Introduction
Chapter 1: Introduction
Scope
This Users Manual covers the RAIDstation7 Ultra160 SCSI Storage Arrays and
their associated optional and replacement products.
Configurations
The RAIDstation7 Ultra160 SCSI Storage Array is available in an AC-powered
tower (RS/7U160 KIT) or 19”rackmount (RS/7U160R KIT) model.
Each Storage Array consists of 9 storage bays: seven for hard disk drives and two
for power supplies. The rackmount models can be mounted in any standard 19-
inch equipment rack. It is also possible to daisy-chain two Storage Arrays.
Models covered by this Users Manual
•RS/7U160 KIT
•RS/7U160R KIT

Introduction
RAIDStation7 Ultra160 SCSI Tower
The tower model contains two power supply units, a maximum of seven SCSI
hard disk drives, three Advanced Cooling Modules (ACM’s), a Versatile Environ-
mental Monitor (VEM), and a single Ultra160 Wide SCSI bus. The tower Storage
Array is connected to the host system using the included 16-bit LVD SCSI cable.

Introduction
RAIDStation7 Ultra160 SCSI Rackmount
The RAIDStation7 rackmount model can be mounted in any standard equipment
rack with a front width of 19 inches. The procedure for mounting the rackmount
Storage Array in the equipment rack is described in Chapter 2.
The rackmount Storage Array consists of two power supply units, a maximum of
seven SCSI hard disk drives, three Advanced Cooling Modules (ACM’s), a Ver-
satile Environmental Monitor (VEM), and a single Ultra160 Wide SCSI bus. The
rackmount Storage Array is connected to the host system using the included 16-
bit LVD SCSI cable.

Introduction
Device Carriers
Front loaded components such as disk drives and power supplies are housed in
easily removable device carriers. The device carrier is the basic building block of
the series. The device carriers are of high quality anodized metal construction.
This allows for rapid heat dissipation and conforms to the stringent requirements
of CE and FCC standards. A release mechanism ensures the safe and easy inser-
tion and removal of the device carrier. Disk drive and power supply carriers can
be differentiated by the color of their ejection button. The ejection button on the
disk drive is gray and on the power supply is black.
Cooling
The RAIDStation7 Ultra160 SCSI Storage Array models feature three Advanced
Cooling Modules (ACMs). The modules are mounted at the rear of the unit. In the
event of an ACM failure, the remaining two ACMs are capable of cooling the
entire Storage Array until the failed ACM is replaced. This gives N+1 redun-
dancy.
Environmental Monitoring
The Versatile Environmental Monitor (VEM) monitors the ACMs, hard disk
drives, power supplies, and Storage Array shelf temperature.
The device carriers has two LEDs on the front which give information about the
status of the hard disk drives or power supplies.

Introduction
Power Supplies
The RAIDStation7 Ultra160 Storage Array is an AC-powered unit. The power
supply is described below.
AC Power Supply
The RAIDStation7 Ultra160 Storage Array uses two high performance, hot swap
power supply units. A single power supply is rated at 370 Watts peak. Each
power supply has greater than 500,000 hours Mean Time Between Failures
(MTBF). In the event one power supply fails, the second power supply can easily
power the entire Storage Array until the failed unit is replaced. A diagram of the
power supply unit is shown in Figure 1-3.

Unpacking and Initial Setup
Chapter 2: Unpacking and Initial Setup
On receipt, visually inspect the exterior of the packaging for any signs of damage.
If any damage is found the carrier and Adaptec must be notified immediately, and
they will advise you of the appropriate action. The cartons are sealed using pack-
aging tape which should be cut open in the normal manner. Remove the top foam
layer from each box and exercise caution when lifting out the components. At this
point the contents should be verified against the packing list and Adaptec should
again be notified if any discrepancies exist. The devices and power supply units
are packaged in anti-static packaging and anti-static precautions must be
observed prior to removal and during handling.
CAUTION: This equipment is intended only for installation in a
restricted access location.

Unpacking and Initial Setup
Rackmounting Recommendations
To ensure the safe and efficient operation of the RAIDStation7 Ultra160 SCSI
rackmount Storage Array it is essential that you comply with the following guide-
lines. Adaptec’s rackmount systems may be installed in closed or open rackmount
cabinets by observing the environmental, electrical and mechanical precautions
listed in the following sections.
Ambient Temperature
Installation of rackmount systems in standard 19 in. cabinets may lead to a differ-
ential between the room ambient temperature and the internal ambient tempera-
ture of the rack environment. The normal operating temperature of the
RAIDStation7 Ultra160 SCSI Storage Array is between 5oC and 30oC (between
41oF and 86oF). The maximum operating temperature of the RAIDStation7
Ultra160 SCSI Storage Array is 40 degrees centigrade (104 degrees fahrenheit).
However, it is not recommended that the system be continuously run at this ele-
vated temperature. Room ambient temperature must be compatible with this rec-
ommendation.
Air Flow
To ensure that the RAIDStation7’s internal heat build-up is adequately dissipated
into the room environment, the Storage Array’s air flow must not be restricted.
No air vents should be blocked. The Storage Array must be a minimum of 1 meter
away from a solid surface such as a wall or partition. Air flow through the
RAIDStation7 Ultra160 SCSI Storage Array is from front to rear.
Mechanical Stability
Consideration should be given to the loading of the cabinet. To maintain a low
center of gravity (thus reducing the likelihood of instability and equipment tip-
ping) rackmount Storage Arrays should be installed (where possible) from the
bottom of the cabinet upwards. This is recommended to ensure personal safety.

2-3
Unpacking and Initial Setup
Electrical Considerations
Circuit Overloading
Care should be taken to ensure that the current does not exceed the rating of the
power source circuitry. This includes cabling, power distributions, filters and any
other components through which the main AC flows. The power requirements of
the RAIDstation7 Ultra160 SCSI Storage Array (both tower and rackmount) is
given in Table 2-1.
These power requirements must be added to the power demands of any other
electrical devices installed in the equipment rack to calculate the total power con-
sumption of the complete system. In addition, any surge currents must be consid-
ered. Hard disk drives normally consume greater than twice the amount of current
at start-up time than they use during steady state operation.
Grounding
Adaptec recommends that all rackmount Storage Array shelves be grounded to a
common point in the equipment rack. Each shelf should have a grounding braid
running from it to this common grounding point (see Figure 2-1). A point for
securing the grounding braid is provided at the rear of the Adaptec rackmount
cabinets.
