QXS-312/324 RAID and Expansion Physical Requirements

The floor space at the installation site must be strong enough to support the combined weight of the rack, RAID chassis, expansion chassis, and any additional equipment. The site also requires sufficient space for installation, operation, and servicing of the chassis, together with sufficient ventilation to allow a free flow of air to all chassis.

Composition

The RAID chassis and expansion chassis is comprised of sheet steel that is bonded together using rivets, welding, and other forced contact methods. The metal surfaces are free from non-conductive coatings and paint.

Chassis Designators

The RAID and expansion chassis designators are as follows:

• 2U12 chassis (LFF):

• “2U12” denotes the 3.5” QXS-312 chassis (with controller or expansion modules)

• The 2U12 chassis is equipped with a drive in each drive slot

• 2U24 chassis (SFF):

• “2U24” denotes the 2.5” QXS-324 chassis (with controller or expansion modules)

• The 2U24 chassis is equipped with a drive in each drive slot

• Two controller modules or two expansion modules per chassis

• Two power supplies per chassis

Environment and Requirements

This chapter provides the following information:

• Site Requirements

• Weight and Placement Guidelines

• Electrical Guidelines

• Ventilation and Cabling Requirements

• Management Host Requirements

• RAID and Expansion Chassis Environmental Requirements

Site Requirements

The following sections provide requirements and guidelines that you must address when preparing your site for the installation.

Chapter 5

When selecting an installation site for the system, choose a location not subject to excessive heat, direct sunlight, dust, or chemical exposure. These conditions greatly reduce the system’s longevity and might void your warranty.

Chassis Power Requirements

Each chassis has two power supplies for redundancy. If full redundancy is required, use a separate power source for each module.

The AC power in each power supply is auto-ranging and is automatically configured to an input voltage range from 88 – 264 VAC with an input frequency of 47 – 63 Hz. The power supplies meet standard voltage requirements for both U.S. and international operation. The power supplies use standard industrial wiring with line-to-neutral or line-to-line power connections.

The 2U24/2U12 chassis and the high-density 4U56 chassis support DC power supplies as an alternative to using AC power supplies.

Each power cable connects one of the power supply modules to an independent, external power source. To ensure power redundancy, connect the two power cables to two separate circuits; for example, to one commercial circuit and one uninterruptible power source (UPS).

must be independent of each other, and each must be controlled by a separate circuit breaker at the power distribution point.

• The system requires voltages within minimum fluctuation. The customer-supplied facilities’

voltage must maintain a voltage with not more than ± 5 percent fluctuation. The customer facilities must also provide suitable surge protection.

• Site wiring must include an earth ground connection to the AC power source. The supply

conductors and power distribution boxes (or equivalent metal chassis) must be grounded at both ends.

• Power circuits and associated circuit breakers must provide sufficient power and overload

protection. To prevent possible damage to the AC power distribution boxes and other components in the rack, use an external, independent power source that is isolated from large switching loads (such as air conditioning motors, elevator motors, and factory loads).

Additional requirements include:

• All DC mains and supply conductors to power distribution boxes for the rack-mounted system

must comply with local, national, or other applicable government codes and regulations.

• Ensure that the voltage of your power source matches the voltage inscribed on the equipment’s

electrical label.

Weight and Placement Guidelines

Weight and placement guidelines include:

• Refer to the rackmount bracket kit installation guide pertaining to your product for guidelines

about installing chassis into the rack.

• When installing chassis into the rack, populate from the bottom position and move upwards for

optimal rack stability.

• The weight of an chassis depends on the number and type of modules installed.

• Ideally, use two people to lift a chassis. However, one person can safely lift an chassis if its weight

is reduced by removing the power supplies and drive modules.

• Do not place chassis in a vertical position. Always install and operate the chassis in a horizontal

orientation.

• When installing chassis in a rack, make sure that any surfaces over which you might move the rack

can support the weight. To prevent accidents when moving equipment, especially on sloped loading docks and up ramps to raised floors, ensure you have a sufficient number of helpers. Remove obstacles such as cables and other objects from the floor.

• To prevent the rack from tipping, and to minimize personnel injury in the event of a seismic

occurrence, securely anchor the rack to a wall or other rigid structure that is attached to both the floor and to the ceiling of the room.

Electrical Guidelines

Electrical guidelines include:

• These chassis work with single-phase power systems having an earth ground connection. To

reduce the risk of electric shock, do not plug an chassis into any other type of power system.

NOTE: Contact your facilities manager or a qualified electrician if you are not sure what type of power is supplied to your building.

• Chassis are shipped with a grounding-type (three-wire) power cord. To reduce the risk of electric

shock, always plug the cord into a grounded power outlet.

• Do not use household extension cords with the chassis. Not all power cords have the same current

ratings. Household extension cords do not have overload protection and are not meant for use with computer systems.

Ventilation and Cabling Requirements

This section includes the following information:

• Ventilation Requirements

• Cabling Requirements

Ventilation Requirements

Ventilation requirements include:

• Do not block or cover ventilation openings at the front and rear of an chassis. Never place an

chassis near a radiator or heating vent. Failure to follow these guidelines can cause overheating and affect the reliability and warranty of your chassis.

• Leave a minimum of 15.2 cm (6 inches) at the front and rear of each chassis to ensure adequate

airflow for cooling. No cooling clearance is required on the sides, top, or bottom of chassis .

• Leave enough space in the front and rear of an chassis to allow access to chassis components for

servicing. Removing a component requires a clearance of at least 38.1 cm (15 inches) in front of and behind the chassis.

Cabling Requirements

Cabling requirements include:

• Keep power and interface cables clear of foot traffic. Route cables in locations that protect the

cables from damage.

• Route interface cables away from motors and other sources of magnetic or radio frequency

interference.

• Stay within the cable length limitations.

• QXS Storage RAID chassis and expansion chassis are suitable for connection to intra-building or

non-exposed wiring or cabling only.

• QXS Storage RAID chassis and expansion chassis are suitable for installation in Network

Telecommunication Facilities and locations where the NEC applies. QXS Storage RAID chassis and expansion chassis are not suitable for Outside Plant (OSP) installations.

Management Host Requirements

A local management host with at least one mini-USB connection is recommended for the initial installation and configuration of a RAID chassis. After you configure one or both of the controller modules with an IP address, you then use a remote management host on an Ethernet network to manage and monitor.

NOTE: Connections to this device must be made with shielded cables – grounded at both ends – with metallic RFI/EMI connector hoods, in order to maintain compliance with NEBS and FCC Rules and Regulations.
