SentinelRAID 170 Installation and Hardware Reference Manual
2-2 Hardware Installation Preparation
♦ Working surface: Provide a soft, clean surface on which to place your controller
before working on it. Servicing on a rough surface may damage or scratch the
enclosure.
2.3.2 Static-free Installation
Static electricity can damage the electronic components of the system. Most of the
controllers that are returned for repair are the result of improper installation and ESD
damage. To prevent ESD damage, follow these precautions before touching or handling
any of the components:
♦ When installing the SR 170, you should wear an anti-static wrist band or touch a
grounded metal surface to discharge any static electricity form your body.
♦ Avoid carpets, plastic, vinyl, or styrofoam in the work area.
♦ Handle any components by holding its edges or metal frame. Avoid touching PCB
boards or connector pins.
2.4. Hardware Installation Preparation
2.4.1 Tools or Equipment Needed for Installing the Subsystem
The only tools necessary are #2 cross-head Phillips and 3/16-inch slotted screwdrivers.
2.4.2 Planning Before Installation
♦ Module locations: Make sure you are aware of the related positions of each plug-in
module and interface.
♦ I/O path configurations: The SR controllers have four SCSI-320 I/O channels
interfaced through four SCSI ports. The installation of an optional daughter board
increases the available SCSI-320 I/O channels by four. All I/O channels can be
configured as either host or drive channels.
♦ I/O port cabling: All series models are equipped with 0.8mm VHDCI SCSI
connectors. Please contact Infortrend technical support for an updated list of host
adapters that have been tested and proved compatible with the SR controller series.
♦ Power supplies: Two power cord connectors ensure that redundant power supplies
can be connected to the SR controller so that in the event that one power supply fails,
the second power supply will continue to supply sufficient power to run the SR
controller.
