system LCD

The Liquid Crystal Display (LCD) is located on the left side of the front panel. The LCD displays 2-lines of information, with up to 16-characters per line. It displays messages about the state of the system, including error codes. Figure 1-2. on page 22, describes the symbols representing the different system activities. For information about error codes, refer to Chapter 3 , “troubleshooting,” on page 47.

system power switch

Use the Power switch to power the system unit on and off. When you use the soft power down procedure, the HP workstations’ c-class hardware is designed to produce the proper diagnostic and self test messages, and broadcasts a warning message to remote terminals that it is about to shutdown. The operating system executes an automatic shutdown -q command. Turning the power switch back on again automatically boots up the HP-UX operating system if the system has been conﬁgured to auto boot. For information on setting auto boot, refer to the section “setting the auto boot and auto search ﬂags” on page 178.

storage device controls and features

This workstation allows either or both of the following internal storage devices: CD drive or ﬂoppy disk drive. The following sections describe the controls and features of these devices.

NOTE

Figure 1-3. shows the operating controls and features of the CD drive, and Table 1-1. describes those controls and features.

You cannot have two internal storage devices of the same type. For example, you cannot have two ﬂoppy disk drives, and you cannot have two CDROMs.

security lock

Access to the mass storage devices is controlled by a security lock on the front panel. Locking the workstation front panel minimizes potential unauthorized user access.

To prevent access to internal components requires the use of the security loop on the rear panel of the workstation. See “unit rear panel controls.”

System Unit Rear Panel Connectors

audio connectors

The HP workstation c-class has audio-input and -output capabilities through external input and output connectors on the rear panel and through an internal speaker. The sound is 16-bit, 44 kHz (CD-quality).

The rear panel contains the Audio IN (Stereo line-in) and Microphone (Mic-in), and Audio OUT (Stereo line-out) and Headphones (headphone-out) connectors. This workstation also has a mono internal speaker.

The audio connectors are standard stereo audio mini-jacks (see Figure 1-6).

NOTE

Hewlett-Packard recommends using gold-plated plugs available through audio retailers for best quality recording and playback through the external connectors.

USB connectors

The USB connectors located on the rear panel of the workstation provide an interface for the keyboard and mouse to the system. These USB connectors support only the HP keyboard, scroll mouse and hub. The keyboard and mouse may be plugged into the rear of the workstation or plugged into the USB hub. No other USB conﬁguration is currently supported. Consult the documentation that accompanies each input device for speciﬁc information concerning its use.

For more information on the Universal Serial Bus, refer to the following URL:

http://www.usb.org

CAUTION

Usage of devices other than USB speciﬁcation may result in unpredictable functionality and inferior performance of the HP workstation c-class.

NOTE

The USB clip on the rear of the chassis provides strain relief for the USB cables.

hp parallel i/o connector

The 25-pin HP Parallel I/O interface uses IEEE 1284 I/O interface protocols to support peripheral devices such as printers and plotters. Consult the documentation that accompanies each peripheral device for speciﬁc information concerning its use.

802.3 network connectors

The HP workstation c-class has a built-in Twisted Pair (TP) connector for the 802.3 (ETHERNET) or 10BaseT/100BaseT network. Connections to ThinLAN networks require

an external transceiver. The workstation automatically selects the correct network setting.

RS-232 serial input/output connectors

There are a variety of peripheral devices that can attach to the RS-232 Serial Input/Output (SIO) ports on this workstation. Refer to the label on the rear of the workstation to locate serial port 1 and serial port 2. Peripheral devices include printers, plotters, modems, and scanners. Consult the documentation that accompanies each peripheral device for speciﬁc information concerning its use.

The SIO ports are programmable, allowing functions such as bit rate, character length, parity, and stop bits to be set using the System Administration Manager (SAM) or by selecting a system special device ﬁle with the functions already programmed. The SIO Ports are used as interfaces for serial asynchronous devices to the CPU.

Table 1-4. shows the SIO connector pin listings. The serial connectors are 9-pin D-sub connectors. Signal names are those speciﬁed in the EIA RS-232 standard.

SCSI connectors

The c-class workstation has built in SCSI connectors for Ultra2 Wide Low-Voltage Differential (LVD) SCSI and Ultra Narrow Single-Ended (NSE) SCSI. Use the SCSI connectors to connect external SCSI devices such as DDS-format tape drives and CD-ROM drives. Consult the documentation that accompanies each SCSI device for speciﬁc information concerning its use. Refer to Appendix B, SCSI Connections, for information about connecting SCSI devices to your workstation.

NOTE

There must ALWAYS be a terminator at both ends of a SCSI bus. This means one internal terminator and one external terminator.

TOC button

The TOC (transfer of control) button interrupts the system and transfers control from the default device to an auxiliary device. A transfer of control saves the state of the processor in Processor Internal Memory (PIM) and begins execution of recovery software at a nonzero location speciﬁed by a special location in Page Zero called MEM_TOC. The TOC code is protected by a checksum.

power cord connector

Plug the workstation’s power cord into the power cord connector to provide AC power to the system.

security loop

The security loop provides a means of locking the left side panel with a padlock or other locking device to prevent unauthorized access. To operate the security loop:

1. Inspect left side panel for proper seating in the mainframe chassis.

2. Push in the retractable pin on the spring loaded square fastener.

3. Insert the locking device through the top and bottom holes of the square fastener.

4. Inspect after locking device is in place to assure that the retractable pin is captured in the side panel insert hole.

The internal components of the workstation is now secured. See Figure 1-7. on page 30.

NOTE

A locking device is not supplied with the workstation; the customer must supply a lock to use with the security loop.
