Rack System Precautions
The following safety requirements must be considered when the unit is mounted in a rack.
• The rack design should incorporate stabilizing features suitable to prevent the rack from tipping or
being pushed over during installation or in normal use.
• When loading a rack with the units, fill the rack from the bottom up and empty from the top down.
• The rack should comply with the airflow requirements detailed in the technical specification.
• The rack design should take into consideration the maximum operating ambient temperature for the
unit, which is 40°C when dual cooling modules are fitted.
• The rack should have a safe electrical distribution system. it must provide overcurrent protection for
the unit and must not be overloaded by the total number of units installed in the rack. Consideration
of the electrical power consumption rating shown on the nameplate should be used when
addressing these concerns.
• The electrical distribution system must provide a reliable earth for each unit and the rack.
Preface
• Each power supply in each unit has an earth leakage current of 0.65mA. The design of the electrical
distribution system must take into consideration the total earth leakage current from all the power
supplies in all the units. The rack will require labelling with "HIGH LEAKAGE CURRENT. Earth
connection essential before connecting supply".
• The rack when configured with the units must meet the safety requirements of UL1950 and IEC
60950.

Data Security
• Power down your host computer and all attached peripheral devices before beginning installation.
• Each enclosure contains up to 16 removable disk drive modules. Disk units are fragile. Handle them
with care, and keep them away from strong magnetic fields.
• All the supplied plug-in modules and blanking plates must be in place for the air to flow correctly
around the enclosure and also to complete the internal circuitry.
• If the Subsystem is used with modules or blanking plates missing for more than a few minutes, the
enclosure can overheat, causing power failure and data loss. Such use may also invalidate the
warranty.
• If you remove any drive module, you may lose data.
– If you remove a drive module, replace it immediately. If it is faulty, replace it with a drive module
of the same type and capacity
• Ensure that all disk drives are removed from the enclosure before attempting to manhandle or move
the rack installation.
• Do not abandon your backup routines. No system is completely foolproof.

1.2 The Enclosure Core Product
1.2.1 Enclosure Chassis
The Galaxy 65 design concept is based on a Subsystem together with a set of plug-in modules. The
Galaxy 65 Subsystem as supplied comprises:
• Chassis and Backplane with integral Operators Panel.
• Power Supply/Cooling plug-in modules, auto-ranging, 475W, AC (see Figure 1–5)
• FC-AL Drive Carrier Modules and associated dummy carrier modules (See Figure 1–10).
• FC-AL LRC 2Gb/s Input/Output Modules with integrated Rorke Data Galaxy 65 RAID controllers,
known as Storage Managers.(See Figure 1–8).
The chassis consists of a sheet metal enclosure assembly containing a Backplane PCB and module
runner system. This chassis assembly also includes an integral Operators (Ops) Panel mounted at the
rear.
The chassis assembly contains 16 drive bays at the front, each of which accommodates a plug-in drive
carrier module. The 16 drive bays are arranged in 4 rows of 4 drives. At the rear, the chassis assembly
contains 5 module bays to house two Power Supply/Cooling modules, two LRC I/O modules and the
integral Ops panel.
The Backplane PCB provides logic level signal and low voltage power distribution paths. Figure 1–2 and
Figure 1–3 show front and rear views of an Galaxy 65 chassis respectively.
The 4 x 4 chassis is fitted with 19 inch Rack mounting features which enables it to be fitted to standard
19 inch racks and uses 3EIA units of rack space.
• A Bay is defined as the space required to house a single 1.0" high 3.5 inch disk drive in its carrier
module. e.g. a 1 x 4 bay module would take the space of 1 drive width by 4 drive bays high (in rack
mount configuration).

1.3 The Plug-in Modules
1.3.1 Power Supply/Cooling Module
A Galaxy 65 Enclosure requires one or more of the following modules for normal operation:
Two Power Supply/Cooling modules (Figure 1–5) are supplied mounted in the rear of the enclosure as
part of the Subsystem core product.
Figure 1–5 AC Power Supply/Cooling Module
.
PSU voltage operating ranges are nominally 115V or 230V AC, selected automatically.
.
Four LEDs mounted on the front panel of the Power Supply/Cooling Module indicate the status of the PSU
and the fans.
Warning The Power Supply/Cooling module is not an operator removable part. It should only be removed
by a technician who has knowledge of the hazards present within the module.
4
1.3.1.1 Multiple Power Supply/Cooling Modules
The Galaxy 65 system must always be operated with two Power Supply/Cooling modules fitted. The two
Power Supply/Cooling modules operate together so that if one fails the other maintains the power supply
and cooling while you replace the faulty unit.
Module replacement should only take a few minutes to perform but must be completed within 5 minutes
from removal of the failed module.
1.3.2 Operators Panel
Supplied as an integral part of the Enclosure core product, a typical Operators (Ops) Panel is shown in
Figure 1–6.
Introduction
Figure 1–6 Operators (Ops) Panel
The Ops Panel provides the enclosure with a micro controller which is used to monitor and control all
elements of the Enclosure.
1.3.2.1 Ops Panel Indicators and Switches
The Ops Panel includes Light Emitting Diodes (LEDs) which show the status for all modules, an Audible
Alarm which indicates when a fault state is present, a push-button Alarm Mute switch and a thumb wheel
SEL_ID address Range selector switch.
The Ops Panel switch functions are shown in Table 1–1.
Important Switch settings are only read at Power On.
The Galaxy 65 enclosure ID must always be set to select ID1.

1.3.3 Loop Resiliency Circuit Input/Output Module (FC-AL)
The Galaxy 65 storage Subsystem includes an enclosure with rear facing bays which house two Loop
Resiliency Circuit (LRC) I/O modules with integrated Rorke Data
Storage Managers (SM) modules. (see Figure 1–3)
The FC-AL Backplane incorporates two independent loops formed by Port Bypass Circuits within the LRC
I/O modules.
The plug-in SM modules have been designed for integration into a Galaxy 65 storage Subsystem, utilizing
FCAL interfacing with the host computer system.
Processors housed on the LRC modules provide enclosure management and interface to devices on the
Backplane, PSU, LRC and Ops Panel, to monitor internal functions. These processors operate in a
master slave configuration to allow failover.
The module incorporates the following LED indicators, shown in Figure 1–7:
• Host Port 0 Signal Good (Green)
• Host Port 1 Signal Good (Green)
• Expansion Port 0 Rx Good (Green)

1.3.4 Drive Carrier Module
The Drive Carrier module comprises a hard disk mounted in a carrier. Each drive bay will house a single
1.0 inch high, 3.5 inch disk drive in its carrier.
Each disk drive is enclosed in a die-cast aluminum carrier which provides excellent thermal conduction,
radio frequency and electro-magnetic induction protection and affords the drive maximum physical
protection.
The front cap also supports an ergonomic handle which provides the following functions:
• Camming of carrier into and out of drive bays.
• Positive 'spring loading' of the drive/backplane connector.
• An anti-tamper lock operated by a torx socket type key.

1.3.4.2 Anti-tamper Locks
Each drive carrier incorporates two indicators, an upper (Green) and lower (Amber). In normal operation
the green indicator will be ON and will flicker as the drive operates.
Anti-tamper locks are fitted in the drive carrier handles (Figure 1–11) and are provided to disable the
normal ‘pinch' latch action of the carrier handle.
Figure 1–11
Anti-tamper Lock
1.3.5 Dummy Carrier Modules
Dummy carrier modules are provided for fitting in all unused drive bays. They are designed as integral
drive module front caps with handles and must be fitted to all unused drive bays to maintain a balanced
airflow.
Warning Operation of the Enclosure with ANY modules missing will disrupt the airflow and the drives will
not receive sufficient cooling. It is ESSENTIAL that all apertures are filled before operating the
unit. Dummy Carriers are available for this purpose.
1.4 Visible and Audible Alarms
The functional modules have associated status LEDs. The Ops Panel shows a consolidated status for all
modules.
LEDs show constant green for good or positive indication. Constant Amber LEDs indicate there is a fault
present within that module.
The Ops Panel also incorporates an Audible Alarm to indicate when a fault state is present and also an
Alarm Mute push-button.
Warning The Ops Panel is an integral part of the enclosure chassis assembly and can only be replaced by
trained personnel.
