This chapter contains a checklist of the activities required to prepare for the arrival and installation of an SGI computer system, followed by details of the checklist items.
Some installations are simple enough that it isn't necessary to explicitly go through all the actions in the checklist. In other installations, the checklist can help you to organize the many tasks that need attention. Those responsible for the installation must decide into which category their particular installation fits.
For a detailed discussion of most of the items mentioned in this chapter, refer to Chapter 2, “Site Preparation Concepts”, and to the chassis-specific chapters (chapters 3 through 8).
This chapter provides a step-by-step process to help you organize complex installations.
Read this chapter for an overview of site preparation activities, and then use Table 1-1 to track progress for your particular location and system. The rest of this guide provides specific details, many of which are relevant to the installation.
The extent of site preparation tasks depends on the size and complexity of the system. A few small systems are easily installed with little or no modification to the existing site. Large systems, or numerous small systems, require more preparation, with their greater requirements for power, air conditioning, and so on. When installing a system, keep in mind how it fits in with the rest of the equipment installed at that site.
Some sites require that you have specialized knowledge to plan and install services such as power, air conditioning, and safety equipment. Always follow local and regional codes and recommendations while performing activities under regulation. When using consultants, verify that they are licensed and knowledgeable about local regulations.
Site preparation also involves thinking about the future. As configurations grow, site requirements change. While planning a site, consider how and when the site will need modification, and plan accordingly. Make sure the infrastructure being installed (power, air conditioning, and so on) can support future expansion plans.
To minimize mistakes and unforeseen situations for complex sites, assign one person as a coordinator to read this guide and assign tasks. Table 1-1 is only a guideline and cannot cover all circumstances involved in site preparation. Also, many activities are interdependent and involve compromises. After the coordinator evaluates the dependencies and compromises, this guide can be divided among several people so that multiple activities can be performed at the same time.
Start with the activities that take the longest time. Pay particular attention to activities that involve dependency on others, such as having an electrician install power circuits, and to items that are expensive to change in the future.
When you have completed the activities outlined in Table 1-1, the site is prepared and is ready to receive the system. To proceed, refer to the installation instructions provided for the system. See “ Additional Documentation” for the source of additional documents.
See “Site Preparation Checklist Details” for details about these items.
Table 1-1. Site Preparation Checklist
Verify intended site
EMI, ESD, vibration, acoustics
Install power and air conditioning
Determine power requirements
Read grounding section (“Chassis Branch Circuit Grounding” in Appendix B
Install power circuits (if required)
Install safety and protection equipment
Determine thermal load
Install air conditioning (if required)
Prepare physical location
Terminal, monitor, keyboard, mouse
Prepare to receive shipment
Determine size & weight of items
Locate required tools (see Table 1-2
Arrange assistance to move large items
Prepare for external cabling
Serial terminals and/or video monitors
Keyboards and mice
This section provides additional details about the items in Table 1-1, and gives references to sources of further information.
Make sure the system can be safely transported to the intended site, and that it will fit once it gets there. Refer to “Physical Location” in Chapter 2 and the individual chassis chapters (chapters 3 through 8) for detailed site requirements.
Make sure the intended site does not have any unusual EMI or ESD problems. See “Electromagnetic Interference” in Chapter 2 and “Electrostatic Discharge” in Chapter 2 for more information.
Make sure that the intended site falls within the vibration limits for the system to be installed. Refer to the tables in the individual chassis chapters (chapters 3 through 8) to determine these limits. If the intended site exceeds these limits, take corrective action.
Make sure the acoustic output of the planned installation does not present a problem. Refer to “Acoustics” in Chapter 2 and the individual chassis chapters (chapters 3 through 8) to determine the acoustic output of the planned systems. If these totals present a problem, take corrective action.
Determine the power and wiring requirements of the site using the information supplied in “ Electrical Requirements” in Chapter 2, the individual chassis chapters (chapters 3 through 8), and Appendix B, “Site Power and Power Cables”.
Read “Chassis Branch Circuit Grounding” in Appendix B to ensure that the site fully meets the very important requirements described there.
If the existing site wiring does not support the planned installation, arrange for the wiring to be upgraded.
Read Appendix C, “Safety and Protection Equipment”, and install any necessary upgrades.
Determine the air conditioning requirements (thermal load) for the site using the information supplied in “ Thermal Requirements” in Chapter 2 and in the individual chassis chapters (chapters 3 through 8).
If the existing site air conditioning does not support the planned installation, arrange for the air conditioning to be upgraded.
Arrange adequate space for the delivery and installation of the systems using the information supplied in “Physical Location” in Chapter 2 and the shipping dimensions listed in the individual chassis chapters (chapters 3 through 8).
Arrange for any required external peripherals, such as terminals, monitors, keyboards, mice, SCSI devices, and so on, using the information supplied in Appendix A, “Site Preparation for External Peripherals”.
Consider the size and weight of the shipping cartons listed in the individual chassis chapters (chapters 3 through 8), and make any necessary preparations to receive them. Also read “Physical Location” in Chapter 2.
Refer to Table 1-2 to determine the tools needed for each listed activity.
Table 1-2. Tools Useful for Receiving and Installing Systems
Pallet jack with 22” fork spacing (up to 200 lb).
Forklift (can require up to a 1,000-lb capacity).
Opening shipping cartons or crates
Knife (to cut strapping bands).
Gloves (protection from crate splinters).
Knife (to cut packing tape).
Low-profile dolly that keeps chassis vertical;
Usually no tools are required.
Stabilizing chassis (seismic protection)
Stabilizers to screw into 1/4”-20 UNC threads on chassis underside.
Stabilizers to replace leveler feet in M12 x 1.75 threads on chassis underside.
Small slothead and cross-recess screwdrivers.
Arrange for assistance moving large items. In particular, assistance is recommended when
receiving a large shipment
uncrating a rack chassis
moving a rack chassis.
|Caution: Always use assistance when moving equipment up or down ramps. For rack systems, use a minimum of three individuals. On fully configured systems, up to five people may be required to move the chassis safely. Avoid ramps that exceed a 20° angle.|
Read the individual chassis chapters (chapters 3 through 8) to determine which local devices may be installed, then make any necessary arrangements. Also see Appendix A, “Site Preparation for External Peripherals”.Appendix A, “Site Preparation for External Peripherals”
