3	Hardware Installation
3.1	Introduction
	This chapter gives detailed instructions on how to install the subsystem. When installing the
	subsystem, it is necessary to mount the chassis into a rack or cabinet and to install hard
	drives and drive trays. Installation into a rack or cabinet should occur before the hard drives or
	drive trays are installed into the subsystem. Please confirm that you received all of the compo-
	nents listed on the Unpacking List that came with the subsystem before proceeding with the
	installation process.
	CAUTION!
	Please note that the installation instructions described in this manual should be carefully fol-
	lowed to prevent any difficulties and damages to your system.
3.2	Installation Prerequisites
	1.	Static-free installation environment: The RAID subsystem must be installed in a static-free
		environment to minimize the possibility of electrostatic discharge (ESD) damage. (See
		Section 3.3.2 Static-free Installation )
	2.	Component check: Before installing the RAID subsystem, you should first check to see
		that you have received all the required components. (See Section 3.5 Unpacking the Sub-
		system) If any items appear damaged, contact your vendor for a replacement.
	3.	Cabling: The RAID models all come with one (1) audio-jack-to-DB9 cable to facilitate the
		connection of the COM port for terminal emulation management. Two (2) power cords
		are provided for the power connections to the power sources. The RJ-45 cables for host
		and external devices connections are user-supplied. Please see Section 5 Subsystem Con-
		nection and Operation for sample topologies and configuration options.
	4.	Memory module: If you wish to change the pre-installed memory module, a separately pur-
		chased module must be installed. (See Section 6.3 DIMM Module Replacement)
	5.	Rack installation: The enclosure chassis can be installed into rack cabinet using separately
		purchased mounting rails, rear-attached brackets, or Bosch’s slide rails (see
		Section 3.6 Rack/Cabinet Installation).
3.3	Safety Precautions
3.3.1	Precautions and Instructions
	1.	Be sure the correct power range (100-120 or 220-240VAC) is supplied by your rack cabi-
		net or power outlet.
	2.	Thermal notice: All drive trays (even if they do not contain a hard drive) must be installed
		into the enclosure. Leaving a drive bay or module slot open will severely affect the airflow
		efficiency within the enclosure, and will consequently lead to system overheating. Keep a
		faulty module in place until you have a replacement unit and you are ready to replace it.
	3.	An enclosure without disk drives can weigh over 24 kilograms. Two (2) people are
		required to install or relocate the subsystem. Drives should be removed from the enclo-
		sure before moving the subsystem.
	4.	Airflow considerations: The subsystem requires an airflow clearance especially on the
		front and rear. For proper ventilation, a minimum of 2.5cm is required between the front

of the enclosure and rack cover; a minimum of 5cm is required between the enclosure and end of the rack.
