right. The module controller holds the MODULE INPUT port for the module
interconnect cable and the status LEDs for the module.
Customer Replaceable Units are secured to the rear of base and expansion modules
using easily removable fasteners. The robot/library controller, tape drives, and power
supplies are attached by green, captive thumbscrews that can be loosened with a
common Phillips screw driver and tightened by hand. The expansion module
controller is secured by a latch and lever that can be operated without tools.
Browser-based User Interface
The SL150 library user interface is your main tool for configuring, monitoring, and
troubleshooting the library. It combines comprehensive library management,
monitoring, and security features with ease of access and deployment. The user
interface is a web application, so there is nothing to install or administer on user
workstations. Once you have set up the library's network interface, users enter the
library's host name or IP address into a standards-compliant web browser, such as
Mozilla Firefox, open the application in a browser window, log in, and work.
The dashboard is the key part of the interface and appears at the top of every panel. At
left, it hosts a remote power button (a vertical bar enclosed by a circle), a remote
library-locator button (concentric circles interrupted by a triangle), and, when the
library is busy, a Busy... indicator. The dashboard displays the Library Health at center
(Operational, Degraded, or Failed) and the connection state of the library (typically
Online or Offline) at right. If you click on a Degraded value in the Library Health
field, the user interface displays a tabular list of failed and degraded components. The
currently logged in user is displayed at far right. When you are ready to end your
session, click the Log Out control to its immediate left. This secures the interface and
logs you off of the system. The Preferences control lets you Pause Automatic Refresh
of the display and Resume Automatic Refresh when ready.
