System Power Switch
Use the Power switch to power the system unit on and off.
NOTICE: There is no need to manually shut down the HP-UX operating system on your workstation before powering it off. When you turn off the power switch, your workstation automatically shuts down the operating system before terminating the power.
Power LED
The Power LED lights when the system unit power is on.
System LEDs
The system LEDs indicate the status of your workstation. In the event of a system problem, the LEDs are lighted in different patterns to indicate error codes. See Chapter 6 for a complete list of the system LED error codes.

Audio Controls
Next to the system LEDs are the following audio controls:
Headset Jack |
Accommodates mini-headphones with a 3.5-mm diame- |
|
ter miniature stereo plug. |
Volume Control |
Adjusts the audio output volume to the headset jack or |
|
line out. |
Mic Jack |
Accommodates microphones with a 3.5-mm diameter |
|
miniature stereo plug. |
Mute Button |
Turns off the audio output to line out and speaker only. |
The Volume Control, Headphone Jack, and Mic (microphone) Jack features of the CD-ROM are supported through software applications only.
For more information on the features and electrical specifications, see “Audio Connectors” later in this chapter.
Removable Storage Devices
The Models B132L/B132L+/B160L/B180L support the following removable storage devices:
•CD-ROM Disc Drive
•DDS-Format Tape Drive
•Floppy Diskette Drive
Due to space limitations, a DDS-format tape drive and a CD-ROM drive cannot both be mounted in the system at the same time. Also, adding either a DDS tape or CD-ROM takes on internal drive bay, leaving only one internal drive bay available for a hard disk drive.
A description of each drive’s controls and indicators is in the chapter describing that device, later in this book.

Security Loop
The security loop provides a means of locking the storage tray, with a padlock or other locking device, to prevent unauthorized removal from the system.
Audio Connectors
Your workstation has audio input and output capability through external input and output connectors on the rear panel and through an internal speaker. The rear panel contains the Audio IN (stereo line-in) and Audio OUT (stereo line-out) connectors.
NOTICE: To maintain compliance with FCC/CISPR B you must use fully shielded, unbalanced audio cables and plugs.
The audio connectors are standard stereo audio mini-jacks. Hewlett-Packard recommends using gold-plated plugs available through audio retailers for best quality recording and playback through the external connectors. The following is a summary of the workstation audio features:
•Audio Features
Programmable sample rates:
8kHz, 16kHz, 32kHz, 48kHz, 11.025kHz, 22.05kHz, and 44.1kHz.
Programmable output attenuation: 0 to -96dB in -1.5dB steps
Programmable input gain:
0 to 22.5dB in 1.5dB steps Input monitoring:
16-bit linear, 8-bit u-law, or A-law coding
