: helps to identify the specific SL150 library in the data center. The LED is present in two places on the base module: on the front above the left magazine, and on the rear in black rectangle on the robot module. The LED is activated by pushing the locate button on the base module or by clicking the locate icon in the remote management interface.

• Fault: a fault anywhere in the library triggers the yellow fault LED.

• OK: indicates the library is functional (green), but the library might be in a degraded state (the Fault indicator is on concurrently with OK).

Human Interfaces

Graphical user interfaces provide limited local access and full role-based remote access control of the library.

• The front control panel provides a 177.8 mm (7 inch) LCD touch panel with an 800 X 480 pixel resolution. The panel is used to initialize the library with three basic settings: default password, date/time, and Port 1 network settings (see Chapter 4, "Library Initialization"). The values for the basic settings are entered from a keyboard screen (see "Installation Wizard Keyboard Screens"). When initialization is complete and the library restarts, the panel serves as an information point rather than a maintenance tool (see Figure 1-4). The masthead on the screen lists the library health state and a description of the current library state. The Home screen contains sections for the library, modules, magazines, mailslot, partitions, drives, tapes, and settings. The partitions section is not shown unless the library has been configured with partitions using the remote management interface (GUI).

• The primary management interface for the SL150 library is accessed by entering the library hostname or IP address into a web browser (for example: IE8, Firefox, Chrome, or Safari). The interface provides information for the library, drives, tapes, settings, and service depending on the user role. The interface recognizes four user roles: viewer, operator, service, and administrator.

  Figure 1-5 is an example of the screen seen by the administrator role. The Library information is presented as a graphical representation of the tape slots in the left magazine, tape slots in the right magazine, and tape drives between the magazines for each module. The mailslot is above the right magazine and the robot is above the left magazine of Module 1. Information for drives, tapes, settings, and service is generally shown in tabular format. Some screens have tabs to categorize the type of information available.

• Customer Replaceable Unit (CRU) indicators. Most CRUs have an OK indicator that shows it is operational (green). If any of those CRUs have a failure, a Fault indicator (yellow) is shown instead. The drive CRU has a blue indicator that is activated from the remote interface to indicate the CRU is safe to remove and aids in locating the specific drive needing replacement.

Installation Wizard Keyboard Screens

In general, you enter installation wizard values from a keyboard screen and tap buttons to apply selections or navigate forward and backward through the various screens.

The keyboard opens in a window with white borders. The keyboard consists of two sections (see Figure 1-6):

• Upper section: a parameter field followed by buttons

• Key section: four rows of keys (three screens to list the full keyboard content)

  • Figure 1-6 shows the letter keys

  • Figure 1-7 shows the number keys (accessed by tapping the ?123 key from either the letters screen or special characters screen)

  • Figure 1-8 shows the special characters keys (accessed by tapping the *+= key from the numbers screen)

The left key in the bottom (first) row is always a shortcut to another keyboard screen. On the numbers screen and special characters screen, the left key in the row immediately about the bottom row (second row) is a shortcut to a second keyboard screen.

Certain keys in the bottom row are standard in all keyboard screens (period, Space, @, and Enter keys).
