To prevent such damage from occurring, observe the following precautions during board unpacking and installation: • Stand on a static-free mat. • Wear a static strap to ensure that any accumulated electrostatic charge is discharged from your body to ground. • Connect all equipment together, including the static-free mat, static strap, routing nodes, and peripheral units. • Keep uninstalled printed circuit boards in their protective antistatic bags. • Handle printed circuit boards by their edges, once you have removed them from their protective antistatic bags. Safety and Regulatory Statements Safety Statement Safety Statement This equipment conforms to the following safety standards: • UL 1950 • CSA 950 • IEC 950 • EN 60950 Safety and Regulatory Statements Laser Safety Statement (U.S.A. Only) Laser Safety Statement (U.S.A. Only) The CD ROM mass-storage system is certified as a Class-1 laser product under the U.S. Department of Health and Human Services (DHHS) Radiation Performance Standard according to the Radiation Control for Health and Safety Act of 1968. This means that the mass-storage system does not produce hazardous laser radiation. Because laser light emitted inside the mass-storage system is completely confined within protective housings and external covers, the laser beam cannot escape from the machine during any phase of user operation. Visible LEDs The visible LED on this product is classified as “Class 1 LED PRODUCT” in accordance with EN 60825-1.

It presents the information in the following sections: • Checking the SCSI IDs • Preparing your workstation • Installing storage devices • Removing the main tray assembly • Replacing the main tray assembly • Installing additional memory • Installing the EGRAM module • Installing an EISA, PCI, or GSC option board • Changing your monitor type NOTICE: Your workstation shipped with a package of extra disk slides. Keep the slides in a safe place, you will need them when you add new devices to the storage tray. CAUTION: Always wear a properly grounded wrist strap when reconfiguring your workstation. Use the following tools to remove or replace hardware parts when changing your configuration: • Light-duty flatblade screwdriver with 150 mm (6 inch) blade • Needlenose pliers Also, read the ESD Precautions in Appendix A of this guide. 100 Changing Your Workstation’s Hardware Configuration Checking the SCSI IDs Checking the SCSI IDs To determine which SCSI IDs are currently in use on your system, use the ioscan command in a terminal window: 1 At a command line prompt, enter the following at the prompt: /usr/sbin/ioscan -f After a few moments the ioscan utility lists all of the SCSI I/O devices it could find. The list appears similar to the following: Class I H/W Path Driver S/W State H/W Type Description ============================================================================================= bc 0 root CLAIMED BUS_NEXUS bc 1 8 ccio CLAIMED BUS_NEXUS I/O Adapter ext_bus 0 8/0 c720 CLAIMED INTERFACE GSC built-in Fast/Wide SCSI Interface target 0 8/0.0 tgt CLAIMED DEVICE disk 3 8/0.0.0 sdisk CLAIMED DEVICE QUANTUM LPS1080WD target 1 8/0.5 tgt CLAIMED DEVICE disk 2 8/0.5.0 sdisk CLAIMED DEVICE DEC DSP3210SW target 2 8/0.6 tgt CLAIMED DEVICE disk 0 8/0.6.0 sdisk CLAIMED DEVICE DEC DSP3210SW ba 0 8/16 bus_adapterCLAIMED BUS_NEXUS Core I/O Adapter ext_bus 2 8/16/0 CentIf CLAIMED INTERFACE Built-in Parallel Interface audio 0 8/16/1 audio CLAIMED INTERFACE Built-in Audio tty 0 8/16/4 asio0 CLAIMED INTERFACE Built-in RS-232C ext_bus 1 8/16/5 c700 CLAIMED INTERFACE Built-in SCSI target 3 8/16/5.2 tgt CLAIMED DEVICE disk 1 8/16/5.2.0 sdisk CLAIMED DEVICE TOSHIBA CD-ROM XM-4101TA target 4 8/16/5.3 tgt CLAIMED DEVICE tape 0 8/16/5.3.0 stape CLAIMED DEVICE HP HP35480A target 5 8/16/5.4 tgt CLAIMED DEVICE disk 10 8/16/5.4.0 sdisk CLAIMED DEVICE SEAGATE ST3600N target 6 8/16/5.6 tgt CLAIMED DEVICE disk 5 8/16/5.6.0 sdisk CLAIMED DEVICE MICROP 2112 lan 0 8/16/6 lan2 CLAIMED INTERFACE Built-in LAN ps2 0 8/16/7 ps2 CLAIMED INTERFACE Built-in Keyboard/Mouse bc 2 10 ccio CLAIMED BUS_NEXUS I/O Adapter ext_bus 3 10/12 c720 CLAIMED INTERFACE GSC Fast/WideSCSI Interface target 7 10/12.4 tgt CLAIMED DEVICE disk 6 10/12.4.0 sdisk CLAIMED DEVICE SEAGATE ST31200W graphics 2 10/16 graph3 CLAIMED INTERFACE Graphics ba 1 8/20 bus_adapterCLAIMED BUS_NEXUS Core I/O Adapter hil 0 8/20/1 hil CLAIMED INTERFACE Built-in HIL tty 1 8/20/2 asio0 CLAIMED INTERFACE Built-in RS-232C ba 2 8/20/5 eisa CLAIMED BUS_NEXUS EISA Bus Adapter ext_bus 4 8/20/5/3 hshpib CLAIMED INTERFACE EISA card HWP0C70 target 8 8/20/5/3.0 tgt CLAIMED DEVICE target 9 8/20/5/3.1 tgt CLAIMED DEVICE targe...
