1 Introduction ! Introduction ! System Rack Models ! Configurator Assistant ! 42U System Rack ! Multi-Bay System Rack
Introduction The system rack is an attractive enclosure designed to store and protect your server components. The system rack allows you to integrate your server, monitor, and other components in one cabinet that may be installed in a limited amount of floor space in just about any location. Removable side walls and front and rear doors ensure easy access to all installed components, while a special locking system prevents unauthorized access.
42U System Rack Figure 1-1 illustrates a typical 42U system rack enclosure, including the components that install into the rack. Table 1-1 lists and describes several system components installed in the system rack. A B C D E F G H Figure 1-1.
Table 1-1 lists the typical system rack components shown in Figure 1-1. Table 1-1. Typical System Rack Components Item Component Description A Monitor (LCD) A monitor that serves as your standard output device. B Monitor Tray Supports your monitor when installed in the rack. C Keyboard and Mouse Standard input devices. D Keyboard and Mouse Tray Supports your keyboard and mouse when installed in the rack.
Multi-Bay System Rack System racks can be quickly and easily joined together to accommodate large server configurations as shown in Figure 1-2. Figure 1-2.
2 Planning Your Site ! Equipment Location ! System Rack Placement ! Air Conditioning ! Electrical Facilities ! Grounding Requirements
Equipment Location When planning your facilities, the following guidelines must be considered: ! Does the allocated space allow for the proper installation of the equipment and the performance of operation and maintenance activities? ! Are the environmental conditions suitable for reliable operation? ! Is the construction of the floor appropriate for the weight of the equipment being installed? ! Will the air conditioning maintain adequate temperature and humidity conditions for the equipment being i
23.6" (600mm) 23.6" (600mm) 23.6" (600mm) 39.4" (1000mm) 39.4" (1000mm) 41.0" (1041mm) 26.3" (668mm) 39.4" (1000mm) Figure 2-1.
Environmental Conditions The location should be examined for the following environmental hazards: ! Dust - floating dust must be kept to no more than 0.3 mg/m3. Dust should be held to less than 0.15 mg/m3. ! Radio Frequency (RF) - Normally, there is no need to worry about the effect of radio frequency interference on computer operations.
Floor Construction Aspects of floor construction, such as load capacity and construction materials, must be considered when installing one or more rack systems. Note: The rack supports up to 551.2 lbs. (250 kg). Use Table 2-1 to calculate the load that each rack of your system configuration places on the floor. Table 2-1. Equipment Weight Component Weight (approx.) System Rack (42u) 253 lbs. (114.8Kg.) 66.1 lbs. (30.0Kg.) Express5800/120Ld Express5800/120Mc2 66.1 lbs. (30.0Kg.
If you do not know the load capacity of your flooring, consult your building manager or an architect. In many instances the equipment is installed directly on the existing floor and interconnecting power cables are protected by cable covers. In other instances, raised floors – that form a double floor – are used. Some advantages of raised floors are: ! Interconnecting cables can be routed under the raised floor. ! Floorboards can be easily removed to facilitate installation of cables.
System Rack Placement The system rack comes equipped with a front stabilizer that: ! steadies the rack when you extend equipment for servicing, and ! prevents creeping due to vibration. The stabilizer is predrilled to allow you to secure the system rack to the floor. Note: If preparing the area prior to the arrival of the system, review the power cable restrictions given in “Electrical Facilities” before setting any stabilizer anchors.
Figure 2-2. Distance Between Stabilizer Anchors If the rack is installed on a concrete floor, you can bolt the rack to the floor using 3/8" concrete drop-in anchors and 1½"-16 bolts. If you are installing your rack in an area with a raised floor, you can use concrete drop-in anchors and 3/8"-16 threaded rod with washers and nuts to secure the rack to the concrete beneath the raised floor. See Figure 2-3. Figure 2-3.
Air Conditioning A properly sized air conditioning system ensures stable and reliable operation of your servers by performing the following tasks: ! cooling the system ! preventing the generation of static charges ! preventing the formation of corrosion causing condensation within the system. The system rack’s temperature and humidity requirements are listed in Table 2-2. Table 2-2.
The air conditioner’s capacity must be larger than the sum of the above items. Use Table 2-3 to calculate calorific values – in BTUs. Table 2-3.
Grounding Requirements The system rack must have a dedicated ground attached to the power distribution panel. The ground wire must have an earth resistance of 100 ohms or less and depending on your local electrical code, a thickness of 38 mm2 or more. A grounding cable (12 gauge) that attaches the rack to frame (earth) ground must be used. For safety reasons, ground connections are necessary for both power distribution systems and air conditioners.
3 Planning Your System Rack Configuration ! Cabling Constraints ! Cable Summary ! Vertical Spacing ! Configuration Guidelines ! Calculating Load and Determining UPS On-Battery Run Time
This chapter helps you configure your system and determine the number of racks you will need for your system. When planning your configuration, you should consider the following guidelines: ! Does the layout violate any cable constraints? ! Is there enough rack space to accommodate all of the equipment that I have? Cabling Constraints When planning your system configuration you must consider the length of the cables that interconnect system components.
RAID Cable Restrictions RAID Host Adapters use a SCSI cable that connects each Disk Expansion Unit to its RAID Host Adapter in the Basic System Unit. Cables are available in 3.3-ft (1m) and 9.9-ft (3m) lengths. Concentrator Cable Lengths Cables for concentrator connections are available in 7-ft (2.1m) and 12-ft (3.7m) lengths. To accommodate the installation of the keyboard, mouse, and monitor on an external desktop, a 12-ft (3.
