3 Routine care, SATA drive guidelines, and disassembly preparation This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service. CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board. The power cord must be disconnected from the power source before opening the computer to prevent system board or component damage.
Preventing electrostatic damage to equipment Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to electric components and accessories. ● To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes. ● Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers or packaging.
Recommended materials and equipment The following grounding equipment is recommended to prevent electrostatic damage: ● Antistatic tape ● Antistatic smocks, aprons, or sleeve protectors ● Conductive bins and other assembly or soldering aids ● Conductive foam ● Conductive tabletop workstations with ground cords of one-megohm +/- 10% resistance ● Static-dissipative table or floor mats with hard ties to ground ● Field service kits ● Static awareness labels ● Wrist straps and footwear straps pr
● Never cover the ventilation slots on the monitor with any type of material. ● Install or enable power management functions of the operating system or other software, including sleep states. Routine care General cleaning safety precautions 1. Never use solvents or flammable solutions to clean the computer. 2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component. 3.
● Visible debris underneath or between the keys may be removed by vacuuming or shaking. ● Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too much air pressure can dislodge lubricants applied under the wide keys. ● If you want to remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronics supply outlets. CAUTION: Never remove a wide, level key (like the space bar) from the keyboard.
Cables and connectors Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid bending or twisting the cables, and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced.

D Linux technical notes HP offers a variety of Linux solutions for HP workstation customers: ● HP supports Ubuntu on some HP workstations. ● HP supports Red Hat Enterprise Linux (RHEL) on HP workstations. ● HP certifies and supports SUSE Linux Enterprise Desktop (SLED) on HP workstations. For Linux setup and restore procedures, see the user guide for your workstation at http://www.hp.com/ support/ workstation_manuals.
Audio All HP workstations come with built-in audio hardware. The audio hardware is supported by the Advanced Linux Sound Architecture (ALSA) drivers included with all modern Linux distributions. The audio hardware provides basic playback and recording features. The ability to simultaneously play audio from multiple sources, such as applications and CDs, is provided in the ALSA driver that provides audio mixing. The performance of software audio mixing and playback is greatly improved in ALSA version 1.0.
NVIDIA graphics workstations Some workstation configurations come with NVIDIA Quadro graphics hardware. HP recommends the use of NVIDIA drivers for best results on Linux systems. HP provides recommended versions of the drivers with RPM-compatible installers for RHEL and SLED distributions. These are available from the HP Installer Kit for Linux and from workstation driver repositories on hp.com. When HP installers are used, their contents and documentation links are located in the /opt/hp/ nvidia folder.
AMD graphics workstations Some workstation configurations include AMD graphics hardware. The supported Linux distributions should all have some “in-box” driver that supports the hardware well enough for the X server to run. Here are some of the Xorg drivers that may be loaded as the server starts: ● The Radeon in-box X driver will associate with some older GPUs. ● The fbdev or vesa X driver may activate for certain other cards.
